The Animator Controller controls animation through layers with state machines, controlled by parameters.

| layers | The layers in the controller. |
| parameters | Parameters are used to communicate between scripting and the controller. They are used to drive transitions and blendtrees for example. |
| AnimatorController | Constructor. |
| AddEffectiveStateMachineBehaviour | Adds a state machine behaviour class of type stateMachineBehaviourType to the AnimatorState for layer layerIndex. This function should be used when you are dealing with synchronized layer and would like to add a state machine behaviour on a synchronized layer. C# Users can use a generic version. |
| AddLayer | Utility function to add a layer to the controller. |
| AddMotion | Utility function that creates a new state with the motion in it. |
| AddParameter | Utility function to add a parameter to the controller. |
| CreateBlendTreeInController | Creates a BlendTree in a new AnimatorState. |
| GetBehaviours | Returns all StateMachineBehaviour that match type T or are derived from T. |
| GetStateEffectiveBehaviours | Gets the effective state machine behaviour list for the AnimatorState. Behaviours are either stored in the AnimatorStateMachine or in the AnimatorLayer's ovverrides. Use this function to get Behaviour list that is effectively used. |
| GetStateEffectiveMotion | Gets the effective Motion for the AnimatorState. The Motion is either stored in the AnimatorStateMachine or in the AnimatorLayer's ovverrides. Use this function to get the Motion that is effectively used. |
| MakeUniqueLayerName | Creates a unique name for the layers. |
| MakeUniqueParameterName | Creates a unique name for the parameter. |
| RemoveLayer | Utility function to remove a layer from the controller. |
| RemoveParameter | Utility function to remove a parameter from the controller. |
| SetStateEffectiveBehaviours | Sets the effective state machine Behaviour list for the AnimatorState. The Behaviour list is either stored in the AnimatorStateMachine or in the AnimatorLayer's ovverrides. Use this function to set the Behaviour list that is effectively used. |
| SetStateEffectiveMotion | Sets the effective Motion for the AnimatorState. The Motion is either stored in the AnimatorStateMachine or in the AnimatorLayer's ovverrides. Use this function to set the Motion that is effectively used. |
| CreateAnimatorControllerAtPath | Creates an AnimatorController at the given path. |
| CreateAnimatorControllerAtPathWithClip | Creates an AnimatorController at the given path, and automatically create an AnimatorLayer with an AnimatorStateMachine that will add a State with the AnimationClip in it. |
| CreateStateMachineBehaviour | This function will create a StateMachineBehaviour instance based on the class define in this script. |
| FindStateMachineBehaviourContext | Use this function to retrieve the owner of this behaviour. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |
| animationClips | Retrieves all AnimationClip used by the controller. |
| GetInstanceID | Returns the instance id of the object. |
| ToString | Returns the name of the GameObject. |
| Destroy | Removes a gameobject, component or asset. |
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
| FindObjectOfType | Returns the first active loaded object of Type type. |
| FindObjectsOfType | Returns a list of all active loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| bool | Does the object exist? |
| operator != | Compares if two objects refer to a different object. |
| operator == | Compares two object references to see if they refer to the same object. |
