Unity UI Skills

Use this module for Unity UGUI / Canvas workflows. It is separate from UI Toolkit.

Batch-first: Prefer ui_create_batch when creating 2+ UI elements.

Guardrails

Mode: Full-Auto required

DO NOT (common hallucinations):

• ui_add_canvas does not exist -> use ui_create_canvas
• ui_create_label does not exist -> use ui_create_text
• ui_create_checkbox does not exist -> use ui_create_toggle
• ui_set_color does not exist -> use component_set_property on Image/Text, or the dedicated UI property skills when available
• Do not confuse UGUI (ui) with UI Toolkit (uitoolkit)

Routing:

• For UXML/USS/UIDocument -> use uitoolkit
• For XR-compatible world-space Canvas conversion -> use xr_setup_ui_canvas
• For text updates after creation -> use ui_set_text
• For layout and alignment -> use ui_layout_children, ui_align_selected, ui_distribute_selected

Create Skills

Query and Layout Skills

Property and Effect Skills

High-Frequency Defaults

Canvas and Parenting

• ui_create_canvas defaults to ScreenSpaceOverlay.
• Most create skills accept parent; if omitted, Unity will create under the active Canvas or scene root depending on the implementation context.
• For reusable menu groups, create the Canvas once, then create a Panel and put all child controls under that panel.

Common Create Parameters

Important:

• Most create skills do not take explicit x/y placement.
• Create first, then place/anchor with ui_set_rect, ui_set_anchor, or ui_layout_children.

Layout and Anchoring Rules

• ui_set_anchor is the fastest way to move a control into a standard layout position.
• ui_set_rect is better for precise size/offset edits after anchoring.
• ui_layout_children is preferred over hand-positioning every child when building vertical, horizontal, or grid menus.

Anchor presets commonly used in production:

• MiddleCenter for modal/menu panels
• TopLeft or TopRight for HUD corners
• StretchAll for full-screen backgrounds

TextMeshPro Note

Text creation auto-detects TMP:

• TMP available -> TextMeshProUGUI
• TMP unavailable -> legacy Text

Read the response payload if you need to know which one was created before later component-specific edits.

Workflow Notes

1. Create a Canvas first.
2. Use panels to group related controls.
3. Prefer ui_create_batch for menus, HUD groups, and repeated widgets.
4. Use anchors and layout groups before hand-placing every child.
5. Text creation auto-detects TextMeshPro. Responses indicate whether TMP was used.
6. For world-space gameplay UI, build the Canvas here first, then convert for XR only if needed.
7. ui_create_batch is mainly for bulk creation, not precise positioning. Follow it with layout or rect/anchor adjustments.
8. ui_create_batch.items is a JSON string parameter in the current REST/API layer, not a raw array object.

Minimal Example

import unity_skills
import json

unity_skills.call_skill("ui_create_canvas", name="MainMenu")
unity_skills.call_skill("ui_create_panel", name="MenuPanel", parent="MainMenu", a=0.7)
unity_skills.call_skill("ui_set_rect", name="MenuPanel", width=320, height=240)
unity_skills.call_skill("ui_create_batch", items=json.dumps([
    {"type": "Button", "name": "StartBtn", "parent": "MenuPanel", "text": "开始", "width": 220, "height": 44},
    {"type": "Button", "name": "OptionsBtn", "parent": "MenuPanel", "text": "设置", "width": 220, "height": 44},
    {"type": "Button", "name": "QuitBtn", "parent": "MenuPanel", "text": "退出", "width": 220, "height": 44}
]))

unity_skills.call_skill("ui_set_anchor", name="MenuPanel", preset="MiddleCenter")
unity_skills.call_skill("ui_layout_children", name="MenuPanel", layoutType="Vertical", spacing=12)
