# tile At Location Is Wall
Check if a tile at a location in the tilemap is also a wall tile.
```sig
tiles.tileAtLocationIsWall(null)
```
The tile in the tilemap at the location selected is checked to see if it is set as a wall. After they are placed in the tilemap with the Tilemap Editor, tiles can be set as _wall_ tiles.
## Parameters
* **location**: the [location](/reference/tiles/location) object for the tile to check if it's a wall.
## Returns
* a [boolean](/types/boolean) value that is `true` if the tile at **location** is a wall. The value is `false` if the tile is not a wall.
## Example #example
Set a tilemap with two columns of the same tile. Make one of the columns be all wall tiles. Send a ghost sprite across both colunms so it can detect which one is the wall.
```blocks
scene.onOverlapTile(SpriteKind.Player, assets.tile`myTile0`, function (sprite, location) {
if (tiles.tileAtLocationIsWall(location)) {
mySprite.sayText("That's a wall!")
} else {
mySprite.sayText("Not a wall.")
}
})
let mySprite: Sprite = null
scene.setBackgroundColor(11)
tiles.setCurrentTilemap(tilemap`level1`)
mySprite = sprites.create(img`
