Unity Component Skills

BATCH-FIRST: Use *_batch skills when operating on 2+ objects to reduce API calls from N to 1.

Guardrails

Mode: Full-Auto required

DO NOT (common hallucinations):

• component_create / component_get do not exist → use component_add (add) and component_get_properties (read)
• component_find does not exist → use component_list to list components on an object
• componentType is case-sensitive — Rigidbody not rigidbody, BoxCollider not boxcollider
• Custom scripts need exact class name; if namespaced, use Namespace.ClassName

Routing:

• To create a C# component script → use script module's script_create first, then component_add
• To set multiple properties at once → use component_set_property_batch
• To enable/disable a component → component_set_enabled (not component_set_property)

Object Targeting: All single-object skills accept name (string), instanceId (int, preferred), and path (string, hierarchy path). Provide at least one.

Skills Overview

Other Skills (no batch):

• component_list - List all components on an object
• component_get_properties - Get component property values
• component_set_enabled - Enable/disable a component (Behaviour, Renderer, Collider)
• component_copy - Copy a component from one object to another

Single-Object Skills

component_add

Add a component to a GameObject.

*At least one identifier required

Returns: {success, gameObject, componentType, added}

component_remove

Remove a component from a GameObject.

Returns: {success, gameObject, componentType, removed}

component_list

List all components on a GameObject.

Returns: {success, gameObject, instanceId, components: [string]}

component_set_property

Set a component property value.

Provide one of: value (basic types), referencePath/referenceName (scene objects), or assetPath (project assets).

value type examples:

# float / int / bool / string
call_skill("component_set_property", name="Obj", componentType="Rigidbody", propertyName="mass", value=2.5)
call_skill("component_set_property", name="Obj", componentType="Rigidbody", propertyName="useGravity", value=False)

# Vector3 (JSON object with x, y, z)
call_skill("component_set_property", name="Obj", componentType="Transform", propertyName="localPosition",
           value={"x": 1, "y": 2, "z": 3})

# Color (JSON object with r, g, b, a — values 0-1)
call_skill("component_set_property", name="Obj", componentType="Light", propertyName="color",
           value={"r": 1, "g": 0.5, "b": 0, "a": 1})

# Enum (use string name)
call_skill("component_set_property", name="Obj", componentType="Rigidbody", propertyName="interpolation",
           value="Interpolate")

Returns: {success, gameObject, componentType, property, oldValue, newValue}

component_get_properties

Get all properties of a component.

Returns: {success, gameObject, componentType, properties: {name: value}}

Batch Skills

component_add_batch

Add components to multiple objects.

Returns: {success, totalItems, successCount, failCount, results: [{success, gameObject, componentType, added}]}

unity_skills.call_skill("component_add_batch", items=[
    {"name": "Enemy1", "componentType": "Rigidbody"},
    {"name": "Enemy2", "componentType": "Rigidbody"},
    {"name": "Enemy3", "componentType": "Rigidbody"}
])

component_remove_batch

Remove components from multiple objects.

Returns: {success, totalItems, successCount, failCount, results: [{success, gameObject, componentType, removed}]}

unity_skills.call_skill("component_remove_batch", items=[
    {"instanceId": 12345, "componentType": "BoxCollider"},
    {"instanceId": 12346, "componentType": "BoxCollider"}
])

component_set_property_batch

Set properties on multiple objects.

Returns: {success, totalItems, successCount, failCount, results: [{success, gameObject, componentType, property, oldValue, newValue}]}

unity_skills.call_skill("component_set_property_batch", items=[
    {"name": "Enemy1", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0},
    {"name": "Enemy2", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0}
])

Common Component Types

Physics

Rendering

Audio

UI

Example: Efficient Physics Setup

import unity_skills

# BAD: 6 API calls
unity_skills.call_skill("component_add", name="Box1", componentType="Rigidbody")
unity_skills.call_skill("component_add", name="Box2", componentType="Rigidbody")
unity_skills.call_skill("component_add", name="Box3", componentType="Rigidbody")
unity_skills.call_skill("component_set_property", name="Box1", componentType="Rigidbody", propertyName="mass", value=2.0)
unity_skills.call_skill("component_set_property", name="Box2", componentType="Rigidbody", propertyName="mass", value=2.0)
unity_skills.call_skill("component_set_property", name="Box3", componentType="Rigidbody", propertyName="mass", value=2.0)

# GOOD: 2 API calls
unity_skills.call_skill("component_add_batch", items=[
    {"name": "Box1", "componentType": "Rigidbody"},
    {"name": "Box2", "componentType": "Rigidbody"},
    {"name": "Box3", "componentType": "Rigidbody"}
])
unity_skills.call_skill("component_set_property_batch", items=[
    {"name": "Box1", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0},
    {"name": "Box2", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0},
    {"name": "Box3", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0}
])

Best Practices

1. Add colliders before Rigidbody for physics
2. Use component_list to verify additions
3. Check property names with component_get_properties first
4. Some properties are read-only (will fail to set)
5. Use full type names for custom scripts (e.g., "MyNamespace.MyScript")

Additional Skills

component_copy

Copy a component from one GameObject to another.

*At least one source identifier and one target identifier required

Returns: { success, source, target, componentType }

component_set_enabled

Enable or disable a component (Behaviour, Renderer, Collider, etc.).

*At least one identifier required

Returns: { success, gameObject, componentType, enabled }
