JSON Menus

JSON Menus

A mod can add a menu without code. Put one file at:

Data/MenuHelper/Config/<ModName>/menu.json

The folder name is the mod name. Menu Helper reads these files once when the game starts.

Example

{
    "version": 1,
    "entries": [
        { "label": "MY MOD", "menus": ["main", "pause"], "insertBefore": "quit", "menu": "settings" }
    ],
    "menus": {
        "settings": {
            "kind": "items",
            "items": [
                { "type": "header", "label": "GENERAL" },
                { "type": "checkbox", "label": "SHOW MARKERS", "description": "Shows map markers.", "saveKey": "bShowMarkers", "default": true },
                { "type": "slider", "label": "RANGE", "saveKey": "fRange", "default": 50, "min": 0, "max": 100, "step": 5, "format": "{value} m" },
                { "type": "dropdown", "label": "MODE", "saveKey": "iMode", "default": 0, "options": ["A", "B"] },
                { "type": "hotkey", "label": "TOGGLE", "saveKey": "iToggleKey", "default": 0, "modifiers": true, "action": "toggle" },
                { "type": "color", "label": "TINT", "saveKey": "uTint", "default": "#FF00FF" },
                { "type": "button", "label": "ABOUT", "menu": "about" },
                { "type": "button", "label": "RESET STATS", "action": "resetStats", "papyrus": "MyMod_Script.OnMenuAction" }
            ]
        },
        "about": {
            "kind": "pages",
            "items": [
                { "type": "topic", "label": "ABOUT", "text": "<b>My Mod</b><br>Version 1.0", "image": "Textures/MyMod/logo.dds" }
            ]
        }
    }

examples/basic/Config/MenuHelperExample/menu.json in the repository uses every item type.

Entries

Field	Use
label	Required.
menus	"main", "pause" or both. Default: both.
insertBefore	Vanilla entry name in lower case (quit, settings, help, load, ...) or its number. Default: quit.

kind	"items" (default) or "pages".
items	List of items. Pages menus hold topic items only.

label	Required.

papyrus	Buttons and hotkeys: global Papyrus function to call, "Script.Function".

Actions

When a button or hotkey with action is pressed, Menu Helper:

• sends the Papyrus event MenuHelper_OnAction(string asModName, string asAction),
• calls plugins registered with RegisterActionListener,
• calls the papyrus function, if set. It must be Function Name(string asModName, string asAction) global. This only works in a loaded game.

Reading values

• Papyrus: MenuHelper.GetSavedFloat, GetSavedInt, GetSavedBool, GetSavedColor, and the event MenuHelper_OnSettingChange.
• Plugins: GetSavedValue and RegisterSettingListener.

Errors

A file with an unknown field or a bad value is skipped. The log names the file and the field.
