How do I to improve the object collision?

Hi everyone!

I’ve got a issue about the collision between a “platform” behavior object and the gravity center object, a Solid.

Here the demo>

So, I manage to move the object “control” around the circle or “nexo” simulating gravity. However, “control” is shaking all the time. I think is about the gravity and the edge of the “nexo”. I tried to sort it out adding more points to the collision area, but didn’t work.

Any ideas?, maybe there is a better system to do this than Gravity.

Your "character" is always in the same place. Is it really that you need a bump here?

Why not position in the center of the screen slightly behind the ball? No collision.

Your method a little tweaked
