Register listener to player/entity

No it wouldn't be costly as long as you do it right.

 

I assume you want to listen to multiple players? If so, and you are worried about performance, just add the player entityID's to an ArrayList.

 

Register onto the event bus with PlayerEvent(the most specific event for your use available), and do a if(playerList.contains(evt.entityLiving.entityID) ) first, and the performance loss should be negligible.

Well after reading back over this, I should point at that a HashSet has a much faster .contains lookup due to how the hash key lookup functions.

 

ArrayLists are superior if an ordered system is required, as well as sporting faster full list iterations, however the HashSet uses a hash lookup, which means it has much faster random access.

 

If you only need to check if your list contains the ID, then just address the entityID from the evt, use a HashSet.
