ScriptingHUD

hud.add('beds', 'Bed Alert', function () {
    return ['§bbeds §f' + count, '§7closest §f' + nearest + 'm'];
});

That is the whole API. Position, anchoring, the backing panel, the fade, drag-and-drop placement in /bitchos hud and persistence in hud.json all come from the host.

• Return an array of lines, a single string, or nothing. Nothing (or an empty array) means "no readout right now" and the element fades out. That is how it should behave in a lobby.
• The supplier is called once per frame. Compute on tick and format here; lobby-threat.js shows the pattern.
• Ids are namespaced with your script's name, so two scripts can both use 'main'.
• hud.remove('beds'), hud.list().
• Everything a script registers is removed when it reloads or unloads.

var lines = [];

function onTick() {
    var t = bitchos.threat.lobby();
    lines = t < 0 ? [] : ['§bthreat §f' + t, '§7' + bitchos.threat.describe(t)];
}

function onLoad() {
    hud.add('main', 'Lobby threat', function () { return lines; });
}
