Here's an example of Mod Menu's translations into Pirate Speak. To create your own, simply replace modmenu at the end (NOT the one in the beginning) of the translation key with your own mod ID, for example modmenu.descriptionTranslation.traverse.

en_pt.json

"modmenu.nameTranslation.modmenu": "Menu o' mods!",
"modmenu.descriptionTranslation.modmenu": "Menu o' mods ye installed matey!",
"modmenu.summaryTranslation.modmenu": "Menu o' mods ye installed matey!"

The summary translation is redundant here and does not need to be included because it's the same as the description, but it was included to show that you may translate the summary (a short, one-sentence description of the mod) separately from the description, even in English!

Badges ("badges": [ ])

While the Client badge is added automatically to mods set as client-side only (set "environment": "client" in fabric.mod.json to do this.), other badges such as the Library and Deprecated badges require definition here.

Supported values:

• library - should be assigned to mods that are purely dependencies for other mods that should not be shown to the user by default unless they toggle them on.
• deprecated - should be assigned to mods that exist purely for legacy reasons, such as an old API module or such.

Any others will be ignored, and Mod Menu does not support adding your own badges. You may open an issue here if you have a compelling use case for a new badge.

Links ("links": { })

The links object allows mod authors to add custom hyperlinks to the end of their description. If you specify a sources contact in the official fabric.mod.json metadata, it will also be included in the links section.

Any key in the links object will be included in the links section, with the key being used as a translation key. For example, this:

fabric.mod.json

"custom": {
    "modmenu": {
        "links": {
          "modmenu.discord": "https://discord.gg/jEGF5fb"
        }
    }
}

will show as a link with the text "Discord", since "Discord" is the English translation of "modmenu.discord" provided by Mod Menu.

Mod Menu provides several default translations that can be used for links. A full list can be seen in Mod Menu's language file here. All default link translation keys take the form modmenu.<type>.

You can also provide your own translations if you would like to add custom links. Make sure to use your own namespace (as opposed to modmenu) for any custom keys.

Parents ("parent": "mod_id" or { })

Parents are used to display a mod as a child of another one. This is meant to be used for mods divided into different modules. The following element in a fabric.mod.json will define the mod as a child of the mod 'flamingo':

fabric.mod.json

"custom": {
    "modmenu": {
        "parent": "flamingo"
    }
}

However, if you want to group mods under a parent, but the parent isn't an actual mod, you can do that too. In the example below, a mod is defining metadata for a parent. Make sure that this metadata is included in all of the children that use the fake/dummy parent. This can also be used as a fallback for an optional parent, it will be replace by the mod's real metadata if present.

fabric.mod.json

"custom": {
    "modmenu": {
        "parent": {
            "id": "this-mod-isnt-real",
            "name": "Fake Mod",
            "description": "Do cool stuff with this fake mod",
            "icon": "assets/real-mod/fake-mod-icon.png",
            "badges": [ "library" ]
        }
    }
}

Dummy parent mods only support the following metadata:

• id (String)
• name (String)
• description (String)
• icon (String)
• badges (Array of Strings)

Disable update checker ("update_checker": false)

By default, Mod Menu's update checker will use the hash of your mod's jar to lookup the latest version on Modrinth. If it finds a matching project, it will check for the latest version that supports your mod loader and Minecraft version, and if it has a different hash from your existing file, it will prompt the user that there is an update available.

You can disable the update checker by setting update_checker to false in your Mod Menu metadata like so:

fabric.mod.json

"custom": {
    "modmenu": {
        "update_checker": false
    }
}

Getting Started

To use the API, implement the ModMenuApi interface on a class and add that as an entry point of type "modmenu" in your fabric.mod.json like this:

fabric.mod.json

"entrypoints": {
  "modmenu": [ "com.example.mod.ExampleModMenuApiImpl" ]
}

Mod Config Screens

Mods can provide a Screen factory to provide a custom config screen to open with the config button. Implement the getModConfigScreenFactory method in your API implementation to do this.

The intended use case for this is for mods to provide their own config screens. The mod id of the config screen is automagically determined by the source mod container that the entrypoint originated from.

Provided Config Screens

Mods can provide Screen factories to provide a custom config screens to open with the config buttons for other mods as well. Implement the getProvidedConfigScreenFactories method in your API implementation for this.

The intended use case for this is for a mod like Cloth Config to provide config screens for mods that use its API.

Modpack Badges

Mods can give other mods the Modpack badge by implementing the attachModpackBadges method, such as through the following:

@Override
public void attachModpackBadges(Consumer<String> consumer) {
	consumer.accept("modmenu"); // Indicates that 'modmenu' is part of the modpack
}

Note that 'internal' mods such as Minecraft itself and the mod loader cannot be given the modpack badge, as they are not distributed within a typical modpack.

Static Helper Methods

ModMenuApi also offers a few helper methods for mods that want to work with Mod Menu better, like making their own Mods buttons.

Creating a Mods screen instance

You can call this method to get an instance of the Mods screen:

Screen createModsScreen(Screen previous)

Creating a Mods button Text

You can call this method to get the Text that would be displayed on a Mod Menu Mods button:

Text createModsButtonText()
