In my mod, I need to swap out the vanilla main menu (GuiMainMenu) for a custom main menu GUI that I wrote. I actually implemented this a couple of months ago using a solution I read about on the Minecraft Forums.

 

Basically, since Minecraft/FML/Forge does not post any kind of event (that I know of) when the GUI changes, I have a tick handler that checks to see if GuiMainMenu is being shown, and if it is, switches it with my custom menu. Here's the pertinent part of the TickHandler:

 

@Override
public void tickStart(EnumSet<TickType> type, Object... tickData) {
	Minecraft mc = Minecraft.getMinecraft();
	if(mc.currentScreen instanceof GuiMainMenu) {
		mc.displayGuiScreen(ClientProxy.mainMenu);
	}
}

 

This works almost perfectly, with the exception that the vanilla main menu shows up for a fraction of a second before the TickHandler realizes and swaps it out. When I wrote this a couple of months ago, I decided that it wasn't worth pursuing further at the time.

 

Obviously I could make this work seamlessly by editing base classes, but since the code controlling the display of the initial GuiMainMenu is in Minecraft.java...that would be a very bad idea if I wanted any compatibility at all with other mods.

 

Is my hack-ish solution with the TickHandler the best way to do this at the moment? I've seen other mods do stuff like this seamlessly, but none of them are open source.

 

If there isn't any better method, I might consider writing a PR to get some kind of Forge support for GUI substitution like this. Just curious what your thoughts are.
