My first reaction is that why isn't a thumbstick object included in a game creation application from the beginning by Scirra, together with the other form controls? Since controlling a player character is absolutely vital to games. On the other hand, maybe there's a good reason why it doesn't exist, although I can't think of any...
Anyway, I've looked at a project that I found somewhere but it seems too complex and overwhelming to understand without explanation. I'm curious if there's other, maybe simpler solutions out there.
How do I create this myself in an easy and understandable way for a newbie? Is there a tutorial or a simple project showing how it's done?
