Not sure if this is actually a bug or expected behaviour. Seems like a bug to me. That said, don't know if it's a problem with PICO-8 or just with Lua in general.
Here's the problem. If I define a metatable using the __metatable property then the __tostring method doesn't get called automatically (by print for example) when expected.
m = {}
x = setmetatable(
{},
{
__index=m,
__metatable=m,
__tostring=function(self)
return 'blah blah blah'
end
}
)
print(x)
print(tostring(x)) |
Output:
[table] blah blah blah |
So, I can call the tostring() function explicitly but it's not called automatically by print as I would expect. If I leave out the __metatable property though it works as expected:
m = {}
x = setmetatable(
{},
{
__index=m,
__tostring=function(self)
return 'blah blah blah'
end
}
)
print(x)
print(tostring(x)) |
Output:
blah blah blah blah blah blah |
Putting the __tostring function in m also doesn't work:
m = {
__tostring=function(self)
return 'blah blah blah'
end
}
x = setmetatable(
{},
{
__index=m,
__metatable=m
}
)
print(x)
print(tostring(x)) |
Output:
table: 0x30bb9cc table: 0x30bb9cc |
Nor does giving m its own metatable with a __tostring method:
m = setmetatable({}, {
__tostring=function(self)
return 'blah blah blah'
end
})
x = setmetatable(
{},
{
__index=m,
__metatable=m
}
)
print(x)
print(tostring(x)) |
Output:

this is a falling sand game! it's essentially a remake of one i've posted before, but completely rewritten to be performant with the latest version of pico-8. it also has a lot more features. feel free to experiment! it's also posted on itch and you can find its source code, which is released to the public domain, on github.

Sokoblox is a hybrid of two classic puzzle games: Sokoban (the push puzzle) and Bloxorz (the rolling block puzzle).
See if you can beat all 15 levels!

My six year old and I made this game for her upcoming birthday. She was inspired by paper mario and the idea of a pinata that ran away.

This prototype was made for Pico-View, a monthly web-zine hosted here on the BBS and also on NerdyTeachers.com.
You are challenged with taking on this visual effect of enlarging and shrinking your sprites as the main mechanic of your game! Practice using SSPR( ) function to have more control of your sprites this way.
You can:
1) Play this prototype as-is, and share your highscores below.
2) Take this cart, and edit it as much as you'd like to create your own spin-off!
Don't forget to share it here on the BBS with the tag "Prototype Party" so we can see what you were inspired to create. And keep your eyes out for more in the coming issues of Pico-View!

Was listening to some old compositions of mine and realized that I had a nice little instrument that hadn't made it into the midi library!
For the demo, I used the same trick I used then, and split the melody across two separate SFX so the tails of each note could ring out while the next note played. Bit of a faff to do, but it produces a very good effect.
As noted in the cart, at least to me, it still sounds good and has a harp-ish vibe with various combinations of Buzz, Dampen, and Reverb; Detune doesn't work because the bulk of the SFX is the triangle wave.

I don't understand how it took me so long to make this mod....

It's been about a year since I've touched my platformer project, so I wrote this simple little dice roller to get back in the swing of things.

a small game about a fish, made in 9 hr for Alakajam #17
left and right to wiggle
the river-flow should very slowly get faster / get as far as you can (the number of screens traversed is counted)
red spikes hurt / yellow scales give a bit more life / watch out for the light-blue currents / plants can block you, but only horizontally
(also my first 'finished' cart)

This is my first attempt at a Pico-8 Game. I made this for my wife to play with our cat Aesop. When he is hungry feed him eggs, burgers, steaks, and turkey. When he is full take a nap and then go eat again. Just like a real cat.

I'm new to PICO-8. This is a little game I've been putting together as I learn. Nothing special or exciting (the enemies don't even fight back yet), just something to get my feet wet with and expand on as I go.
Arrow keys move the frog left and right. X key to shoot.

Hello.
While some years back I did write a fairly complex cart to draw snowflakes on the screen, they were not incremental. That is they stayed the same number on the screen at all times.
I was noticing in the BSNES emulator they do this instead. They add one snowflake per second on the screen-saver. The effect I think is rather pretty - so here is my version of it for Pico-8.
The code is documented quite thoroughly.
Be aware of some numbers you can fiddle with that are defined at the top of the code:

EDIT1: Bugfix
EDIT2: Yet another bugfix, passives did not get applied correctly
EDIT3: (Hopefully) fixed the slowdown when lots of fish are on screen

XXX is an addictive and deterministic score-em-up where you maneuver an agile ship across treacherous environment.
Features
- Addictive 30-second game loop
- Refined, skillful gameplay
- ZERO randomness; deterministic physics
- Beautiful low-resolution graphics
- Learn about doomed planets
- Reach the highest score you can!
Controls
- Arrow Keys to steer your ship
- Press X to activate your boost, once every 30 seconds.
- Press Z to open your Solar Atlas, which lets you view planet orbits, and learn about their composition
- Press "Enter" for options
Credits
- Brook.p8 - that's me!

- Shoutout to trans folks and autistic people everywhere, and especially autistic trans peeps!
- Made for LowRezJam 2022 (I forgot to post it here oops)
- Inspired by Outer Wilds
Meet the System
- Xun
Remaining lifespan: 22 seconds
A hot and burning ball of code and plasma, facing imminent collapse
Our beloved sun at the center of our system - Xerth
Orbital radius: 29,000 pixels
Its neon sea, which neatly divides the planet in half, creates the perfect habitat for life as we know it
We call it home <3 - Devril
Average temperature: 450°F
Due to the high heat and an atmosphere rich in oxygen and carbon, this planet is constantly lit aflame
Possibly supports marshmallow-related life?? - Keple
Planet radius: 1200 pixels
This body's orbit is extremely off-center, passing both closer to and further from the xun than any other planet
Due to the extreme fluctuations in temperature, and its mossy poles, it does not support life. And if it did, it'd probably be lame anyway. Like moss or something. - Bolong
Orbital eccentricity: 0.42
Tidally locked with the sun
Due to its fast movement as it approaches the sun, Bolong's dark side is notable bigger and denser than its sunny side - The Cube
Sides: 6
???? What???
We don't know how it got here - Debris Belt
Number of asteroids: 1.27 million
That's a lot of rocks
The ring appears to extend beyond our observable universe
Thanks for playing!

Hello.
I have noticed this sample program I wrote does not play 2-notes blending, one after another. No, it cuts off the first one and then plays the new one - despite being on an entirely different channel.
@zep, I think this qualifies as an error. Could you fix it, please ?

A simple platformer. I built this from scratch (using some samples as reference), to get a feel for implementing a simple game design. I made all the tiles, sounds, levels and code myself, using Pico8's inbuilt designer
