Hey, folks!
I want to build a GitHub Action to automatically export the cartridge as HTML and publish a GitHub Page.
I have two question around this:
- Did someone already do this, or attempted to? Any clues for prior art would be appreciated.
- I'll need to have the pico8 binary published, but I don't know if I have permission to do that, and I assume I don't. Would it be ok to have a cyphered version that I'd decrypt during the build process with gpg or something?
Cheers!

My entry in #TweetTweetJam, in 554 characters.
Cross four levels of increasingly busy traffic, using only the up and down arrow keys!
This was my first time trying a minimal-code jam-- I read various forum tips but I'm sure there's still some compression to be had. Since the jam rules were to use source code only, no spritesheet/map/sfx data, I had the idea of Poke-ing a basic sprite into memory and then using sspr() and palt() to reuse it in different forms... and a little game evolved from that.

This is my pico version of the famous Jump King game that has been release in 2019.
You can get it here if you like the concept https://store.steampowered.com/app/1061090/Jump_King/
-Controls-
You just need to press x and release to jump, the longer you press the higher you go
and you can control your jump with the arrow keys.

My first attempt at a shmup type game. Fairly basic with 3 enemy and weapon types in addition to bombs and life drops.
The code is a mess. I might go through and refactor it one day, but I'm mostly just happy to be done =)

Hi @zep,
Unless I'm missing something obvious, I seem to have stumbled on a weird bug.
It seems that inside an FOR..LOOP (potentially other places too),
if the incrementor is something other than 1 or 0.5 (such as 0.4),
then even though PRINT is "saying" the value is 1.4, it is not comparable with that value
(perhaps a precision/rounding happening in PRINT?)
Code below:
cls()
?"-- works -----"
for z=0,3,.5 do
print(z)
if(z==1.5) print("😐")
end
?"-- fails -----"
for z=0,3,.4 do
print(z)
if(z==1.6) print("😐") --<<<< NEVER hits this
end |

Inspired by a game on Amstrad CPC this is my attempt make a game in the snake category. This is my first ever pico8 game.
15 Levels
2 Types of enemy, CPU controlled snakes and the vicious seeker.
3 Types of bonus
S to make your snake short
L to gain a new life
Ghost gain one new life every three levels.
I hope you all enjoy this as much as I enjoyed playing the original.

Update v1.1
Minor update to allow input buffering as suggested.

This is a work-in-progress. You can run around and collide with objects. There is an enemy with which collision is detected however the enemy does not move. More to come in the future.

Quick and simple suite demonstrating API references from the pico-8 fandom site.
The default setup (in the editor) displays many preconfigured examples.
As a bonus, the output is a neat & tidy guidelined file folder diskette design.
There's some magic numbers and kinks that need to be ironed out but here it is.
Intended to be used as a fast barebones engine or just a learning example kit.

3D texture mapping with tline (plus some other stuff, like wireframe rendering, and solid color polygon rendering). Did this as a learning project, to study old-school pre-GPU 3D graphics.
Thanks to freds72 and johanp for inspiration & example code.

Try to catch the moving rectangles in the smallest possible space.
When the space is reduced by 50% the next level becomes available, but you can still make the current one smaller.
The smaller the space, the more points you will get.
v1.1
- Fixed an issue where not all levels could be reduced by 50%
v1.0
- Initial version

I noticed that people relatively often ask for a way to draw an inverted circle and don't have an easy way to implement it, since it requires a bit of math that can be difficult to derive without experience. I decided to make a quick cart and standalone function to do that! This isn't amazingly efficient, and it only does circles (not ellipses), but it is a drop in function:
Update: new function utilizing trig, faster and now subpixel!
x=x or 64 y=y or 64 r=r or 32 left=left or 0 right=right or 128 top=top or 0 bottom=bottom or 128 local p=r*6.28 if(top<y-r)rectfill(left,top,right,y-r,c) if(bottom>y+r)rectfill(left,y+r,right,bottom,c) [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=83816#p) |

I'm trying to use anonymous inline functions and I'm finding some weird behavior when they are on tabs.
Putting everything in tab #0 works:
x=1
function _draw()
cls(1)
print('x is '..x)
end
(function()
x=2
end)() |
And moving the inline function call to tab #1 works:
x=1
function _draw()
cls(1)
print('x is '..x)
end
-->8
(function()
x=3
end)() |
But putting an inline function call on both tab #0 and tab #1 does not work:
x=1
function _draw()
cls(1)
print('x is '..x)
end
(function()
x=2
end)()
-->8
(function()

First Cart! I wrote an N queens solver because that was what was in one of my csci classes some time ago.
