oh and im not sure if this is the good place to post it

Welcome to the boards!

Basically what you will need to do is to place colliders on the game object which serve for collision detection.

Have a look at the physics pages from the docs, that’s should be a good starting point.

Also, there are a couple of (full game) tutorials around which should show you with examples how to achieve things.

thx for ur respond i cant try it now but tomorrow im sure going to use it.
thx:smile:
