Draw on the Game Boy and share direct to your phone with a #QRCode!

If you draw something I'd love to see it!

Also interested in hearing which QRCode scanners + web browser combos work for sharing the drawings.

@bbbbbr Itch.io link is 404-ing.

@trashheap Thanks! Forgot to make it public. Fixed

@bbbbbr Thank you for making it public! Im going to have to pop this onto the analogue pocket and give it a whirl.

@bbbbbr genius concept!

@bbbbbr Super fun!

@bbbbbr This is amazing! Great work.

@bbbbbr couldn't get my phone's built in camera app (simply called "Camera" on my old Galaxy S20), but uploading a picture of the qr code to https://scanqr.org (first result in a search) and copying the result into Firefox one the same phone worked just fine (but copying into Chrome did not).

@bbbbbr For the work flow I kinda wished that holding B would just switch to the fast cursor because it'd make navigating within the canvas way faster and it'd allow getting to the sidebar quickly too.

[bbbbbr@mastodon.gamedev.place]

@Jeltron That's a great idea. Easy to prototype too.

Any thoughts about the cursor motion/inertia? I wanted it to be a little easier to draw curves instead of just straight and diagonal, but it's tricky to balance that with against precision and not being too sluggish.

[bbbbbr@mastodon.gamedev.place]

@cobb Thanks, that's helpful to know!

I'm not yet sure why some QR Apps won't scan the code. Might be some url validation in them which rejects mime encoded blobs.

[jeltron@pocketpixels.club]

@bbbbbr Yeah that's a tricky one. I was just wiggling the dpad like an etch a sketch with the cursor set to slow. Have you seen how drawing programs do brush stabilization? They make it so where you're drawing has a little string that pulls a point just behind the cursor. Something like that type of smoothing might help if it's possible on Gameboy. Like usual you've done something that I wasn't sure was even possible in the first place by making this program.

[bbbbbr@mastodon.gamedev.place]

@Jeltron I didn't know about that, I like the concept. A simplistic smoothing algorithm is do-able, maybe harder for advanced ones (kalman, etc). Making a note.

Re etch-a-sketch:
- I should try adding MBC7 accelerometer support. Might be fun.
- I got a gb-303 music cart from IG and was thinking about adding support for drawing with it's knobs (here's video of a little test app I made to read the knobs).
