On deserialization, vertex counts were fractional/NaN, bounding boxes were corrupted, and `modelBaseOffset = NaN` caused every instance to be rejected by `addInstanceToChunk`. + +2. **Tree Texture Corruption**: Three.js WebGPU has two texture upload paths: + - `DataTexture` → `writeTexture` (raw byte copy, no transformation) + - `ImageBitmapTexture` (fresh GLTF) → `copyExternalImageToTexture` (browser applies a color-space decode step) + + The `copyExternalImageToTexture` path performs a browser-side sRGB decode during upload, which corrupts the stored values when the destination is an `rgba8unorm-srgb` texture. `DataTexture` (from IndexedDB cache) uses `writeTexture` which copies bytes directly and renders correctly. + +**Fixes**: + +**ModelCache.ts** (`packages/shared/src/utils/rendering/ModelCache.ts`): +- **`extractAttr()` helper**: Deinterleaves `InterleavedBufferAttribute` by reading each component individually via `getComponent()`, producing contiguous typed arrays. Matches source typed array constructor (e.g., Uint16Array for skinIndex) instead of hardcoding Float32Array. +- **`ensureDataTexture()` helper**: Converts `ImageBitmapTexture` to `DataTexture` so all textures use WebGPU's `writeTexture` upload path (raw byte copy) instead of `copyExternalImageToTexture` (browser-side colorspace decode). Forwards `minFilter`, `magFilter`, `generateMipmaps`, `repeat`, `offset` to prevent mipmap/aliasing regression. +- **Fast DataTexture path**: `textureToPixelData()` now reads DataTexture pixel data directly without canvas round-trip. + +**GPUMaterials.ts** (`packages/shared/src/systems/shared/world/GPUMaterials.ts`): +- **Smooth diffuse ramp**: Replaced 4-band toon shading with continuous smoothstep diffuse ramp (warm highlights → cool shadows) plus narrow warm-tinted shadow terminator band. +- **Softened rim light**: Changed from binary step to smoothstep falloff for smoother edge highlights. + +**Key Files Changed**: +- `packages/shared/src/utils/rendering/ModelCache.ts` — Interleaved buffer deinterleaving, ImageBitmapTexture → DataTexture conversion +- `packages/shared/src/systems/shared/world/GPUMaterials.ts` — Smooth diffuse ramp tree shader +- `packages/shared/src/systems/shared/world/VegetationSystem.ts` — Consistent bracing, improved logging + +**Impact**: +- Mushrooms render correctly after cache clear (no more disappearing vegetation) +- Tree textures render consistently between fresh GLTF loads and cached loads +- Smoother tree lighting with continuous diffuse ramp instead of hard toon bands +- Proper mipmap filtering on all textures (no pixelation at distance) + +### Armor Pipeline POC3 (April 6-8, 2026) + +**Change** (PR #1142, Commits 87a4c6e-515c48c): Complete armor generation pipeline from VRM avatar to game-ready GLB. + +**Scope**: 26 files changed, +12,109 additions, -8 deletions in asset-forge package. + +**Core Features**: + +#### 1.

Clear inventory in-memory (`skipPersist=true`) +2. Clear equipment in-memory (via `clearEquipmentAndReturn()` with `tx` parameter) +3. Create death lock with dropped items and kept items +4. Transaction commits + +### Phase 2: Persist (After Transaction) + +After transaction completes: +1. Persist equipment clear to DB (`clearEquipmentImmediate()`) +2. Persist inventory clear to DB (`clearInventoryImmediate(skipPersist=false)`) +3. If persist fails, add to retry queue + +**Retry Queue**: +- Bounded to 100 entries (prevents unbounded growth) +- Single retry attempt per failure +- Drained once per tick in `processPendingRespawns()` +- Emits `AUDIT_LOG` event if retry also fails + +## OSRS Keep-3 System + +### How It Works + +In safe zones (non-wilderness), players keep their 3 most valuable items on death: + +1. **Value Calculation**: Items sorted by manifest value (descending) +2. **Stack Handling**: Each unit in a stack counts as one item +3. **Greedy Assignment**: Top N units across all stacks are kept +4. **Deterministic Tiebreaking**: Original index used when values are equal + +### Example + +```typescript +// Player dies with: +const inventory = [ + { itemId: "dragon_med_helm", quantity: 1 }, // value: 58000 + { itemId: "rune_scimitar", quantity: 1 }, // value: 15000 + { itemId: "amulet_of_glory", quantity: 1 }, // value: 10000 + { itemId: "lobster", quantity: 20 }, // value: 100 each + { itemId: "coins", quantity: 10000 }, // value: 1 each +];

Frozen Lockfile + +**Problem**: `bun install` without `--frozen-lockfile` tries to resolve packages fresh from npm, triggering rate limits. + +**Solution**: All workflows now use `--frozen-lockfile`: + +```yaml +- name: Install dependencies + run: bun install --frozen-lockfile +``` + +**Benefits**: +- Uses only committed lockfile (no npm resolution) +- Faster installs (no dependency resolution) +- Deterministic builds (exact versions from lockfile) +- Avoids npm rate limiting + +### 3. Tauri Build Splitting + +**Problem**: Tauri bundler attempts macOS code signing whenever `APPLE_CERTIFICATE` env var exists, even if empty. Non-release builds set it to `''` which caused `SecKeychainItemImport` errors. + +**Solution**: Split builds into separate Unsigned and Release jobs: + +**Before** (broken): +```yaml +- name: Build Desktop + env: + APPLE_CERTIFICATE: ${{ secrets.APPLE_CERTIFICATE || '' }} # Empty string breaks +``` + +**After** (fixed): +```yaml +# Unsigned builds (no signing env vars) +- name: Build Desktop (Unsigned) + if: github.event_name != 'release' + # No APPLE_CERTIFICATE env var + +# Release builds (signing env vars present) +- name: Build Desktop (Release) + if: github.event_name == 'release' + env: + APPLE_CERTIFICATE: ${{ secrets.APPLE_CERTIFICATE }} + APPLE_CERTIFICATE_PASSWORD: ${{ secrets.APPLE_CERTIFICATE_PASSWORD }} +``` + +**Platforms Affected**: +- Desktop (macOS, Linux, Windows) +- iOS +- Android + +### 4. macOS Unsigned Build Fix + +**Problem**: `--bundles app` is macOS-only, causing Linux/Windows unsigned builds to fail. + +**Solution**: Use `--no-bundle` for unsigned builds: + +```yaml +# Unsigned builds (all platforms) +- name: Build Desktop (Unsigned) + run: bun run tauri build --no-bundle + +# Release builds (macOS gets DMG) +- name: Build Desktop (Release) + run: bun run tauri build +``` + +**Result**: +- macOS unsigned: `.app` bundle only (no DMG) +- Linux unsigned: Binary only +- Windows unsigned: `.exe` only + +### 5. iOS Build Configuration + +**Problem**: Unsigned iOS builds always fail with "Signing requires a development team". + +**Solution**: Make iOS build job release-only: + +```yaml +- name: Build iOS + if: github.event_name == 'release' # Only run on releases +``` + +**Rationale**: iOS requires signing for all builds (even debug). No point running unsigned iOS builds - they always fail. + +### 6. Windows Install Retry Logic + +**Problem**: Windows runners experience transient NPM registry 403 errors during `bun install`. + +**Solution**: Add retry logic specifically for Windows: + +```yaml +- name: Install dependencies (Windows) + if: matrix.platform == 'windows-latest' + run: | + for ($i = 1; $i -le 3; $i++) { + bun install --frozen-lockfile + if ($LASTEXITCODE -eq 0) { + Write-Host "Install successful on attempt $i" + exit 0 + } + + if ($i -lt 3) { + Write-Host "Install failed, retrying in 30s... (attempt $i/3)" + Start-Sleep -Seconds 30 + } + } + + Write-Host "Install failed after 3 attempts" + exit 1 +``` + +**Backoff**: 30s between attempts (3 attempts total) + +### 7. Artifact Upload Splitting + +**Problem**: Release builds upload bundles, unsigned builds upload raw binaries - different artifact types. + +**Solution**: Conditional artifact upload based on build type: + +```yaml +# Release builds: Upload bundles (DMG, MSI, AppImage) +- name: Upload Release Artifacts + if: github.event_name == 'release' + uses: actions/upload-artifact@v4 + with: + name: release-${{ matrix.platform }} + path: packages/app/src-tauri/target/release/bundle/ + +# Unsigned builds: Upload raw binaries +- name: Upload Unsigned Artifacts + if: github.event_name != 'release' + uses: actions/upload-artifact@v4 + with: + name: unsigned-${{ matrix.platform }} + path: packages/app/src-tauri/target/release/hyperscape* +``` + +### 8. Matrix Job Filtering Fix + +**Problem**: Job-level `if` condition cannot reference matrix variables (matrix context not available until job runs). + +**Solution**: Remove invalid matrix reference from job-level condition: + +```yaml +# BROKEN +jobs: + build: + if: matrix.platform != 'ios' # matrix not available here + strategy: + matrix: + platform: [macos, linux, windows, ios] + +# FIXED +jobs: + build: + strategy: + matrix: + platform: [macos, linux, windows, ios] + steps: + -

