# is Hitting Tile

Check if a sprite is currently hitting a wall.

```sig
sprites.create(null).isHittingTile(CollisionDirection.Right)
```

A wall is either a tile set as a wall or the edge of the scene if a tilemap is set.

## Parameters

* **direction**: the direction the sprite moves toward when detecting a wall collision: `left`, `right`, `top`, or `bottom`.

## Returns

* a [boolean](/types/boolean) value that is `true` if the sprite is hitting a wall on the chosen side or `false` if not.

## Example #example

Make a tilemap with a wall going from top to bottom. Set a sprite in motion and make it say "Ouch!" when it hits the wall on its `right` side.

```blocks
tiles.setTilemap(tilemap`level1`)
let mySprite = sprites.create(img`
