This is the closest thing to being invisible I can think of since we don’t have invisibits
This is probably closer related to a smokebomb
First make the player that can turn invisible have a special item I’m using bait. They can buy the item in a vending machine you can use whatever you want though. Make a box prop cover the entire map make it not showing at start then have an overlay button wired to a checker. To check for the bait( item ) then if check fails show prop make the prop vision to person. Then make a wire pulse block attached to all the box/boxes with a delay of whatever you want then wire it back to the boxes to hide them. Lastly you need to make a cooldown to the button attach a wire pulse block to another one and a overlay to hide the button T he first wire pulse block has a delay of .1 the other one has a delay of whatever you want then wire it to the overlay to show button you can completely remove the second one to make it a one time use.
