i'm losing myself in this...
Situation: Working on a game in cocos2d with box2d and I have a ropejoint between one fixed body and one dynamic body.
When I drop the dynamic body is swings from left to right and then from right to left due to the gravity in the world.
The problem: The swings are getting shorter and shorter till finally the dynamic body hangs still beneath the fixed body. This is normal behavior but I need it to keep swinging.
My thoughts: I think I need to apply a tangential force to the ropejoint in the direction of the swinging but how to do this is a mystery for now :)
EDIT 1 The swinging does not have to be in perfect balance, it just can't slowly die.
