Collision detection for LÖVE
HC is a pure Lua library to simplify collision detection.
It supports a variety of scale- and rotatable shapes: Rectangles, (non self-intersecting) polygons, circles and points.
In contrast to love.physics, HC will only detect collisions, but not resolve them - you can decide how you want to respond to a collision.
If you have trouble using love.physics for collision detection or if you feel the ten-ton hammer is too much, HC might be the right choice.
