Here are my extensions: An extension to create structures efficiently with tile utils (based off the thingy below) > **[GitHub - codinggrizzlybear/tile-stamping-extension: An extension to stamp tiles](https://github.com/codinggrizzlybear/tile-stamping-extension)** > > An extension to stamp tiles > [@How to create structures efficiently](https://forum.makecode.com/t/how-to-create-structures-efficiently/42700/8): > > @CodingGrizzlyBear the tile util extension makes this super easy! here’s some example code for ya: 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. An extension to reset system keys (based off the thingy below) > [@Backspace key resets arcade machine when used](https://forum.makecode.com/t/backspace-key-resets-arcade-machine-when-used/38632/2): > > You’ll need to disable the system keys (or at least disable the Menu system key).
