I made a demo based on the multitouch template. I tried to classify each marker by color, according to it’s position on the x axis. I did not do it in the best way possible, but I am satisfied.
The problem is that I can’t compare those different instances so that I can continue making my game. The different colors, are actually different animation frames. I tried to «stick» some extra sprites on each marker, so that I can compare them as different objects, but it didn’t work, because… I couldn’t do it correctly.
Here is a demo of the app and some screenshots.
