I have a student who wants to detect when a sprite in a canvas is dragged and released. There’s a “click” event and a “pointer down” event but no “pointer up” or “touch up” event. Is there some clever way to determine this? My student is making a jigsaw puzzle game and wants the puzzle pieces to snap to grid when released. I’m helping her with the math for snap-to-grid but failing to find a way to create an event for that. ---

Turns out there is a block for this: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/7/4790b21146555422d6bc506c52947854021ac8e6.png) It would be nice if the event name matched the button/image event names (e.g. “touch up”). ---
