Newton's Laws

I made the following animation (based on a blender tut in 3D World Issue #95) :

As you see, the ball is going slow at it crashes into the bricks, but then it speeds up again! How can I make the ball lose kinetic energy as it crashes into the bricks instead of having a constant kinetic energy?


Could you take a screenshot of your logic setup or explain what forces you’re using? I don’t have the mag issue.

ok, they are attached!


Deselect the button with three dots on the always sensor. You will have to turn up the force value to counteract this though. What is happening at the moment is that the always sensors keeps on triggering and add more and more force to the object. You should just have an initial force instead. Depressing the button makes it only fire once.

thanks a bunch hunter - I’ll give it a shot and post the results.

ok, just clicking on the three dotted button didn’t work. But switching it to trigger on a mouse click does work.

here’s the finished result:

If you don’t want to use the mouse sensor, you could try this set up. (Just pay atention to what’s circled.):slight_smile:

EDIT: Oops! I forgot to maximize the property sensor.:o Basicly it test to see if the property “int” is true.

thanks, I’ll have to give that a shot
