# Organize the character hierarchy

The main rule is: **CharacterBody and CharacterActor should always be in the root object (the "character" object).**

You can be creative with the rest of the components.

The demo characters use the following hierarchy:

| Root        | Contains ***CharacterBody*** and ***CharacterActor***                                               |
| Graphics    | Contains the **visual elements** of the character, from sprites to animated 3D meshes.              |
| States      | Contains the ***CharacterStateController*** and every ***CharacterState*** related to the character |
| Actions     | Contains the ***CharacterBrain*** and all the ***AIBehaviours*** (AI characters).                   |
| Environment | Contains the ***MaterialController*** (used by some of the states included in the Demo)             |
