My object won't fall with gravity.... (Not A Game)

I have sketched up an animation for a flash intro to my site. But for some reason, I have run into a problem. My object won’t fall at all.

I’m trying to replicate the coin effect as if dropping on the floor, but I seem to have forgotten how to do it. I have resorted to doing it by hand, but I know there’s a better and smoother way, possibly with the physics engine. Can someone please help!

enable dynamics and rigidid body in the gamelogic buttons

also set the bound type there

in the game menu choose to bake physics

SAVE YOUR FILE!!!

hit P to start the game engine, and wait for as much stuff to happen as you want. Hit esc and your ipos will now exist.

IT WORKED! Thank you so much… you’re teh shiz!
