Hello world, I tried to make a Bejeweled-like game in blocks and found it very difficult, so I created a “sprite grid” extension that can track sprites on a grid. The extension is here (early beta): [https://github.com/microsoft/arcade-grid](https://github.com/microsoft/arcade-grid) And the game is here: [https://makecode.com/\_RbDi9mYx6TwJ](https://makecode.com/_RbDi9mYx6TwJ) Grid extension blocks: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/de8aff17d476e47d8e2ecd594d145899fa8905ee.png) Cheers, Daryl ---

This sound very helpful. Could you group the blocks maybe? It’d be great to see a minimalistic example. ---

Here’s a much simpler example: > **[test arcade-grid](https://arcade.makecode.com/48923-47294-17514-16860)** > > Made with ❤️ in Microsoft MakeCode Arcade. Directions to move Hit A to swap the sprites Hit B to call our current coordinates ---

Some TODOs: - Doesn’t work with multiple sprites per location yet - Requires a tilemap to be present (although this might be a good thing) - Can get out of sync with real locations, e.g. if a sprite moves via velocity (which is actually done intentionally in GemCrush above and works well if used in combination with “snap”. But it could be confusing) ---

The game is amazing. Period. Only problems are that the gems occasionally don’t move down. But still. Amazing. ---

Thanks!! If you see the problem again and notice anything weird that might have caused it, let me know! I think it probably has to do with the speed of simulation and large physics updates happening between events firing sometimes. Or just a logic bug on my side. ---

@darzu it also happened to me ---

Thanks, I got a repro now as well. I’ll look over the code when I get a chance ---

Awesome game! I hope to see [puyo puyo](https://youtu.be/Ogk_AJv3Gww?t=104) next. My personal favorite arcade game of all time. ---

Thanks! Nice! Seems kind of like multiplayer tetris? A modern game that seems similar is “Tricky Towers” ---

It’s sorta like if tetris met street fighter. For a long time I had a TV in my apartment dedicated to nothing but puyo puyo ---

Haha well it sounds like we need an arcade cabinet dedicated to puyo puyo in the team room! ---

I think you should add some sound to your amazing game 🙂 ---

Hey, does this work with an 8 × 8 tilemap? (Not the color-coded extension one, using the regular tilemap APIs) ---

Great question. I haven’t tested it with 8x8 (since it’s basically impossible right now to use 8x8 in blocks), but in theory it should work. Likely there’s a bug or two that would need to be fixed. ---

Oh, and I forgot to say that I’ve been using it with an 8x8 tilemap and it works like a charm! ---

This looks very promising, but unfortunately the examples aren’t loading for me. I get _A namespace declaration cannot be in a different file from a class or function with which it is merged_ errors in the JS console. Does it need to be updated? ---

Yes sorry about that, we have a bug that we’re trying to fix shortly. If you click “Edit Code” it should open okay [Next page](https://forum.makecode.com/t/gemcrush-and-sprite-grid-extension-beta/1842.md?page=2)
