I know this has been suggested before, but I'd like a way to make an options screen for my mod. Something like Options > Mod options > mod name. I made a rough implementation attached below. (It doesn't scroll if there's enough mods that use it)

 

It requires a tweak to GuiOptions (Unless there's some other way of doing it)

 

In initGui():

this.buttonList.add(new GuiButton(9001, this.width/2-155+160, this.height / 6 -12 + 24*3, 150, 20, "Mod options"));

 

In actionPerformed()

if (par1GuiButton.id == 9001)
            {
                this.mc.gameSettings.saveOptions();
                GuiModOptions.getInstance().parentScreen = this;
                this.mc.displayGuiScreen(GuiModOptions.getInstance());
            }

 

A mod can register an options page like this:

GuiModOptions.addOptionPage("Button title", guiScreenWithParentSubclass);

 

Screenshots here

 

Since attachments aren't working:

GuiModOptions

GuiScreenWithParent

That would be a good idea, but it might get a little annoying to work with, assuming that nobody makes a base for the Mod Option GUI pages. I could get to work on that right now, actually.

 

EDIT: I just realized that that might also require config updating, which I'm not good with...

As usual, if you have stuff/patches you'd like to contribute to Forge, PR it.

Finalized the code and created a pull request on github.
