If you set a slider's limits to -1 and 1, the slider will only allow the bodies it joints to move apart one unit in either direction. Without limits or motors, the slider will allow the two objects to slide apart to infinity. On a related note... There is a bug in the physics library that can cause objects to spin faster and faster until they explode or fall to the ground. It's generally not a problem, but sliders with limits seem to cause this bug to appear more often. -- Nate Waddoups Redmond WA USA http://www.natew.com
