Advancement JS
by westernat233
With Advancement JS, server owners can configure triggers and rewards for advancements through KubeJS scripts instead of editing datapacks by hand.
What it does
Advancement JS is a KubeJS addon for Minecraft Java Edition. It exposes a startup event, AdvJSEvents.trigger, where a script defines custom advancement triggers, and it adds custom rewards that scripts can attach to an advancement. The mod requires KubeJS, and Better Advancements is an optional dependency. Advancement JS runs on the client and the server, so both sides need it. Files are published for Fabric and Forge, and the latest file, 2001fabric-2.9.4 for 1.20.1 released on 2024-05-14, is the same build line on both loaders.
The mod is open source under the GNU Lesser General Public License v2.1 only, and its source code, issue tracker and wiki are public. Game versions with files are 1.18.2, 1.19.2 and 1.20.1. The mod was first published on 2023-12-28. Running the /advjs command generates built-in examples, which serve as a starting point for writing scripts.
Key features
Custom triggers in scripts
A script defined in the startup event can register a new trigger that advancements then reference.

The blockDestroyed trigger fires when a player breaks a block, and playerTouch fires when a player touches an entity.
Boss fight and kill triggers
The bossEvent trigger fires when a player joins a boss fight, and increasedKillScore fires when a player kills an entity.
Custom rewards
Scripts can define custom rewards that are granted when an advancement completes.
Built-in examples
The /advjs command generates example scripts that show how triggers and rewards are written.
