Picket Puzzle
Trailer
The picket line swells as factory after factory walk out on strike. For the exploited and the oppressed of the world, this is the moment -- but time is short. The arms of the state are mobilizing to halt your advance. Can you lead the workers to victory?
As strike captain, you must learn how to overcome obstacles, deal with police blockades, seize government buildings, and win the army over to your side. Brute force will not work here, instead you must think clearly and creatively to succeed.
Once you've started on the road of revolution, there's no turning back!
Gameplay
Unique snake+sokoban puzzler with lots of clever mechanics in the mix:
- Factories add workers to the picket line
- Soldiers can be won over to your side, but only when surrounded
- Police block your path unless you have enough workers to push them back
- Radio Towers take control of the enemy troops - for just one step
- ... and more!
- 40 levels that challenge your creative puzzle solving skills.
- Forgiving design: turn-based gameplay, play levels in any order, infinite undo.
Stuck or confused? Here's a manual explaining all the mechanics: https://docs.google.com/document/d/1-xpxwokgk4aULF7_pv95NIb4ZjaCMkbPgcJhC0xAQh8

I want to make a game using vector animations so I got started on a way for drawing that.
Main tips for speedy drawing:
- Scaling/rotating is slower
- More vector sprites is slower
- Bigger vector sprites is slower
- More triangles is MUCH slower
code here:
[hidden]
--[[ vgfx.lua
vector graphics drawing
=== todo: ===
-more triangulation functions
-tween/interpolate between two vector sprites/polygons
-animation playback
-compression for vector data
-maybe look into userdata for optimisations
-maybe try writing directly to graphics memory if it's faster
also:
-make a vector sprite editor/animator app
=== docs: ===
"vector sprite": an array of polygons
"polygon": an array with 3 elements: color 1, color 2, vertices
"vertices": array of numbers (x0,y0, y1,y2, ...etc)
vertices list should be triangulated, sprv() will NOT triangulate arbitrary polygons
tri() and triraster() are decent triangle drawing functions, for lightweight
vector drawing, skip the vector sprite stuff and just use these
]]
vgfx_wire=false--enable for debug view of polygon triangles
vgfx_precise=false--enable if you have issues with edge seams
function make_polygon(col1,col2, verts)
return {col1,col2,verts}
end
--vector sprite expectations:
-- array of polygons
-- each polygon is an array with:
-- color1, color2, vertices
--vertices expectations:

--draw a vector sprite

local s, cs = 0,0
if rot and rot!=0 then

if (col) color(col)
for p=1,#v do--loop through each polygon in the vector sprite
--prep to draw this polygon's colours
if not col then
fillp(0b1010010110100101)

end

I've spent two hours fixing a nasty bug. The image above is essentially the bug I was trying to fix, except all the steps were spread in three functions, and took a good minute of playing on average before everything aligned just right (or just wrong depending on how you look at it) for it to seemingly randomly occur.
Can you figure out why t[2] is not 8 in the end ?
Hint : Lua arrays and # operator are cursed.
Ideally, I'd like the game to crash at t[i]=8 if possible. Anyone knows if you can add some sanity checks to all array accesses ?

The Picotron palette was quite chaotic and the numbering wasn't very intuitive to me (probably due to being backwards compatible with PICO-8). I thought it might be nice to have an easy reference within reach so I don't need to open a forum post or wiki page whenever I need to work with colors. If you'd like to add this widget yourself, here are the steps:
- create a file named "colors.lua" and place it somewhere that makes sense to you (mine is in /appdata/local/tooltray/colors.lua)
-- colors.lua local GRID_SIZE=20 local palette={0,20,4,31,15,8,24,2,21,5,22,6,7,23,14,30,1,16,17,12,28,29,13,18,19,3,27,11,26,10,9,25} function _draw() cls(0) for i=1,32 do local x = ((i-1)%8)*GRID_SIZE local y = ((i-1)//8)*GRID_SIZE rectfill(x,y,x+GRID_SIZE,y+GRID_SIZE,palette[i]) print(palette[i],x+3,y+3,7) if palette

Goat is a curious, little goat (shocking) who lives peacefully in the mountains. One day, she had an accident and ended up landing on the top of a haunted tower. A tower that would try to kill her with all its means...
Help Goat to survive by charging rocks and trees and dodging dangerous spiky trees and fire balls. Watch out for Goat's stamina level (pink top bar) as she runs out of energy quickly. Recharge her batteries by picking up stamina balls. Use super power when you're in trouble or running out of energy.
Can you get to the end and save Goat?

