How do I install JStages?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does JStages work with?

The listing gives Minecraft 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This mod aims to add full KubeJS compatibility to the most used GameStages addons.

The mod currently supports:

I highly suggest using ProbeJS to see the syntax for each addon, or you can check the mod's source, however as a quick overview:

ItemStages functions can be accessed inboth client and server scripts with prefix ItemStages
ReDimensionStages functions can be accessed in server scripts with prefix DimensionStages

If you have any suggestions for other addons, let me know by creating an issue on github
