I am making a game where you press B to toggle on and off platforms. How do I turn walls on/off at these tiles when B is pressed? Game: [https://makecode.com/\_0HsDMRCU0cL4](https://makecode.com/_0HsDMRCU0cL4) Note: the mechanic isn’t used until the third level. ---

You can do this: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/9/9a21de734fbf41e9f0c0cf387ec865ca9c778c21.png) and enter the wall that you want to toggle on in the “array of \_\_\_ locations” and you can change what wall you want to replace (set walll on/off) and what tile you want to change it to (set \_\_\_ at value) ---

Oops! I thought it randomly deleted my post, so I made a second one, which is this one. Don’t mind this post, thanks.