The system was completely rewritten in March 2026 to fix critical bugs including SQLite deadlock, equipment duplication, and missing keep-3 mechanics. + +## Core Features + +### 1. OSRS-Style Keep-3 System + +In safe zones (non-PvP areas), players keep their 3 most valuable items on death: + +- Items are ranked by manifest `value` field +- Stacked items (quantity > 1) are handled efficiently without memory explosion +- Kept items are returned to inventory on respawn +- Dropped items go to gravestone for retrieval + +**Implementation**: `DeathUtils.splitItemsForSafeDeath()` +- O(n log n) complexity on unique item slots (not individual units) +- Greedy quantity assignment for stacked items +- Deterministic tiebreaking on original index when values are equal + +### 2. Two-Phase Persist Pattern + +Death processing uses a two-phase pattern to prevent database deadlock: + +**Phase 1 - Inside Transaction**: +- Clear inventory and equipment in-memory +- Create death lock with kept items +- Skip database persist (would cause nested transaction deadlock) + +**Phase 2 - After Transaction**: +- Persist equipment clear to database +- Persist inventory clear to database +- Retry queue handles failures + +**Why This Matters**: SQLite doesn't support nested transactions. The old code called `clearEquipmentAndReturn()` and `clearInventoryImmediate()` inside `executeInTransaction()`, each opening their own transaction, causing silent deadlock. + +### 3. Death Lock System + +Death locks prevent state desync during the death-to-respawn window: + +```typescript +interface DeathLock { + playerId: string; + deathPosition: { x: number; y: number; z: number }; + keptItems: InventoryItem[]; // For crash recovery + createdAt: number; + expiresAt: number; // Auto-expire after 5 minutes +} +``` + +**Purpose**: +- Prevent reconnect during death processing from corrupting state +- Store kept items for crash recovery (in-memory map is lost on server crash) +- Auto-expire stale locks (TTL: 5 minutes) + +**Crash Recovery**: If server crashes between transaction commit and persist completion, death lock persists kept items. On reconnect, system checks for active death lock and recovers kept items from database. + +### 4. Gravestone Privacy + +Gravestone loot is privacy-preserving (OSRS-accurate): + +- `lootItems` array is stripped from network broadcast +- Only `lootItemCount` (number) is synced to all clients +- Full loot data sent only to interacting player via `corpseLoot` packet +- Empty gravestone guard uses synced `lootItemCount` field + +**Why**: In OSRS, gravestone contents are hidden until interaction. Broadcasting full loot arrays would leak player wealth to all nearby clients. + +### 5. Persist Retry Queue + +Post-transaction persist failures are retried once: + +```typescript +interface PersistRetry { + playerId: string; + type: 'equipment' | 'inventory'; + timestamp: number; +} +``` + +**Behavior**: +- Single retry per failure (no infinite loops) +- Retries drained once per tick in `processPendingRespawns()` +- Track in-flight retries to prevent races with reconnect/new death +- Bounded queue (max 100 entries) to prevent unbounded growth +- `AUDIT_LOG` events on retry failure for ops visibility + +## Architecture + +### File Structure + +``` +packages/shared/src/systems/shared/combat/ +├── PlayerDeathSystem.ts # Main death orchestration (1,605 lines) +├── DeathUtils.ts # Pure utility functions +├── DeathTypes.ts # Type definitions +└── __tests__/ + ├── PlayerDeathFlow.test.ts # Death-to-respawn flow tests + └── DeathUtils.test.ts # Utility function tests (51 tests) + +packages/shared/src/systems/shared/death/ +├── DeathStateManager.ts # Death lock CRUD operations +├── SafeAreaDeathHandler.ts # Safe zone death logic +├── WildernessDeathHandler.ts # PvP zone death logic (future) +└── ZoneDetectionSystem.ts # Zone type detection +``` + +### Key Components + +#### PlayerDeathSystem + +Main orchestrator for death processing: + +```typescript +class PlayerDeathSystem extends SystemBase { + // Entry point - called by PlayerSystem.handleDeath + handlePlayerDeath(playerId: string, killedBy?: string): void + + // Core death processing (server-only) + private async processPlayerDeath(playerId: string, killedBy?: string): Promise + + // Post-death cleanup (equipment, inventory, gravestone) + private async postDeathCleanup(playerId: string, ...): Promise + + // Respawn handling + handleRespawnRequest(playerId: string): void + private initiateRespawn(playerId: string): void + private respawnPlayer(playerId: string): void + + // Tick-based processing + processPendingRespawns(): void // Called every tick +} +``` + +#### DeathUtils + +Pure utility functions (stateless, side-effect-free): + +```typescript +// XSS/Unicode/injection protection for killer names +function sanitizeKilledBy(killedBy: unknown): string + +// OSRS keep-3 with stack handling (O(n log n) on unique items) +function splitItemsForSafeDeath( + allItems: InventoryItem[], + keepCount: number +): { kept: InventoryItem[]; dropped: InventoryItem[] } + +// Position validation and clamping to world bounds +function validatePosition(position: Position3D): Position3D | null +function isPositionInBounds(position: Position3D): boolean + +// Constants +const GRAVESTONE_ID_PREFIX = "gravestone_" +const ITEMS_KEPT_ON_DEATH = 3 +const POSITION_VALIDATION = { WORLD_BOUNDS: 10000, MAX_HEIGHT: 500, MIN_HEIGHT: -50 } +``` + +#### DeathStateManager + +Database operations for death locks: + +```typescript +class DeathStateManager { + // Create death lock (with kept items for crash recovery) + async createDeathLock(playerId: string, deathPosition: Position3D, keptItems: InventoryItem[]): Promise + + // Check if player has active death lock + async getDeathLock(playerId: string): Promise + + // Clear death lock after respawn + async clearDeathLock(playerId: string): Promise + + // Cleanup expired locks (TTL: 5 minutes) + async cleanupExpiredLocks(): Promise +} +``` + +## Death Flow + +### Safe Zone Death (Keep-3) + +``` +1.

