I WANNA BE THE GUY

the movie: the demake

this is still in pretty early in development(it only has up to tyson)
but it's already fun enough to play and speedrun and stuff

i plan on doing the whole game in the future along with a base-cart for people to make their own levels
but i'm full of stuff to do rn so it might take a while

anyway:
expect updates

Empty Base-Cart

Plans moving forward

Simple Etch-a-sketch tweetcart in 233 chars

Z and X -> Up and down
Left and Right -> as self
shaking is on the menu

the cart:

menuitem(5,"∧",function()s=1end)::_::if s>0then
memset(24576,103,8191)s=0end

Random fireflies that procedurally syncs up in 270 Chr, not bad for a first tweetcart i guess?
Ctrl+r to start again

the code:

s,r,c=sin,rnd,pset p={}
for i=0,200 do p[i] = {}
for j=1,3 do p[i][j] = r(128)-64 end
end::_:: cls()for i=0,200 do for j=1,2 do po=p[i]
p[i][j]=(po[j]+r(2)-1)%128 end
po[3]+=(po[3]>p[flr(r(50))+1][3])and -0.1 or 0.1
c(po[1],po[2],1+s((po[3]/64)*t())%11)
end flip()goto _

Best way to load/store a lot of data?

Fri, 26 Mar 2021 01:54:15 UTC

so, i'm planning on doing kind of a demake of rhythm heaven(with new minigames cuz, nintendo y'know?) but i don't think a single pico cart would be able to hold all music/sprites (i've only been able to hold 8 songs w/ pic-o-beat)
i've been looking around and i saw some options but i have no idea on what would work better for me, this is what i found so far:

compression: there's a lot of code about this here on the bbs that i find fascinating, but have zero idea on how it works to make it do the songs intead of the spritesheet

load a cart per stage: have a main menu cart and load each stage in different carts, the loading isn't great but if it's the best way to do it its allright

load only the music and spritesheet: i remember seeing this somewhere but i can't find it anymore, i imagine the loading would be quicker, and i could easily reuse mechanics between minigames but i have no idea on how to do it

a ton of peeking and poking: have a main cart with all the song and sprite data that "set up" the data on a series of "cartdatas" that can be memcpy-ed at runtime. this would allow community submissions with, i imagine, little to no difficulty but would be really awkward for the user

probably some really simple stuff idk about: if you know, please tell me

PIC-o-BEAT

PIC-o-BEAT is a rhythm game that really paints a picture

How to play?

How it works?

--bad code ahead--
this is how the images are stored

	[0x0]

first the score then the texture right under
the program first scans the top image to a buffer from a pointer to some pixels ahead

  for i=0,17 do
   local posx, posy = ((point+i-2)%imgs)+imgp.x,imgp.y+flr((point+i-2)/imgs)
   if i==17 then
    if sget(posx, posy) == 10 then --is  yellow
      scrbuf[i] = 1
    elseif sget(posx, posy) == 12 then --is  blue
      scrbuf[i] = 2
    else
      scrbuf[i] = 0
    end
   else
     scrbuf[i] = scrbuf[i+1]
   end
  end

we also update the pointer every 2 beats of the first sfx channel using stat(), this way the speed of the pointer follows the speed of the song (this method could be used to follow odd time signatures/rhytms by using %3 for example)

  c2 = c1
  c1 = stat(20)
  if c1 != c2 then
    if c1%2 == 0 then
      point+=1
      readspr()
    else
      return false
    end
  end

if we press a key we check the buffer at the right spot to check if you got the note right
if so, we paint a dedicated piece of the spritesheet with the right texture and set the buffer with a "empty" note
if you press a wrong note, we also paint it with the texture but with offset colors, and put a "wrong" note on the buffer
if you press on empty you paint the texture and set a "not empty" note

 if inpa then
   if scrbuf[2] == 2 then
     sset(imgx,imgy,sget(posx,posy+imgs))
     scrbuf[2] = 10
   elseif scrbuf[2] == 1 or scrbuf[2] == -1 then
     sset(imgx,imgy,(((sget(posx,posy+imgs)+1)%15)+1))
     scrbuf[2] = -1
   elseif scrbuf[2] == 0 then
     sset(imgx,imgy,sget(posx,posy+imgs))
     scrbuf[2] = -3
   end
 elseif(...)

Once the song ends we just check the score textures and keep count of the errors
if black, is the end texture black?
if B or Y, is the end texture and img texture the same color?

for i=0,imgs*imgs do
    local imgx, imgy = ((i)%imgs)+112,flr((i)/imgs)
    local posx, posy = ((i)%imgs)+imgp.x,imgp.y+flr((i)/imgs)
    if sget(posx, posy) == 0 then
      if sget(imgx,imgy) != 0 then
        errors +=1
      end
    else
     if oneb == false then
      if sget(imgx,imgy) != sget(posx,posy+imgs) then
        errors +=1
      end
     else
       if sget(imgx,imgy) != sget(posx,posy) then
        errors +=1
       end
     end
    end
  end

and to do the medals you just peek and poke at the designated hex

and that's basically the whole mechanic, to create "expasion packs" it's just a matter of drawing over the textures, or creating new music but i've drawn too much already lol
