i want to make barriers and solid objects that you cant go through. I am working on a fps and with out this it would make no sense. All help would be appreciated.

Alice is a pain when it comes to collision detection. You can use an if/else structure and use the "is within [proximity]" world-level function as the condition. Then if it is within the proximity, the object will move away from the object. Else, do nothing.
