blackhornet Thanks, sometimes i use trigger once to stabilize performance after all, so i removed trigger once to make it perfect. I would need to know more how to spawn another sprite once time.
7Soul That's perfect, recently i got a new problem, If I implement spawn blue boxes from magenta sprites when they are touched, they generate more than once blue boxes could make terrible performance, otherwise i put trigger once, it only spawns one object, not twice or multiple times at once time.
How to fix it?
