I've tried specifying the channel but didnt change anything.
My sound is definetly working, the volume on the sfx's notes are higher than 0 and I can hear the statup bleeps from Pico-8.
BUT THE MUSIC DOESNT PLAY

Hi all,

I'm just getting into Picotron, but have dabbled with PICO-8 for a long time.

Given the way /ram/carts main.lua works, what is your initial directory structure like and how are you doing source control (git, github, gitlab, codeberg, etc)?

Are you mostly using the Picotron or have you switched to a parent OS IDE like VSC or NeoVim?

THX1138 in advance, Pond.

(PS - here is a screenshot from what I'm working on, PacHac, a Pac-Man roguelike.

Evolving Ants

This is a very basic implementation of a genetic algorithm, partly inspired by this Code Bullet video, with a few additions to improve the evolution speed and reliability. It's nothing fancy, but I found it fun to experiment with, so I thought I'd share it.

Each "ant" has a DNA consisting of a list of directions to move each frame, which starts off completely random, but though the process of mutations and "natural selection" evolves into a path to reach the goal.

To improve the evolution speed and reliability, the ants are evolved gradually by giving each generation slightly longer to reach the goal. In addition, the mutations to the DNA are biased towards the end of the path, so more ants have a chance to explore the end of the path before they die.

Hey pico 8 community. I recently started making some demos and carts for myself and my friends. Although I have been struggling with collisions. Most tutorials use fget and mget. I want to use them, although I don't understand the parameters that are used.
I am not looking for a one size fits all code. I am just looking for a explanation for how they work, and what the parameters are used for and how they work in functions.

Thank you :D

Hi @zep!

pico8 0.2.6b / linux:

cls()
if (false)?1 --hi
print(2)
print(3)

expected output: 2 3
actual output: 3

Here's an altered version that works as expected:

cls()
if (false)?1
print(2)
print(3)

(this prints 2 3, as expected)

3 things seem required to trigger this bug:

1. shorthand if
2. shorthand print on the same line
3. !! further text after the shorthand print (" --hi", in this example. but just a single trailing space triggers the bug too)

When these are all true, the next line seems to get scooped up into the shorthand line. This can include attaching an else to the wrong if, like in this more complicated example:

cls()
if false then
 if (false)?1 --hi
else
 print(2)
 print(3)
end
print(4)

expected output: 2 3 4
actual output: 4

no idea if im making a post correctly here, never have before. but I was curious if there is any info how to open a downloaded cart for picotron to look at how things were done or change things?

Hi again!

Title is self explaining...

I'm out of sprites! I need to display what's on the other pages. How do I do that?

Hibou

Hello good people of the Picotron! First time posting. I apologize if I<m not posting in the right forum, but I<m a bit lost in the current layout of the site.

I'm a amateur programmer who never went too far qith this hobby, so I thought maybe something meant to be "easy" like Picotron could be a thing for me, the eternal wannabe game designer.

My question to day is about tables.

I can<t quite get them to work. I use simple one dimension arrays, but I need more of a Pascal-type of record, and when I read the Lua documentation, it seems to be possible, but my code doesn<t compile when I try to create tables with more than one dimension or different types of variable. It<s a syntax problem. I know what I want to do, but I can't find the right syntax.

For instance, in my RPG, there will be a party of six characters. So I need a table with at least a string column for the name of the character, a number column for the character sprite number, one column each for the chacter<s abilities. At the end of the day, there will be a lot of data in that table.

portation from scratch of my Pico-8/tic80/lowresNX game in #picotron as deluxe arcade version.

controls: (<-) (->) (O-Z) shoot hammer.

gameplay: see the attract mode.

enjoy!

Title says it all.
I'm making a horizontal scrolling game with a map 32 screen wide and 1 screen tall, and with the player using extra colors different from the enemy colors. (enemies can't be over or under the player).
For this, I'm using screen rotation, but now I can't use print to display text any more as it appears rotated.
Has anyone already implemented a 90° rotated print function ?

Hi, I encountered a waveform corruption bug while trying to move SFX as part of a multi-composer collaboration project.

On version 0.2.6B

Reproduction steps:

1) Make a custom waveform in SFX 0
2) Make in SFX 1 make a sequence using SFX 0
3) Make in SFX 2 make a sequence using SFX 0
4) Move (cut and paste) SFX 0 to SFX 4
5) Move (cut and paste) SFX 1 to SFX 5
6) Move (cut and paste) SFX 2 to SFX 6
7) Check SFX 4, the data will be corrupted

It seems that this can happen with other combinations but this is the procedure that caused the bug to happen and is reproducible on a fresh cart.

The corruption seem to be an inversion of the sign of alternating sample of some sections of the wave

Celeste but a black hole is chasing you.

The black hole speeds up over time. Here is everything that increases it's speed:

1. New level (Biggest increase in speed)
2. Death
3. Dashing (Smallest increase in speed)

Getting berries decreases speed.

If the hole is more than 2 levels away, it starts to get a speed multiplier.

The formula for speed goes something like this:

(distance is distance between blackhole and roof of current level)

(0.025level + 0.01 deaths + 0.005 dashes)/berries + ((floor(distance)256)*2)

We definitely need an option to download carts in splore. I bought this for my steam deck expecting the standalone app to be, well, standalone. I have to reboot my whole system to access the web browser and file explorer needed to download and add carts. It's very frustrating that such an essential feature was ignored. I doubt there's any chance for a refund, so I guess I'll just have to beg for features that should have been included from the start. Maybe if I'm lucky it'll be added in less than a year. It's only been 9 so far..

Maybe this is overly salty, but it's very frustrating that an implied feature isn't actually present when it's the whole reason I paid for the standalone app in the first place. Buyer beware I guess...

A bug fix version of mamono pico by @65c02
https://www.lexaloffle.com/bbs/?pid=128341

Fixed :

• crashing at end of levels
• impossible to win levels
• not dying when killed by a monster that would have made you level up

Remaining known bugs :

• you can mark a monster even after killing it, and this can disable showing the red number of the monster
• some rare crashes from menu after game over, unknown cause.

Done :

• damage is now the same as the original game

Todo :

• blank pause menu
• Remaining ennemy count in status bar
• timer
• high scores
• Max difficulty
• custom levels
• wraparoud
• mage (fireball chording)

I want to make my own raycaster game in picotron and I have been following this blog written for a pico-8 raycaster. I get an error when I run this and I am not sure what I should do to fix this issue. Help would be much appreciated.

Other than the code, all I did is make a sprite in slot 1 and draw a simple map in the map editor.

function _init()
	cam={
		x=12,
		y=12,
		a=0,
		w2d=2
	}
	scrx=0
end

function _update()
	controls()
end

function _draw()
	cls()
	map(0,0,0,0,16,16)
	circ(cam.x,cam.y,2,12)
	--for scrx=0,480 do
	--	raycast(cam,scrx)
	--end
	raycast(cam,240)
end

function controls()
	if btn(0) then
		cam.a+=0.01
	end
	if btn(1) then
		cam.a-=0.01
	end
	if btn(2) then
		cam.x+=cos(cam.a)*0.5
		cam.y+=sin(cam.a)*0.5
	end
	if btn(3) then
		cam.x+=cos(cam.a)*-0.25
		cam.y*=sin(cam.a)*-0.25
	end
