I want to hide an item when the player touches it.. for example, Mario gets a coin.. the coin disapears and 1 is added to the coin counter
I just want the code as to how to hide an entity when the player mesh colides with it..
You don't just want to hide it, you want to delete it. So use CountCollisions every frame to detect when the player has collided, then use CollisionEntity to get the coin collided against, and finally use FreeEntity to delete the coin.
thanks jhocking for your sugestion.. and Wolron, I know how the free entity code works, I just dont understand how to apply it through a colision... though jhocking's advice has given me more information to work with, I'm still stubbed as to how to place the code into my current work..
here's my coding so far, take note.. I made the spheres coins, and I'm not really using Mario, but a white sphere named Bob.. this is just so I can attempt to build a decent 3D engine

can someone explain to me how to place the code into my current code?
The code below *should* work, though i haven't had time to test it.

hey, sweet!
thanks, Diablo **bows** ^_^ If I ever finish a game in 3D, I'll give you credit somehow
Best watch with collisions though, as the collision will have a collision response, stopping the player whilst he touches the coin. You can get around that by simply doing a distance check between the player and the coin. Distance checks are super fast and act just like sphere to sphere collisions, without the collision response :o)
yes,
thats what i'm using with my latest project.
though, i think that if you update once you have acted upon the collision you wont have the problem of getting more 'points' than you wanted to give.
