if you can see in the picture I uploaded the yellow character which if I shot it kind of strong it stuck in the green wall. it a collision shape problem or what else someone can somone can help? thanks.
If you enable collison shape mode, you can edit "start" collision, but there are also "if collide" node collision shapes. If you have complex character's node map, you might have even over 10 different collision shapes just for character.
yeah I familiar with that stuff but I think the problem here when I make a strong shot it got stuck. I checked all of my collision shapes and it happens also on the pool template.
