Welcome! I-Spy (Hidden objects) is an educational puzzle that is more than just seek-and-find activities.
  • Say you are creating and randomly placing several instances of the same base object. How would you detect an overlap between the current (picked) instance and another instance previously placed?

    I tried the obvious condition "Object is overlapping Object" condition, but it never triggers, though overlaps are definitely happening.

    Edit: I should mention that the objects are being created in a loop, so detection should go in there.

  • You can sort of do what you want with families (put the object in a family and then do Object is overlapping Family), however you'll still run into the problem with this in a loop, because the sprite that was just created isn't available yet when the event to do the overlap check is called.

    I would have thought that using the Object's "on created" event and doing the collision check in there would have worked, as I assume when that event fires then you are guaranteed that the sprite exists. However, when I did a test, it only partially worked. Perhaps it isn't guaranteed to be put in a family before the "on created" event fires?

  • Good info, thanks. I'll see if I can change things around to give the new instance a chance to appear before the check. Ill also look into families. Thank you!
