# get Tiles By Type

Return an array of tile locations from the tilemap that contain the specified tile.

```sig
tiles.getTilesByType(null)
```

## Parameters

* **tile**: a tile [image](/types/image) to search the tilemap for.

## Returns

* an [array](/types/array) of tile locations from the tilemap that have the tile specified in **tile**.

## Example #example

Make a column of tiles from top to bottom of the screen. Set a sprite in motion and set it to bounce on walls. Every `5` seconds, find the column tiles in the tilemap and set them as either wall tiles or regular tiles.

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