I made an Invisible Proximity detector without using the distance block, so you can use it with clones. Space == show where the trigger ring is / hide it red dots will turn green when they hit the trigger You can look inside (specifically at the costumes) to see how it did it
Made this for my game, Chance of Chaos, where i have the player as many shapes, but wanted to keep the hitbox the same so when the player switches it doesn't screw them over by expanding into an damage item. discovered it by complete accident.
