Game Stages Conditions
Progression modpacks live and die by how well they pace their rewards. If a player can stumble into endgame gear during their first hour, the entire journey loses meaning. That is exactly the problem Game Stages Conditions solves. This lightweight add-on extends the popular Game Stages framework by introducing a condition predicate that data-driven files can read, letting you decide what loot spawns, which advancements fire, and how triggers behave based on the stage a player has reached.
In practice, that means a chest in a ruined portal can hand out modest supplies to a beginner while an end city treasure chest only reveals its best contents once the player has earned the appropriate stage. The mod does not add new items or blocks. Instead, it plugs directly into Minecraft's loot table and advancement systems, keeping your pack clean and your JSON files readable.
What Game Stages Conditions Actually Does
At its core, the add-on registers a condition type called gamestageconditions:stage. You drop this condition into any loot table entry, and the game checks whether the player opening that container currently holds the named stage. If they do, the entry rolls. If they do not, Minecraft simply skips it and moves to the next alternative.
The mod supports Minecraft 1.16 through 1.20 on both Forge and NeoForge, with Fabric builds available for several of those versions as well. Because it relies on vanilla data pack mechanics, it plays nicely with Lootr, which is strongly recommended if you run multiplayer servers where every player should see their own loot. Without Lootr, one player's stage can affect a shared chest for everyone.
Building a Stage-Gated Loot Table
A typical chest configuration uses the minecraft:alternatives entry type, which picks the first child whose conditions pass. Here is the structure in plain terms:
- A top-level pool with one roll.
- An alternatives entry containing several children.
- Each child is a loot table reference, such as minecraft:chests/end_city_treasure or minecraft:chests/ruined_portal.
- Each child carries a conditions array with the gamestageconditions:stage condition and a stage name like stage_2 or stage_1.
- A final child with no condition acts as the default fallback, so players without any stage still receive something.
That fallback matters more than most pack authors expect. If you forget it, players who have not yet been assigned a stage will open an empty chest and assume your pack is broken.
Triggers for Advancements and More
Since version 1.2, the add-on also ships with triggers that can be attached to advancements and similar data-driven content. Instead of only filtering loot, you can now fire advancement criteria when a player reaches a specific stage, which opens the door to custom quest lines, reward popups, and staged tutorials. Combined with the condition predicate, this turns Game Stages into a genuine progression engine rather than a simple gate.
If you would rather skip manual file wrangling, the foxygame.net launcher offers a one-click install path for Game Stages Conditions, pulling the correct build for your Minecraft version automatically and keeping it updated alongside your other add-ons.
How to Install Game Stages Conditions
Installation follows the standard mod workflow, and you should always confirm that Game Stages itself is present first, since this add-on depends on it.
- Install the correct loader for your Minecraft version, such as Forge, NeoForge, or Fabric.
- Place the Game Stages jar in your mods folder.
- Add the Game Stages Conditions jar beside it.
- Optionally add Lootr for per-player loot on servers.
- Launch the game once to generate config files, then edit your loot tables in a data pack.
When you download Game Stages Conditions, check the file name for the Minecraft version and loader tag, because a 1.18 Forge build will not run on 1.20 NeoForge. Pack authors who test on a single version often forget this and ship broken releases.
Practical Tips for Pack Authors
Keep your stage names consistent across loot tables, advancements, and scripts. A typo like stage1 instead of stage_1 fails silently, and the entry simply never triggers. Test each table by granting yourself stages with the Game Stages command and opening the container in a fresh world. Finally, document your stage order somewhere visible, because players will ask why a chest is empty long before they ask how the mod works.
Final Thoughts
Game Stages Conditions is a small utility with an outsized impact on pack design. It gives you precise control over when rewards appear, keeps your progression honest, and integrates cleanly with the tools you already use. Whether you are building a sprawling kitchen-sink pack or a tight story-driven experience, stage-gated loot tables are one of the simplest ways to make every milestone feel earned.
