Spinning Coin/Puck
I am trying to make a hockey puck spin on a surface on its edge and fall flat on its face in a realistic manner. I can’t seem to do it by just moving the axis around. Does anybody know of a way to do this or has done something similar with a coin or something.
Cheers,
Brian

It’s pretty easy, it’s just one rotation (the coin falling over) with the coin spinning. You just have to put the coin in a null and spin that to make it easily controllable. Here’s an example I just made.

The only tricky part is the coin rotates on it’s center which leaves it in the air if it’s not moved down but a linear down motion is wrong – you have to tweak the F-Curves to keep the coin on the ground. Check the F-Curves for the coin.
You could just tweak the values to adjust the number of spins and the speed of fall but this is the general idea.

a better way, two nulls and rotate the coin falling around it’s edge- recenter it as it falls with the extra null. Keeps the coin on the ground with out F-Curve tweeking
