The area where you want to delete the object, put a hidden object in it, but do not make it dynamic, and when the object you want to delete collides with the hidden object, give the delete command
Do the objects get deleted if you press and release the mouse button? If they’re a subevent of the mouse event then they’ll only get triggered once in the frame right after the mouse is released.
Thanks to your help this is solved.
Since I nested this under the mouse-click event, this was not triggered.
Placing it outside of the nesting solved this issue.
