A couch multiplayer game for those who like blowing things up.

Gone Fission! is my take on a strategy game that was a popular PD/Shareware title for the 16 bit microcomputers. To win, eliminate up to 3 other players by blowing up your tiles and claiming their squares.

How To Play

⬅️⬆️⬇️➡️ - move cursor
❎ place atom
🅾️ next player (2+ human players only).

  1. Place an atom on any empty square on the board.
  2. You can use your next turn to place an atom on another empty square or on top of your current atom.
  3. After up to 4 atoms are placed on an empty square (2 in corners, and 3 in sides) they explode, throwing the atoms onto adjacent squares and turning them your colour.

Following some experimentation, I've found a couple of issues with sandboxed apps and how they are given permissions to read/write files outside of the 'special locations'.

Loading cart with sandboxed workspace app can cause data loss

When you load a cart, Picotron helpfully reopens the workspaces you were using to edit that cart. If one of those workspaces is a sandboxed app, however, the app appears to be given write access but not read access.

This results in the app 'opening' the files, but just creating blank, new files and then immediately saving the blank versions over the original files in RAM. This happens without the user initiating a save or doing anything beyond loading the cart. This makes it very easy for a user to lose data if they save the cart before noticing the issue (yes, I am speaking from experience...)

This assumes all the loading/saving is done through wrangle_working_file, I haven't tested otherwise.

The behaviour can be replicated by creating a sandboxed copy of code.p64 and using it to edit a cart, then saving and reloading that cart.

My first ever finished (or as good as) cart :) I tried to make a demake of the solitaire minigame from Zachtronics' Last Call BBS as I've been playing it a lot on my phone. I've only included mouse controls, which I know isn't recommended, I might come back later to add button controls as well if I feel like . There's also no auto solver so you'll have to drag the cards to the foundations manually.

How To Play

This solitaire variant works in a similar way to klondike-solitaire. You can stack cards of alternating colors and decreasing values, card stacks can be moved onto empty columns. Clicking on the deck in the top left will deal out three cards, you can hover over the cards to see their values. When the deck is empty a free cell is unlocked that can be used to store a single card. To win stack all cards in the foundation piles on the left from ace to king! :)

Strawberry Src

A slightly-less-simple code & text editor
Author: Matt Sutton / @xietanu.bsky.social
Version: 1.2.2

Overview

Strawberry Src is intended as an equivalent app to Picotron's in-built code or text editors, with new quality or life improvements to make navigating and editing code and text easier.

Change log

Version 1.2.2

  • FIX: Strawberry Src now fully works sandboxed, and the message given when running it sandboxed has been removed. A few features that require file system access are not available, but these are minor. Big thanks to Zep for all the work on recent versions to make this possible!
    (If you want to unsandbox it to get those features, right-click on your local copy and click 'about strawberry_src.p64', then uncheck the box in the bottom-left corner.)

  • FIX: Added a workaround for the default app bug, so now you can open files in Strawberry Src without making it your default app.

Version 1.2.1

  • FIX: Fixed a crash that could occur when a string preview was generated for a multi-line string. Multi-line strings currently not supported for string previews. Thanks to @klautless for the bug report.

Version 1.2.0

  • FEATURE: Added string previews. Hover over strings to see how they would be rendered - useful when using control codes. Thanks to @CannonTheWildWulf for the suggestion. Option to disable provided.
  • FEATURE: Added TODO: tracking in code files. Comments with TODO: are highlighted and logged, and can be seen in a sidebar similar to bookmarks. Clicking on the task will jump to it, clicking on the checkbox will complete it and clicking on the x will delete it.
  • FEATURE: Added ctrl-pageup/pagedown to jump to the previous and next function defined.
  • FIX: Fixed a freeze caused by the character ' and syntax error checking in some circumstances. Thanks to @demiskeleton for reporting the bug.
  • FIX: General improvements to performance, especially with dense and large files. Should now maintain a stable 60fps under all reasonable circumstances. Thanks to @Sounds for help with this.

Version 1.1.0

  • FEATURE: Added file previews. See features for more info. Thanks to @CannonTheWildWulf for the suggestion.
  • FEATURE: Added ctrl-click/middle click on filepath strings to open the related file.
  • FEATURE: Added filepaths to autocomplete, so if you start typing a string with a filepath, completions based on your filesystem will be offered. Thanks to @klautless for the suggestion.
  • FEATURE: Strawberry Src now alerts you if you're running it sandboxed and prompts to unsandbox it.
  • FIX: Fixed a rare crash related to the syntax error checking.
  • FIX: Fixed some issues related to saving while sandboxed (however, other bugs beyond my control mean it should still not be used sandboxed)

Version 1.0.0

  • Initial release

On MacOS 15.4.1 every attempt to store gui tables crashes the app and results in "segmentation fault".

eg
local s = pane:active().foot
store("/ram/dev.pod", s )

s is an attached gui element

{
child = {},
width0 = 126.0,
text = "footer",
width_rel = 1.0,
sy = 200.0,
parent = "<PARENT REMOVED>",
height = 16,
border = "rrect",
update = <function 1>,
head = "<HEAD REMOVED>",
z = 0,
height0 = 16,
t0 = 0.0,
draw = <function 2>,
vjustify = "bottom",
sx = 4,
clip_to_parent = true,
width = 126.0,
bgcol = 3
}

( I remove the head and parent from the inspect output from http://github.com/kikito/inspect.lua, to reduce the output)

A simple, procedurally generated vertical platformer / climber.

You change colors on the fly, and only interact with surfaces that match your color.

It's feltkat! In space!

This is a fan game about feltkat by Amatrine. Use the directional buttons to move, collect coins, and avoid spacerocks. Help feltkat make it to the planet!

This is my second game ever, so the code isn't very good, but I had a lot of fun making it! There's one extra life at 20 coins, one at 40, and one at 70, but they only spawn if you've lost one or more lives. Feedback is appreciated :D

hey guys, can you please explain the hit function in my code. I used a tutorial for it but i want to understand it.

x = 63
y = 35
dx = 0
dy = 0
grid_x = 0
grid_y = 0
map_tile = 0
flag_tile = 0
function _update()
dx = 0
dy = 0
grid_x = flr(x/8)
grid_y = flr(y/8)
flag_tile = fget(mget(grid_x,grid_y))
if btn(⬅️) then dx = -1 end
if btn(➡️) then dx = 1 end
if btn(⬆️) then dy = -1 end
if btn(⬇️) then dy = 1 end
if hit(x+dx,y,7,7) then
dx = 0
end
if hit(x,y+dy,7,7) then
dy = 0
end
x += dx
y += dy
end
function _draw()
cls()
map(0,0,0,0,16,16)
spr(2,x,y)
end
function hit(x,y,w,h)
collide = false
for i=x,x+w,w do
if fget(mget(i/8,y/8))>0 or
fget(mget(i/8,(y+h)/8))>0 then
collide = true
end
end
return collide
end

Apologies for the delay! I've now taken all the icons made and submitted for the P-icon-tron jam and compiled them into a single cart for everyone to use! Thank you to everyone who participated!

Hover over an icon to view its name, description and author, and click it to copy it to the clipboard. Then you can simply paste it in the icon editor of your files! You can search for icons as well, and by starting the search with @ you can filter by creator. In the hamburger drop down you can switch between full-color, low-color (based on your system theme) and grayscale.

I also recommend checking out Squibble's Icon Base, since it will allow you to set custom icons as defaults for your files and folders!
