Have you tried adding:
The left mouse button is clicked/touch is down
condition to the touch events?
I remember reading this solution a few weeks ago from Silver-Streak and while it’s not the same problem as yours, it would at least help you to troubleshoot the problem if it doesn’t help.
Oh very good, glad to hear it’s working. You’re using leftmouse released and cursor/touch for the scene changers, so is that working on mobile touch? For the third screenshot the way you have the different button touches as sub events of Touch/Left mouse is down looks good. It seems a strange place to have At the beginning of the scene though, haha, but my Gdevelop experience is not strong enough to know whether it’s a problem or just unusual or just me. I guess usually Beginning of the scene would be the top event in its event block.
