I discovered that the following statement was making my PICO-8 application crash with an error of [2] 76047 illegal hardware instruction /Applications/PICO-8.app/Contents/MacOS/pico8 crash-example.p8.

print("|⁴ュ◝り◝T⁷Z◜」\0ク◝あ⁶¹²ヌ◝、\0$²へヲ¹\0そ◝メ¹ˇャ9\0ヌ◝ク¹エャ■\0\0\0⁙²Nョ:\0005\0て³ᶠョ◜◝な◝ャ\0キ¹オ◝{\0]¹x⁵ュ◝◀\0ャ\0uャハ◝キ◝け²ンャ9\0\n\0し³テョ⁷\0009\0J⁶◆ッ\0\0k\0オ³9⁵³\0ッ◝し⁶u²⁸\0は◝O⁷")

This does not happen when running the line from pico-8-edu.com, or from the web export of the cartridge.

I am on version 0.2.6B of the Mac OSX PICO-8. My platform is a 2014 MacBook Pro running macOS 11.7.4.

Bot the Builder

Play as a robot and build platforms to scale up a mountain. With 19 puzzles, approach every solution creatively and get to the top!

About the game

The game was originally made for the GMTK 24 game jam ("Built to Scale"). This version (v1.1) adds multiple QoL changes and improvements, to be a fun and fresh experience for anyone :)

In the cart you'll find:

  • An in-game speedrun clock (if beating games fast is what you want)
  • An in-game placed blocks counter, to improve your personal score
  • An option menu to customize the game to your liking (activate or disable music, screenshake, HUD elements and change inputs)

Hello,

I'm a beginner programmer, trying to figure out good practice. To be honest, I get a lot of joy out of refactoring code even though I know it's more important to create something of value. Seems to give my brain comfort.

I've been creating a card game and realised that one of my challenges is that I have a card object that has some game logic associated with it but I'm also mixing up a bunch of presentation information on that card. It's getting messy.

Which got me thinking about trying to separate concerns. Wondering what the community's view is on an approach like below?

The general idea here is that a card needs to know nothing about its presentation (but is linked to its presentation). It's a bidirectional link, a card_view is related to its card.

Obviously, in a game where there are not a lot of objects, this might be overkill.

function _init()
	renderer = Renderer:new()
	animator = Animator:new()
	deck = {}
	x_offset, y_offset, i = 0, 0, 0

Stratagem is a match-3 game you swap adjacent gems on a grid to gain points. Unlike other popular match-3 games, any group of gems that directly touch on the grid are cleared, not just ones that are in the same row or column. While you can make any move on the board that swaps two touching gems, you can only make three moves that don't clear groups of gems before the game is over.

Changelog

v0.2.0

  • Fix #24: rearrange state transitions to act like other Match-3s
  • Fix #20: add menu option for resetting leaderboard
  • Gem resprite by squaremango
  • Fix #18: Bring back pico-tool & update cart building scripts
  • Fix #12: add credits screen

This is a fighting game test made completely through ChatGPT and Claude a couple months ago.

I am not going to go any further with this, but maybe someone will find it useful for their own project.

Player 1 uses the default controls. I belive X is heavy attack (slower but does more damage) and O is light attack.

You can do a quarter-circle-forward motion plus one of the attacks and it will throw a fireball (like a hadouken from Street Fighter: down, then down+forward, then forward+attack but in one smooth motion). The attack button used determines the speed.

the issue

when you open the readme on Linux, it's empty.when you open it in an external editor, it shows -[[pod]] then a load of gibberish. for whatever reason, when i try to copy paste said gibberish, it comes up with this:

--[[pod]]
lz4

I'm not sure if it's user error (I'm quite new to picotron) or something else.

Tweetcart- all source code is 280 characters or less.

Edit in Education edition here!

The blue lines indicate the trajectory of simulated particles as they are pulled by the planets' gravity. If a particle hits a planet (one of the colored outlines) it colors its originating pixel the color of that planet. If a particle doesn't hit a planet within a certain number of steps in the simulation, it colors the originating pixel black.

Hey all!

So, as it turns out, porting Picovania to Picotron was pretty straightforward! I've decided to
continue, now that constraints have been lifted!

Pardon our dust...

the current features feel.

  • Made another pass on the stage one music, and rebalanced the audio

(8/23/24)

Initial release on Picotron!

