Actually Nevermind, you could change the gravity because a while back I was working on a project and I had the same issue but I just increased the gravity. Though when you increase the gravity it affects the other objects.
the gravity for the test was about -59.2 and to access angular and linear damping in code you just do this.entity.rigidbody.angularDamping = number; or this.entity.rigidbody.linearDamping = number;
There is just one thing left: When I jump and move at the same time, it goes way too fast. Can I set the movement in the x- and z-axis to linear and the jump on the y-axis to angular?
Let me try to explain: When I jump, my code changes, like you suggested me, angularDamping to 0.99 and linearDamping to 0 (well, except for the numbers). The problem is that when I jump, I also move on the x- and z-axis with an angular movement. I tried to change the angularFactor to (0, 1, 0) but it still won’t work.
Do you understand now? And if yes, have you got a solution to that?
