collision problem in rpg

hi i am currently working on RPG game but have some problem in collisions like when my Player is crossing through a tree it will go underneath from tree but when it goes through back of tree it goes through inside the trunk of tree I mean trunk appears above from my Player how to fix this please help..

I'm not sure exactly what you want to happen but it sounds like a layer problem, make sure the player is on a layer above the tree layer.

thank you but I have already done that..

You'll have to share a screenshot, capx or some other information so we can see the issue.

well sorry for taking your time but problem has been solved
