tilemap-create	Create a Grid GameObject with a child Tilemap + TilemapRenderer in the active scene. Optionally parent the Grid under an existing GameObject and name the tilemap. Returns the new tilemap GameObject reference and its instanceId.	generated-by mcp-plugin-dotnet

Tilemap / Create Grid + Tilemap

Create the standard 2D tilemap hierarchy: a Grid GameObject hosting a child GameObject with a Tilemap and TilemapRenderer. This is the minimal structure required before painting tiles.

Inputs

• gridName — optional name for the Grid GameObject (default Grid).
• tilemapName — optional name for the Tilemap child GameObject (default Tilemap).
• parentRef — optional GameObject to parent the new Grid under.
• cellSize — optional Grid cell size (default (1,1,0)).

Behavior

Creates the Grid + child Tilemap/TilemapRenderer, sets the cell size, parents under parentRef when supplied, marks the scene dirty, repaints, and returns references + the tilemap GameObject instanceId. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool tilemap-create --input '{
  "gridName": "string_value",
  "tilemapName": "string_value",
  "parentRef": "string_value",
  "cellSize": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool tilemap-create --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool tilemap-create --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name	Type	Required	Description
gridName	string	No	Name of the Grid GameObject.
tilemapName	string	No	Name of the child Tilemap GameObject.
parentRef	any	No	Optional GameObject to parent the new Grid under.
cellSize	any	No	Grid cell size. Defaults to (1,1,0).
