# tile At Location Equals
Check if a location in the tilemap contains the tile you're looking for.
```sig
tiles.tileAtLocationEquals(tiles.getTileLocation(0, 0), null)
```
## Parameters
* **location**: a [location](/reference/scene/location) in the tilemap.
* **tile**: an [image](/types/image) that matches the tile you're looking for.
## Returns
* a [boolean](/types/boolean) value that is `true` if the tile at **location** matches the **tile** you want to check for. If not, `false` is returned.
## Example #example
Make a tilemap with two columns of wall tiles with a different color for each. Set a sprite in motion and cause it to bounce on walls. When the sprite contacts a tile, check to see what color the tile is.
```blocks
scene.onHitWall(SpriteKind.Player, function (sprite, location) {
if (tiles.tileAtLocationEquals(location, assets.tile`myTile0`)) {
mySprite.sayText("Blue", 500, false)
} else if (tiles.tileAtLocationEquals(location, assets.tile`myTile1`)) {
mySprite.sayText("Green", 500, false)
} else {
mySprite.startEffect(effects.fire, 200)
}
})
let mySprite: Sprite = null
tiles.setTilemap(tilemap`level1`)
mySprite = sprites.create(img`
