[1.12.2] Check if player is sneaking, but server-side

[Ookamix1]

Hi there,

I want to spawn lightnings if the player if sneaking. So far I have this class:

@Mod.EventBusSubscriber(Side.CLIENT)
public class FamilyEventHandler {
    @SubscribeEvent
    public static void sneakBoost(InputUpdateEvent event) {
        if (event.getMovementInput().sneak) {
            World world = event.getEntity().getEntityWorld();
            if(!world.isRemote){
                world.spawnEntity(new EntityLightningBolt(world, event.getEntity().posX, event.getEntity().posY, event.getEntity().posZ, true));
            }
        }
    }
}

However, world.isRemote is always true, because the InputUpdateEvent only works Client-side.

So I could either #1 send a packet to the server which then spawns the entity, or #2 have an event on the server which checks if the player is sneaking.

I didn't understand how to send packets yet, so does anyone knows an event to check if a player is sneaking server-side?

Entity#isSneaking.

Where should I put that command though?

Put it where you need it.

 

Hint:

Entity#isSneaking returns a boolean; true when the player is sneaking and false when the player is not.

But I don't know where to put. It needs to be run every single time the player is sneaking, and server-side.

So I basically need an endless event loop which runs on the server.

Do you know how that works?

However, checking 60 times a second for each player on the server if he's sneaking sounds pretty bad for the performance, isn't there a better way with events?
