[1.11.2] Modyfing tile entity data from client gui & TESR rendering

[grand_gibus]

Hello everyone, 
I'd like to make a client gui that updates a tile entitie data, on server and client side, and for every player. How would I go about doing that?
I looked at the command block gui, it sends a packet to somewhere but I don't know what happens next.

 

Also, totally unrealted:

I made a TESR that renders stuff in a large area. The thing is, that if you look away from the tile entity block, the render disepears where I'd like to still be able to see the render. How could I fix that? The StructureBlock TESR has a field 

	    @Override
	    public boolean isGlobalRenderer(TileEntityStructure te)
	    {
	        return true;
	    }

,but I tried to integrate it and it didn't change anything, so yeah.

 

Thanks in advance!

To send data to the server you would have to create a custom packet (IMessage) along with a handler (IMessageHandler) and a NetworkWrapper for your mod using NetworkRegistry.INSTANCE.newSimpleChannel.

 

All it'd have to do is contain the relevant data (x,y,z) and on the handler get the tile entity at that location and update your data.

 

Hope this helps in some way

Thank you for the answer.

When I tried to make the gui and tile entity, I did a thing that sent a packet and updated the server tile entity. But it the problem seemed that the server wasnt updating the client tile entities

Override TileEntity::getRenderBoundingBox to return appropriate size of the rendered object.

If it's about rendering, you are not marking the TE as updated for rendering. I think you should call World#markAndNotifyBlock. (The flag parameter is explained on World#setBlockState)

[grand_gibus]

Thanks Abastro! It works for the TESR. 
For the TileEntity, where should I call the World#markAndNotifyBlock from? I've tried on both sides with no success.

It should work on either side, as it sends the update packet.

How and where did you call it?

Also how are you syncing the tileentity? Please post the relevant code.

Here is my code:

(TileEntity, IMessage, IMessageHandler, Client GUI)

public class TileEntityWorkBench extends TileEntity{

	private String schematicName = "";
	
	public TileEntityWorkBench(){
	}
	
	public void updateSchematicName(String name){
		this.schematicName = name;
	}
	
	public String getSchematicName(){
		return this.schematicName;
	}
	
    public void readFromNBT(NBTTagCompound compound)
    {
    	this.schematicName = compound.getString("schematicName");
        super.readFromNBT(compound);

    }

    public NBTTagCompound writeToNBT(NBTTagCompound compound)
    {
        NBTTagCompound nbt = super.writeToNBT(compound);
    	nbt.setString("schematicName", schematicName);
    	return nbt;
    }
    
    
    @Override
    public AxisAlignedBB getRenderBoundingBox(){
    	return INFINITE_EXTENT_AABB;
    }
    
}

public class ServerMessage implements IMessage {

	  public ServerMessage(){}

		  this.tag = tag;

	  }

	  @Override
	  public void toBytes(ByteBuf buf) {
		  buf.writeInt(messageType);

	  }

	  @Override

	  }

	  }
}

Sorry, didn't know what would be the most relevant code to show 

[Abastro]

So it's client->server update from the gui.

You need to implement tileentity syncing.

I think this post will cover your case.

You can manually read the data from the update packet with TileEntity#onDataPacket. Use it if you don't want readFromNBT to do the work. (e.g. update packet has a different format)

[grand_gibus]

Thank you Abastro!
It didn't really work out in the first place but then I messed a bit around and it ended up working by adding an onDataPacket() override . Here is my code if anyone from the future has this problem:

	@Override
    public void readFromNBT(NBTTagCompound compound)
    {
    	this.schematicName = compound.getString("schematicName");
        super.readFromNBT(compound);

    }

	@Override
    public NBTTagCompound writeToNBT(NBTTagCompound compound)
    {
        NBTTagCompound nbt = super.writeToNBT(compound);
    	nbt.setString("schematicName", schematicName);
    	return nbt;
    }    
@Override
    public NBTTagCompound getUpdateTag()
    {
        return this.writeToNBT(new NBTTagCompound());
    }
    
    @Nullable
    @Override
    public SPacketUpdateTileEntity getUpdatePacket()
    {
        return new SPacketUpdateTileEntity(this.getPos(), 1, this.getUpdateTag());
    }
    
    @Override
    public void onDataPacket(net.minecraft.network.NetworkManager net, net.minecraft.network.play.server.SPacketUpdateTileEntity pkt)
    {
    	this.readFromNBT(pkt.getNbtCompound());
    }

When the client the custom server packet handler recieve a message from the client gui, it executes this code:

	public static void updateWorkBenchInfo(ServerMessage message, WorldServer world){
		NBTTagCompound nbt = message.tag;
		TileEntityWorkBench workbench = (TileEntityWorkBench) world.getTileEntity(new BlockPos(nbt.getInteger("x"), nbt.getInteger("y"), nbt.getInteger("z")));
		workbench.updateSchematicName(nbt.getString("schematicname"));
		BlockPos pos = new BlockPos(nbt.getInteger("x"), nbt.getInteger("y"), nbt.getInteger("z"));
		world.markAndNotifyBlock(pos, null, world.getBlockState(pos), world.getBlockState(pos), 2);
		return;
	}
