name	unity-animator
description	Use when users want to create animation controllers, add parameters, play animations, or control animation state machines.

Unity Animator Skills

Overview

Control Unity's animation system - create controllers, manage parameters, and control playback.

Common Mistakes

DO NOT (common hallucinations):

• animator_create_clip / animator_add_clip do not exist → AnimationClips are created via Unity Editor or asset import
• animator_set_speed does not exist → use component_set_property on Animator component with propertyName="speed"

Routing:

• For Timeline animation → use timeline module
• For component properties on Animator → use component module
• For animation import settings → use importer module

Skills

animator_create_controller

Create a new Animator Controller.

Parameter	Type	Required	Default	Description
name	string	Yes	-	Controller name
folder	string	No	"Assets/Animations"	Save folder

Returns: {success, name, path}

animator_add_parameter

Add a parameter to a controller.

Parameter	Type	Required	Default	Description
controllerPath	string	Yes	-	Controller asset path
paramName	string	Yes	-	Parameter name
paramType	string	Yes	-	float/int/bool/trigger
defaultFloat	float	No	0	Initial float value
defaultInt	int	No	0	Initial int value
defaultBool	bool	No	false	Initial bool value

animator_get_parameters

Get all parameters from a controller.

Parameter	Type	Required	Description
controllerPath	string	Yes	Controller asset path

Returns: {success, parameters: [{name, type, defaultFloat/defaultBool/...}]}

animator_set_parameter

Set a parameter value at runtime.

Parameter	Type	Required	Description
name	string	Yes	GameObject name
paramName	string	Yes	Parameter name
paramType	string	Yes	float/int/bool/trigger
floatValue	float	No*	Float value
intValue	int	No*	Integer value
boolValue	bool	No*	Boolean value

*Use the appropriate value for paramType (trigger doesn't need a value)

animator_play

Play a specific animation state.

Parameter	Type	Required	Default	Description
name	string	Yes	-	GameObject name
stateName	string	Yes	-	Animation state name
layer	int	No	0	Animator layer
normalizedTime	float	No	0	Start time (0-1)

animator_get_info

Get Animator component information.

Parameter	Type	Required	Description
name	string	Yes	GameObject name

Returns: {gameObject, instanceId, hasController, controllerPath, speed, applyRootMotion, updateMode, cullingMode, layerCount, parameterCount}

animator_assign_controller

Assign a controller to a GameObject.

Parameter	Type	Required	Description
name	string	Yes	GameObject name
controllerPath	string	Yes	Controller asset path

animator_list_states

List all states in a controller layer.

Parameter	Type	Required	Default	Description
controllerPath	string	Yes	-	Controller asset path
layer	int	No	0	Layer index

Returns: {success, states: [{name, tag, speed}]}

animator_add_state

Add a state to an Animator Controller layer.

Parameter	Type	Required	Default	Description
controllerPath	string	Yes	-	Controller asset path
stateName	string	Yes	-	Name for the new state
clipPath	string	No	null	Animation clip asset path to assign
layer	int	No	0	Layer index

Returns: {success, controller, stateName, layer}

animator_add_transition

Add a transition between two states in an Animator Controller.

Parameter	Type	Required	Default	Description
controllerPath	string	Yes	-	Controller asset path
fromState	string	Yes	-	Source state name
toState	string	Yes	-	Destination state name
layer	int	No	0	Layer index
hasExitTime	bool	No	true	Whether transition waits for exit time
duration	float	No	0.25	Transition duration in seconds

Returns: {success, from, to, layer, hasExitTime, duration}

Recipe Path

Recipe path rule: ../../recipes/animator/<command>.md

See ../../recipes/animator/README.md for the full command index.

Best Practices

1. Create controller before adding parameters
2. Use meaningful parameter names
3. Triggers reset automatically after firing
4. Set parameters before playing states
5. Use layers for independent animations (body + face)
6. States must exist in controller before playing