"use_wallclock|aresample" +``` + +### Stream Buffering on Viewers + +**Symptoms:** +- Viewers experience frequent buffering +- Stream quality drops + +**Cause**: Insufficient buffer size or zerolatency tune. + +**Fix** (commit 4c630f1): +```bash +# Use film tune instead of zerolatency +export STREAM_LOW_LATENCY=false + +# Increase buffer size to 4x bitrate +# This is now the default

+[RTMPBridge] FFmpeg exited with code=1 +``` + +**Cause**: Invalid arguments, missing codecs, or RTMP connection failure. + +**Fix**: +```bash +# Check FFmpeg logs +pm2 logs hyperscape-duel | grep -A

production/staging environments +``` + +**Cause**: JWT_SECRET not set in production. + +**Fix**: +```bash +# Generate secret +openssl rand -base64 32 + +# Add to .env or Railway environment +JWT_SECRET=your-generated-secret +``` + +**Note**: This is now enforced in production/staging (commit b56b0fd). + +### Stream Keys Not Working + +**Symptoms:** +- Stream keys configured but streams don't appear +- FFmpeg shows "Connection refused" + +**Cause**: Stale stream keys in environment override .env values. + +**Fix** (commit a71d4ba): +```bash +# The deploy script now explicitly unsets and re-exports +unset TWITCH_STREAM_KEY X_STREAM_KEY X_RTMP_URL KICK_STREAM_KEY KICK_RTMP_URL +unset YOUTUBE_STREAM_KEY +export YOUTUBE_STREAM_KEY="" +source /root/hyperscape/packages/server/.env + +# Verify keys are configured +pm2 logs hyperscape-duel | grep "STREAM_KEY" +# Should show: ***configured*** (not NOT SET) +``` + +### Solana Keypair Not Found + +**Symptoms:** +``` +Error: Keypair file not found: ~/.config/solana/id.json +``` + +**Cause**: SOLANA_DEPLOYER_PRIVATE_KEY not set or decode-key.ts not run. + +**Fix** (commit 8a677dc): +```bash +# Set environment variable +export SOLANA_DEPLOYER_PRIVATE_KEY="[1,2,3,...]" # JSON array +# OR +export SOLANA_DEPLOYER_PRIVATE_KEY="base58string" + +# Run decode script +bun run scripts/decode-key.ts + +# Verify +ls -la ~/.config/solana/id.json +solana-keygen pubkey ~/.config/solana/id.json +``` + +### Secrets Lost After Git Reset + +**Symptoms:** +- DATABASE_URL works initially but fails after deployment +- Stream keys stop working after git pull + +**Cause**: Git reset overwrites .env file. + +**Fix** (commit eec04b0): +Secrets are now written to `/tmp/hyperscape-secrets.env` before git reset: + +```bash +# In deploy-vast.yml +cat > /tmp/hyperscape-secrets.env << 'EOF' +DATABASE_URL=${{ secrets.DATABASE_URL }} +# ... other secrets +EOF + +# In deploy-vast.sh (after git reset) +cp /tmp/hyperscape-secrets.env /root/hyperscape/packages/server/.env +``` + +## Common Error Messages + +### "Failed to resolve module specifier" + +**Fix**: Update Vite config with polyfill aliases (commit e012ed2). + +### "WebGPU is not supported" + +**Fix**: Use Chrome 113+, Edge 113+, or Safari 18+. Check [webgpureport.org](https://webgpureport.org). + +### "CSRF token validation failed" + +**Fix**: CSRF now skipped for cross-origin (commit 8626299). Update server code. + +### "Connection refused" (database) + +**Fix**: Set DATABASE_URL, run database warmup (commit dda4396). + +### "Keypair file not found" + +**Fix**: Set SOLANA_DEPLOYER_PRIVATE_KEY, run decode-key.ts (commit 8a677dc). + +### "PulseAudio: Connection refused" + +**Fix**: Start PulseAudio, create chrome_audio sink.

Increase `LLM_TIMEOUT_MS` (default 3000ms) +2. Use faster model (TEXT_SMALL is already the fastest) +3. Switch to scripted fallbacks: `useLlmTactics: false` +4. Check LLM provider status + +### Taunts Too Frequent + +**Symptoms:** +- Messages spam chat +- Cooldown not working + +**Check:** +1. Verify `TRASH_TALK_COOLDOWN_MS = 4000` (4 seconds) +2. Check `lastTrashTalkTime` is being updated +3. Ensure `_trashTalkInFlight` guard is working +4. Look for multiple DuelCombatAI instances (should be one per agent) + +### Taunts Not Character-Appropriate + +**Symptoms:** +- Generic messages +- Doesn't match agent personality + +**Causes:** +- Character bio/style not set in ElizaOS character definition +- LLM not using character context + +**Solutions:** +1.

Check object pool availability (may be exhausted) + +**Fix**: +```typescript +// Increase pool size if needed +const POOL_SIZE = 12; // Was 8 +``` + +### Cooldown Stuck + +**Symptoms**: Button shows cooldown but server allows teleport, or vice versa. + +**Diagnosis**: +1. Check server logs for cooldown state +2. Verify `remainingMs` field in `homeTeleportFailed` packet +3. Check client is reading `remainingMs` correctly + +**Fix**: Server is authoritative - client should always sync to server state via `remainingMs` field. + +### Portal Not Grounded + +**Symptoms**: Portal floats above or sinks below player. + +**Diagnosis**: +1. Verify terrain system is ready (`terrain.isReady()`) +2. Check `getHeightAt()` returns valid values +3. Verify bone transforms are available + +**Fix**: Portal uses fallback chain: +1.

CORS Restrictions on Internal Endpoints + +**Change**: Internal betting endpoints restrict CORS to specific origin. + +**Impact**: Cross-origin requests from non-allowed origins will receive CORS errors. + +**Migration**: +```bash +# Server .env - set allowed origin +INTERNAL_BET_SYNC_ALLOWED_ORIGIN=https://your-betting-frontend.com +``` + +**Server Response**: +```http +Access-Control-Allow-Origin: https://your-betting-frontend.com +Access-Control-Allow-Credentials: true +``` + +### 3. Embedded Client Origin Validation + +**Change**: Embedded clients now validate `postMessage` origins against explicit allowlist. + +**Impact**: `HYPERSCAPE_AUTH` messages from untrusted origins are rejected. + +**Migration**: +```bash +# Client .env - set trusted embed origins +PUBLIC_EMBED_ALLOWED_ORIGINS=https://embed.example.com,https://partner.example.com +``` + +**Client Code**: +```typescript +// Old (accepts from any origin) +window.addEventListener("message", (event) => { + if (event.data?.type === "HYPERSCAPE_AUTH") { + config.authToken = event.data.authToken; + } +}); + +// New (validates origin) +import { isTrustedEmbedOrigin, parseHyperscapeAuthMessage } from "@/lib/embeddedAuth"; + +const trustedOrigins = resolveTrustedEmbedOrigins({ + currentOrigin: window.location.origin, + publicAppUrl: import.meta.env.PUBLIC_APP_URL, + embedAllowedOrigins: import.meta.env.PUBLIC_EMBED_ALLOWED_ORIGINS, +}); + +window.addEventListener("message", (event) => { + if (!isTrustedEmbedOrigin(event.origin, trustedOrigins)) { + console.warn("Ignoring message from untrusted origin:", event.origin); + return; + } + + const message = parseHyperscapeAuthMessage(event.data); + if (message) { + applyHyperscapeAuthMessage(config, message); + } +}); +``` + +### 4.

