Check if players on server are holding a specific item from client side?

[GMqwerty]

I want to check all players on a server if they are holding a specific item. I think I understand how to get the item they are holding, but I dont know from which event to check?

when exactly do you want to check this?

I want to run some code when a player holds a sword, so I guess I would have to check constantly? i dont know tho

you can use TickEvent.WorldTickEvent than get all players from the world via World#players
but note, TickEvents have two phases (START, END) choose one and they run on server and on client check this via TickEvent#side

Note that the client does not know about all players. This is something that should be done server side using LivingEquipmentChangeEvent so that you don't have to constantly check all players.

Why do you want to do this client side?

yea ik, i just want to check what items players near me hold, i am making a mod that shows you if someone is going to attack you, so if someone is holding a sword and is in a 10 block radius it shows you a message
