Tutorial: "Mob hijacker" item - pantonshire/Vulcan GitHub Wiki

NOTE: This tutorial was made for Vulcan Alpha 0.2.0 and is not guaranteed to work in other versions.

---

In this tutorial, I'll assume that you've already made an item. If you haven't, try this tutorial first.
This is a very fun item that allows you to ride whatever entity you want by just left-clicking it! Creeper? Sure! Wither Boss? No problem! And the best part is: you'll have made it yourself!

Setting up the file

• First, make a new Vulcan file.
• Set up a basic item like so:

type: item

attributes:
   set name to "Mob Hijacker"
   set description to "Left-click a mob to hijack it!"

Adding a hit_entity behaviour

• This should all look familiar. Now to start doing some new stuff. Below what you've written, add the following line:
  hit_entity:
• This line tells Vulcan that whatever code you write next, it should be run every time a mob is hit with the item.
• Below this, write:
  tell attacker to ride target
• This line will tell your player character to start riding whatever you hit with the item. It doesn't matter whether it's a pig, a zombie, or even the wither boss!
• By hitting the entity, we've been mean to it; we've taken some of its health away! Let's be generous and give it its health back.
• Write tell target to heal 1 health to give the mob its health back.

That's it! You just made a really cool item!

Finished code
Here's the completed code I wrote:

type: item

attributes:
    set name to "Mob Hijacker"
    set description to "Left-click a mob to hijack it!"
    set texture to "example_texture"

hit_entity:
    tell attacker to ride target
    tell target to heal 1 health
