> Some of my summer school students like Pokemon, so I made this demo to show them how a game like Pokemon could be made with Makecode. It’s far from perfect, so any suggestions or critiques are welcome. Four questions:
> 
> Does anyone know of an extension that could help with keeping track of HP in between battles?
> 
> The fight with Gary is activated when the player crosses a sprite that blends into the ground. Does anyone know how to make a variable change when the player crosses a certain y or x coordinate? I feel like that would be a better way to activate battles.
> 
> Can walls only be added to sprite maps? Can invisible walls be added to background images?
