Problem:
\n– <\/strong>Players\u00a0 gun clips through walls and objects (since it has no collider and player can walk next to the wall)<\/p>\n

Solutions:<\/strong>
\n– Use 2 cameras (like in the http:\/\/unity3d.com\/learn\/live-training\/session\/merry-fragmas-multiplayer-fps-part-1<\/a> ), can be also used to draw other necessary effects on the same 2nd overlay camera (like muzzle flash)
\n– Modified shader that draws the gun on top of other objects (more info: http:\/\/docs.unity3d.com\/Manual\/SL-SubshaderTags.htm<\/a>l )
\n– Collider in the gun (but might cause problems when turning etc.)<\/p>\n
