Hello,

I want to get the raw name of a player rendered in the player list, but when I use getUnformattedComponentText(), the game crash.

Here is my code :

package com.example.examplemod;

import java.util.List;

import javax.annotation.Nullable;

import com.mojang.authlib.GameProfile;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.Gui;
import net.minecraft.client.gui.GuiIngame;
import net.minecraft.client.gui.GuiPlayerTabOverlay;
import net.minecraft.client.network.NetHandlerPlayClient;
import net.minecraft.client.network.NetworkPlayerInfo;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.EnumPlayerModelParts;
import net.minecraft.scoreboard.IScoreCriteria;
import net.minecraft.scoreboard.ScoreObjective;
import net.minecraft.scoreboard.ScorePlayerTeam;
import net.minecraft.scoreboard.Scoreboard;
import net.minecraft.util.text.TextComponentString;
import net.minecraft.util.text.TextFormatting;
import net.minecraft.world.GameType;
import net.minecraftforge.fml.relauncher.ReflectionHelper;

public class TabOverlay extends GuiPlayerTabOverlay {

	String playerName = "";
	String name = "";
	
	public TabOverlay(Minecraft mcIn, GuiIngame guiIngameIn) {
		super(mcIn, guiIngameIn);
	}
	
	ReflectionHelper ref;
	GuiPlayerTabOverlay gui;
	
	 /**
     * Returns the name that should be renderd for the player supplied
     */
	@Override
    public String getPlayerName(NetworkPlayerInfo networkPlayerInfoIn)
    {	
		
		playerName = networkPlayerInfoIn.getDisplayName() != null ? networkPlayerInfoIn.getDisplayName().getFormattedText() : ScorePlayerTeam.formatPlayerName(networkPlayerInfoIn.getPlayerTeam(), networkPlayerInfoIn.getGameProfile().getName());
		
		name = networkPlayerInfoIn.getDisplayName().getUnformattedComponentText(); // this is the line 48
		
		//Rest of code
		
    }
}

 

And here is the error in the log :

java.lang.NullPointerException: null

I don't understand why there is this error. Does someone know ?

Mistakes

The problem is that when you set playerName you check if getDisplayName() returns null. But when setting the name you don't check it, so if is null you are trying to get a property from a null object, wich of course will throw an error. I don't know what are you trying to do there but you have 2 options:
set name = playerName
do the null check, like you've done in playerName, for the name

Problem solved, I now use this to get the player name :

name = networkPlayerInfoIn.getGameProfile().getName();
