So, I'm making a autorunner game, and sometimes the character won't jump. Any ideas how to solve it?
We are going to need a lot more information - preferably a .capx - before we can answer this.
Your question is akin to telephoning a mechanic and saying "my car won't start, what's wrong"? Without seeing it, or having a lot more information, how can he know?
Please either show your events for the movement or upload a .capx so we can help you properly.
