collision problem

I can't get my camera to collide with my level. It just goes straight trough all geometry. I think I am on the right track here , but I am new to programming, so if someone could help me out , cheers
obviously I don't need to collide with the skybox , just the village mesh.Did n't qute understand the 'pick' stuff either.

RenderWorld

Text 0,0,"Use cursor keys to move around the village"

you have no UpdateWorld before the RenderWorld. UpdateWorld performs all collisions :)

great that works, thanks a lot DrakeX.
