joint:getAnchorA( )
Description:
A function that returns the (x,y) coordinates of the joint’s anchor points within objects A and B, which are the two joined objects. The values are given in the local coordinates of each object, so an anchor point at the center of the object would be at position (0, 0).
Syntax:
x, y = joint:getAnchorA( )
Example:
x, y = myJoint:getAnchorA() x, y = myJoint:getAnchorB()
Returns:

AnchorA is the position of the target point.
AnchorB is the global position the of anchor point on the physical object which is being dragged.
