What does cpBodyApplyForce() do?

[alexppp]

Hi,

I have a circular body with a certain moment of inertia anchored at its center to a static body with a pivot joint:



I'm applying the force as in the picture, but I'm not sure how the system is supposed to behave? In my program the body just accelerates indefinitely. I was expecting it to come to a standstill after about a quarter of a turn though?

Thanks in advance.

cpBodyApplyForce() adds a force to a body, but forces don't reset themselves. If you want them to, you need to call cpBodyResetForces() somewhere at the beginning of your step.
