plz help how do I make the character just jump when I hit the screen
How do you mean ‘hit the screen’? As in tap the screen? Then you’ll need an event with the conditions of ‘A new touch has started’ and ‘Trigger once while true’. The Action itself depends on how you are making the character move. Give us a bit more of a clue to how you are doing that, and maybe we can help a bit further.
