Here's a simple tunnel effect I did to test out doing pixel effects with userdata. Not super inspired, but it does run at 60fps at full resolution!

I made an editor that pops out in a window, since I'm having trouble exporting it properly so I'll drop the src here

local editor
local gui

window(150,200)

menuitem({
    id=0,
    label="Save to ram",
    action=function()
        store("/ram/cart/main.lua",table.concat(editor:get_text(),"\n"),{})
        notify("saved to /ram/cart/main.lua")
    end
})

menuitem({
    id=1,
    label="Run from ram",
    action=function()
        create_process("/ram/cart/main.lua")
    end
})

function _init()
    gui = create_gui()

    editor = gui:attach_text_editor({
        x=0,y=0,
        width=150,
        height=200,
        syntax_highlighting=true,
        show_line_numbers=true,
        markup=false,
        embed_pods=true,
        has_search=true
    })

    window {
        title="Popout editor"
    }

    editor:attach_scrollbars({autohide=true})

    editor:set_text(fetch("/ram/cart/main.lua"))
end

function _draw()
    gui:update_all()
    gui:draw_all()
end

A quick gamepad tester I wrote for picotron to test the gamepad api. The tester also supports changing the player number to use multiple gamepads.

I labeled the buttons according to their corresponding keyboard inputs, and layed out the buttons according to how they mapped on my xbox controller.

The two buttons in the middle are buttons 6 and 7, which the readme lists as reserved, but I think represent start and select buttons.
Button 6 seems to map to the start and home buttons, as well as the enter key.
Button 7 doesn't seem to map to anything yet.

As of writing there seems to be a bug in picotron where higher player numbers don't work correctly.
player 0 works properly, but odd numbered players, such as player 1, will have their inputs split across two controllers.

I've also confirmed that as of writing picotron only fully supports up to 4 controllers. If you connect a 5th controller, half of their inputs will register on player 7, and player numbers higher than 7 aren't supported so only half the controller will work.

Update:
Now highlights the player tab when that player's controller has active inputs, making it easier to find what player your controller is mapped to.

Update 2:
Now reports analogue values for the sticks

so i want to run pico 8 on my recalbox without an emulator, how would i do that? via ports?

I've been thinking about ways to execute fast pixel effects on Picotron, and so I'm looking for ways to perform the effect entirely in userdata-land, and display the results as sprites. I've tried a few approaches, none of which seems to be quite ideal.

1. Do math on f64 userdata, then render that to the screen. This gets me fast math operations, but of course the rendering result is completely garbled. I suppose some pack-ints-into-floats type nonsense could be attempted? But with just basic arithmetic ops this seems like a bad time.

2. Do math on f64 userdata, then cast that to u8 in a loop. This is a lot of time spend calling getters/setters in a loop, and may not be any better than pset, not sure.

3. Do math on integer userdata, then cast to u8 using the userdata:convert() method and display that. This would work fine if I could figure out how to get fast fixed-point going. Unfortunately, div and mod are slow, and shifts don't seem to work.

I think my preferred resolution would be to allow convert() to go from f64 to u8, but anything that allows any kind of math with fractional quantities, either floating-point or fixed-point, would be great. Drawing f64 userdata with spr with implicit casting would be great too. Just trying to avoid explicit loops to get to u8....

First tiny catridge for the Picotron!
Drop some celebratory sand into your tiny window and shake it around, why not? :)

The left side is cut off on user profile pages as well

(sorry if this is the wrong subforum, couldn't find one that worked great)

EDIT: The issue has been resolved! You can find your Lexaloffle key at the top of the Humble purchase page!

=================

Congrats on the release, @zep! Just purchased Picotron. I've been watching its development with an excited glimmer in my eyes over the years! It really looks like the perfect mix of specs (really excited about the wavetable sound in particular!) and I'm excited to start exploring my creativity with it.

I've been looking at how to add the product to my Lexaloffle account following the instructions on this page https://www.lexaloffle.com/account.php?page=activate, but have not had any luck with it. Is it correct that the Humble purchases page for Picotron simply does not have the 'Lexaloffle Account Activation' button yet?

I'm trying to make a classic synth pluck sound: a couple of detuned saw oscillators, plus a resonant lowpass filter that quickly opens up when a note starts, then closes back down. Unfortunately, I can't quite figure it out. I have an ADSR envelope modulating the filter cutoff, but since the envelope has a positive polarity and higher lowpass knob values = lower frequencies, the effect is exactly the opposite of what I want: the filter immediately closes down on note onset, then more slowly opens back up.

Is there any way to flip the sign of this modulation? Am I thinking about this the wrong way?

It's out! We're all stoked, it looks great. We're all excited to explore its possibilities.

But we are also PICOTRON PIONEERS...

So post your bugs here!

Hi,

I'm thinking about drafting a trailer/ad for Lexaloffle's fantasy consoles (PICO-8, Voxatron and possibly Picotron). if anyone has any carts they want to submit for a highlight reel, or any ideas for the trailer, please leave a post in this thread!

I am using the stock player character system to select a player character at the beginning of the game, and I placed 8 characters in the world. However, the 3 that I created (and placed) last have a permanent "P1" pointer floating above them and can't be selected. Is this normal? If so, how should I go about my character selection? If not, can I fix it?

a fruit ninja demake. WIP

I am trying to run PICO-8 on a Chromebook via the Linux support console Crostini. I have followed a guide (https://www.lexaloffle.com/bbs/?tid=36473) to get it to function, using both the linux x64 and x32 versions of PICO-8 but neither have worked, giving an error saying 'cannot execute binary file: Exec format error' when run. I am seeking support from other people who have experienced similar issues with running PICO-8 on Chromebook.

My system is running on V 122.0.6261.100 (Official Build) (64-bit) of Chrome OS and the laptop build is a Lenovo Duet 3. I have not set up any additional applications (let me know if any are needed) for this process aside from Crostini.

I am attempting to run v0.2.6b of PICO-8.

Help Marcel reach their friend to chill while the hero is away!

This is my first take at making a platformer. I spent all my time and effort on getting a character controller that felt good, so the story and visuals are very bare-bones (pun not intended but let's roll with it).

Controls

• Arrows to run
• O/X to jump

The music can be turned off in the pause menu

Tips

• The longer you press the jump button, the higher you jump
• During a wall slide, you can detach from the wall by pressing the down button
• Similarly, you can go through one-way platforms by pressing the down button
• Spikes don't hurt you if you move away from them

Hello everyone! I'm developing a platformer based on My Hero Academy and for some reason, my player is able to jump while touching a jump-through tile, when they should only be able to jump if they're on top of it.

Does anyone know why this happens?

Code for jumping:

--jump
if btn(❎) and player.landed then
 player.dy-=player.boost
 player.landed=false
end

Code for landing:

if collide_map(player,"down", flags.base) then 
 player.landed=true
 player.falling=false
 player.dy=0
 player.y-=((player.y+player.h+1)%8)-1
