# Ball gets stuck in corner when force lowered

Discussion and feedback on Construct 2

New to Construct, trying to make a ball that bounces around in a box
I have run into a couple of problems, when i reduce the angular force on the ball, and it hits directly in a corner it just sets there. Also, when it gets close to a corner at a slight angle, instead of bouncing off the 2nd edge, it rolls along it. Any advise?

Thanks!

Make sure ur collision polygon is not square. Are u using physics or bullet behaviour to make bounce?

Provide a .capx with the problem, so we can take a look at your problem directly.

Yea, it is set to circle. Here is an example. If you set the angle to 45, it just sticks in the corner.

@DTernes ,

The problem in your capx is that you are constantly applying a force on the ball, so, it's being pushed on the wall and can't bounce off it. Use an impulse instead and it will bounce as expected.
However, with a ball mass of 1, an impulse value lower than 0.7 will also produce a weird slide after the 1rst bounce. I don't know why.

I hope this helps!
