Collision Detection Functions for Processing Released!

UPDATE: these functions have been updated and moved to GitHub

Released today, version 0.9 of my 2d collision detection functions for Processing!

While some tools already exist, like the excellent Box2D, the source code is not easy to understand and the implementation is a bit complex. Other examples (equally great), like the line-line collision in the toxiclibs collection, use vector math which isn’t great for us “creative programmers” (ie: those like me who got bad grades in high school math).

Instead, these tools can be used as simple, one-line commands to determine whether two objects have collided. Designed for simple games and interactive systems, they are intended to be building blocks for larger projects.

Functions include:

  • Point/Point
  • Point/Rect
  • Point/Ball
  • Rect/Rect
  • Ball/Ball
  • Ball/Rect
  • Point/Line
  • Line/Line
  • Ball/Line

Maxwell’s Demon Game

Screenshots from the games I made yesterday for games++, the 12-hour game jam we hosted at Drift Station.

Inspired by Maxwell’s Demon, a thought-experiment with a box, separated by a wall with a hole in it and one side filled with gas.  The experiment asks the question of why does the gas “know” to go through the other hole and fill the second chamber so that it is dispersed evenly?

Written in Processing, the source code is here.
