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