How to play!

Arrow keys to move! Collect all 16 cookies to win!

This is my first game made with pico-8 and it's kinda buggy but, it was fun to make!

Use the dpad to move head pieces around, join them to tiles (only some tiles join, and only on certain sides), and move your creation to the target area to complete each puzzle.

A wee game for Twelve Days of PICO-8 Christmas 2022. To get the full experience, play it from @TheTomster's menu cart!

Some scenes from other games in the collection:

Wooden Toy Joinery was a 3 day collaboration with my 9 year-old while visiting my folk's place in the south of New Zealand. Yesterday out of nowhere my Dad produced what looks to be one of the first BASIC programs I ever wrote (maybe.. 1985?). I didn't have access to a computer at the time, and this was before understanding what variables are. I suspect I was imitating a pick-a-path adventure code listing I'd seen, but applied to an action game.

I need help with how I want the player to move. I want the movement of the game to be mouse based, i.e I want the player to jump up left when moving cursor to the left of the slime and jump up right when mouse is to the right of the slime. How would I be able to achive this? I've tried to test something if it'll work, and it didn't.
What I tried was
if stat(34)==1 and (on_ground or jump<2) and SX==8 and sy==8 and mouse.x<x then
on_ground=false
jump+=1
dy=dy-1
sfx(0)
end
This doesn't work since whenever the X cord for the mouse is less then the slime X, or x, it still jumps. Is there something I'm not thinking of that could work?

I've already posted this on the Discord and a couple other places, but, well, why not post it here too? Randomly generated snowflakes for the season.

I'm running the latest version (0.2.5e).

Pico8 works fine when you link your own SDL library and change the video driver.... Until you press alt+enter (fullscreen toggle). Pressing that makes pico8 have a segfault under linux:

> SDL_VIDEODRIVER=wayland /opt/pico8/pico8_dyn
zsh: segmentation fault (core dumped)  SDL_VIDEODRIVER=wayland /opt/pico8/pico8_dyn

Same thing with kmsdrm:

> SDL_VIDEODRIVER=kmsdrm /opt/pico8/pico8_dyn
zsh: segmentation fault (core dumped)  SDL_VIDEODRIVER=kmsdrm /opt/pico8/pico8_dyn

But it doesn't happen with the default for linux (x11):

> SDL_VIDEODRIVER=x11 /opt/pico8/pico8_dyn

Hello!

I'm new to programming in general so I'm not really sure how this works, but here's a mini "Introduction" project. Although I did know about PICO-8's existence for a while now, I just never got the chance to actually try it.

(I've been looking at some tutorials on how PICO-8 works so I should be fine.)

Thanks for checking my project out. :)

Controls

You can control the Apple that shows up when you boot up the cartridge.

(Arrow Keys) - Move

PicoMotos v.0.1 Demo

This is an early version of a small game I worked on in September, taking advantage of the few days of the paternity leave. I'm wrapping up a few things, so I decided to put it here as a WIP, although I'm not sure I will move forward.

I tried it with a joypad and the playability is better, playing with the keys might be a little challenging even with the many power-ups frequently spawned.

If somebody tries it I would love to hear some advice!

development log

i started when i got a YouTube recommendation of the 'it is a mystery' meme.
it took me three attempts in 2 weeks (with breaks) to finish this cartridge

most of the 2 weeks were forced breaks, because i had a lot of school work before winter holidays began.

Just updated to v0.2.5e, and found that it breaks a number of my tweetcarts.
The issue specifically seems to be that this shortcut is no longer supported:

if(...)do
--thing1
--thing2
--etc.
end

Now to make things work, I have to replace the "do" with "then". Not a huge change, but it does require a couple more characters, and every one counts when dealing with strict character limits.

Very minimalistic version of the game snake.

It has two easter eggs:

Press (o) to change palette.

Press (x) and (<) at the same time to toggle invincibility.

I know a lot of people have posted functions for drawing cubic bezier curves, but I'm tossing my own into the pot because why not. Just skimming threads, it feels like most people use pset() to draw them pixel by pixel; this one uses line() to draw them segment by segment.

Some animated gifs, because they're fun:


demo of the editor in the cart:

drawing demo, dividing the curve into segments:

drawing demo, dividing the curve dynamically based on pixel precision:

To save you digging into the cart, here's the two versions of the algorithm I'd recommend, based on my testing. If you want to see how fast they run, there's a pause menu item in the code that draws sets of 5000 random bezier curves with a bunch of different algorithm parameters in two sizes - 16-pixel square bounding box and 128-pixel square bounding box - and adds up the total CPU needed at 60 FPS.
