MiSK [Addon - 1.14.1] (Discontinued)

Custom Merchant:

command /blob:
  trigger:
    set {_m} to a new merchant named "Trader"
    add (a new trade of (2 of gold ingot) and (stone) for (iron ingot named "bob")) to {_r::*}
    add (a new trade of (1 of gold ingot) and (air) for (gold ingot named "fred")) to {_r::*}
    add trades {_r::*} to merchant {_m}
    open merchant {_m} to player

Locking a chest:

on rightclick on chest:
    player's tool is stick
    cancel event
    lock clicked block with key "key name"
    broadcast "a chest was locked!"
# you can now open this chest ONLY if your tool is named "key name"! :D

Villager Trade Editing:

set {_e} to target entity
set {_r} to a new trade of stone and stick for slimeball
add trade {_r} to villager {_e}

Vehicles:

(ProtocolLib)
on vehicle steer:
  event-string is "SPACEBAR"
  push player's vehicle up at speed 10
# maybe don't try this, else you'll end up in space...
# this can be used to make controllable vehicles
# if you need help/examples, you can ask me :)

The plugin contains a MerchantUtils class.
You can use this to easily mess with CMOs and villagers, as well as using syntax that isn't publically available yet!

These are designed to simplify Bukkit methods. They will not change between versions (as Bukkit methods sometimes do).

Add this to the top of your skript:

import:
    com.moderocky.misk.utils.LootTableUtils
    com.moderocky.misk.utils.SkriptUtils
    com.moderocky.misk.utils.MerchantUtils

You can then use the following methods in your code:

set {variable} to LootTableUtils.newSeed()
# returns a Java Random

set {variable} to SkriptUtils.getItemStack({item-here})
# returns a real Bukkit itemstack

set {list} to MerchantUtils.tradeList()
set {list} to MerchantUtils.tradeList({recipes})
# returns a mutable Java List for MerchantRecipes
# the second allows you to add a pre-existing collection

set {recipe} to MerchantUtils.disableRecipe({recipe})
set {recipe} to MerchantUtils.enableRecipe({recipe})
MerchantUtils.disableRecipe(merchant, integer)
MerchantUtils.enableRecipe(merchant, integer)
# allows you to disable individual recipes from a merchant or from a villager/wandering trader

set {recipe} to MerchantUtils.getRecipe(merchant, integer)
# returns a recipe at an index. Indices go from 0+, like inventory slots

MerchantUtils.merchant()
MerchantUtils.merchant(name)
MerchantUtils.merchant(tradelist)
MerchantUtils.merchant(name, tradelist)
MerchantUtils.merchant(recipes[ ])
MerchantUtils.merchant(name, recipes[ ])
# Simple CMO creators for every situation
# The last two accept a collection. It's just to cover every possibility

MerchantUtils.openMerchant(player, merchant)
# Simple CMO creators for every situation

And our two favourites...

MerchantUtils.setResult(merchant, integer, itemstack)
MerchantUtils.recipeWithResult(merchantrecipe, itemstack)
# Bukkit doesn't allow this by default, it took me a while to work around!
# Remember that these take ITEMSTACKS. Use the getItemStack() method.

MerchantUtils.tradeCreator(itemstack, itemstack, itemstack)
# A LOT simpler than Bukkit's constructor. Also handles all the hard work for you.
# Bukkit doesn't allow this by default, it took me a while to work around!
# Remember that these take ITEMSTACKS. Use the getItemStack() method.
