Hi, I am trying to make a mod which when you have loaded a world, it displays a message in the chat console saying if there is an update available.

 

I am using a method with the @ServerStarted annotation. The method contains a command saying to add a chat message when the world is loaded, however when I try to, Minecraft crashes and throws a NullPointerException at me.

 

I know that it is because the player doesn't exist yet, so it is currently null, so I am asking what is the proper method or annotation called when a world is loaded.

 

Here is my method where player is a reference to EntityPlayer

@ServerStarted
public void displayMessage(FMLServerStartedEvent event)
{
	player.addChatMessage("No new updates found");
}

 

Any help would be much appreciated.

Never mind, I figured out why Minecraft was throwing a NullPointerException at me, I was refrencing the player as a new object, which was set to null. So I just refrenced Minecraft and called an EntityPlayer message straight from here like this.

 

Minecraft mc = Minecraft.getMinecraft();

instead of

Minecraft mc = Minecraft.getMinecraft();
EntityPlayer player = mc.theplayer;

 

And when I needed to display a message in the chat, I went

mc.theplayer.addChatMessage("blahblahblah");

I guess you learn from your mistakes
