Collisions help, please!

Hey, i looked thru it and u aren't setting the collisions correctly. Your entity type says

Const cam_col=1 
Const ground_col=2 
EntityType cam1,cam ; cam should be cam_col
EntityType terrain,ground ; ground should be ground_col
Collisions cam1,ground,2,1

so it should read this

Const cam_col=1 
Const ground_col=2 
EntityType cam1,cam_col
EntityType terrain,ground_col 
Collisions cam1,ground,2,1

Hope that helps :o)
