I have been using Minecraft.getMinecraft().displayGuiScreen(new Foo()); Which will not fire drawScreen() but it will fire initGui() (verified with breakpoints).

Code: https://gist.github.com/anonymous/262437fbb85368eb612b

Any ideas on why drawScreen() is not fired?

Client command which I know is run (break point triggered)

Minecraft.getMinecraft().displayGuiScreen(new GUIExperience());

You sure drawing is not called? (print?)

 

The only possibility I see is that you are immidiately closing gui after it's opened. Is there any line in your code that could set screen to null (and you forgot that)?

Yep, same results.

That should be impossible.

I am guessing that something is being thrown silently but I don't see anything in my logs (I also pushed my changes to the repo if you want to clone and poke at it).

Damn bro... Commands are ONLY fired on server. You can't fire client stuff on server thread. Not only it won't work, but also it will crash on dedicated server.

 

Either learn IGuiHandler or:

1. Open gui from client.

2. Send command, decide on server if player can open gui, send packet to player that opens gui.

 

Have a look at this post if you don't get how threads/sided-code works:

TL;DR is a client command not a server command and it works fine.

Ok, this is what's happening:

 

When you type a command in chat and press enter it first executes that command and then displays the "null" GuiScreen (meaning it closes anything that's there) in the assumption that that will close the chat window. But if the command opens a Gui...

 

How to fix? Wait a tick before opening the Gui.

You're a magician (sorted it thanks to you)!