Vite 8 Polyfill Changes + +**Change**: Removed `vite-plugin-node-polyfills`, manual Buffer injection required. + +**Impact**: Solana and crypto libraries need manual Buffer global. + +**Migration**: +```typescript +// packages/client/src/polyfills/buffer-shim.ts +import { Buffer } from "buffer"; + +// Inject Buffer global for libraries that expect it +(globalThis as Record).Buffer = Buffer; + +export default Buffer; +``` + +**Vite Config**: +```typescript +// vite.config.ts + +// REMOVED +import { nodePolyfills } from "vite-plugin-node-polyfills"; +plugins: [ + nodePolyfills({ include: ["buffer"], globals: { Buffer: true } }), +] + +// ADDED +// Import buffer-shim.ts in your entry point +import "./polyfills/buffer-shim"; +``` + +### 6.

TSL Type Aliases + +**Change**: Added typed node aliases for better TypeScript support in TSL shaders. + +**New Exports** (added to `packages/shared/src/extras/three/three.ts`): +```typescript +export type TSLNodeFloat = ShaderNodeObject; +export type TSLNodeVec2 = ShaderNodeObject; +export type TSLNodeVec3 = ShaderNodeObject; +export type TSLNodeVec4 = ShaderNodeObject; +``` + +**Usage**: +```typescript +import type { TSLNodeFloat, TSLNodeVec3 } from '@hyperscape/shared'; + +// Use in TSL shader functions +function myShaderNode(input: TSLNodeVec3): TSLNodeFloat { + // ... +} +``` + +**Impact**: Better type safety for custom TSL shaders. No migration required unless you want to adopt the new type aliases. + +### 3. InstancedBufferAttribute Type Cast + +**Change**: Fixed type compatibility for `InstancedBufferAttribute` in HealthBars system. + +**Migration**: +```typescript +// ❌ Old (0.182.0) +const attribute = new InstancedBufferAttribute(array, itemSize); +geometry.setAttribute('name', attribute); + +// ✅ New (0.183.2) +const attribute = new InstancedBufferAttribute(array, itemSize) as BufferAttribute; +geometry.setAttribute('name', attribute); +``` + +**Files Changed in Hyperscape**: +- `packages/shared/src/systems/client/HealthBars.ts` - Added type cast for instancedBufferAttribute + +**Impact**: Only affects code using `InstancedBufferAttribute` with Three.js geometry. Add type cast if you encounter type errors. + +## Package Updates + +All packages have been updated to use Three.js 0.183.2: + +```json +{ + "dependencies": { + "three": "0.183.2" + }, + "devDependencies": { + "@types/three": "0.183.1" + } +} +``` + +**Affected Packages**: +- `packages/shared/package.json` +- `packages/client/package.json` +- `packages/asset-forge/package.json` +- `packages/impostors/package.json` +- `packages/procgen/package.json` +- Root `package.json` (overrides) + +## Benefits of Upgrade + +### Performance Improvements +- Faster WebGPU shader compilation +- Improved memory management for large scenes +- Better GPU resource utilization + +### WebGPU Enhancements +- More stable WebGPU device handling +- Better error messages for GPU issues +- Improved compatibility with latest GPU drivers + +### TSL Improvements +- Better TSL shader compilation +- More consistent GLSL/WGSL naming conventions +- Improved type safety for shader nodes + +### Bug Fixes +- Fixed various WebGPU rendering artifacts +- Improved texture handling +- Better geometry attribute management + +## Testing Your Migration + +After upgrading, verify your custom shaders and materials: + +1. **Check for `atan2` usage**: + ```bash + grep -r "atan2" packages/*/src --include="*.ts" --include="*.tsx" + ``` + +2. **Run the test suite**: + ```bash + npm test + ``` + +3. **Visual verification**: + - Start the game: `bun run dev` + - Check that all materials render correctly + - Verify post-processing effects (bloom, tone mapping) work + - Test in both development and production builds + +4. **Check for TypeScript errors**: + ```bash + npm run typecheck + ``` + +## Rollback Instructions + +If you need to rollback to Three.js 0.182.0: + +1. **Update package.json files**: + ```json + { + "dependencies": { + "three": "0.182.0" + }, + "devDependencies": { + "@types/three": "0.182.0" + } + } + ``` + +2. **Revert TSL changes**: + ```typescript + // Change back to atan2 + import { atan2 } from 'three/tsl'; + ``` + +3. **Reinstall dependencies**: + ```bash + bun install + bun run build + ``` + +## Additional Resources + +- [Three.js 0.183.0 Release Notes](https://github.com/mrdoob/three.js/releases/tag/r183) +- [Three.js 0.183.1 Release Notes](https://github.com/mrdoob/three.js/releases/tag/r183.1) +- [Three.js 0.183.2 Release Notes](https://github.com/mrdoob/three.js/releases/tag/r183.2) +- [Three.js TSL Documentation](https://threejs.org/docs/#api/en/nodes/Nodes) +- [CLAUDE.md](../CLAUDE.md) - Development guide with recent changes +- [AGENTS.md](../AGENTS.md) - AI assistant instructions with changelog + +## Support + +If you encounter issues with the upgrade: +1.

Position validation was added in PR #1094. + +## FAQ + +### Q: Can I use both PLAYER_DIED and PLAYER_SET_DEAD during migration? + +**A**: Yes, both events work during the deprecation phase. However, you should migrate to `PLAYER_SET_DEAD` as soon as possible to avoid breaking changes in the next major version. + +### Q: What's the difference between ENTITY_DEATH and PLAYER_SET_DEAD? + +**A**: +- `ENTITY_DEATH` is a generic event for any entity death (players, mobs, NPCs) +- `PLAYER_SET_DEAD` is player-specific and fires after death processing completes +- Use `PLAYER_SET_DEAD` for player-specific logic (respawn, gravestones, etc.) +- Use `ENTITY_DEATH` for generic death logic (kill tracking, loot drops, etc.) + +### Q: Does PLAYER_SET_DEAD fire for mob deaths? + +**A**: No, `PLAYER_SET_DEAD` is player-only. For mob deaths, use `ENTITY_DEATH` or mob-specific events. + +### Q: What if I need to run code BEFORE death processing? + +**A**: Subscribe to `ENTITY_DEATH` instead.

