Peterwolf's groundworks conveyor belt

[0.1.1+26.3] - 2026-10-28

Performance & Optimization

• Massive Chute Discharge Search Optimization: Added an immediate horizontal AABB bounding box pre-filter in findReceiverUnderChute and findLoadedUnderChute. Eliminated up to 200 redundant vertical raycast checks per conveyor belt on every server tick, removing an \(O(N^2)\) server tick bottleneck when many belts operate simultaneously.
• Cached Collision Geometry: Added lazy caching of collisionParts in ConveyorBeltEntity. Eliminated per-tick and per-collision trigonometry and continuous new AABB object allocations.
• Removed Redundant Client Tick Recalculation: Removed updateBoundingBox() from client tick(), updating bounding boxes only upon placement, completion, height adjustment, or network sync.
• Fast Air Skip in Hopper Ingestion: Added immediate state.isAir() checks in ingestHopperTerrain on both conveyor belts and truck dump hoppers, avoiding reflection and cell storage lookups when no blocks are overhead.
• Zero-Allocation Custom Geometry Rendering: Rewrote ConveyorBeltStreamRenderer to emit vertices directly with precomputed normals, eliminating millions of Vector3f and faceNormal heap allocations per second and solving GC pause stuttering during rendering.
• Cached Network Deserialization: Cached deserialized parcel lists and composition data on the client, eliminating thousands of String.split regex parsing calls per second in extractRenderState.
• Fast Parcel Serialization: Replaced slow String.format calls with fast numeric rounding in BeltParcel.serializeList.
• Loaded Conveyors List Registration: Replaced CopyOnWriteArrayList.contains() per-tick server checks with a boolean registration flag.
