hello, thanks in advance for the wonderful gb studio, well my question is that making my platform game, I put the character that shoots, but it goes through the walls, each shot, the shot is a ball, it does not hit the wall to that I mean, is there a solution so that when the crash the shot disappears, since putting actors eat space, I could use trigers but it eats memory, turned it around and around, since the control is very good and my game has been really good, I look powerless In that aspect.