Global BFS Iteration Budget + +Shared budget across ALL pathfinding callers (combat follow, gathering, path continuation, player clicks): + +```typescript +// packages/shared/src/systems/shared/movement/BFSPathfinder.ts +const MAX_BFS_ITERATIONS_PER_TICK = 12000; // Shared across all callers +let _globalIterationsUsedThisTick = 0; +let _lastBudgetResetTick = -1; + +findPath(from: TileCoord, to: TileCoord, maxIterations = 4000): TileCoord[] | null { + const currentTick = this.world.currentTick ?? 0; + + // Reset budget at start of new tick + if (currentTick !== _lastBudgetResetTick) { + _globalIterationsUsedThisTick = 0; + _lastBudgetResetTick = currentTick; + } + + // Check remaining budget + const remainingBudget = MAX_BFS_ITERATIONS_PER_TICK - _globalIterationsUsedThisTick; + if (remainingBudget <= 0) { + this._lastIterationsUsed = 0; + return null; // Budget exhausted + } + + const effectiveMax = Math.min(maxIterations, remainingBudget); + + // ... BFS with effectiveMax iterations + + _globalIterationsUsedThisTick += iterationsUsed; + this._lastIterationsUsed = iterationsUsed; + return path; +} + +// Iteration tracking API +getLastIterationsUsed(): number { + return this._lastIterationsUsed; +} +``` + +**Impact**: Short paths are cheap (10-50 iterations), long paths cost proportionally. Budget prevents 25 agents from each running 4000 iterations simultaneously. + +#### 2.

Verify `BETTING_FEED_ACCESS_TOKEN` is set in server `.env` +2. Check token is passed correctly (Bearer header or `?streamToken=`) +3. Ensure token matches exactly (no extra whitespace) +4. Check server logs for "Betting feed auth failed" warnings + +**Test**: +```bash +# Bootstrap endpoint +curl -v -H "Authorization: Bearer $BETTING_FEED_ACCESS_TOKEN" \ + http://localhost:5555/api/internal/bet-sync/state + +# SSE endpoint +curl -v -H "Authorization: Bearer $BETTING_FEED_ACCESS_TOKEN" \ + http://localhost:5555/api/internal/bet-sync/events +``` + +### Renderer Health Always Degraded + +**Symptom**: `rendererHealth.ready` is always `false` + +**Solutions**: +1. Check `degradedReason` for specific issue +2. Verify streaming state is present (`hasStreamingState: true`) +3. Check agent snapshots have valid HP (`agent.hp <= agent.maxHp`) +4. Verify arena positions are not overlapping +5. Check loading overlay has dismissed (`loadingDismissed: true`) +6. Verify camera has locked to target (if `needsCameraLock: true`) + +**Debug**: +```typescript +// Client-side (browser console) +window.__HYPERSCAPE_STREAM_RENDERER_HEALTH__ +window.__HYPERSCAPE_STREAM_BOOT_STATUS__ + +// Server-side (check betting feed payload) +curl -H "Authorization: Bearer $TOKEN" \ + http://localhost:5555/api/internal/bet-sync/state | jq '.latestFrame.rendererHealth' +``` + +### SSE Connection Drops + +**Symptom**: EventSource closes unexpectedly + +**Solutions**: +1. Check server logs for "Slow client evicted" warnings +2. Verify client is consuming frames fast enough +3. Increase `STREAMING_SSE_MAX_PENDING_BYTES` if needed +4. Check network stability (SSE requires persistent connection) +5. Implement reconnection logic with `?since=` parameter + +**Monitoring**: +```bash +# Check active SSE clients +curl -H "Authorization: Bearer $TOKEN" \ + http://localhost:5555/api/internal/bet-sync/state | jq '.activeClients' +``` + +### Sequence Gaps + +**Symptom**: Missing sequence numbers in SSE feed + +**Solutions**: +1. Check `sourceEpoch` - if changed, server restarted (sequence reset) +2. Use bootstrap endpoint to get full replay buffer +3. Implement gap detection and re-bootstrap logic +4. Check `mode` field in SSE delivery: + - `"bootstrap"` - Full buffer (client is behind) + - `"incremental"` - Frames since `since` (client is caught up) + - `"reset"` - Client is ahead (server restarted) + +**Example**: +```typescript +let lastSeq = 0;

improvements made to Hyperscape's RTMP broadcasting system in February 2026. + +## Overview + +Hyperscape's streaming system has been significantly enhanced with better buffering, audio capture, multi-platform support, and improved stability.

Audio Capture via PulseAudio + +**What Changed**: Streams now include game audio (music and sound effects) instead of silent audio. + +**Implementation**: +- PulseAudio virtual sink (`chrome_audio`) captures browser audio +- FFmpeg reads from monitor device (`chrome_audio.monitor`) +- Async resampling prevents audio drift +- Graceful fallback to silent audio if PulseAudio unavailable + +**Configuration**: +```bash +# packages/server/.env +STREAM_AUDIO_ENABLED=true +PULSE_AUDIO_DEVICE=chrome_audio.monitor +PULSE_SERVER=unix:/tmp/pulse-runtime/pulse/native +``` + +**See**: [docs/streaming-audio-capture.md](streaming-audio-capture.md) for full setup guide. + +### 2. Improved RTMP Buffering + +**Problem**: Viewers experienced frequent buffering and stalling. + +**Solution**: Changed encoding settings for smoother playback: + +#### Encoding Tune Change + +**Before**: `zerolatency` tune (minimal buffering, unstable bitrate) +**After**: `film` tune (B-frames enabled, better compression, smoother bitrate) + +```bash +# Old (zerolatency) +-tune zerolatency + +# New (film) +-tune film +``` + +**Restore old behavior**: +```bash +STREAM_LOW_LATENCY=true +``` + +#### Buffer Size Increase + +**Before**: 2x bitrate (9000k buffer for 4500k bitrate) +**After**: 4x bitrate (18000k buffer for 4500k bitrate) + +```bash +# Old +-bufsize 9000k + +# New +-bufsize 18000k +``` + +**Impact**: More headroom during network hiccups, reduces buffering events. + +#### Input Buffering + +Added thread queue size for frame queueing: + +```bash +# Video input buffering +-thread_queue_size 1024 + +# Audio input buffering +-thread_queue_size 1024 +``` + +**Impact**: Prevents frame drops during CPU spikes. + +#### FLV Flags + +Added FLV-specific flags for RTMP stability: + +```bash +-flvflags no_duration_filesize +``` + +**Impact**: Prevents FLV header issues that could cause stream interruptions. + +### 3. Audio Stability Improvements + +**Problem**: Intermittent audio dropouts during video buffering. + +**Solutions**: + +#### Wall Clock Timestamps + +```bash +-use_wallclock_as_timestamps 1 +``` + +Maintains accurate audio timing using system clock instead of stream timestamps. + +#### Async Resampling + +```bash +-aresample async=1000:first_pts=0 +``` + +Recovers from audio drift when it exceeds 22ms (1000 samples at 44.1kHz). + +#### Removed -shortest Flag + +**Before**: `-shortest` flag caused audio to stop when video buffered +**After**: Flag removed, both streams continue independently + +**Impact**: Audio no longer drops out during temporary video buffering. + +### 4.

