public class EntityDeliveryMan extends EntityWorker{

	public EntityDeliveryMan(World worldIn) {
		super(worldIn);
		this.profession = EntityTyp.DELIVERY_MAN;
		this.Name = "Delivery Guy";
	}

	@Override
	public void onUpdate() {
		super.onUpdate();
		
	}
	
	@Override
	@SideOnly(Side.CLIENT)
	public EnumActionResult applyPlayerInteraction(EntityPlayer player,	Vec3d vec, @Nullable ItemStack stack, EnumHand hand) {
		return super.applyPlayerInteraction(player, vec, stack, hand);
	}
}

 

 

The base class.

            this.numTextures = numTextures;
        }
        
    }
}

 

 

This is the output after spawn.

When i change the custom name over a gui then, only the server get's it, but the client not.

How do i sync the client to the server data?

The ouput after changing the name.

Client still keeps the old data.

At first, I was going to say that it could just be that you're never calling setCustomNameTag() after the Name is changed, but seeing that you're printing the value of Name to the console and it's not changing, I guess that doesn't really solve the issue here, though you still may want to consider doing so.

 

I believe the real issue here is the way you're handling the GUI. The solution to the problem is not to sync the data from the client to the server. When working with GUIs, you want to use both sides, so your method that opens the GUI should not be @SideOnly(Side.CLIENT) and you should not use  Minecraft.getMinecraft().displayGuiScreen(), but instead FMLNetworkHandler.openGui().  I haven't worked with GUIs in a while, but here's a tutorial on using them properly:

- Just because things are the way they are doesn't mean they can't be the way you want them to be. Unless they're aspen trees. You can tell they're aspens 'cause the way they are.

I did. I call this function in the entity class

Spoiler

    public void setName(String Name)
    {
    	this.Name = Name;
    	this.setCustomNameTag(this.Name);
    	
    }

 

And the call in the gui

Spoiler

	@Override
	protected void keyTyped(char typedChar, int keyCode) throws IOException {
		workerName.textboxKeyTyped(typedChar, keyCode);
		worker.setName(workerName.getText());
		super.keyTyped(typedChar, keyCode);
	}

 

 

Changing the gui handling to gui handler will also not solve the problem.
