The point of the ramp and fill handles was to demonstrate the difference between the motion tracking and what squeak usually does which is cursor position tracking. A lot else is going on in those examples, but it does demonstrate the abiltity to move the target along a constrained track and to keep moving it even as the cursor and target get out of sync. What I was trying for was that the target becomes the "cursor". Squeaks hand maintains a targetOffset but unless that is updated constantly it stops working as targets reach their constraints. So rather than updating target offsets 1) let the target supply the initial position fresh each move and 2) let the event then return how that targetpoint would be moved. Then 3) apply the constraints to the moved-point and 4) reposition the target accordingly. ===== the method #hasMoved is in the cs for completeness. MouseMoveEvents are generated frequently for timing and pacing reasons so often the events do not represent a real mouse move. The #deltaVector method is the result of the first attempt at these changes. Further iterations made me settle on #moveAndTug: tagretpoint. I probably use that most often in my coding projects.