Soft CDP Recovery + +**Added**: Restart screencast without browser/FFmpeg teardown + +```typescript +// Try soft recovery first (no stream gap) +await this.restartScreencast(); + +// Only do full restart if soft recovery fails +if (stillStalled) { + await this.fullRestart(); +} +``` + +**Benefits**: +- No stream interruption during recovery +- Faster recovery (no browser restart overhead) +- Preserves browser state (cookies, localStorage) + +**Fallback**: Full restart if soft recovery fails after 3 attempts + +### 3. FFmpeg Restart Attempts + +**Increased**: 5 → 8 attempts + +```typescript +const MAX_RESTART_ATTEMPTS = 8; // Was: 5 +``` + +**Rationale**: FFmpeg can fail transiently due to: +- Network hiccups +- RTMP server temporary unavailability +- Encoder initialization delays + +8 attempts provides better resilience without infinite retry loops. + +### 4. Capture Recovery Max Failures + +**Increased**: 2 → 4 failures before full teardown + +```typescript +const CAPTURE_RECOVERY_MAX_FAILURES = 4; // Was: 2 +``` + +**Rationale**: Allows more soft recovery attempts before giving up and doing full browser/FFmpeg restart. + +### 5. WebGPU Best-Effort Initialization + +**Added**: Retry with default limits if GPU rejects custom limits + +```typescript +// Try with custom limits first +try { + const adapter = await navigator.gpu.requestAdapter(); + const device = await adapter.requestDevice({ + requiredLimits: { + maxTextureArrayLayers: 2048 // Custom limit + } + }); +} catch (error) { + // Retry with default limits (no requiredLimits) + const device = await adapter.requestDevice(); +} +``` + +**Rationale**: Some GPUs reject custom limits even if they support the feature. Best-effort approach tries custom limits first, falls back to defaults if rejected. + +**Result**: Always WebGPU (never falls back to WebGL in this path). + +### 6. WebGL Fallback for Streaming + +**Added**: Automatic WebGL fallback when WebGPU fails or is disabled + +```typescript +// packages/shared/src/utils/rendering/RendererFactory.ts +if (forceWebGL || disableWebGPU || !navigator.gpu) { + return createWebGLRenderer(); +} + +try { + return await createWebGPURenderer(); +} catch (error) { + console.warn('WebGPU failed, falling back to WebGL:', error); + return createWebGLRenderer(); +} +``` + +**Query Params**: +- `?page=stream&forceWebGL=1` - Force WebGL +- `?page=stream&disableWebGPU=1` - Disable WebGPU + +**Environment Variable**: +```bash +STREAM_CAPTURE_DISABLE_WEBGPU=true +``` + +**Use Cases**: +- Docker containers (WebGPU often unavailable) +- Vast.ai instances (GPU passthrough issues) +- Headless browsers (software rendering) + +### 7.

These changes ensure stable 24/7 streaming with automatic recovery. + +## Major Improvements + +### 1. PulseAudio Audio Capture + +**What**: Capture game audio (music and sound effects) for streaming. + +**Implementation**: +- User-mode PulseAudio (more reliable than system mode) +- Virtual sink (`chrome_audio`) for audio routing +- Automatic fallback to silent audio if PulseAudio fails +- XDG runtime directory at `/tmp/pulse-runtime` + +**Configuration**: +```bash +# Automatic in deploy-vast.sh +export XDG_RUNTIME_DIR=/tmp/pulse-runtime +export PULSE_SERVER=unix:/tmp/pulse-runtime/pulse/native +``` + +**See**: [docs/streaming-audio-capture.md](streaming-audio-capture.md) + +### 2. DATABASE_URL Persistence + +**Problem**: `DATABASE_URL` was lost during `git reset` operations in deployment. + +**Solution**: Write secrets to `/tmp` before git reset, restore after: + +```bash +# Before git reset +cp /tmp/hyperscape-secrets.env /root/hyperscape/packages/server/.env + +# After git reset +if [ -f "/tmp/hyperscape-secrets.env" ]; then + cp /tmp/hyperscape-secrets.env /root/hyperscape/packages/server/.env +fi +``` + +**Impact**: Database connection survives deployment updates. + +### 3. Database Warmup + +**Problem**: Cold start issues with PostgreSQL connection pool. + +**Solution**: Warmup step after schema push with 3 retry attempts: + +```bash +# Warmup database connection +for i in 1 2 3; do + if bun -e " + const { Pool } = require('pg'); + const pool = new Pool({ connectionString: process.env.DATABASE_URL }); + pool.query('SELECT 1').then(() => { + console.log('DB warmup successful'); + pool.end(); + }); + "; then + break + fi + sleep 3 +done +``` + +**Impact**: Eliminates cold start connection failures. + +### 4. Stream Key Management + +**Problem**: Stale stream keys in environment overrode correct values from secrets. + +**Solution**: Explicit unset and re-export before PM2 start: + +```bash +# Clear stale keys +unset TWITCH_STREAM_KEY X_STREAM_KEY X_RTMP_URL KICK_STREAM_KEY KICK_RTMP_URL +unset YOUTUBE_STREAM_KEY # Explicitly disable + +# Re-source from .env +source /root/hyperscape/packages/server/.env + +# Verify (masked) +echo "TWITCH_STREAM_KEY: ${TWITCH_STREAM_KEY:+***configured***}" +``` + +**Impact**: Correct stream keys always used, no more wrong-platform streaming. + +### 5. YouTube Removal + +**What**: YouTube streaming explicitly disabled from default destinations. + +**Why**: Focusing on Twitch, Kick, and X for lower latency and better live betting experience. + +**Implementation**: +```bash +# Explicitly unset YouTube keys +unset YOUTUBE_STREAM_KEY YOUTUBE_RTMP_STREAM_KEY +export YOUTUBE_STREAM_KEY="" +``` + +**To re-enable**: +```bash +# packages/server/.env +YOUTUBE_STREAM_KEY=your-youtube-key +YOUTUBE_RTMP_URL=rtmp://a.rtmp.youtube.com/live2 +``` + +### 6. Streaming Diagnostics + +**What**: Comprehensive diagnostic output after deployment. + +**Includes**: +- Streaming API state +- Game client status (port 3333) +- RTMP status file +- FFmpeg processes +- PM2 logs (filtered for streaming keywords) + +**Example Output**: +```bash +[deploy] ═══ STREAMING DIAGNOSTICS ═══ +[deploy] Streaming state: {"active":true,"destinations":["twitch","kick","x"]} +[deploy] Game client status: 200 +[deploy] RTMP status: {"twitch":"connected","kick":"connected","x":"connected"} +[deploy] FFmpeg processes: 3 running +[deploy] ═══ END DIAGNOSTICS ═══ +``` + +**Impact**: Faster troubleshooting of streaming issues. + +### 7. Solana Keypair Setup + +**What**: Automated Solana keypair configuration from environment variable. + +**Implementation**: +```bash +# Setup keypair from SOLANA_DEPLOYER_PRIVATE_KEY +if [ -n "$SOLANA_DEPLOYER_PRIVATE_KEY" ]; then + bun run scripts/decode-key.ts +fi +``` + +**Output**: Keypair written to `~/.config/solana/id.json` + +**Impact**: Keeper bot and Anchor tools work without manual keypair setup. + +### 8. Health Checking + +**What**: Wait for server health before considering deployment successful. + +**Implementation**: +```bash +# Wait up to 120 seconds for health check +while [ $WAITED -lt 120 ]; do + HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" \ + "http://localhost:5555/health" --max-time 5) + + if [ "$HTTP_STATUS" = "200" ]; then + echo "Server is healthy!" + break + fi + + sleep 5 + WAITED=$((WAITED + 5)) +done +``` + +**Impact**: Deployment only succeeds if server is actually running and healthy. + +## Deployment Flow + +### Complete Deployment Sequence + +```bash +1.

