I thought hasKey would work, but apparently not. I have my code setup inside of a player tick handler, and it constantly spams "HI1" in the console.

 

public static void playerTick(EntityPlayer player)
{

	String playerName = player.username;
	NBTTagCompound worldNBT = player.worldObj.getWorldInfo().getNBTTagCompound();

	if(!worldNBT.hasKey(playerName + "Gold"))
	{

		GloriaRPG.print("HI1");

		worldNBT.setInteger(playerName + "Gold", 0);

	}

These values are only saved on the server. The console chat is sent from the client. what if you added !player.worldObj.isRemote to your if() statement? Would it stop then?

Nope. 

 

Also tried surrounding the if() with another one with the !world.isRemote.

Hi

 

I had a quick look into getNBTTagCompound, which calls updateTagCompound, and it looks to me like it creates it a new one each time and fills it with values stored in WorldInfo.  So you can add a key but it just gets thrown away at the end of your PlayerTick.

 

Why do you want to store something in WorldInfo?

Depending on what you want to do, .getAdditionalProperty and .setAdditionalProperty might be what you're looking for?
