Bump
A fast, game-oriented collision detection library for Lua focused on axis-aligned rectangles.
What is Bump?
bump.lua is a collision detection library for Lua that specializes in axis-aligned bounding box (AABB) collisions. It is designed for 2D games where performance and simplicity are key, offering fast detection and basic collision responses like sliding and bouncing. The library prevents tunneling and supports spatial queries, making it a versatile tool for game developers.
Lua game developers, particularly those using frameworks like LÖVE, Corona SDK, or Cocos2d-x, who need efficient collision detection for tile-based games, platformers, or top-down adventures.
Developers choose bump.lua for its speed, minimal memory footprint, and game-focused design. Unlike heavier physics engines, it provides just enough collision handling for most 2D game genres without unnecessary complexity.
