Physics Question

Hey all,

I have a ball falling from the top of the screen. It will bounce down various platforms on the way down. When the ball collides with the platforms (if it is falling fast enough) the platforms moves down on the Y Axis a few pixels. I changed the density on the platforms to 10k but they still move. The restitution and friction is at 0. Unchecking moveable isn't an option, as for some game instances it needs to.

What settings do I need to tweak to make the platform not move at all when the ball collides with it?

Thanks in advance.

try constraining the y when u dont want it to move down

Ended up doing that but I wanted to see if I could avoid a constrain.....what I finally settled on was just taking the collide behavior out completely and just told the ball to bounce if it overlapped or collided with a platform via changing its self.velocity.y to random (40,130). This way the ball still bounces but the platforms do not move because there is no collide rule.
