every frame, I store the position in a list of vectors, so the list will have all of the positions when the player dies, then it creates a “ghost” player that just sets its position to the corresponding place in the list throughout time.
Basically, it stores the positions in a list, then a ghost player receives that list and sets its position to the opposite of where it was in the first one so it goes backwards.
sorry that was not a compact explanation :)
Tell me if you need me to explain it better haha
