I am trying to modify player names on the tab list. I want this to be client side only. More specificaly, I would like the current player's name to be changed to whatever I want. I have tried many things but none have worked. I need this for 1.8.9.

 

  @SubscribeEvent(priority = EventPriority.LOWEST)
  public void onRenderGameOverlay(RenderGameOverlayEvent.Pre event) {
	  if (Minecraft.getMinecraft().thePlayer == null || Minecraft.getMinecraft().theWorld == null || event.type != RenderGameOverlayEvent.ElementType.PLAYER_LIST) {
		  return;
	  }
	  event.setCanceled(true);
	  renderTabList(event.resolution.getScaledWidth());
  }
  public void renderTabList(int width) {
	  Scoreboard scoreboard = Minecraft.getMinecraft().thePlayer.worldObj.getScoreboard();
	  
	  Minecraft.getMinecraft().ingameGUI.getTabList().renderPlayerlist(width, scoreboard, scoreboard.getObjectiveInDisplaySlot(0));
  }

 

I started writing this, which was copied from a scoreboard resize mod. I don't know if this is the right track.

 

	  @SubscribeEvent(priority = EventPriority.NORMAL)
	  public void onRenderGameOverlay(NameFormat event) {
		  
		  event.displayname = "test";
		  Minecraft.getMinecraft().thePlayer.refreshDisplayName();
	  }

 

I also tried this but realised it was only on multiplayer.

 

Thank you in advance.

I know 1.8.9 is not supported but I can figure it out from a newer solution.
