Addon Recommendation


Available for LabyMod users with version greater than 3.6.5 (LabyMod 4 included)


With this packet the server can recommend published addons to the user and the user can install them very simple in a GUI. Multiple add-ons can be suggested at the same time or can also be flagged as being required. You have to react to the response of the client if an addon is required.

The checkbox "Do not ask again" is on the client side, you do not have to worry about it on the server side!


In LabyMod 4 the uuid key has been replaced with the namespace field due to technical changes - both in the server-side request and the client response.

Example code

public void recommendAddons() {
    JsonObject object = new JsonObject();
    JsonArray addons = new JsonArray();

    JsonObject addon = new JsonObject();
    addon.addProperty( "uuid", "3bd2a3c0-0309-47d4-a6f9-320b0e93bce1" ); // Published uuid of the addon
    addon.addProperty( "required", true ); // Required for this server?
    addons.add( addon );

    object.add( "addons", addons );

    // Send to LabyMod using the API
    LabyModProtocol.sendLabyModMessage( player, "addon_recommendation", object );


It only works with published addons! Here is the list of all available addons and their UUID: addons.json
