progschj / TwinStick.cpp
Created March 26, 2013 10:05
A simple multiplayer "twin stick shooter" done during 3h hours at a gamespace.ch meet and make. I started with this: https://github.com/progschj/OpenGL-Examples/blob/master/02indexed_vbo.cpp and just added stuff from there. It has only been tested with two wireless xbox360 controllers.
