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.

MIGHT CAUSE EPILEPTIC SEIZURES
This is similar to my first demo effect but this time it's in color

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 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.

Something is awry at December Village.. Everyone is unhappy; Record time blues!
It's up to Deci to run around and use her boombox to cheer everyone up!
Talk to villagers and find songs to play, Or just take a nap that's fine too.

Kinda a mess and experimental but hope it's chill. Happy holidays!

Futureleste aims to be a mod set decades after Celeste Classic. All the snow has melted due to global warming, and the ways of dashing have been forgotten. Madeline's descendant has to relearn the ancient techniques, and maybe even surpass her ancestor.

A little holiday puzzle game!

It was kinda rushed in 1.5 weeks to be done before christmas, so it may have some bugs...
I think perhaps I could have developed some ideas and made some more advanced complex puzzles, but that will be for a possible sequel or update.

Hope you enjoy anyway! Happy holidays!

Building a PICO-8 Beatemup part 1

Introduction and Aknowledgements

Hello and thanks for reading. This post will be an explanation of the basics of my Ninja Turtles beatemup engine. I'm going to try and explain every single step along the way so this will be a fairly long post. You should probably have some familiarity with basic development but I'll make this as understandable as possible across skill levels.

This blog post obviously owes a lot to a lot of people but much of this specific workflow was derived from these two posts:

Saving Tokens by drakeblue

and

Using _𝘦𝘯𝘷 in PICO-8 by slainte.

Please read both if you have not. Neither is a prerequisite, but you'll be glad you did.

Help Wanted

I’m not a programmer by trade so I’m looking forward to learning from the community by explaining what I’ve created to people who are smarter than me, and receiving feedback on improvements. I hope this helps anyone along their own path. Please feel free to use this code or anything you find in any of my stuff, really. I'd love to play your game some day.

SNOWSTORM - A short graphics and sound demo for PICO-8

Here's my entry for Twelve Days of PICO-8 Christmas 2022! I would've liked to have put something a little more substantial together, but I'm happy with it as it is ❤️

Edit: I wrote this question very late at night, and my grammar wasn't that great. I fixed my bug report to be more clear to users what the issue is.

The function "Box" doesn't draw relative to the screen like boxfill does, and box and boxfill don't round the XYZ coordinates the same way.

  • Added counter of total destroyed asteroids.
  • Added stats of number of destroyed asteroids.
  • Randomize color of the ship.

Hope you like it!

please make better sprites for me if you want mine are garbage

Changelog:
changed quite a few attacks
reduced token count by a lot
made cherry soda work

prevents attacks from happening twice in a row
gaster blasters spawn cooler
you actually stand on platforms and don't just fall in place
some bugfixes. don't ask me what i don't remember

Hello, I am trying to pass my player.score variable (an int from 0 to wherever), using GPIO.

I have been using poke2(location, player.score) and then reading to the browser using pico8-gpio-listener.js library by Ben Wiley.

However, my player.score maxes out at 255 and then resets to 0. This doesn't seem right so any help would be appreciated. The player.score itself goes as high as I need it to, it's just when I use poke2() it limits to 4bits(?) I think.
