# Bone Tags

> Special bone name prefixes that add behaviors: head tracking, hitboxes, nametags, shadows and mounts.

A bone tag is a **special prefix in a bone's name** that gives the bone a behavior. You set them in Blockbench, just by naming groups, and LodeEntities picks them up when the model loads. No config files involved.

## The tags at a glance

| Tag | On a bone named like | What it does |
| - | - | - |
| `h_` | `h_head` | The bone follows the base entity's **head rotation**. Your creature looks where it's looking. |
| `hi_` | `hi_head` | Same, but the bone **and all bones inside it** follow the head. |
| `b_`, `ob_` or the name `hitbox` | `b_body` | The bone defines a [custom hitbox](https://entities.lodemc.net/custom-hitboxes.md). |
| `p_` | `p_seat` | The bone is a **mount point**: a hitbox can be seated on it. |
| `tag_`, `ptag_`, `mtag_` | `tag_name` | The bone positions the [nametag](https://entities.lodemc.net/custom-nametags.md). |
| the name `shadow` | `shadow` | The bone defines the [custom shadow](https://entities.lodemc.net/custom-shadows.md). |

## The one you'll use first: h\_

Most creatures need a head that tracks. Rename your head bone from `head` to `h_head`, re-import, and the model's head follows the entity's gaze, turning to face players, looking around as the AI does.

Use `hi_` instead when the head has children that should turn along with it, like ears, horns or a hat bone nested inside.

## Trying it out

Any tag change is just a model change: rename the bone in Blockbench, save the model over the old one in `Mobs/`, `/le reload`, and spawn a fresh mob to see it.

## Going deeper

Three tags are big enough to get their own pages:

* [Custom Hitboxes](https://entities.lodemc.net/custom-hitboxes.md): shape where your creature can be hit.
* [Custom Nametags](https://entities.lodemc.net/custom-nametags.md): put the floating name exactly where you want it.
* [Custom Shadows](https://entities.lodemc.net/custom-shadows.md): size the shadow to the creature.
