Get the used hand during AttackEntityEvent

[X-Lomir]

I know AttackEntityEvent fires 2 times, 1 for each hand. Is there a way to understand which hand the event is currently being fired for?

Attacks are always with the main hand.

I think you will find the event is called twice because it is called on both the client and the server.

You need to check 

event.getEntity().level.isClientSide

to make sure you are on the correct logical side for what you are trying to do.

In the end I was, by mistake, calling a method twice. I had already checked for the logical side, but the fact that the method was being called 2 times made me wonder. Thanks to your comment I realized my mistake, thanks!
