An annotation processor that generates network packet classes and handler methods from @Remote annotations on interfaces. It reduces boilerplate by automatically creating serialization, dispatch, and registration code for multiplayer RPC calls. The pattern could be extracted to generate any RPC layer in a Java project, though it currently depends on internal javac APIs, which is a fragility risk.

Contains a generic A* pathfinding implementation (astar method) that works on a tile grid with custom cost functions, a node limit, and an optional heuristic. It also includes dynamic programming for optimal bridge placement and path normalization. The algorithm is independent of the game's data structures and can be extracted for any grid-based pathfinding need, such as floor planning or routing problems.

A chunk-based floor tile renderer that maintains a cache of vertex arrays for fixed-size 30x30 tile regions. It supports dynamic and static layers, dirty flag tracking for efficient updates, and custom vertex packing (two floats for position + UV). The chunking and caching pattern is a classic optimization for tile-based games and can be reused in any 2D tile engine requiring high performance rendering with infrequent recomputation.
