First off, lemme explain what i'm trying to do. You know in half-life games where the main menu is just a loaded map? That but in MC.

 

I've got an instance of the local server running, but my problem is that I can't get the client to visually connect.

I get this:

2013-07-29 21:56:58 [iNFO] [sTDOUT] loading single player
2013-07-29 21:56:58 [iNFO] [Minecraft-Server] Player593[/127.0.0.1:0] logged in with entity id 158 at (73.4211304951156, 67.0, -199.52293203796467)
2013-07-29 21:56:58 [iNFO] [Minecraft-Server] Player593 joined the game

 

but after that I'm stuck on the main menu. Nothing changes. How do I force MC to switch to the ingame view?

 

I've tried setting the GUI, but that's it; when MC runs the integrated server he DOES automagically pop into the game but I can't figure out how to replicate that.

 

 

So you want to show what is on the world spawn in the main menu after the integrated server as started ?

 

Yeah, I'm trying to figure out how to get the player in game for the first part. Displaying a GUI's the easy part.

From the log, the player is logged in. Which means you can get his socket adress, the player entity instance...

You can use Minecraft.displayGuiScreen(instanceofyourguiclass), right ?

The player logs in,but visually I'm still on the main menu, I can't see a difference.

But you should have two screens. One is for the server holder and one for the client.
