# Tilemap / Set Tile
|
|
|
|
Set the tile at a single cell of a `Tilemap`. The tile is loaded from an `Assets/`-rooted path to any `TileBase` asset (a `Tile`, `RuleTile`, etc.).
|
|
|
|
## Inputs
|
|
|
|
- `gameObjectRef` — the GameObject hosting the `Tilemap` (required).
|
|
- `x`, `y`, `z` — the integer cell coordinate (z defaults to 0).
|
|
- `tileAssetPath` — `Assets/`-rooted path to the `TileBase` asset; null/empty erases the cell.
|
|
|
|
## Behavior
|
|
|
|
Loads the tile asset (when supplied), calls `Tilemap.SetTile(cell, tile)`, marks the scene dirty, and repaints. Runs on the Unity main thread.
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool tilemap-set-tile --input '{
|
|
"gameObjectRef": "string_value",
|
|
"x": 0,
|
|
"y": 0,
|
|
"z": 0,
|
|
"tileAssetPath": "string_value"
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool tilemap-set-tile --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool tilemap-set-tile --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 |
|
|
|------|------|----------|-------------|
|
|
| `gameObjectRef` | `any` | Yes | Reference to the GameObject containing the Tilemap component. |
|
|
| `x` | `integer` | Yes | Cell X coordinate. |
|
|
| `y` | `integer` | Yes | Cell Y coordinate. |
|
|
| `z` | `integer` | No | Cell Z coordinate (default 0). |
|
|
| `tileAssetPath` | `string` | No | Assets/-rooted path to the TileBase asset to paint. Null/empty erases the cell. |
