I have a revolute joint set up as such in libgdx + box2d:
RevoluteJointDef rjd = new RevoluteJointDef(); rjd.initialize(body1, body2, arm.getWorldCenter()); rjd.motorSpeed = 100.0f; rjd.enableLimit = false; rjd.enableMotor = true; rjd.collideConnected = false; world.createJoint(rjd);
The joint displays and connects fine, but it never seems to turn or rotate. After some googling some people said to increase the motor speed, but I've turned that up to ridiculous values with still no rotations. The density of both body1 & body2 are set to 1.0f, so I'm not sure what else to do (both bodies are dynamic).
