NOTE: This is a client-side mod only! Other players cannot see custom achievements. It is safe to use on other servers.
✨ Features:
- A steam-like gui overlay with informative draggable widgets, achievement progression system and custom animated popups
- Custom achievement support for Mod Creators!
- Advancements have been rebranded to "Achievements".
- Use /achievement grant/revoke for vanilla achievements or /customachievement grant/revoke for custom achievements!
⚙️ Adding Custom Achievements (for developers):
Add your own achievements by dropping a simple JSON file into your resource pack or mod!
Example json:
{
"title": "Welcome!",
"description": "Joined the game for the first time",
"icon": "mymod:textures/achievement/first_login.png",
"maxProgress": 1,
"hidden": false,
"rare": false
}
Place it at assets//achievements/.json, then trigger it from code with
AchievementTrigger.grant("id", 1)
or grant it yourself with /customachievement grant .
For progress-based achievements (e.g. "kill 10 zombies"), set maxProgress higher and call grant(id, amount) each time — it only unlocks once progress reaches maxProgress.
