So, I've been thinking about switching instances. I started on mastodon.social because I didn't really know anything else, but mastodon.gamedev.place seems to be where everyone I interact with is at.
Is switching instances pretty painless? Will I notice any material differences if I switch?
@eniko I learned about fixed-point math from what's effectively the GBA development standard, tonc. I believe it describes the same thing you're saying, but with different phrasing:
"Not only do the decimals multiply, the scales multiply as well."
@bd oh, awesome! Is Oni the new name for "badlang," or a different language?
I've enjoyed seeing your posts on developing that language here. Perhaps one day I'll use it to make something for the GBA!
@slembcke Based on what I'm seeing, the NES has a little less than 29,780.5 cycles per frame (via nesdev.org) and for the GBA it's 280,896 cycles per frame.
I can see how, with approximately a tenth of the cycles, you'd more quickly reach for precomputed values!
@slembcke Currently I'm calculating the hflip positions per frame, but if I'm understanding you correctly, there's no reason I couldn't calculate the hflip positions at build time.
That's a good idea!
Players can sense the common sizes that appear on the screen, so meta sprites can make things feel a lot more natural + less boxy. They can also lead to more efficient OBJ VRAM usage. This sprite could technically be a 64x64 sprite, but it'd take over 2x the VRAM!
