Hi,

I am working on a jigsaw puzzle in Opus Pro and wonder if there is any way to add the equivalent of a transform handle to each puzzle piece that can rotate the piece clockwise or counterclockwise. The piece would be already set up for drag and drop to be moved to the drop zone (jigsaw puzzle canvas). Can start the puzzle piece at an angle so that the player needs to rotate it in order to fit into the drop zone's target area.

But how to add CW and CCW rotation when a piece is selected?

Can conceive of putting the piece in a drag-able frame, have a non-visible group of 4 corner handles show when the piece is selected by mouse (see below). But how to create a script that can, once mouse down on only one of the visible handles, to rotate the piece CW or CCW? So far can't get my brain around this part. Maybe not possible?

Here's what a selected puzzle piece would look like with rotation handles:

You do not need to 'wrap' your brain around it. Just rotate your head and stick your ear in the appropriate mating piece.

You can start with the puzzle piece in normal orientation, and when mouse-over or when dragged have a random rotation applied.

I think the CW and CCW rotation can be easy -- if you could count on the User having a mousewheel mouse. You script the RegisterEventHandler to manage that.

However if you have to add rotation, drag & drop complicates that unless you don't mind restricting rotation to when the piece is still. In that case, the simplest rotator would be a vertical rectangle. I would set it up to Click on it and drag inside the object -- sort of like a virtual trackpad as on a laptop.
specifically:
You take the mouse-position upon click, and continue taking mouse-position as cursor moves inside the rectangle. You can simply allocate a rotation increment to the number of pixels the mouse is moved. (I say rectangle to that you have a confined space where this control applies. If you do not care about that, then forget the rectangle and simple have User hold down Ctrl key while dragging on Page -- pick up the Vertical movement pixels.)

If you really want the 'handles' -- that can be done too. Just a bit more work I think.

ETA: mousewheel play.

Hi Larry,

Thank you for these creative suggestions. I'll keep playing with the concepts, see what I can get to work.

Best Wishes,

I had a quick go, no idea if this is what you had in mind. A few ways of doing it, but I thought this may be the easiest.

Thank you.

Very interesting! I'll play with it, see if I can apply it to the puzzle.

Kind Regards,
