Unity Animator Skills

Control Unity's Mecanim system — create Animator Controllers, add layers' states / transitions / parameters, assign controllers to GameObjects, set parameters at runtime, and play states.

Operating Mode

• Approval：查询类 skill（animator_get_parameters / animator_get_info / animator_list_states，源码标 SkillMode.SemiAuto）直接执行；其余变更类（create_controller / add_parameter / set_parameter / play / assign_controller / add_state / add_transition，标 SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。
• Auto / Bypass：所有 skill 直接执行；Auto 走 AI 自我评估，Bypass 全放行。
• 本模块不含 Delete / PlayMode / Reload / 高危 skill，无 Bypass-only 拦截项。
• animator_set_parameter / animator_play 作用于场景中已挂 Animator 的 GameObject；如果当前不在 Play mode，状态机只在 Editor 预览模式推进，效果与 runtime 不完全等价。

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

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

Returns: {controller, layer, layerName, stateCount, states: [{name, tag, speed, hasMotion}]}

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.

Example: Complete Animation Setup

import unity_skills

# 1. Create controller
unity_skills.call_skill("animator_create_controller",
    name="PlayerController",
    folder="Assets/Animations"
)

# 2. Add parameters
unity_skills.call_skill("animator_add_parameter",
    controllerPath="Assets/Animations/PlayerController.controller",
    paramName="Speed", paramType="float", defaultFloat=0
)
unity_skills.call_skill("animator_add_parameter",
    controllerPath="Assets/Animations/PlayerController.controller",
    paramName="IsGrounded", paramType="bool", defaultBool=True
)
unity_skills.call_skill("animator_add_parameter",
    controllerPath="Assets/Animations/PlayerController.controller",
    paramName="Jump", paramType="trigger"
)

# 3. Assign to character
unity_skills.call_skill("animator_assign_controller",
    name="Player",
    controllerPath="Assets/Animations/PlayerController.controller"
)

# 4. Control at runtime
unity_skills.call_skill("animator_set_parameter",
    name="Player", paramName="Speed", paramType="float", floatValue=5.0
)

# Trigger jump
unity_skills.call_skill("animator_set_parameter",
    name="Player", paramName="Jump", paramType="trigger"
)

# Play specific state
unity_skills.call_skill("animator_play", name="Player", stateName="Idle")

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
