The EnderTeleport event is fired whenever an enderman or shulker teleport.
It is also fired whenever a player teleports using an enderpearl (it is possible that other mods fire this event as well.)

You will need to cast the event in the function header as this class:
crafttweaker.event.EnderTeleportEvent
You can, of course, also import the class before and use that name then.