LEGACY

(8/9/23)

  • Several powerups have been added, as well as all sub-weapons
    • Stopwatch: Freezes time to give you some room to breath, but it costs quite a few hearts to use
    • Cross: Emits a blinding holy light, destroying all enemies on screen! One use on pickup only.
    • Invisibility potion: Makes you invincible for about ten seconds.
  • The whip upgrade is now fully working. Grab 1 to get a chain whip. Grab another to make it longer!
  • I've sprinkled candles throughout the level to play with. Every available item and sub-weapon should be attainable, but some of the more valuable stuff is placed in harder to reach areas. Can you find them all?
  • First Enemy has been added; The Bone Tower! (Thanks again for the art @HeyNetters. I saw your Bone tower and
    was inspired for my first enemy!)
    • Acts more like a sentry than anything, but where it lacks in mobility it makes up for in toughness. Recommend at
      least a chain to deal with these guys. Watch your footing...

(11/22/22)

  • I've decorated the map a bit, using assets and ideas provided by @HeyNetters. Many thanks go to them for the art! This is all preliminary for now, but these just looked too good to not include them.

  • Chain upgrade has been added. The chain graphics reflect the first upgrade, and the added length reflect the second. Collect the whip powerup to upgrade.

  • Gameplay pause added upon collection of the whip powerup.

  • Whip has been fixed so that you can no longer hit things behind you. Still need to look into that janky
    animation...

  • Thanks to suggestions from @dw817, Simon's walk speed has been increased a bit, with matching animation. The whip also stays out for just a bit longer.

  • Minor changes to small heart to keep it from flying around so much.
  • Tweaking pass on SFX.

(8/26/22)

Sorry for the long delay, guys. I recently started a new job, and I have less time to work on this project now. I do, however, fully intend to see this project to completion. I need to work on some systems that can cut down on repeated code in here, as the token count is getting dangerously high. Despite that, I'm happy with where it is at so far. Let me know how you guys like it!

  • Candles have been added. Until I can work out a feasible spawning system, these are hard coded. Whip them to make
    items come out.

  • I have mocked up a status bar along the top of the screen. This is all subject to change as I figure out what will
    fit and what will not.

  • A game clock is in place. It ticks down in seconds, and once it reaches zero, you're dead. There isn't much you
    can do about it at the moment, but I thought it would be fun to add, and it was really simple to implement. The
    clock will even start to beep after awhile, just to give you some unnecessary stress.

  • Hearts have been added. You now have a limited stock of ammunition. Whip candles to find more.

(7/21/22)

  • Boomerang can now be caught. Small reason to post an update, but I thought it was important.

  • Boomerang graphics rearranged so it animates like in the original game.

    This may be the last update for a little bit. The code for climbing stairs MUST be rewritten before I will
    continue. While it works great as it is, the code is just too darned bloated right now.

(7/20/22)

  • All throwable weapons have been added. Hold ❎ and press ⬆️ or ⬇️ to cycle through them,
    and press ⬆️ and 🅾️ to throw one. Like before, you can throw 3 at a time!

  • Holy water was redrawn to not be so huge.

(7/19/22)

  • Holy water has been added, press ⬆️ and 🅾️ to throw it. You can throw 3 at a time.

  • Simon's sprite has been redrawn to make him more detailed and look a lot less scrawny. Many thanks go to the
    Discord community for their feedback on this matter!

(7/18/22)

  • Stairs now work in all 4 directions.

  • Plenty of stairs have been added to the map, so play around and let me know if anything breaks horrifically.

  • It is no longer possible to jump when a block is directly above the player.

(7/16/22)

  • Commented out the code and formatted it so anybody could take a look and decipher it all...

  • Taking a hit will now interrupt your attack.

  • Player can no longer warp through the ceiling when hurt.

(7/15/22)

  • Player health, hurt state and death are implemented. There aren't any enemies yet, so for now you
    can press ⬆️ and ❎ to beat yourself up. These are disabled while on stairs...

  • Continue screen has been added

  • Made a pass on music and sound effects. I feel like the music instrumentation is way better now, and many of the
    sound effects are improving as well!

  • Initial HUD elements added. There are here only for a visual to pair with testing health and lives for now.

