i am trying to create a see-saw.
but i don't understand how to correctly use joints to attach the board to the base.
The base is simply a Quad rotated 45
Maybe this would help
RotationalJointAxis joint = physicsSpace.createJoint().createRotationalAxis();
However I have on experience with joints yet.
ah, ok this works:
there is also a good joint example in physics Lesson7.
joint = space.createJoint();
// we want free rotation around the Z Axis
RotationalJointAxis axisZ = joint.createRotationalAxis();
axisZ.setDirection(Vector3f.UNIT_Z);
// make the joint unbreakable
joint.setBreakingLinearForce(Float.POSITIVE_INFINITY);
joint.setBreakingTorque(Float.POSITIVE_INFINITY);
joint.attach(dynamicBoard);
// set the anchor of the joint to the location of the seesaw
joint.setAnchor(dynamicBoard.getWorldTranslation());
