Im creating the totem of undying so i need to put the particles into an entity, but i dont know how, to use addParticles but dont work.

Look at ClientPacketListener.handleEntityEvent() for how vanilla does this.

Yes, but this only work in client side i need another player see it too

See the bottom of here for how to broadcast packets: https://forge.gemwire.uk/wiki/SimpleChannel

You probably want to use something like

PacketDistributor.TRACKING_ENTITY.with(() -> player);

 which sends the packet to all other players in range of that "player".

 

You will need to include the player.getId() in the packet you send.

So on the client side you can then use it to do Minecraft.getInstance().level.getEntity() - check this is not null

Okay, i think i understand but im getting issues, i create another packet to sync entity to another players like this

package com.naim.belloto.networking.packet;

import com.naim.belloto.networking.handler.ClientSyncHandler;
import net.minecraft.client.Minecraft;
import net.minecraft.network.FriendlyByteBuf;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.fml.DistExecutor;
import net.minecraftforge.network.NetworkEvent;

import java.util.Objects;
import java.util.function.Supplier;

public class ClientSyncPacket {

    public ClientSyncPacket() {

    }

    public ClientSyncPacket(FriendlyByteBuf buf) {

    }

    public void toBytes(FriendlyByteBuf buf) {

    }

    public boolean handle(Supplier<NetworkEvent.Context> ctx) {
        NetworkEvent.Context context = ctx.get();
        context.enqueueWork(() -> {

            assert Minecraft.getInstance().player != null;
            int idplayer = Minecraft.getInstance().player.getId();

            DistExecutor.unsafeCallWhenOn(Dist.CLIENT,() -> () -> ClientSyncHandler.handlePacket(ctx, idplayer));

        });
        return true;
    }
}

And in the handler:

public class ClientSyncHandler {

    public static boolean handlePacket(Supplier<NetworkEvent.Context> ctx, int idPlayer) {
        Minecraft.getInstance().level.getEntity(idPlayer);
        return true;
    }

        
}

But is not working :// 

Aah i though Minecraft.level.getIstance().getEntity(playerid) sincronice what is happen with player using getEntity() i was wrong.

So u said playerid is not the correct player? And how i get the correct player id?

Or im wrong too?

Sry if is a stupid question Minecraft is not difficult but im lerning

So i need 1 more packet to server side?

Okaay thx i fixed ^^
