SpyHITW (Hybrid Plugin-Mod System)
SpyHITW is a highly optimized, hybrid "Hole In The Wall" minigame system built for Minecraft 1.21.11. It is split into a server-side Referee/Director (Paper Plugin) and a client-side Visuals/Physics engine (Fabric Mod) to achieve zero-lag visual interpolation and client-authoritative solid collisions.
It is a client-side dependency for SpyHITW-paper plugin.
spyhitw-fabric (Client Mod)
The Fabric mod intercepts instructions from the server to local visual renderers and physics loops:
- Network Packet Listener: Deserializes serialized byte streams and updates the local wall registry.
- Visual Renderer: Draws virtual walls using client-side BlockRenderDispatcher and WorldRenderEvents.AFTER_ENTITIES (rendering high-fidelity blocks with full refresh rate interpolation).
- Zero-Lag Physics Injection: Uses Mixin to inject solid VoxelShape collision boxes into Entity#findCollisions(). Forces the client to collide locally against moving walls, preventing phasing and rubber-banding.
- Dynamic Audio Engine: Automatically plays client-side music loops during active games, syncing with operator preference settings.
