Packets for TileEntities

Recommended Posts

This is a rather simple question. How would I send an update to all clients tracking (or clients 'associated' with) a TileEntity?

I know that with entities I can use

public static void sendToAllTracking(SimpleNetworkWrapper wrapper, Entity entity, IMessage message)
{
    if(entity.worldObj instanceof WorldServer)
    {
        ((WorldServer)entity.worldObj).getEntityTracker().func_151247_a(entity, wrapper.getPacketFrom(message));
    }
}

 

However, browsing through Vanilla code for TileEntities all I've found that would work is this:

public static void sendToAllTracking(SimpleNetworkWrapper wrapper, TileEntity tileEntity, IMessage message)
{
    if(entity.worldObj instanceof WorldServer)
    {
        ((WorldServer)entity.worldObj).getPlayerManager().getOrCreateChunkWatcher(tileEntity.xCoord, tileEntity.zCoord, false).sendToAllPlayersWatchingChunk(wrapper.getPacketFrom(message));
    }
}

 

However, those methods are private (and PlayerInstance is package private anyway), an reflection shouldn't be used for something as trivial as this.

 

Of course, I could just use SimpleNetworkWrapper#sendToAllAround(IMessage,TargetPoint) with a radius of 15 or 16 (and that's what I've been doing so far), but I would like to know if there is a 'proper' way to do this?

I'll help if I can. Apologies if I do something obviously stupid. :D

 

If you don't know basic Java yet, go and follow these tutorials.

What should this request contain? Would it just be changing the visibility of those methods, or would it have to be something more complex?

 

I have some spare time right now, I can go give it a try.

How does this look?

public List<net.minecraft.entity.player.EntityPlayer> playersWatchingChunk(int x, int y)
{
    PlayerInstance pi = getOrCreateChunkWatcher(x, y, false);
    return pi != null ? java.util.Collections.unmodifiableList(pi.playersWatchingChunk) : java.util.Collections.emptyList();
}
    
public void sendPacketToWatching(int x, int y, Packet packet)
{
    PlayerInstance pi = getOrCreateChunkWatcher(x, y, false);
    if(pi != null)
    {
        pi.sendToAllPlayersWatchingChunk(packet);
    }
}

    • Hi, I have the oficial launcher using the version 1.21, and forge 51.0.13, as soon as I start the installation the games crashes and gives me "exit code: 1", I haven't put any mods yet in the folder.
