@CodingGrizzlyBear the tile util extension makes this super easy!

here’s some example code for ya:

> **[tilemap-composite-example](https://arcade.makecode.com/33032-84129-28974-65945)**
>
> an example of how to place a tilemap onto another tilemap

note that this function passes the tilemap in an array because we don’t have tilemaps as a supported function argument type.

i would definitely not use the color coded tilemap extension, because that extension is really just for backwards compatibility with a very old version of arcade.
