Hold (O) to see the cycle of life.
TO LOAD THIS CART in immediate mode type:
load #hg |
While the cart I'm working on now (and have been for several days) is quite a bit bigger than 560-bytes (hundreds of lines), seeing Conway's life program reiterated reminded me of my Father.
For years ago he wrote a program in Turbo Pascal he called the "Cycle Of Life."
In it, he had 3-different colored pixels randomly appearing on the screen in a 640x480 screen.
He told me that one pixel chases the other and the last chases the first. I really didn't understand him so he explained it to me.

Hey everyone! In case you haven't heard, we're holding the third TweetTweetJam over on itch, and it started today. Make a game in 560 characters or less, without using sprites!
There's already a ton of participation, and it's always a very fun time, so I hope to see some of you come out! If you make anything, make sure to drop a gif on Twitter and tag it #TweetTweetJam so everybody can see your work. :)

The layout of the clickable buttons (fullscreen, control help, mute, etc.) on the side in the 0.1.12c version of HTML exports appears to have broken in Google Chrome all of the sudden. All of the buttons now appear stacked on top of each other :\
screenshot:
The layout still works in Firefox. I guess Chrome recently changed their interpretation of CSS rules in a way that broke this?

For some reason I felt like writing a little immediate-mode GUI library.
It has:
- Labels
- Buttons
- Check boxes
- Radio buttons
- Sliders
- Text boxes
You write into the text boxes on a little popup keyboard.
It works best with the mouse, but it can run in controller-only mode, where you move the pointer around with the direction arrows (it's pretty cumbersome though).
"Immediate mode" means you call the functions to draw the widgets in your drawing code, and it returns the user's input. It's generally easier to integrate into projects than a traditional widget UI would be, as you don't have to create and manage objects, you just draw the UI controls you need where and when you need them.

Endless Underground Snake 2.5.D
Endless Underground Snake is online!
I've made some great changes to the game, including endless gameplay with hundreds of different, procedurally generated levels, an ability to dig underground, a tutorial intro screen as well as a mini-map. For future updates I plan to fill those rooms with new creatures and paths.
If you want to skip the intro screen hit Y/Z
I hope you enjoy!
Updates:

This is a quick port of my PICO-8 boids cart. Nothing fancy, just some boids doing their thing.

Doppelganger
By Frelon-K Games
"I hate you,
you're my worst enemy...
But if you die,
I also die..."
Left / right to move your characters.
Z to (re)start the game.
My first Pico-8 project! (Yay!)
Hello,
This is the first game I create with Pico-8...
Doppelganger, a classic avoider where you control two characters.
When the first one goes left, the second one goes right.
Avoid everything and survive as long as you can!
Hey, by the way !
In the beginning, it was an Unity project, but I thought it has a better place here! Ha, ha!
I made this game in only one day and it might me improved!

Did a really simple snake game during Saturday night :) haven't figured out how to properly increase the speed of the game so help with that and feedback is vert much appreciated.
Edit:
Added particles screen shake high score and difficulty selector

Revised 2020-01-17 to use and describe pal() commands instead of poke() commands.
One of the things that's been very much on my mind as I've been learning PICO-8 and making my first full game project in it has been how to use the console's limited palette, and particularly how to ensure that everything I put on screen is clear and straightforward to read. It is very easy when designing user interfaces to make something that looks fine in a screenshot viewed in a well-lit room on a bright monitor by someone who knows where and what everything is, but obscure or confusing in actual play under the varied conditions which your audience plays in.
Nothing substitutes for testing, but the number one idea that I've used to try to make sure I start with something easily-read or close to it is contrast ratios - essentially, how much difference in brightness there is between two colors.

Berry The Scientist is alternative version of my entry to #ProcJam "Terry The Skeleton" that I submitted couple of days ago. The idea was suggested by @dw817 and ( @mtrc)[https://twitter.com/mtrc]. In Berry, the player can move up to three moves before the enemies can move. The goal is to see how fast you can finish the game in number of enemy steps. I hope it make you smile while playing :)
Controls:
- Arrows: to move/dash around based on the movement type
- X or Z: to change the movement type between normal movement (1 tile move) or dashing (tile it reach a wall)

I've been wanting to do this for a while. This is a simple boids simulation. Most of the code was adapted from Daniel Shiffman's implementation in Processing.
Feel free to pick apart the code. Unfortunately, it's not commented much, and I'm absolutely sure there are optimizations that can be done.

Old project (it was a small project to learn lua and pico8), was "in-progress" figured I should upload the final version.

[128x128] |
You may have seen a few carts show impossible logos both in the BBS and in Splore. Impossible in the fact that you scan both code and memory to see where the logo is but it's nowhere to be found.
So - just how did they get that logo on there in the first place ?
Well, with a little bit of trickery, actually. You can do the same thing in truth.
Load up your cart. In immediate mode type:
export spr.png |
to export your tiles to a temporary file.
Then type:
import logo.png |
The 128x128 logo that you want.
At the bottom of your code or the first lines in _init() add:
memcpy(24576,0,8192) repeat until forever |

"Tweetcart" which plays Piano Phase by the composer Steve Reich. The music is generated and played in the space of 280 characters (one tweet)!
Here's the code:
n="46bde64db6ed"d=#n
j=12800
o={0,0}for i=0,31 do for e=0,1 do
poke2(j+i*2+544+68*e,21120+i+e*64) end end
g=0
function _update60()for i=1,d do
g+=1
for e=1,2 do
if g%(90-e)<1then
w=o[e]
o[e]=w%d+1
sfx(7+e,e,tonum("0x0"..sub(n,w,w)))end
end
end
print("steve reich-piano phase")

This tutorial is part 3 of a series. View part 1 here.
And the end of part 2 we had roadside objects drawn using scaled sprites and sections of the map.
Everything so far has been flat, so in this tutorial we will add some hills and valleys.
This will require solving some overlap issues which we will solve using a clip rectangle "trick", which will in turn set us up nicely for implementing tunnels - so we'll do that too.
Defining the pitch
First we'll define the pitch of each corner with a field called "pi" (not to be mistaken for the Greek letter and mathematical constant).

I made some fruits for pico-8. Feel free to use it, but please mention my name (gwalker76 or 8x8Studio) in your game. Thanks :)

Edit: Never mind, I think the sound driver on my system has some kind of volume compression enabled.
There seems to be something amiss with the SFX player code.
The cart below simply plays a single SFX. The SFX is a constant sine wave tone with a stepped volume envelope. The envelope steps up each half second, from 0 to 7, and then back down each half second, to 0.
On my PC, this results in the SFX immediately being nearly full volume, stepping up once, maybe twice, until it's actually full volume, and then remaining full volume almost until the end, when it then steps back down four times to medium volume and then abruptly turns off.
On the web player, it seems to be more symmetrical. I'm hearing it start at medium volume and step up four, maybe five times before holding steady for a while and then stepping back down four times to medium volume and abruptly turning off.

Terry The Skeleton is my entry to #ProcJam that is happening on itch.io where you have to design a game/tool/anything that uses procedural generation or as they say on the website create something that creates something else. In Terry, the player can moves in realtime while enemies are still restricted to be in turned-based. The goal is to see how fast you can finish the game in number of enemy steps. Terry is a silly little game with a silly funny story, that I hope it make you smile while playing :)
