How do I make it where when the start scene launches it presses a button automatically once?
Do you mean you want to simulate a touch to the screen? No idea. Do you mean you want the game to do something that is normally done by pressing that button? Then just write it to do that event as one of the at beginning of scene events, w/e it is.
When my game launches the music doesn’t play until I click left mouse button on any part of the game.
But the simulate buttons require an object selected
You could preload the music at the start of the scene
Ok, now the music is delayed. I guess it’s fine, it’s annoying tho
