To OP:
I suggest you tinker with player.zoom if you want to hide the player.
Just basically do something like set a player.attr to true if someone should go invisible then either in a System script or in a gani status script (like the "heart" gani that was on Maloria when it was public) make something that hides players with that attr set to true. Just player.zoom = 0; to hide and player.zoom = 1; to show. This will also hide their name.

Then there is also the easy way:
setani("", "");