+description: "Multi-platform RTMP streaming with WebGPU capture" +icon: "video" +--- + +## Overview + +Hyperscape includes a production-ready streaming infrastructure for broadcasting AI vs AI duel arena matches to multiple platforms simultaneously (Twitch, Kick, X/Twitter, YouTube). + +## Architecture + +```mermaid +flowchart LR + A[Game Server] --> B[Stream Entry Point] + B --> C[Chrome CDP Capture] + C --> D[FFmpeg RTMP Bridge] + D --> E[Twitch] + D --> F[Kick] + D --> G[X/Twitter] + D --> H[Custom RTMP] +``` + +### Components + +| Component | Purpose | +|-----------|---------| +| **Stream Entry Point** | Dedicated `stream.html` / `stream.tsx` for optimized capture | +| **CDP Capture** | Chrome DevTools Protocol for frame capture | +| **RTMP Bridge** | FFmpeg multiplexer for multi-platform streaming | +| **Viewer Access Control** | Token-based access for trusted viewers | +| **Stream Destinations** | Auto-detection and management of RTMP endpoints | + +## Stream Entry Points + +### Dedicated Stream Client + +Hyperscape includes dedicated entry points optimized for streaming capture: + +**Files:** +- `packages/client/src/stream.html` - HTML entry point +- `packages/client/src/stream.tsx` - React streaming client +- `packages/client/vite.config.ts` - Multi-page build configuration + +**Features:** +- Optimized for headless browser capture +- Minimal UI overhead +- WebGPU-optimized rendering +- Separate from main game client + +**Access:** +```bash +# Development +http://localhost:3333/?page=stream + +# Production +https://hyperscape.gg/?page=stream +``` + +### Client Viewport Mode Detection + +The `clientViewportMode` utility detects the current rendering mode: + +```typescript +import { clientViewportMode } from '@hyperscape/shared'; + +const mode = clientViewportMode(); +// Returns: 'stream' | 'spectator' | 'normal' +``` + +**Use Cases:** +- Disable UI elements in stream mode +- Optimize rendering for capture +- Enable spectator-specific features + +## Stream Capture + +### Chrome DevTools Protocol (CDP) + +Hyperscape uses CDP for high-performance frame capture: + +**Configuration:** +```bash +# Capture mode +STREAM_CAPTURE_MODE=cdp # cdp (default), mediarecorder, or webcodecs + +# Chrome configuration +STREAM_CAPTURE_HEADLESS=false # false (Xorg/Xvfb), new (headless modes) +STREAM_CAPTURE_CHANNEL=chrome-dev # Use Chrome Dev channel for WebGPU +STREAM_CAPTURE_ANGLE=vulkan # vulkan (default), gl, or swiftshader +STREAM_CAPTURE_EXECUTABLE=/usr/bin/google-chrome-unstable # Explicit Chrome path (optional) + +# Capture quality +STREAM_CDP_QUALITY=80 # JPEG quality for CDP screencast (1-100) +STREAM_FPS=30 # Target frames per second +STREAM_CAPTURE_WIDTH=1280 # Capture resolution width (must be even) +STREAM_CAPTURE_HEIGHT=720 # Capture resolution height (must be even) +STREAM_GOP_SIZE=60 # GOP size in frames (default: 60) +``` + +### WebGPU Buffer Upload Fallback + +Handles `mappedAtCreation` failures gracefully: + +```typescript +// From packages/shared/src/utils/rendering/webgpuBufferUploads.ts +try { + buffer = device.createBuffer({ mappedAtCreation: true, ... }); +} catch (error) { + // Fallback: create unmapped buffer and write data separately + buffer = device.createBuffer({ mappedAtCreation: false, ... }); + device.queue.writeBuffer(buffer, 0, data); +} +``` + +**Impact:** Improves WebGPU stability on various GPU drivers. + +## RTMP Streaming + +### Stream Destinations + +Hyperscape supports multiple RTMP destinations with auto-detection: + +**Supported Platforms:** +- Twitch +- Kick (RTMPS) +- X/Twitter +- YouTube (deprecated) +- Custom RTMP servers + +**Auto-Detection:** +```bash +# Stream destinations auto-detected from configured keys +# Uses || logic: TWITCH_RTMP_STREAM_KEY || TWITCH_STREAM_KEY + +# Twitch +TWITCH_RTMP_STREAM_KEY=live_123456789_abcdefghij +TWITCH_RTMP_URL=rtmp://live.twitch.tv/app # Optional override + +# Kick (RTMPS)

Custom RTMP +CUSTOM_RTMP_NAME=Custom +CUSTOM_RTMP_URL=rtmp://your-server/live +CUSTOM_STREAM_KEY=your-key +``` + +**Explicit Destination Control:** +```bash +# Override auto-detection +STREAM_ENABLED_DESTINATIONS=twitch,kick,x +``` + +### FFmpeg RTMP Bridge + +The RTMP bridge multiplexes a single stream to multiple destinations: + +**Features:** +- Single encode, multiple outputs (tee muxer) +- Per-destination stream keys +- Automatic reconnection +- Health monitoring + +**Configuration:** +```bash +# RTMP Bridge Settings +RTMP_BRIDGE_PORT=8765 +GAME_URL=http://localhost:3333/?page=stream + +# Optional local HLS output +HLS_OUTPUT_PATH=packages/server/public/live/stream.m3u8 +HLS_SEGMENT_PATTERN=packages/server/public/live/stream-%09d.ts

+## Viewer Access Control + +### Streaming Viewer Access Tokens + +Secure access control for live streaming viewers: + +**Configuration:** +```bash +# Optional secret token for trusted viewers +STREAMING_VIEWER_ACCESS_TOKEN=replace-with-random-secret-token +``` + +**Access Levels:** +1. **Loopback Viewers**: Always allowed (localhost connections) +2. **Trusted Viewers**: Require access token +3. **Public Viewers**: Subject to public delay + +**Implementation:** +```typescript +// From packages/server/src/streaming/stream-viewer-access-token.ts +export function isAuthorizedStreamViewer( + request: FastifyRequest, + token?: string +): boolean { + // Loopback always allowed + if (isLoopbackRequest(request)) return true; + + // Check access token + const configuredToken = process.env.STREAMING_VIEWER_ACCESS_TOKEN; + if (!configuredToken) return false; + + return token === configuredToken; +} +``` + +**Usage:** +```bash +# Connect with access token +ws://localhost:5555/ws?viewerToken=your-secret-token +``` + +### Public Delay + +Configure delay for public streaming viewers: + +```bash +# Canonical output platform for timing defaults +STREAMING_CANONICAL_PLATFORM=youtube # youtube | twitch | hls + +# Override delay (milliseconds) +STREAMING_PUBLIC_DELAY_MS=15000 # Default varies by platform +``` + +**Platform Defaults:** +- YouTube: 15000ms (15 seconds) +- Twitch: 12000ms (12 seconds) +- HLS: 4000ms (4 seconds) + +## Deployment + +### Vast.ai Deployment + +Enhanced Vast.ai deployment with remote database support: + +**Auto-Detection:** +```bash +# deploy-vast.sh auto-detects remote database mode +# Checks for DATABASE_URL in environment +# Sets USE_LOCAL_POSTGRES=false when remote database detected +``` + +**Stream Key Management:** +```bash +# Explicitly unset and re-export stream keys before PM2 start +unset TWITCH_STREAM_KEY X_STREAM_KEY X_RTMP_URL KICK_STREAM_KEY KICK_RTMP_URL +source /root/hyperscape/packages/server/.env +bunx pm2 start ecosystem.config.cjs +``` + +**Why This Matters:** +- Prevents stale stream keys from shell environment +- Ensures PM2 picks up correct keys from .env file +- Required for CI/CD deployments + +### PM2 Configuration + +Production deployment uses PM2 for process management: + +```javascript +// From ecosystem.config.cjs +module.exports = { +