Hi all,
I've been working on a release of a paid pico-8 cart, but I will be releasing a demo version as well. This may be out of the ordinary, I know, but lets pretend it's a good idea for a moment.
So, with the demo being playable in the browser once it's public on itch.io and here, it feels awkward to not have a straight-forward way to provide a mobile full-version as well.
I'm worried this would be a bit complicated for most users, but... my best idea is to suggest the use of a 'Simple HTTP Server' app to host the index.html and js file locally. I found this app worked great and was relatively simple to use: https://play.google.com/store/apps/details?id=com.phlox.simpleserver
With this app (and its default settings) you copy the index.html and JS file into the directory specified in the app, hit the start button, and then use you web browser to navigate to 127.0.0.1:8080.
I have no idea if there's something similar available for an iPhone.
I hear there are PICO-8 cart player apps available too, but I didn't spot one after a brief search on the play store. Is there something simple available out there I can suggest as well?

Here's a couple of tweetcarts I've made. Nothing too crazy (compared to the other insane tweetcarts I've seen here).
I was messing around with spirals and found some interesting patterns. Every once in a while, the arms of the spiral align and they even count down (6 arms, then 5 arms, then 4...). If you enable line mode, it creates shapes with the corresponding amount of sides (hexagon, pentagon...)
X to toggle line mode
C to stop spinning
Up/Down to speed up and slow down
Right/Left to step forward or back (most useful when it's fully stopped)

Hello! I'm pretty new to Picotron and haven't used Pico8 or similar things before and was pretty
confused with how the sin and cos functions worked. After finally figuring it out I made a
little program to demonstrate their use. Posting it here in case anyone else finds it helpful!

This is pomodoro.p64! A helpful tooltray widget for Picotron that will allow you to follow the Pomodoro system.
Installation
In a terminal:
load #pomodorosave pomodoro.p64(save anywhere you like, I personally have mine at /appdata/local/tooltray/pomodoro.p64)
Then, open up /appdata/system/startup.lua (or create the file if you haven't yet).
Add the following line:
create_process("/path/to/your/pomodoro.p64", {window_attribs = {workspace = "tooltray", x=2, y=2, width=91, height=32}}) |
You can edit the x= and y= coordinates to be whatever you like, but be sure that width and height is 91x32.

This cartridge is an installer and uninstaller for a new globally-available command: 'crc32'.
Installation
Install with yotta:
yotta util install #util_crc32
Install without yotta:
load #util_crc32in your Picotron terminal- Ctrl+R to run installer cartridge
- Press X to install/uninstall as prompted
(You can also manually copy the relevant files from the loaded cartridge from /ram/cart/exports to your system if you'd prefer.)
Description
This command will generate CRC32 checksums for the input parameter you provide, which can be either a file path, a folder path, or a bare text string.

Rationale:
- sfx buttons would make more sense with a hidden mouse
- a couple of projects of mine :)

Hey there! I wrote a small library to make drawing numbers using sprites quick and easy using the output from string.format.
It can technically be used for non-integer values but any symbol that can't be drawn as a number will just be skipped over and a digit-wide space will be left. I wrote it this way so that you can draw a number with either leading zeroes or leading spaces.
There's also a version that allows you to have leading zeroes displayed as sprites too.
--sprite_num.lua --[[ Description: Implements a function for drawing numbers out of sprites. Useful for non-text numbers, like scores for arcade games. Best used with numbers formatted with 'string.format' Requirements: Number sprites need to be stored in contiguous order from 0-9 (0123456789) Optional: A 'const' table containing the following: const.sprite_0 : Integer value holding the sprite ID of the 0 digit. const.number_width : Integer value holding the width of each number sprite. const.lz_sprite : Integer value holding the "Leading Zero" sprite for sprite_number_lz If the const table isn't used, this function call requires its optional arguments. Usage: sprite_number(input,x,y,[sprite_0,sprite_w]) [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=144069#p) |

