But the effect and the speed of the ricochet should vary on how fast the mouse-active hits that object. Can anyone tell me a formula to do that? http://create-games.com/project.asp?id=1549

Probably a better way would be to track the mouse's X and Y speed with two counters that update with the difference between its last value and the new value--that'll give you a speed. Or was that the question? O_o Edited by OMC

XKnockSpeed, YKnockSpeed, LastX, LastY, ObjectXSpeed & ObjectYSpeed are alterables values: +Always set XKnockSpeed to: XMouse-LastX +set YKnockSpeed to: YMouse-LastY +set LastX to: XMouse +set LastY to: YMouse Mouse-Active collides with objects +Set ObjectXSpeed to: XKnockSpeed +Set ObjectYSpeed to: YKnockSpeed Then move the objects according to their X and Y Speed values. ...

Wouldn't you still need to find the direction? ...

Failing that, make a custom one.. take a window of time.. like, say, in the past 0.05 seconds, then get the distance rolled within that period, and reset and take a new value every 0.05 seconds. Then speed = (distance in past 0.05 seconds)*X Set X to any number you like. Disclaimer: Any sarcasm in my posts will not be mentioned as that would ruin the purpose. It is assumed that the reader is intelligent enough to tell the difference between what is sarcasm and what is not.

The Move Safely object moves an object from A to B while checking the steps in between. I think you should be prepared for a lot of wrestling with MMF just to get this to work. Even once you've got the mouse following code sorted, you'll have to apply some physics to work out the collisions. //
