Yeah... that works! thanks! Now I don't have any more problems... But does anyone know if I can make a spring that's alredy "pressed in", so when I start it the spring press out instead of just sitting there untill something else press against it... You see, I'm trying to build a magazine for a gun, and the only way I know how to make the spring press up the bullets is to build a machine that insert each bullet after I've started the simulation And that's not how I want it!!

I've tryed that... then the joint falls down on the floor, but the thing I've jointed it to is still unmovable

Hello! I'm quite new at this and I can't make something that is jointed with for e.g. a hinge to move, how do I do it?
