I am trying to port the Particle Emitter by Michael Daley to GLKView and found a XCode project where he did this on github - unfortunately heavily bound inside a nice little game.
Now I tried to take only the particle emitter out of his game project to reuse it (I need it in 2D) and I made it up to a state without any compile error - but couldn't see nothing...
Here is the project file. Could anybody tell me why there is no particle emitter visible? thnx!
