I'm trying to add a menu that shows when you load a world for the first time, how do I do that in 1.12?

Got the code to work.

GuiScreenEvent

Code example please?

I haven't used it before, but you know how to subscribe to and use events, yes? Your description isn't very precise, so it's a bit hard to give specific advice. GuiScreenEvent has several sub-types that can be used in various situations.

 

If you're looking to display a menu when the player clicks Create New World, for example, it looks like subscribing to ActionPerformedEvent might work best. Get the list of buttons and swap out the Create New World button for a custom button that you create to load your new menu.

I'm wanting a GUI to show when the user enters a world for the first time and not when they click "Create New World".

When every player enters the world for the first time? Or only for the first player to ever enter the world?

When every player joins the world for the first time.

Create a capability that simply stores a boolean of hasConnected or whatever and in the EntityJoinWorldEvent check that capability and if it is false then open a gui via EntityPlayer#openGui

Also, the World class has a getTotalWorldTime() method.

 

So basically you need to handle an appropriate event like when player joins world or similar, then post a GuiScreen using the information from getTotalWorlTime(). There are already tutorials for handling events and tutorials for creating GUIs, so try what you can and if you're still having trouble post your code.

@SubscribeEvent
public static void hasConnected(PlayerEvent.PlayerLoggedInEvent event) {
	INewtypeCapability nt = CapabilityUtils.getCapability(event.player,MAX_NEWTYPE_CAPABILITY,DEFAULT_FACING);
	if(!nt.hasShownHumantypeMenu()) {
		event.player.openGui(GundamMod.instance,HumantypeGUI.GUI_ID,event.player.getEntityWorld(),event.player.getPosition().getX(),event.player.getPosition().getY(),event.player.getPosition().getZ());
	}
}

This snippet is the code that should open the ui but it doesn't work. Loggin works so that means the function is being called.

Ok, I got it to work. I figured it out and now I just need to program the UI.
