I have been trying to make a simple two wheeled vehicle composed of two circles and a rectangle. When I try and create wheel or piston joints on the end of the rectangle that are connected to the circles, the anchor values seem wrong. When I view this with the physics debug draw on, I notice that the anchor joint on the rectangle is correct, but the anchor of the circle is wrong. When I print the values of anchorA and anchorB, they are identical. Shouldn’t physics.addJoint for piston and wheel take two anchor points instead of 1? They definitely shouldn’t have the same object relative anchor point. Also, as a side note, for these joints an anchor of 0,0 does not end up in the center like it should. Am I doing something wrong, or is there a way to change anchor points after the object has been created. Or is this bug the reason I haven’t seen any vehicle games done with corona.
