Help with bounce physics and hit test

1

This code does what I want except for all the vibrating once the mc has stopped bouncing. I guess it’s still bouncing. :ponder: I threw in a ‘delete.onEnterFrame’ if _y==floor, but that doesn’t give me the desired results. I want it to bounce for a bit then come to a rest with no vibration.

Can anyone help with this? I’d upload a basic .fla, but I’m restricted from uploads at work. All you need to do is create a 100x300 .fla, make a mc with the instance name of box_mc, place it at 10y, 25x and paste the code into the actions panel.

ActionScript Code:
[FONT=Courier New][LEFT][COLOR=#0000FF]floor[/COLOR] = [COLOR=#000080]250[/COLOR];

bounce = [COLOR=#000080]0[/COLOR].[COLOR=#000080]2[/COLOR];