+ {itemName} + {quantity > 1 && ( + x{quantity} + )} +
+
+ {itemDescription} +
+ +``` + +### Equipment Tooltip with Bonuses + +```typescript + +
+ {itemName} +
+
+ {itemType} • {rarity} +
+ +
+
+ Attack: +{attackBonus} • Defense: +{defenseBonus} +
+
+ + {!meetsRequirements && ( +
+ Requires level {requiredLevel} Attack +
+ )} + +``` + +### Spell Tooltip with Rune Costs + +```typescript + +
+ {spellName} +
+
+ Level {spellLevel} Magic +
+ +
+ {spellDescription} +
+ +
+
Rune Cost
+
+ {runes.map(rune => ( + + {rune.quantity}x {rune.name} + + ))} +
+
+ + {isSelected && ( +
+ Currently Selected for Autocast +
+ )} + +``` + +## Integration with CursorTooltip + +The style utilities are designed to work with the `CursorTooltip` component: + +```typescript +import { CursorTooltip } from '@/ui'; +import { getTooltipTitleStyle } from '@/ui/core/tooltip/tooltipStyles'; + +function MyComponent() { + const theme = useThemeStore(s => s.theme); + const [hoverState, setHoverState] = useState<{x: number, y: number} | null>(null); + + return ( + <> + + + {hoverState && ( + +
+ Tooltip Title +
+ + )} + + ); +} +``` + +## Performance Considerations + +### Hover State Management + +Each tooltip-enabled component manages its own hover state: + +```typescript +const [hoverState, setHoverState] = useState<{x: number, y: number} | null>(null); +``` + +**Important**: `onMouseMove` fires at 60+ Hz, creating a new object on every event. For performance-critical components (e.g., bank slots with hundreds of items): + +1. **Throttle position updates**: Only update when position changes by >2px +2. **Lift state to parent**: Parent manages hover state, children call `onHoverStart`/`onHoverMove`/`onHoverEnd` +3. **Use `React.memo`**: Wrap slot components to prevent unnecessary re-renders + +**Example (lifted state pattern):** +```typescript +// Parent component +const [hoveredItem, setHoveredItem] = useState<{item, position} | null>(null); + +// Child component + setHoveredItem({item, position: pos})} + onHoverMove={(pos) => setHoveredItem(prev => prev ? {...prev, position: pos} : null)} + onHoverEnd={() => setHoveredItem(null)} +/> + +// Render tooltip in parent (single portal) +{hoveredItem && renderTooltip(hoveredItem)} +``` + +## Migration Guide + +### From Inline Styles + +**Before:** +```typescript +

+``` + +## Panels Using Unified Tooltips + +The following panels have been migrated to use the unified tooltip system: + +- **ActionBarPanel** - Action bar slots and rubbish bin +- **ActionPanel** - Draggable action slots +- **BankPanel** - Bank items, tabs, and equipment sidebar +- **EquipmentPanel** - Equipment slots and paperdoll +- **InventoryPanel** - Inventory slots and coin pouch +- **LootWindowPanel** - Loot items +- **PrayerPanel** - Prayer icons and descriptions +- **SkillsPanel** - Skill icons and XP progress +- **SpellsPanel** - Spell icons and rune costs +- **StorePanel** - Store items +- **TradePanel** - Trade slots and inventory items + +## Customization + +### Adding New Tone Colors + +To add a new tone (e.g., "info"), update `getToneColors()`: + +```typescript +function getToneColors(theme: Theme, tone: TooltipTone) { + switch (tone) { + // ... existing cases ... + case 'info': + return { + text: theme.colors.state.info, + background: `${theme.colors.state.info}22`, + border: `${theme.colors.state.info}4d`, + }; + } +} +``` + +### Extending Style Functions + +To add new style utilities, follow the existing pattern: + +```typescript +export function getTooltipFooterStyle(theme: Theme): React.CSSProperties { + return { + color: theme.colors.text.muted, + fontSize: '9px', + marginTop: '6px', + paddingTop: '6px', + borderTop: `1px solid ${theme.colors.border.default}30`, + opacity: 0.7, + }; +} +``` + +## Best Practices + +### 1. Use Semantic Style Functions + +Choose the style function that matches the content's semantic meaning: + +```typescript +// ✅ GOOD - semantic meaning clear +
{itemName}
+
{itemType}
+
{description}
+ +// ❌ BAD - using title style for everything +
{itemName}
+
{itemType}
+
{description}
+``` + +### 2. Avoid Redundant Spreads + +When the style function is the only property source, use it directly: + +```typescript +// ✅ GOOD +
Title
+ +// ❌ UNNECESSARY - spread adds noise +
Title
+``` + +### 3. Combine Styles Appropriately + +When combining with custom styles, spread the utility function first: + +```typescript +// ✅ GOOD - utility first, then overrides +
+ {description} +
+``` + +### 4. Use Consistent Spacing + +Follow the established spacing patterns: + +```typescript +// Title → Meta: 4px gap +
{title}
+
+ {meta} +
+ +// Divider: 8px margin + padding +
+ {content} +
+``` + +## Troubleshooting + +**Tooltip styles not applying:** + +**Cause**: Theme not passed correctly or style function not imported. + +**Fix**: Verify imports and theme access: +```typescript +import { getTooltipTitleStyle } from '@/ui/core/tooltip/tooltipStyles'; +import { useThemeStore } from '@/ui'; + +const theme = useThemeStore(s => s.theme); +``` + +**Inconsistent tooltip appearance across panels:** + +**Cause**: Panel using custom inline styles instead of utility functions. + +**Fix**: Replace inline styles with utility functions: +```typescript +// Before +
+ +// After +
+``` + +**Performance issues with many tooltips:** + +**Cause**: Each slot managing its own hover state causes excessive re-renders. + +**Fix**: Lift hover state to parent component (see [Performance Considerations](#performance-considerations)). + +## See Also + +- `packages/client/src/ui/core/tooltip/CursorTooltip.tsx` - Tooltip component +- `packages/client/src/ui/theme/themes.ts` - Theme definitions +- `packages/client/src/game/panels/` - Panel implementations using unified tooltips diff --git a/packages/evm-contracts/README.md b/packages/evm-contracts/README.md new file mode 100644 index 00000000..5a7fc566 --- /dev/null +++ b/packages/evm-contracts/README.md @@ -0,0 +1,363 @@ +# EVM Contracts + +Solidity smart contracts for the Hyperscape betting stack on EVM-compatible chains (BSC, Base). + +## Contracts + +### GoldClob + +Central Limit Order Book (CLOB) for binary prediction markets on AI agent duels. + +**Features:** +- Order book with price-time priority matching +- Binary YES/NO markets for duel outcomes +- Fee routing to treasury and market maker +- Claim mechanism for winning positions +- Garbage collection for expired orders + +**Deployment:** +```bash +bun run deploy:bsc-testnet +bun run deploy:base-sepolia +TREASURY_ADDRESS=0x...
