Important:
This game is very fast and contains fullscreen flashing effects. Flashes can be disabled by turning on the "reduce flash" option in the pause menu (-/enter).
The only way out
is through...
Blast your path to freedom and high scores measured in lightyears! Inspired by classic F-Zero games and Pico-8 bangers like BAS.
Features:
- Incredible speed!
- An evolving wormhole generated by multiple cross-modulating oscillators.
- Probably more control schemes than are necessary.
- The most metal soundtrack I could squeeze out of Pico-8. 🤘

I created a small cat wallpaper that looks at your cursor and blinks if the cursor gets near.

Hello everyone, how are you doing? I'm trying to do something here and if you guys could help me somehow it'd be nice, I'm already grateful for your attention.
The thing is I was able to achieve the "rotation around a point" for Sprites ( in this case a circle ), but the issue is that I want to have multiple objects rotating around a point while starting at different "steps" of the rotation itself ( I'm attaching a image to explain it in more detail).
The code I'm using is the following:
MAIN.LUA
--sincos math
timer=0
scr={
w=128,
h=128
}
opt={
spd=.5
}
pix={
c=12,
x=0,
y=0
}
cir={
timer=0,
a=false,
spd=.5,
init=3,
o=20,
c=12,
x=0,
y=0,
r=6
}
function _init()
cir.x=scr.w/2
cir.y=scr.h/2
pix.x=scr.w/2
pix.y=scr.h/2
end
function _draw()
cls(1)
pset(pix.x,pix.y,pix.c)
print("speed "..opt.spd)
for entry in all(circles) do
circ(entry.x,entry.y,entry.r,entry.c)
end
end
function _update60()
update_keys()
for entry in all(circles) do
entry.timer+= entry.spd/60
entry.x= pix.x+cos(entry.timer)*entry.o
entry.y= pix.y-sin(entry.timer)*entry.o
end
if(keys.down) then opt.spd-=.1
elseif(keys.up) then opt.spd+=.1 end
if(keys.right) then pix.x+=1 end
if(keys.left) then pix.x-=1 end
if(keys.activate) then
make_circle(pix.x,pix.y,opt.spd,15,12)
end
if(keys.delete) then
circles={}
end
end
-- methods --
-- make_circle(x,y,s,o,c)
|
UTILS.LUA
--utils
circles={}
function make_circle(x,y,s,o,c)
local obj={
timer=0,
a=false,
spd=s,
o=o,
c=c,
x=x,
y=y,
r=6
}
add(circles,obj)
end
function update_keys()
keys={
activate=btnp(🅾️),
delete=btnp(❎),
right=btn(1),
down=btnp(3),
left=btn(0),
up=btnp(2),
}
end

Thanks in advance for any help and have a good day!

SpritePaper
A general tool to use sprites a Picotron wallpapers
to begin, simply place the cart at
/appdata/system/wallpapers/ and select it as the chosen wallpaper from the Picotron settings.a settings file will be automatically generated at
/appdata/sprite_bg/settings.podthere is also a readme file inside the cartridge which goes a bit further in depth on what all the settings do

Edit: updated to include a few more optimisations
This is a simple raycasting demo for Picotron. I wanted to check out the performance. It now manages 60fps most of the time thanks to optimisation suggestions by @freds72 and @Eiyeron. Rays are scaled to one third of the screen width to achieve this.
It is an implementation of the DDA algorithm, which is more efficient than a basic marching forward algorithm. The basic algorithm is included in the package if anyone is interested.
I used the extended palette to dither/darken the colour based on distance which does help to enhance the visuals.
Controls
Move using the arrow keys.
The 2D overlay map can be toggled on and off with the 'Z' key.

Does what it says on the tin. Lets you see what's eating up your CPU time. If you make an extension to this, I'd love to see it.
API:
profile.enabled(detailed,cpu) Turns on and off profiling tools.
detailed: Whether or not to display results of profile calls.
cpu: Whether or not to display total CPU usage.
profile(name,linger) Starts or stops a profile. Accumulates between profile.draw calls. Extremely cheap when profiling is disabled.
name: Arbitrary display name indicating which profile to start or stop.
linger: Whether or not the profile should linger even if the profile is never called between draws.
profile.draw() Draws profile and CPU information to the screen if they are enabled. Extremely cheap when profiling is disabled.
profile.clear_lingers() Clears any lingering profile information.
Example:
include("profiler.lua")
profile.enabled(true,true)
local frames = 0
function _update()
profile("_update")

Can, Uncan
Can and Uncan are tools for archiving folders and files.
Use
For easy transfer of a single file, rather than multiple files for the same effect.
Install
Move can.lua and uncan.lua from /ram/cart to /appdata/system/utils.

The regular poke memory method to get the coordinates of mouse in pico-8 doesn't work in Picotron, and I want to add buttons that can react to the clinking in my programs, any examples?
usually while I was working in pico-8, I used to create and object and follows the the mouse, and as the object collides with sth, program runs , but can't detect clinking.

Making my first game on chromebook! I will keep posting. Also made in edu edition of pico 8.

Now in stereo!
Just a short little proof-of-concept for streaming PCM output in Picotron. Could stand to be streamlined and cleaned up a fair bit (and commented better!), but hopefully this gets the idea across. The idea is to set up a few different sfx instruments playing different wavetables on adjacent rows of a pattern, use stat() calls to track the currently playing row, and update non-playing rows with new samples. There are a few gotchas to work around - setting up the instruments is a little fiddly, and Picotron crossfades instruments between rows so some samples need to be written to multiple instruments.
Use the left and right arrows to change the audio buffer size. Values >=8 seem to work well on web, and it looks like I can go as low as 3 on desktop Picotron on my machine.

A screensaver featuring 20 coloured rectangles wiggling around the screen.
Controls are shown on startup.

NOTE: mouse locking seems to be broken on the web player for now, so to try the instrument editor you should load the cart in Picotron instead (i.e. load #visitrack).
Mouse locking also behaves strangely on some platforms (e.g. mac); I added some settings (accessible through the menu) to change the sensitivity and direction, to see if that helps.
VisiTrack is a music tracker, an alternative to the SFX editor provided with Picotron. This is still a work in progress!
(NOTE: this cartridge requires the last version of Picotron, 0.0.1f)
VisiTrack also contains a fully functional instrument editor, which should be able to do anything the default sfx editor can, but presented in a different way.

Hi, NO THIS ISN'T A OVERLY EASY GAME!
its a little test i made to try out tables and multiple sprites
THANK YOU NERDY CODING FOR THE LUA MANUAL
Enjoy!

tline3d misses sub-pixel precision and generate incorrect samples at borders.
note: tline3d adheres to the (correct) rule of filling [x0//1;x1//1[
how to reproduce:
- run attached cart
- left: per pixel
- right: tline3d
- notice border artifacts & texture wobbling

Made a wallpaper that can react to mouse position and movement. It uses some userdata stuff that I've shared before. There's extra settings inside _init(), which I've set to be a bit mild to make the effect less distracting.
