I have a block with a Tile Entity that, using a Tile Entity Special Render, have some floating text above it. The text rendering works as well, however i need to reload the world to see them. Here's a video showing what i mean.

So what happen is this: i launch a command where i set the position of the block, the name and the cost. Name and cost are stored into the tile entity to being displayed as floating text. Then the block is placed but no text appear until i rejoin the world, then i can see the texts. What i want is that i see the texts as the block is placed, without rejoining the world. How can i do that?

This is the code of the Tile Entity

 
	package com.cf.entities;
	import javax.annotation.Nullable;
	import com.cf.faction.Territory;
import com.cf.utils.TerritoryUtils;
	import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.play.server.SPacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.ITickable;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentString;
	public class TileEntityBuyer extends TileEntity{
	    private String name;
    private int cost;
    
    public NBTTagCompound writeToNBT(NBTTagCompound compound)
    {
        super.writeToNBT(compound);
        compound.setString("name", this.name);
        compound.setInteger("cost", this.cost);
        return compound;
    }
    
    public void readFromNBT(NBTTagCompound compound)
    {
        super.readFromNBT(compound);
        this.setName(compound.getString("name"));
        this.setCost(compound.getInteger("cost"));
    }
    
    @Nullable
    public SPacketUpdateTileEntity getUpdatePacket()
    {
        return new SPacketUpdateTileEntity(this.pos, 7, this.getUpdateTag());
    }
    public NBTTagCompound getUpdateTag()
    {
        return this.writeToNBT(new NBTTagCompound());
    }
    
    public void setName(String n) {
        this.name = n;
    }
    
    public String getName() {
        return this.name;
    }
    
    public void setCost(int c) {
        this.cost = c;
    }
    
    public int getCost() {
        return this.cost;
    }
}

This is the code for the Rendering

 
	package com.cf.renderer;
	import javax.annotation.Nullable;
	import org.lwjgl.opengl.GL11;
	import com.cf.entities.TileEntityBuyer;
import com.cf.utils.Utils;

import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.TextComponentTranslation;
import net.minecraft.util.text.TextFormatting;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
	@SideOnly(Side.CLIENT)
public class TileEntityBuyerRenderer extends TileEntitySpecialRenderer<TileEntityBuyer> {
	    private RenderManager renderManager;
    
    public TileEntityBuyerRenderer(RenderManager r) {
        this.renderManager = r;
    }
    
    public void renderTileEntityAt(TileEntityBuyer te, double x, double y, double z, float partialTicks,
            int destroyStage) {
	        if (te.getName() != null && this.rendererDispatcher.cameraHitResult != null && te.getPos().equals(this.rendererDispatcher.cameraHitResult.getBlockPos()))
        {
            this.setLightmapDisabled(true);
            this.drawNameplate(te, Utils.getTranslation("block.buyer.click", TextFormatting.RED), x, y + 0.5D, z, 16);
            this.drawNameplate(te, Utils.getTranslation("block.buyer.name", TextFormatting.GREEN) + ": " + te.getName(), x, y + 0.25D, z, 16);
            this.drawNameplate(te, Utils.getTranslation("block.buyer.cost", TextFormatting.GOLD) + ": " + te.getCost() + "G", x, y, z, 16);
            this.setLightmapDisabled(false);
        }
    }
    public boolean isGlobalRenderer(TileEntityBuyer te) {
        return true;
    }
    
    
}

I do not know how you handle your command, but you might need to explicidly sync your tile with the client. It can be done by either using forge's custom packet system, or by manualy sending tile's update packet to a client. There is a World::notifyBlockUpdate method that is supposed to do that for you but I fould it to not be reliable enough for some reason.

Additionally looking at your tile's code I see that you are overriding

13 minutes ago, JimiIT92 said:

public SPacketUpdateTileEntity getUpdatePacket()

But not TileEntity::onDataPacket. When your update packet arrives on the client it calls that method. By default that method does nothing. You need to override it and read your data from the packet which is method's second argument.

Thank you, overriding that method like this

@Override
    public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity pkt) {
        this.setName(pkt.getNbtCompound().getString("name"));
        this.setCost(pkt.getNbtCompound().getInteger("cost"));
        super.onDataPacket(net, pkt);
    }

has solved the problem :)
