At the moment, we have 6 native functions to peek and poke the memory :
v=peek(addr, [n] ) you also have v=@addr that is equivalent to peek(addr,1) and peek(addr)
v=peek2(addr, [n] ) and v=%addr
v=peek4(addr, [n] ) and v=$addr
poke ( addr, [value,] [...] )
poke2( addr, [value,] [...] )
poke4( addr, [value,] [...] )

What could be a good extension of this ? The problem is not really the coding part, but rather coming up with conventions that fit well withing the pico8 universe...

poke3 seems like a simple addition, but what three bytes should be copied from the value ?

Pico8 is a little endian universe

XXXX  read from value
..... ignored

       [ pico8 numeric value ]
       [fraction ] [integer  ]
       Byte0 Byte1 Byte2 Byte3
poke   ..... ..... XXXXX ..... 
poke2  ..... ..... XXXXX XXXXX
poke3  ????? XXXXX XXXXX ?????
poke4  XXXXX XXXXX XXXXX XXXXX

Since our standard pico8 numbers are 16.16 bits, we can't go further, poke5 wouldn't make sense.

So with my game, I want to add a title screen and in it would be a start button and controls button.
After the title screen, I publish it.
Edit: I also need to add charming music.

Hi! I'm new here, and want to experience a new type of coding! Or should I say old,hehe. I'm just interested in the coding community, I have some friends over on scratch, MugmanSans_456, HappySans123, TheDerbyKodeer, Demo_of_life, SonicDuhFastGuy, MajorFuego, and Heymugsy! I'm not very keen on coding, but I like learning about it! I'm excited to see what's in store for me! That's all from me, luv y'all!

I'm hoping someone out there can help me solve the ever increasing speed of my bird animation. The goal is to have the ability to put these bird sprites (spr 39 is the static resting bird sprite) all over the map and as the player gets close to them they are disturbed and fly away. A counter ("birds") counts them and this counter is used to alter states later in the game. Everything is working except that every bird that is disturbed flaps it's wings faster than the previous bird. Any attempt to reset this just results in the bird not animating at all and floating away motionless which is kind of comical. :P

My update and draw code for these bad bois are below. Any ideas as to how I could get them to fly away at the same animation speed regardless of how many have been disturbed? Newish to coding in general here so I'm probably going about this the wrong way. FYI, sprite 39 and 19 are both static versions of the bird depending on the background they sit in front of.

So I'm making a game that cycles through colors the sprite can turn into and I'm having a bit of trouble.

And this is the messy code:
if btn(4) then pal(12,2)
end
if btn(4) then pal(2,8)
end
if btn(4) then pal(8,12)
end
if btn(5) then pal(5,2)
end
if btn(5) then pal(2,8)
end
if btn(5) then pal(8,12)
end
if btn(5) then pal(12,5)
end

I was with a friend thinking about making a Pico 8 handheld with A Raspberry PI, and a small screen, and some buttons and a battery, and we want to make it but we have no idea how, it would be cool to also have a teeny-tiny keyboard that we could use on it, we know for the software we can just download Pico 8 on Raspberry Pi OS and have it launch on startup, we could use spore for the games and thats why we need the keyboard. (except if there is a way to get an on screen keyboard that would work similar to those of PS4 and XBox) we want to specifically make it ourselves, and only for playing Pico 8 games. Any help?

I wanted to mess with the speed of a sound-effect during runtime and couldn't find any information on how to do so when searching around. Figured it out with the help of this info about the memory layout of SFX data: https://pico-8.fandom.com/wiki/Memory#Sound_effects

Edit:
The cart code is a bit messy, here's a reusable snippet:

function sfxspd(sfx_i,spd)
	local addr=0x3200+(68*sfx_i)+64+1
	poke(mem_addr,spd)
end

The Socks is a submission to The Pacifist Jam, aiming to explore the age-old question of whether hanging and pairing socks can be enjoyable. Developed within a week, the end product represents only a fraction of the initial plan. However, do you think it succeeded in uncovering the answer?

Controls:

• Click with the mouse

See the jam submission here.

So I want to make a game that's satisfying to play with currently I have this:
function _init()
x=64
y=74
end

function _update()
if btn(⬆️) then y-=1
end
if btn(⬇️) then y+=1
end
if btn(➡️) then x+=1
end
if btn(⬅️) then x-=1
end
end

function _draw()
rectfill
spr(1,x,y)
print("blue square")
end

I'm not sure how to do the rectfill and fill it with color 2. I want to fill the background and maybe make z and x do something
