LootJS: KubeJS Addon in FTB Skies 2

Same as in the All the Mods - Gravitas 4.0 guide

LootJS: KubeJS Addon is a tool for pack developers. It lets them modify the loot system with KubeJS. It doesn't add blocks or items for you to craft. Its job is to give pack makers a way to change what drops and where.^[1]

The mod needs KubeJS to run, and it's licensed under the GNU Lesser General Public License v3.0 only.^[1]

In this pack

The pack ships LootJS: KubeJS Addon 2.7.7, in the file lootjs-forge-1.18.2-2.7.7.jar. That's the Forge build for Minecraft 1.18.2.^[2]

Who it's for

If you just want to play, you don't need to do anything with this mod. It's aimed at people writing KubeJS scripts, such as pack makers or anyone customizing loot in their own copy of the pack.^[1]

Unverified The sources don't say which loot changes, if any, the pack makes with LootJS. They also don't show any quests or ATM Star path steps involving this mod, so its place in the pack's progression is unconfirmed.

LootJS: KubeJS Addon is a tool for pack developers, not something you play with directly. It lets a pack author change the loot system using KubeJS scripts.^[1]

The mod needs KubeJS to work. It is available for NeoForge, Forge and Fabric.^[1]

What to craft first

Nothing! The sources I have don't list any recipes that produce this mod's items, so there is no first item to make and no recipe block to show. There are no quests in this pack that involve it either.^[1]

Any loot changes you notice in this pack come from scripts written with the mod. You don't have to set anything up to benefit from them.^[1]

Unverified Which loot tables this pack actually changes, and how, is not confirmed by the available sources, so this guide doesn't list any specific loot changes.

Same as in the All the Mods - Gravitas 4.0 guide

LootJS: KubeJS Addon is a tool for pack developers rather than a content mod. It is a KubeJS addon for modifying the loot system, so it doesn't add machines, multiblocks, power, fluid or item handling for you to automate.^[1]

It runs on NeoForge, Forge or Fabric and needs KubeJS to work.^[1]

Unverified The sources I have don't explain how LootJS is used in this pack: which loot changes it makes, what its scripts do, or which config options exist. I have no config files, recipes or in-game descriptions for it, so I can't say what it changes in your world. Check the pack's KubeJS scripts if you want the details. This site does hold FTB Skies 2's own recipes, read from the pack itself: look the item up in the item browser.

FTB Skies 2 1.22.0 ships LootJS: KubeJS Addon 1.21.1-3.7.0. The mod was already in the pack by FTB Skies 2 1.0.1 or earlier. Here are the notable changes from the mod's own changelogs, newest first.^[3]

Mod changelog highlights

• 3.7.0 (the version in this pack): the replaceLoot action now accepts composite loot entries like alternatives, sequences and groups.^[3][4]
• 3.6.1: fixed addCondition not being visible for loot condition containers.^[5]
• 3.6.0: added ItemFilter.hasComponent(). Also added a replaceLoot variant that takes a filter, a loot entry, preserveCount and preserveComponentTypes, so you can keep certain component types when replacing loot.^[6]
• 3.4.3: fixed internal access to the private constructor of SetComponentsFunction.^[7]
• 3.4.2: refactored the different ItemFilters into their own classes.^[8]
• 3.4.0: added getPools, modifyPool, getPool, modifyPoolByName and getPoolByName to loot tables. Also added hasItem for pools and grouped loot entries.^[9]

If you write loot scripts, the 3.6.0 and 3.7.0 changes to replaceLoot are the ones you will notice most, and since the pack is on 3.7.0 you get both.^[3][4][6]

Unverified No pack changelog entries for LootJS were available, so changes between individual FTB Skies 2 releases are not covered here.
