tilemap-box-fill	Fill a rectangular region of a Tilemap with a single TileBase asset using Tilemap.BoxFill. The region is defined by an inclusive min and max cell coordinate.	generated-by mcp-plugin-dotnet

Tilemap / Box Fill

Fill a rectangular block of cells of a Tilemap with one tile via Tilemap.BoxFill.

Inputs

• gameObjectRef — the GameObject hosting the Tilemap (required).
• minX, minY — inclusive minimum cell coordinate.
• maxX, maxY — inclusive maximum cell coordinate.
• z — cell Z coordinate (default 0).
• tileAssetPath — Assets/-rooted path to the TileBase asset to fill with (required).

Behavior

Loads the tile, calls Tilemap.BoxFill(start, tile, minX, minY, maxX, maxY), marks the scene dirty, and repaints. Returns the filled cell count. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool tilemap-box-fill --input '{
  "gameObjectRef": "string_value",
  "tileAssetPath": "string_value",
  "minX": 0,
  "minY": 0,
  "maxX": 0,
  "maxY": 0,
  "z": 0
}'

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

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool tilemap-box-fill --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

minX	integer	Yes	Inclusive minimum cell X coordinate.
minY	integer	Yes	Inclusive minimum cell Y coordinate.
maxX	integer	Yes	Inclusive maximum cell X coordinate.
maxY	integer	Yes	Inclusive maximum cell Y coordinate.
z	integer	No	Cell Z coordinate (default 0).
