People have made mockups of how a "real" PICO-8 console and controller could look... But what about the devkit keyboard?
- Small, compact keyboard layout, like 75%, 65% or 60%
- Mechanical clicky switches
- Retro keycap profile (ADA?)
- Iconic PICO-8 font and colors on the keycaps
Here's a quick 75%-ish mockup I made (in ISO-NO since that's what I use, but a real one would probably be ANSI or JIS?). It's pretty busy, printing is WIP, and it's probably a bit too big; I added the F key row to try out symbols for GIF recording and stuff.
Group buy when?

I am writing data to a p8 file from a Python program - format for 0x0-0x3200 ROM range is ok.
Issue is sfx section - each sfx (68 bytes) is actually written as 84 bytes (??) with empty bits left and right.
I have no clue what is the masking/bitshifting/... logic between my input value and the resulting p8 string.
Example:
poke4(0x3200,0x1234.5678) cstore() |
produces:
__sfx__ 000100003813534011000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 |
wtf??

And you thought the ArduBoy sounded neat.

They're working on porting NES emulation, and it comes with CircuitPython, so maybe a pico8 implementation wouldn't be out of the question.
That said, I might just pick one up and get busy. Who needs only 128 horizontal resolution and a static color palette?

Can somebody explain why my steering code (well, @2darray's mostly) sometimes goes bananas and sine's itself off-screen rather than heading to the next waypoint? It only happens occasionally and I can't see why and always to the left.
Sometimes it'll do this...
Would greatly appreciate any help and a math explanation. It seems to happen more often if I decrease the turning speed from say
turnspeed=2*(pi/180) |
to
turnspeed=0.5*(pi/180) |
but that doesn't explain the example gif because the distance between node 5 and 6 is quite far.
Edit: I've uploaded a version with a simpler sprite and a vector to show the current target node.

First attempt at writing something for the pico8 with my daughter.. am loving this thing so far!
There are a load of things left to finish in this (and a lot of lovely bugs!), but thought I'd share now it's actually playable for some feedback.
Please be gentle :)

Hi all!
Based on my embryonic understanding of polar coordinates, you can draw a spiral by incrementing R and THETA in lock step.
So I put together this little blob of code:
-- draw a spiral -- in polar coordinates, you -- do this by incrementing r -- and theta at the same time. for r = 1,99 do theta = r / 100 x = r * cos(theta) y = r * sin(theta) pset(x,y) end |
And that almost yields a spiral! At least it yields a curve. Yay curves!
Is it possible that I'm drawing my spiral, I just need to somehow scale it down so that the dots are contiguous and maybe the angle of turn is sharper?
Any clues are appreciated. I'm just trying to gain an understanding of the basics and build from there.
Thanks!

A mashup of Snake and Tetris. Made for the Retrospelsmässan (http://www.retrospelsmassan.se/eng/) Game Jam.
Music and sound by sfabian. The music is a mashup as well; if you're smarter than me you just might know of what.
This was demoed as basically an arcade game so optimized for that, with hiscore entry etc.

Early version with opening doors but hardly anything else:
Much later version with sliding walls, triggers, and enemy AI being tested:
Severe performance issues in the latter.

First try at PICO-8. It was lots of fun to learn about and play with. I think it's a great tool to quickly test small ideas. Hopefully this will be the first of many small PICO-8 experiments.

My game, Wight of Steel, is a sequel to a game I made on Scratch about a year ago. However, unlike its predecessor, this game focuses on challenge, precision, and speed. Albert, a black mass with glowing white eyes, goes on a journey to become the Wight of Steel. You probably won't beat this game, but it is 100% possible. If you beat the game without using a password, the time it took for you to complete the game will be displayed.
Controls:
Move horizontally - Left/Right arrows
Jump - Z
Fast Fall - Down arrow
Reset - Hold up arrow and press X
Holding the Z key will make your jump higher.
Holding the down key as you are jumping will make your jump shorter.

First game with PICO-8 (already loving it!).
Your standard spaceship game but you only earn points while boosting. The closer to the right edge, the more points you earn (+1/2/3/4).
Shooting at asteroids can save you, but ammo is limited. Pickups give you +50 ammo.
It gets harder the higher your score.

Description
Who needs gameplay when you have ACHIEVEMENTS? Don't worry about beating levels, finding ways to kill enemies, or beating the final boss...there are none. Focus solely on your ultimate destiny...doing random tasks that have nothing to do with anything. Metagame yourself with ease! Self-satisfaction never felt so...artificial!
Controls
Use the arrow keys...if you dare.
Version History
- v1.02 (May 17, 2019)
Fixed a bug with the 0th achievement description, and with holding UP immediately upon starting - v1.01 (May 6, 2019)
Made some important secrets even more secret - v1.0 (May 5, 2019)
Initial release

Hi,
I made a small demo of a function I have been working on. It is called rspr and can draw sprites with any rotation.
It has the following signature:
rspr(sx,sy,sw,sh,a,dx,dy,dw,dh) -- sx,sy,sw,sh - pos,dimensions in spritesheet -- a - angle -- dx,dy,dw,dh - pos,dimensions on screen |
It takes the angle in the same format as sin and cos and draws the sprite rotated around dx,dy.
You can scale the drawn sprite with dw,dh and it can draw sprites of any size.
However, large values for dw and dh cause some serious performance losses, so you should avoid scaling up sprites to unreasonable sizes.
Due to this slowdown, I would really like to have this function implemented natively in pico-8. What do you think, @zep?

Hello. First time poster here.
I've uploaded an asteroid mining WIP. It's attempting to generate asteroids of different composition and size.
You can move through them with left and right arrows.
I used the 3d demo code from Picozine 2 with a randomly deformed icosohedran mesh for the asteroid body. Instead of then rasterizing the faces, I've opted to spin the asteroid body for each palette color. This, ideally to give a sense of dust scattered around.
Do these look like asteroids? Am I just putting off rasterizing the faces?
Any feedback greatly appreciated.
Inspirational community here. I'm really enjoying Pico-8.

When I run pico-8 v0.1.12c Rapberry Pi version on my Freeplay CM3, the gamepad is not working anymore. The gamepad was working on previous version of pico-8.
I got this error message :
the path /dev/dri cannot be opened or is not available
I don't know if the message is related to the gamepad or not
Maybe someone can help?
