Introduction

“Stacking” is the process of mounting multiple entities on top of each other.

Using Locators and their Use Entity and On-Summon Function properties, you can stack multiple rigs to add dynamic parts to your model.

Tutorial

Let’s take an existing rig (body) and stack our head rig (head) on top of it.

1. Inside of your body rig, create a new Locator named head_locator. Position this Locator where you want the head to be mounted.

2. Open up head_locator’s config and configure the following properties:

   1. Enable Use Entity

   2. Set the Entity Type to minecraft:item_display

   3. Set On-Summon Function to

      function animated_java:head/summon {args:{}}
      ride @n[type=item_frame,tag=aj.head.root,distance=..0.01] mount @s

3. Save and export both rigs (see Your First Blueprint for export instructions).

4. In Minecraft, reload your Data Pack and Resource Pack.

5. Run the following command to summon your body rig.

   execute rotated 0 0 run function animated_java:body/summon {args: {}}

6. You should see the head rig mounted on top of the body rig.

From here, you can use your own commands to adjust the head rig’s rotation as needed.

Common Issues

• The head rig falls behind the body rig when moving.

  This commonly happens when mounting the body root entity on an entity, then moving that entity via Motion (or the entity moving itself).

  The only (known) way to keep this connection seemless is to use the tp command to move the rig.