My first Picotron project. It's a clone of a game called Chain Reaction I used to play on my C64 back in the day.
It's a two player game where you take turns in placing orbs on a tile grid. The object is to be the only player with orbs left on the board. Orbs can be placed on empty tiles and tiles where the player already has orbs. When there are one fewer orbs on one tile than there are neighbouring tiles the tile is said to be critical. Adding another orb to a critical tile will make the orbs splode. The orbs will be added to the neighbouring tiles. If they are occupied by the opponents orbs these change color.
Just try it, you'll understand despite my poor explanation.

It's Conway's Game of Life in PICO-8! The game board is randomized (you cannot set pixels for now) but you can try different tile sizes and speeds (the "speed" is the number of frames before refreshes...). There are some performance issues at full scale. Enjoy!

In Picotron, le shortcut to exit is Ctrl+Q.
But on a french keyboard (AZERTY layout), le "A" is at the place of the "Q" key on a QWERTY keyboard.
So, when I want to do Ctrl+A for "select all" in the code editor, Picotron is exiting.
For Zep: I think you must use KEYCODE instead of SCANCODE in SDL programming (or the inverse). ;)
(Sorry for my bad english)

I'm working on a desktop app for Picotron and I need to detect when the AltGr key is being pressed. I tried
if keyp("altgr") then
but it doesn't work. I've also tried
if key("alt") and key("ctrl") then
and its variants (like "lctrl" or "rctrl") but it also doesn't detect when I press altgr on my keyboard.
Thanks for any help!

IMPORTANT!!
In this version of the browser, websites are currently not sandboxed! This means that a malicious user could make a website that causes you to lose all your Picotron data among other things (it can't affect the host computer though), so I'd highly recommend only using this program on the browser embed here on the Lexaloffle forums.
I'm working on a new version of the browser that fixes this and more, so sit tight until I share it :) I'll post a handful of preview videos of the update here in the comments in the near future if you're curious about what's coming though.
Original description:
HI! I thought it would be neat to have a little isolated version of the internet for the Picotron! This is a very rough start of what I think that might look like (I very limited knowledge of how web protocols or any of that stuff works).
Many of the known bugs are fixed but. There may still be a few here and there tho so lmk if you run into one
Anyway, to add a page to the browsing catalogue, you need to type a comment in this format, replacing the plus symbols with caret symbols:
+PICOSITE+ link + title + about +
Notice where the spaces are placed! this is actually important lol
an example:
^PICOSITE^ https://raw.githubusercontent.com/May0san/piconetdemo/refs/heads/main/home.lua ^ PicoNet Homepage ^ The homepage of the PicoNet! ^
Try to not make your "about" too long.
I apologize in advance for the messy disorganized code lmao. Upon downloading files the browser will create a downloads folder in the root folder if one doesn't already exist. If anyone wants to propose a better standard for this, feel free :)
As for writing the actual page, you can view my examples on this github repo:
https://github.com/May0san/piconetdemo/tree/main
Btw in previous versions of Picotron, the webplayer couldn't run PicoNet Explorer, so keep that in mind.
Most recently, I fixed the draw order issues and changed the browse page so that it should be able to read from multiple pages of sites. I'm also working on a major overhaul of how this "PicoNet" works! Hopefully you can look forward to a major update soon!
Features:
✅ visit and display hosted file with gui data (a "picosite")
✅ catalogue all the sites posted on this forum page into a browser list
✅ allows use of a "gif" which is really just an image with multiple sprites in one and is indexed with sspr to advance the animation. (subject to modification when sitebuilder is complete, will mostly still work the same though.)
☑️ create a "sitebuilder" site (and also corresponding cart) to graphically design and export websites as code
