Skill Slots (Forge)

Source-provided project description. FreeMinecraftMods keeps creator credit and adds separate compatibility and decision guidance below.

Project overview

Skill Slots is a library mod that adds player skill slots for item-based skills, as a complementary to the hotbar. You can use KubeJS or Java code to create your own skills, or simply put an existing item in the slots and use a keybind to perform the right-clicking behavior. Example for adding a new skill using KubeJS: // priority: 0 // Server script // Make your item can be put in skill slots // If the item already has a right-click function, the skill already works now ServerEvents.tags('item', event => { event.add('skillslots:skill', 'minecraft:diamond') }) // Of course, you can use KubeJS to create an item, and add some fancy right-click function to it ItemEvents.rightClicked('minecraft:diamond', event => { event.player.tell('You right clicked a diamond!') // Cooldown, works event.player.addItemCooldown(event.item, 60) }) // This event will also be called when using the skill BlockEvents.rightClicked(event => { // Check the item cooldown by yourself event.player.tell('You right clicked a block!') }) // Here you will know how to get access to the skill slots from a player ItemEvents.rightClicked('minecraft:emerald', event => { let handler = Java.loadClass('snownee.skillslots.SkillSlotsHandler').of(event.player) let diamond = Item.of('minecraft:diamond') // Here are some NBT options to customize the skill diamond.nbt = diamond.nbt.SkillSlots = { UseDuration: 20, IconScale: 1.5, // CanBeToggled: true, // make your skill work as a passive skill. the player can toggle it on/off ChargeCompleteSound: 'minecraft:entity.player.levelup', // leave it empty to mute } // In config, you can disable the player ability to change skills // Here is an example to change the skill through KubeJS handler.setItem(0, diamond) // Example of checking if the player has a skill that can be toggled and currently activated let index = handler.findActivatedPassiveSkill(skill => skill.item.id === 'minecraft:diamond') if (index !== -1) { let skill = handler.skills.get(index) event.player.tell(skill.item.id) } }) You can use handler.setSlots(int) to set the amount of the unlocked slots, or use the Slot Unlock item provided by this mod. The colored button border is provided only when JEI is installed.

FreeMinecraftMods decision guide

This mod is most relevant to players looking for Miscellaneous, Adventure and RPG, Magic on Forge, NeoForge. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The latest stored update signal is Mar 8, 2025. Older projects can still work well, but they deserve extra compatibility testing before being added to a current world or public server.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
