Okay so I recently made a forum post on the Minecraftforum.net and they said a bunch of things then after like 2 days one said that I was trying to open the gui on a singleplayer world and I had to use a PacketHandler for that. Now my question is, I don't understand the tutorial on the wiki. And I really need help with this. Minecraftforum.net link: http://www.minecraftforum.net/topic/1674623-i-need-help-with-a-guihandler

Okay I've already got that part. But I want to open a gui on the open of a NEW world. So I tried the PlayerTracker but that didn't work :I

Okay, I got an error that said that it tried to open a GUI without being a network mod. Code

Tell me if I forgot any class or code

Should I remove the WHOLE of that or just a bit of it?

For some odd reason the getClientGuiElement in the GuiHandler wont be called. Do I need to setup something or shouldn't I use that?

use:

FMLNetworkHandler.openGui()

instead of:

player.openGui

 

then the methods in the gui handler will be called.

only getServerGuiElement is called now as before.
