Hello everyone! I'm quite new to the mobile programming and now stuck on a problem. My goal is to be able to flick an object, like a ball, that moves then towards the direction of the flick. I tried to implement this with the event "Flick" and then point towards direction "diff X and diff y". And then set speed 5. Sadly the game crashes every time with the argument that diff X has never been seen before. Can maybe someone explain me how to do it correctly? Thank you very much.
