I've noticed that after few hours of using Pico, it starts to get more and more memory, but only when you start opening many different carts in a single, long (few hours, the shortest time I've seen it happening was in a session about 3h long) session. Obviously closing and reopening pico fixes it, but it should be looked into even if it's small (the biggest it got in memory was about 450MB when leaking).
//edit: Also the first sign the leak is happening is that sound starts to get choppy. That was what alerted me of the issue for the first time and I was investigating it for the past 3 days to get to what exactly causes it.

Would save a ton in tokens since brackets are treated as separate tokens.
//edit: Or if you're calling version of function that takes no arguments, ex:
palt(12,true) -- <- brackets necessary --draw something palt -- <- brackets unnecessary since this version of palt has no parameters |
Of course after such bracketless call/definition, a new line would be required, but most sane programmers do so anyway.

Could someone make cart that shows some basic transition effects (crossfade, swipe left/up/down, fade to black, etc) for those who want to have those but don't have skills to code it?

Z to change colours
X to change shapes
LEFT and RIGHT to select presets slot
note: Saving doesn't work in the web version yet!

Just a little love note to the wonderful weekend I had at XOXO 2015. This is a riff on the great interstitial background animation by designer Craig Winslow, plus a little triumphant chiptune thing I wrote up.

HOW TO:
Press Z to make spaceship move to another position
Cart uses ease_in_out_cubic (but feel free to edit and change to another included easing function).
Animation is locked at 0.5 seconds per move (feel free to edit this, too)
ABOUT:
Here is my attempt at providing tweening/easing functions in PICO-8.
They are based on existing work done by many other people.
These functions help you animate sprites smoothly from one position to another, with different types of acceleration and/or deceleration.
I am using them to animate cards around the screen in my Hanafuda Koi-Koi game.

Hi guys!
How are you doing? It's great to see the Forum so active and so many people making and sharing great games, emulators, music, etc... I think it's time to make more tools :) I am working on a sprite editor that will be compatible with Pico-8. I made a little GIF so you can see it in action.
I am open to any suggestions, so please let me know what you think and what you would like to see in future versions :) Cheers

Game I created as my submission for Pico Zine #3 with a couple extra embellishments. Haven't had a chance to playtest it with a pal yet, but it seems like its definitely good fun :)

Added win message, FTW.
Prolly gonna add variable number of colors and maybe even variable block sizes. Anyone have thoughts or comments?

Hello, it's me, Pizza.
I did a bunch of music in pico-8, like the Lemmtris soundtrack and wrote an article about making music for the pico-8 zine. I threw all of the music I did with pico-8 into an album and put it up on Bandcamp.
Well, here it is if you wanna check it out: PIZZAMAKESMUSIC – PICO-8DITION
So long

I'll try to do a Hnefatafl game with Pico-8.
This is not going to be easy ( because I'm not really good with code), but it's a nice challenge.
The game is one of pure strategy, played on a square board. A king and a small force of defenders occupy the centre of the board. A larger force of attackers, twice as numerous as the defenders, occupy positions around the edge of the board.
What I find interesting it's the asymmetry of this game, and the challenge to do the A.I. for it.
Any help, tips, are welcome , especially for the implementation of the A.I.
You can find more info about the game here

Is there a way of achieving a blend mode with sprites?
I'm guessing it would be possible by drawing the pixels individually - checking whether there was already any value drawn in that position... but I fear this would be unusably slow.

Simple raytracer for Pico8. Performance is a bit meh, but all the calculations take their toll.
Buttons don't do anything. It just calculates a picture in about 2 seconds.
I'm using a manual defined gradient for luma mapping.
Have not optimized anything and am not doing shadow rays/ secondary rays at the moment.
Aiming to get something like a classic Cornell box in the end.

So, one of my favorite effects from the olden days was the ability to do glinting / pseudo transparency. Sadly, there is no way to do this in the PICO-8 due to cycle timing and memory issues. I would love to see the PAL call replaced with something that accepts three colors rather than two.
something like: tpal c0 c1 c2, which would take all instances where c0 is drawn over c1 with c2. It would take 128 bytes of memory, but there is still plenty of headroom inside of the draw state structure to accommodate this.

Hi y'all!
I've been working on a reimplementation of Pico-8 in Love2D (Another lua game framework)
Mainly because I wanted to keep working on my games after I hit the token limits in Pico-8
but didn't want to lose the pico-8 feel and start from scratch.
So I'm sharing picolove with you, can grab the source on github.
https://github.com/ftsf/picolove
Requires Love2D 0.9.x from https://love2d.org
Can run a p8 cart with
love . cartname.p8 |
You can modify the love.load function to load a specific cartridge and package it into a .love file (renamed .zip) to distribute.
Have fun!!
Let me know about any bugs you find.
I know there's some issues with removing stuff with del in a foreach loop (causes a bug in celeste.p8), but not sure what's going on there.
Working on adding SFX and Music support as well as p8.png loading.

Pico should accept command line parameter that has cart filename and path in it and when it's present, load it, so I can associate .p8 files with Pico.
