Lille

A simple real-time strategy prototype demonstrating a dataflow-driven game loop with optional Bevy subsystems. Rendering is enabled with the render feature, while text rendering builds on top via the text feature. The project currently implements "Phase 1" of the migration roadmap, synchronising the legacy GameWorld state into Bevy and rendering static entities.

Features & usage

• Rendering: enable with render.
• Text rendering: enable with text (implies render).

Run the game:

cargo run -p lille --features render

Enable text:

cargo run -p lille --features text

Run tests that depend on rendering:

cargo test -p lille --features render -- tests/spawn.rs

Sprites that load PNG assets require Bevy's png feature; the render feature in this crate enables it (see Cargo.toml).

Game Setting

A fractured city of steel, brick, and neon — and your next battlefield.

A city with too many masters and too little future. Once the jewel of a vanished federation, its streets are now ruled by whoever can seize them — corporate militias, rogue syndicates, data cults, and the last vestiges of an irrelevant state.

The skyline tells the story: rusted iron arcades tower over flooded canals and cracked boulevards. Century-old stone buildings are patched with ferroglass and recycled scaffolds. Above them loom crumbling superstructures from a failed age of expansion, their data relays and skyways flickering with black market signals.

Beneath this decaying grandeur, commerce thrives in the margins. Street-level markets sprawl through abandoned plazas; encrypted auction houses operate out of gutted tram stations. Every corner offers a new opportunity — or an ambush.

Here, real power belongs to those who can move fastest, strike hardest, and control the flow of information. Squads operate in the open, armed, and augmented. Every mission risks crossing the unseen lines between factions — and starting a war you cannot finish.

Prepare to Deploy

Control is an illusion. Ownership is temporary. The streets belong to those who can take them — and keep them.

Build script

The build.rs entry point delegates to the build_support crate. This helper crate downloads the project font during compilation.

The font download uses the operating system’s certificate store for TLS verification. A valid set of root certificates must be present in the environment for the HTTPS request to succeed.

Isolated build support

Run the build support logic without compiling the whole game using the helper script:

./scripts/build_support_runner.sh

The script compiles the helper binary and executes it directly so CARGO_MANIFEST_DIR points to the repository root while running.

This performs the same steps as build.rs, downloading the font asset.
