math4gd2d
Utility math library for develping 2d games
...The library is not strictly about math, so some helpfull 2d gamedev relevant abstractions (like chains) are included too. Key features:
* Easy dealing with ranges, intervals
* Timers and callbacks
* Chains (for making chains of enemies, snakes, centipedes etc.)
* Some collision detection relevant stuff like SAT, Sweep and Prune, QuadTree-management, AABB computations, OBB computations, Point rotations, Braking convex polys in concav subpolies etc.
