Event id #2846 : The 256b sprite font compo
<Post edited by moderator on 22/7-2019 11:21>
* The object of the competition is to generate a sprite-font, in 256 bytes or less code.
* The code should be placed at $0900 and up, but no further than $09ff and must end with an RTS.
* The sprites should be placed at $2000-$2fff, so sprite number $80-$bf.
* 64 sprites are viewed, but it is up to the coder to decide how many he want to generate, but to be considered a font, at least the letters A-Z should be present and readable.
* For the other sprites, you can of course generate the appropriate numbers/punctuation characters, or spaceships or whatever, or not generate them at all and spend all your bytes on doing fancier A-Z, it's up to you to decide what will impress the voters most! :)
* Since the code to actually view the sprites would take quite some space, and the competition should not be about that optimizing the viewer code (or who can do the coolest looking viewer) I will provide the code that displays the 64 sprites on screen, it will occupy $0801-$08ff, and will perform a JSR to $0900 where your font generation code should be.
* The viewer has a number of tweakable parameters that are placed on $0810-$0814:
$0810 - $00=Sprites should be singlecolor. $ff=Sprites should be multicolor
$0811 - Bakground and border color.
$0812 - Sprite base color ($d027-$d02e will be set to this)
$0813 - Sprite multicolor1 ($d025 will be set to this)
$0814 - Sprite multicolor2 ($d026 will be set to this)
Simply change these bytes directly in the viewer code (if you compile it) or in the final binary if you use that, they should not be set from you generator code, as this is also not something that should steal your precious space.
* The generator code may *not* depend on A,X,Y holding specific startup values, or memory being initialized to something specific (you may for example not pull data from the viewer code and use etc.).
* The generator code may use ZP and stack (remember that your code is a subroutine that is being called though, so don't destroy the return address!)
* The generator may use memory up to $3fff
* Max three entries per coder
* The deadline for the compo is two months from now, 2019-09-22 at 23:59:59 CET
* Then follows a voting period of two weeks, a snapshot of the CSDb votes at 2019-10-06 at 23:59:59 CET will be the final result. (modedit: fixed date)
* No prizes except eternal glory.
Here's the viewer code for Kick Assembler usage, with a place to put your generator code at the end:

Yes, code is neither pretty nor optimal, but that's not the point here, the pretty code should be written by YOU! :D
If you prefer some other assembler, here's the prebuilt binary for the $0801-$08ff portion:
sprite_font_view_base.prg
Here are some simple examples I've done to prove that it actually works:
Sprites using ROM font scaled to 3x3 pixel size. $0810 params set to : $00,$06,$0e,$00,$00
example1.prg
Exact same font but with multicolor params set (works this way as well!) $0810 params set to : $ff,$0b,$0c,$0f,$0f
example2.prg

Could have done without that pesky 16K limit. Why? Just... why. =) |

Alright, all entries that are in-compo should now be verified and OK as far as I can tell.
Time to vote people, and try to actually use the available numbers so that we get a fair result, not just 10s for everything! ;) |

Would be nice to make a small intro with the winner(s) sprites used in real world context (scroll or DYSP or whatevs). I think Cruzer should code this since he has never delivered his entry! <3 |

My plan was actually to make a small result-intro showcasing the top three entries and release as a surprise when the results are in, but now you spoiled it! |

Ooh, this one’s going right down to the wire. More voting please, and yes, spread out them numbers, at least until voting is over. |

Only a few more hours. The min number of voters for an entries is 10 and the max number of voters for an entry is 36. Highest CSDb score is 9.71 and the lowest score is 6.71. Highest sum of votes is 350 and the lowest is 74.
These entries can use some more votes!! ;-)
Now go vote!! |

Some raw numbers for the people who like them. Mind you, the ranking deviates a bit from the ranking Shadow used in Sprite Font Compo Results (rank 15 - 18). I ordered the ranking based on CSDb average and then on the sum of the votes. I added the standard average (sum of votes / voters) to show the difference between the CSDb weighted average and the std. average.
