[Bug]: Auto pickup protection not working with OrbisGuard-Mixins

[derrickmehaffy]

Plugin Version

0.6.0

Operating System

Linux (Debian/Ubuntu)

Bug Description

Auto pickup of floating items (walking over dropped items) is not being blocked in SafeZones even when the ITEM_PICKUP flag is set to OFF.

The PlayerItemEntityPickupSystemMixin from OrbisGuard-Mixins is not being triggered, despite:

• HyperFactions correctly registering the pickup hook in orbisguard.hook.registry
• Other OrbisGuard mixins (durability, death, harvest) working correctly
• Hyxin loading OrbisGuard-Mixins properly

Evidence:

• orbisguard.mixin.pickup.loaded = null (should be true if mixin loaded)
• No logs from the pickup hook's check() method when picking up items
• Other mixin properties ARE set (e.g., orbisguard.mixins.loaded = true)

Steps to Reproduce

1. Create a SafeZone with /f admin zone create test safezone
2. Set item pickup flag OFF: /f admin zone flag test item_pickup false
3. Enable admin bypass and drop an item in the zone
4. Disable admin bypass (/f admin bypass)
5. Walk over the dropped item
6. Item is picked up despite flag being OFF

Expected Behavior

Walking over dropped items in a SafeZone with ITEM_PICKUP: false should NOT pick up the item. The PlayerItemEntityPickupSystemMixin should intercept the pickup and call HyperFactions' registered hook to check permissions.

Logs

[HyperFactions] Registry state at startup:
  orbisguard.mixins.loaded = true
  orbisguard.mixin.pickup.loaded = null    <-- Should be "true"
  orbisguard.mixin.harvest.loaded = true
  orbisguard.mixin.durability.loaded = true

No pickup hook logs appear when walking over items (hook is never called).

Code Snippets

Hook registration in OrbisMixinsIntegration.java:

PickupHookWrapper hook = new PickupHookWrapper(callback);
registry.put(PICKUP_HOOK_KEY, hook);
Logger.info("Registered pickup hook with OrbisGuard-Mixins");

Mixin configuration in orbisguard-mixins.mixins.json:

{
  "mixins": [
    "PlayerItemEntityPickupSystemMixin",
    ...
  ]
}

Additional Information

What Works:

• ✅ F-key pickup protection (via InteractivelyPickupItemEvent)
• ✅ Block harvest drop protection (via BlockHarvestUtilsMixin)
• ✅ Crop/berry harvest protection (via BlockUseProtectionSystem)
• ✅ Item drop protection (via ItemDropProtectionSystem)

What Doesn't Work:

• ❌ Auto pickup of floating items

Dependencies:

• OrbisGuard-Mixins v0.7.7
• Hyxin v0.0.11

Possible Causes:

1. Mixin injection point mismatch (method signature changed in server update?)
2. Class loading order issue
3. Hyxin not transforming this specific class

Workaround: None - auto pickup cannot be blocked without the mixin working. Requires coordination with OrbisGuard developers.
