Difficulty: Beginner

Using a few basic tricks you can use MythicMobs to create highly versatile NPC's. The basic idea is to create a mob that has no AI/movement and doesn't despawn. We can then attach various mechanics and skills to our NPC mob such as messages, commands, or any skill you can think of.

Step 1 - Basic NPC

The first step is simply making your mob file, this can be anywhere, for this example we'll make a NPC subfolder.

Using the below mob as a base, we can make a simple NPC that just stands still. We are using LibsDisguises to make the mob look like a player.

plugins/MythicMobs/Mobs/NPC/Steve.yml

NPC_Steve:
  Type: INTERACTION
  Display: 'Steve the Guide'
  Disguise: Player <Inherit> setSkin Steve setDynamicName true
  Options:
    AlwaysShowName: true
    Despawn: persistent

• NPC_Steve This is what you'll use to spawn your NPC. /mm m spawn NPC_Steve
• Type: INTERACTION You can use whatever you like but we'll be using an interaction entity since it has no AI, no sound etc.
• Display: 'Steve the Guide' This is what will appear above your NPC's head.
• Disguise: Player <Inherit> setSkin Steve setDynamicName true This is what makes our NPC look like a player. You can replace "Steve" with whatever player's skin you'd like to use. You must keep the setDynamicName as true so the NPC can use the Display setting. The <Inherit> (case-sensitive) placeholder sets the NPC to show its Display: name. For more information about using custom skins read here.
• AlwaysShowName: true This makes the nameplate show above your NPC.
• Despawn: persistent This will keep your NPC spawned on reloads, restarts and chunk unloads.

Step 2 - Adding messages and commands

You can add messages or commands to your NPC using the Message and Command mechanics. For this guide we will be using @trigger and onInteract which will show the message or run the command for a user who right clicks the NPC. When you are testing make sure you're in SURVIVAL mode as creative mode players wont be targetable.

Message

This example will send a message to the player when they right click the NPC. We are adding the Universal Attribute cd=3 which will give it a cooldown of 3 seconds between clicks.

  Skills:
  - message{m=&bWelcome to Hypixel &a<trigger.name>&b!;cd=3} @trigger ~onInteract

Commands

This example will open a menu from DeluxeMenus for the player who right clicks the NPC.

  Skills:
  - command{c="dm open shops-blocks <trigger.name>"} @trigger ~onInteract

You can add as many skills or mechanics as you like to your NPC, not just messages and commands. You can run any mechanic and any metaskill.

Step 3 - ModelEngine (Optional)

If you want your NPC to use a ModelEngine model we can remove the disguise line and instead use 2 skills to apply a model to it. We will be using onSpawn and onLoad to make sure the model is always applied to the mob even after restarts.

You will also need to add a nametag bone to your models to display the name above them. You can do this by opening your model in Blockbench and creating an empty bone and calling it tag_name, then upload the newly edited model to your Blueprints folder and use /meg reload.

plugins/MythicMobs/Mobs/NPC/Steve.yml

NPC_Steve:
  Type: INTERACTION
  Display: 'Steve'
  Options:
    AlwaysShowName: true
    Collidable: false
    Despawn: persistent
  Skills:
  - model{m=SteveModel;n=name;save=true} @self ~onSpawn

With the model mechanic the attributes are

• m=SteveModel This is where the name of your model goes, for example we have plugins/ModelEngine/Blueprints/SteveModel.bbmodel
• n=name This is the name of our nametag bone we created.
• save=true Tells ModelEngine that the model should be preserved, even across restarts

Step 4 - Spawning the NPC

You can now use /mm reload to reload the modified files and add your NPC into the server. Simply stand where you want the NPC to be and use /mm m spawn NPC_Steve.

You now have a NPC created by MythicMobs.
