I have this code below, where an image is bouncing around 4 walls.
But I don't want my image to rotate at all, but I would like to have my image bounce in X+Y direction when it hits a wall. Atm it bounces in X+Y the first time and then it's only X or Y direction. Anyone else with this problem?
I tried setting the cueball in SimplePool to isFixedRotation = true and the same thing happens there, the first bounce at a wall is correct and then it's bouncing only in X or Y direction depending on which wall it hits.
Can anyone help me? How can I get an image to bounce around with physics but without rotation of the image?

If I remove the friction on the wall it seems to work as it should.
