Game Engine Problems

I’m currently working on a game, but i’ve been having some problems.

First of all i’m in first-person and I want my gun to render over everything else. I’ve read other threads pertaining this issue but it was either problematic or didn’t explain it properly.

The second problem is there a way to make a character-physics object interact with a dynamic/rigid body? The only way I could make this work is repeatedly jumping on it.

Any ideas on how to fix these? :frowning:
