When typing, if a key is released quickly (looks like it's only if it's released in the same frame it's pressed, but not 100% sure) after being pressed, it won't be registered. I'm running into this due to parts of my keyboard layout sending rapid press/release events that are almost always ignored. If I add a delay so the events are spaced out by ~25ms, they start registering reliably. In other words, I suspect Picotron is doing something like this each frame:
# Process key events
keymap = {}
for event in events:
if event.type == "key_up":
keymap[event.key] = false
elif event.type == "key_down":
keymap[event.key] = true
# Now handle events
if keymap[...]:
do_keypress() |
Not sure whether this reproduces on other OSes, but I think this would also manifest itself as dropped keypresses when running at very low framerates. I haven't been able to validate that theory yet though.

Hello !!
I'm learning to code, but I quickly find myself getting sidetracked by trying to implement things I haven't seen in the games I've played yet, and ultimately, I end up wasting a lot of time starting over.
I would like to hear your thoughts on Pico-8, what has helped you progress the most? Was it blind development like I'm attempting without any prior experience? Did you follow tutorials or take courses? Did you look at the code of a game you like to try to understand and learn from it?
Specifically, if you were to start Pico-8 programming today with the hindsight you have now, how would you begin?
Thanks in advance.

This is a fullscreen version of Picotron raytracer, originally created by @eigenbom. It was made since the original windowed version might mess Picotron's desktop wallpaper or theme used by user. It uses vid(3) mode and draws on 1/3 of the screen, and also it draws in slightly more fps. IDK tho, how to move it to the center of the screen.

This is a general purpose geometry/vector library.
It's based on Geometric Algebra (GA) but you don't need to know what that is to use it as most of the standard vector operations you're probably familiar with are here.
I'd be happy to add additional demos (with credit obviously) so if you make something interesting that you want to include let me know.

- Added 3D triple pendulum demo (based on the 2D version here: https://matthias-research.github.io/pages/tenMinutePhysics/index.html)
Hat tip to @shanecelis for this post (https://www.lexaloffle.com/bbs/?tid=54905) which made me aware of PBD and Matthias Müller.

I'm just getting into PICO-8, so this post is largely just me saying Hello World :)
Here's what I have to show (in the best way) for the past few days of learning how to develop in PICO-8 - tutorials have been super useful and I love what I've seen of the community so far!
x to yap with a star effect
arrow keys to walk
hold o + arrow to zoom with rainbow effect
This cart uses snippets from @shy's blog post on animating sprites and @atzlochtlan's Particle Effects cart (thank you!)

____ SPACE ROGUE! ____
Embark on a mission to destroy the enemy aliens!!!!!
Upgrade your ships weapons as you power up in this Space Invader/Roguelite mash-up!
How many enemies can you defeat before re-upgrading your ship?
UPDATE 1.3:
The new update for Space Rogue! adds more core mechanics to make the game be the roguelite that it is! This update adds replay value and provides a foundation for future upgrades & enemies!!!
-- NEW post run shop upgrades!!! Continue your run after your death with an upgraded ship!
- Triple shot!: Fire three bullets at once!
- Upgrade your maximum shield capacity!
- Unlock a power-up that will re-fill your shields to max level. Handy for long runs!
-- Balanced enemy spawns and added a NEW enemy type!!! (this one shoots back!)
-- New sprite for the ships bullets. Adds little more imagination than a yellow brick :)
-- New soundtrack!!! (This one has a bass line! :O)
Also changed up the coding for the way the game handles enemy collision, weapon collision, upgrade logic etc... This will make adding more upgrades & enemies in the future less of a task!
Have fun!

Why I Made This
This tool was created to quickly scan through the pico-8 api, & has many use cases for myself, as I'm the fella' who maintains the stylish though unofficial API site at:

cast:
- change dimension of userdata buffer for 2d operations
buffer=userdata("u8",4096)
-- get a 8x8 sprite out of it
sprite=cast(buffer,"u8",8,8,1040)
|
note: not sure how GC can track these chunks - ok to have that as weak references only.
-
matmul with stride
align with other userdata operations - all ops to allow for source index
use case: array of vectors referenced by index
big_array=userdata(‘f64’,4,500) …. indices = userdata(‘i32’, 4) indices:set(0, 3,89,0,75) out=big_array:matmul(m, indices) |
-
min/max
note: can be done with sort (but overkill) - dot:
cannot operate on partial userdata

It aims to completely replace your smartphone and give you back the focus you need while completing your gems. Just load #phone in the Picotron terminal to get started!
Latest version: 0.5.35
NEW: Automatic updates at boot-up!
PicoPhone now checks the BBS for updates!
So you never miss the latest features.
I've made a video on how I auto-update here:

A simple animated wallpaper or screensaver. Two sides locked in an eternal battle.
The two colors are taken from your current desktop theme.
Inspired by the web version by Koen van Gilst, with some code snippets being adapted from it.
Save as wallpaper
If you haven't already, create a user wallpaper directory in /appdata/system. Changes to the system wallpapers won't persist across a reboot.
cp /system/wallpapers /appdata/system/wallpapers |
Load and save the cart.
load #pong_wars save /appdata/system/wallpapers/ |
Save as screensaver
If you haven't already, create a user screensaver directory in /appdata/system. Changes to the system screensavers won't persist across a reboot.

(Access it from BBS with load #miditron-0)
Miditron!
The first midi-to-picotron conversion tool!
This tool allows you to convert .mid or .midi files into .sfx files used by the Picotron synth tracker.
Just drag and drop the desired midi onto the window, and voila! Your midi is transformed into a .sfx file, conveniently placed onto your sfx folder in your current cart~
Beware!! The tool is pretty barebones though! And far, far from perfect. So you might encounter glitched tracks and have to manually adjust patterns and tracks to fit the desired results.
Some handy tips for adjusting your midi files for an optimal result would be:
- Use only 2/4, 3/4 and 4/4 meters; These meters are the most optimally supported by the tool
- Avoid odd-numbered sections of the song (sections are separated by time signature change or tempo change)
- Avoid using .midi with too many simultaneous notes/instruments (Picotron only supports 8 a time)

A phone keypad to make some tunes with.
The number keys play different notes, and the */# keys are drums.
Controls:
- Arrows: Select digit
- O: Enter digit
- X: Delete (hold to clear box)

Want to get seasick while coding in Picotron? I got you covered! I made a Picotron wallpaper based on my latest PICO-8 game Jaw.
Make sure you have already created your personal system folder inside Picotron and copy jawpaper.p64.png to appdata/system/wallpapers/ and/or appdata/system/screensavers/
Go to the system settings inside Picotron and select "jawpaper" as wallpaper or screensaver.
Enjoy.
Update 2024-04-09: Added Icon and metadata.

this game has a nice peel..
controls:
- Up and Down = move the knife/stick
- hold c = move faster vertically
Lore:
After years of practice this now is the final exam, bob has to make it. After failing school, work and college, his only choice was clear. To eat potatoes, that would make him grow bigger and stronger, or so he thought. Life is hard, it was a constant pressure on him, he could not rest a minute. that's how busy he was, peeling potatoes. The problem was there, bob didn't have a proper peeler, or a knife. He had to use a stick (don't ask how its possible). The potatoes were weird as well, there were only huge ones. In fact, he was standing on the potatoes. But after years of training and hard work, it finally came to him. He knew the perfect job for him. So he applied for a job at peelstation, you know, the place where they make potato games. But here comes the twist. His parents were actually giraffes. But to him, it didn't matter, his goal is clear. He needs to get a 100% on this test, otherwise he isn't the potato master. Just imagine the consecutive, it would be eternal shame. This here is the moment, can YOU make it ?
