SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires unity-mcp-cli.

What problem does it solve? Setting up the standard 2D tilemap hierarchy in Unity requires manually creating a Grid GameObject, adding a child Tilemap with a TilemapRenderer, and configuring cell sizes. This Skill automates that setup through the unity-mcp-cli so the scene is ready for tile painting in one command. ## Core Features & Use Cases - Automated Hierarchy Creation: Instantiates a Grid GameObject hosting a child GameObject with Tilemap and TilemapRenderer components. - Flexible Configuration: Optionally name the Grid and Tilemap, set the Grid cell size, and parent the Grid under an existing GameObject. - Structured Output: Returns GameObject and component references plus the tilemap instanceId for use in subsequent tile-painting operations. - Use Case: When starting a 2D level, invoke this Skill to create a Grid named "LevelGrid" with a custom cell size under a "World" parent, then immediately begin painting tiles on the returned tilemap reference. ## Quick Start Ask the AI to create a new tilemap grid in the active Unity scene with a custom grid name and cell size using the tilemap-create tool.

Frequently Asked Questions about tilemap-create

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a tilemap in Unity from the command line?▼

Run unity-mcp-cli run-tool tilemap-create with a JSON input specifying optional gridName, tilemapName, parentRef, and cellSize. The tool creates the Grid plus child Tilemap and TilemapRenderer in the active scene and returns their references.

How to set a custom cell size for a Unity Grid?▼

Pass a cellSize object with x, y, and z number fields in the input JSON, for example {"x": 0.5, "y": 0.5, "z": 0}. If omitted, the Grid defaults to a cell size of (1, 1, 0).

Can I parent a new tilemap Grid under an existing GameObject?▼

Yes, supply the parentRef parameter with a GameObject reference using its instanceID, hierarchy path, or name. The new Grid is parented under that GameObject when the reference is provided.

Why is unity-mcp-cli not found when running tilemap-create?▼

The CLI is not installed globally. Install it with npm install -g unity-mcp-cli or prefix commands with npx unity-mcp-cli, and check the unity-initial-setup skill for detailed installation steps.

What does the tilemap-create tool return after creation?▼

It returns references to the created Grid GameObject, Tilemap GameObject, Tilemap component, and TilemapRenderer component, plus the tilemap instanceId, names, and a success flag. These references can be used for follow-up tile painting operations.