(7/12/22)

  • Changes to walk and stair climbing movement and animation speed. It felt just a tad sluggish before...

(7/11/22)

  • Stairs are in progress. Right now there is only up-right and down-left movement, but this is a pretty good proof of concept. Whip is disabled for now while climbing them until I flesh out that aspect.

  • The bottom of the screen is now a bottomless pit, and you will die and be reset.

  • A small map to test out the mechanics and play around in.

  • Preliminary artwork has been added to make the view a little more interesting

(7/10/22)

  • Jump physics have been reworked and the jank is now gone for the most part. I feel like the jumping is in a pretty good spot now.

  • Initial work on the whip has been started. The animation is just a little janky, but I'm working on that :)

  • I am currently prototyping ideas for stairs. I haven't added stairs yet, so don't try...

(6/26/22):

  • Basic movement is implemented; Walking, ducking, jumping and hard landing are in. There is one little niggle
    with collision and platforming. I'm sure you guys will know when you find it. (Edit) I've created a temporary workaround
    for this. Please let me know if you like how it handles. Collision is still not perfect, and you might still get
    hung up, but I'm working on that.

  • First draft of music has been created. Let me know how you like it! I might need to shift things around a bit
    before I release: I've not included everything I'd like to, and I've run out of room due to some initial (less
    than optimal) SFX layout choices.

(6/27/22):

  • I've tweaked the jump physics to more closely match the original game.

  • Invisible walls have been added. I wanted a way to create impassible areas without changing the collision.
    You can test this out near the lone block on the right.

    Now is the time where I sit down and take a class on Picomap by @JadeLombax. I may as well get this figured out
    and implemented now, since stairs will likely rely on it...

Recently, I've been working on a word-typing game called Catreeboard with my son. At the beginning and to simply get the game to a state where we could work on animations and gameplay, I naively created a simple table-based dictionary that is subdivided by length of the word. It looked something like this:

dictionary = {
    {
        "a",
        "i",
        "on",
        "at",
        "it",
        "is",
    },
    {
        "cat",
        "dog",
        "sun",
        "hat",
        "bat",
        "pen",
    },
    {
        "home",
        "love",
        "ball",
        "star",
        "blue",
    },
    {
        "house",
        "quick",
        "plant",

Goal

You are the faithless embryo of an ancient rot. Your body has been magically imbued once more to grant it proper form. With 3 companions, you're tasked with confronting the oncoming threat.

Keep your party members in fighting form and drive back the endless monstrosities!

Controls

As the party healer you can:
O button - Heal target/Reconstitute downed party member
X button - Attack target

Thanks so much for checkin' it out!!

This is my first jump into Pico-8 and it's been a LONG time since i've played around with game development, so lemme know if you find any bugs! I had a ton of fun putting this together over the last month, thanks to many tips and tricks from this community! <3

Okay, here's what's happening.

  1. PICO-8 open, playing a game.
  2. We pause the game (with the Enter key) to go do something away from the computer.
  3. We lock the computer with a key combination (Super+L) - meaning that PICO-8 was the active window before the screen was locked.
  4. We return and type our password on the KDE Plasma lockscreen and hit Enter to enter it.

What we expect: the computer unlocks, PICO-8 is as it was before, paused.

What we usually see: the computer unlocks and simultaneously PICO-8 unpauses.

Just to check, we did the same series of steps with this text entry box in Firefox and Firefox does not register an Enter key press, so I'm guessing this is a weird edge case in how PICO-8 determines if the Enter key has been pressed.

In case the specifics are relevant, we are using Plasma 6 on NixOS 24.05 (Uakari).

Making myself accountable for being more productive. Trying to consider which of my prototypes I want to focus on for the next few months and make it into a fully realized game.

Prototypes include the following:

1.) Platformer - Rival faerie-folk engaged in a game of cat & mouse with environmental repercussions on the line.

2.) Platformer - Dedicated to a well-known comedy character following chapters of his titular movie.

3.) FVS - Fixed Vertical Shooter styled after Galaga, Phoenix, and other games from the classic arcade era.

I have a treasure chest of other ideas that are only partially realized and in need of initial development, while these three have more effort already put in. I will try and settle on one by the end of the week while trying to balance all my other duties; we have a big event happening on Friday/Saturday so that will certainly be the bulk of my attention & energy for now.

Thoughts?
