Roger, Rather than moving an object, think about using button icons. This is the basic process:
- on mouseDown: check the icon of the target, set the icon of a hidden, moving button to the same icon, set the icon of the target to 0, set a flag—isDragging--to true, show the hidden button - on mouseMove: if isDragging is true, set the loc of the moving button to the mouseLoc - on mouseUp: figure out which square you’re over, set the icon of that button to the icon of the moving button, hide moving button, set isDragging to false. I made a rudimentary chess game that uses this technique, check it out here: http://dight310.byu.edu/lesson_materials/07-arrays/chessGame-final-key.livecode Click the Clear Board and Setup Game buttons first to set up the game board array. Game state handlers are in the card script; game piece moving handlers are in the game board group script. Hope this helps.

How can I move an object (grab me on mouseDown) and have it snap to a grid (square on a board game) on mouseUp?
