David's Super Nifty Secret Decoder Ring!
Wow ! Do they not at all make it easy to do what should be some simple string manipulation here !
what's going on ?
more work than I had hoped for lemme tell ya. however, it works, it's perfect and I doubt very seriously anyone worth their salt can crack the code to an encrypted message from this particular program as it uses random seed to build with.
That sorta thing is really difficult to reverse-engineer but - stranger things have happened.
Don't bank all your jewels on this, but I think it's a good encryptor for when we start to write those cool text adventures.
No sense in giving up the whole story by snooping eyes in your source code. :)
They used a simpler method similar to this when you would type out a text adventure from a book so as not to give the whole plot away as you enter it in.
Pretty sure these routines will be useful to you and others.
Questions, Compliments, or Kerosene, take your pick and stick it below. Send me some stars too maybe ? :)

Sometimes, your game makes use of a randomly generated sequence, but it would be nice to smooth out some of the short-term variance in it (e.g. long stretches of not getting a long piece in Tetris). This cart showcases some algorithms you can use to generate smoother-feeling random sequences, and lets you visualize them for tetrominoes, digits, or dice rolls.
Thanks to TetrisConcept without whom I would never have learned about these techniques, and to the developers who invented them.
See the code comments for more on the implementation of each randomizer.

My first Pico-8 game...
I wanted to make an old-fashioned arcade shooter, like Defender but not as difficult to play.
The end result differs quite a bit from Defender - except for its difficulty level. ;)
Tip 1: Completely wipe out a cluster of aliens and you'll earn an extra life. Survival means earning lives faster than you lose them (and you will lose them very fast).
Tip 2: If you already have three lives, an extra life will power up your smartbomb meter instead. When it's full - BOOM! Humanity's future depends on you triggering as many smartbombs as you can.
Tip 3: Those speedy pink loner aliens? Hunt them down! They're the last of their cluster, so that's where your extra lives/smartbombs come from.

A platformer example, from GameMaker to PICO-8.
I didn't know that cartridge image displayed your first 2 lines of comments.
Feel free to use this.
Press Z to jump and use arrow keys to move your player.

This game is based on the 1986 Intellivision classic Thunder Castle. It has dragons, and... dragons! So far only level 1 is (basically) complete, and there are 3 map variations that are chosen at random on startup. Eventually it will have a title screen as well as 2 more levels (I believe you can get to level 2 currently, but it's totally incomplete, doesn't have the right enemies or powerups or the second and third map variations). Level 2 will have 2 wizard enemies instead of the dragon, and level 3 will have 3 demon enemies.
Press action/fire to use items you pick up. Avoid the comb. A couple items don't have their functionality yet. Get the bat to become invincible for a short time in order to slay the dragon!
Credit to @solar for the excellent sounds and music!

I put together a page for my favorite PICO-8 games, and figured you'd all enjoy it! https://www.playpico.com/. At the time of this posting, there are currently 113 games - let's see how it grows!
Big update Jul 27th, 2017
The website has been completely rebuilt from scratch. I'm still working on some more features for it, but it's at a point now where I wanted to push the progress live. It's now built on top of my PHP MVC framework, Lightning, available here: https://github.com/clowerweb/Lightning.
- UI facelift. It's still fairly similar to the old UI, but has many improvements in both aesthetics and usability.
- Better performance; it should be snappier than ever now.
- Featured games! The front page is now a list of 24 featured games, chosen randomly each week. You can still go to the full games list by clicking "All Games" in the navigation, but this is no longer the index page.

Finally hit the milestone in Picoder development where I'm able to decode p8.png files in pure JavaScript. I couldn't have done it without the help of @gamax92 and @dddaaannn, as well as the source code of their respective projects PICOLOVE and PicoTool. It's been a long, bumpy ride, but here it is: http://clowerweb.com/picoder-test/. This will be used to import .png files into Picoder, and the decoding algorithms reversed in order to compile code (edited in Picoder's online IDE) to be playable in the web player for testing.
So huge shoutout and thanks to the above named! Hopefully the IDE itself will be available for public testing soon. Please let me know if you find any issues with the decoder - this is my chance to let you all test it and help me find bugs. Thanks!

I always liked Kohonen Networks. They're simple and fun. This is a simple 9x9 2D-to-2D Kohonen network with constant neighborhood function, trying to adjust itself to the purple training set.
Use LEFT/RIGHT to switch between training sets.
Use Z to reset the network.
Yay for machine learning on PICO-8!

Decided to remake an old classic, Pong! I know this has been done a million times before but I thought I'd give it a shot and maybe learn a thing or two.
Move left and right and smack the ball to the other side to score!
Known Bugs:
-Ball sometimes passes through the paddle when hit at the corners of the screen
-Menu graphics glitching slightly when selecting options
Controls:
Player 1:
Arrow Keys
Player 2
E,S,D,F
Version 1.1:
Added in simple AI for playing single player and now the first player to 5 points wins!
Version 1.0:

--[[ TAME CAT BATTLE ]]--
(also mostly known as rock, paper, scissors..)
This is a little game I made as an example of how to implement a high score system. It saves the player name, along with their high score into persistent cartridge data. It is based on my cat, who has frequent battles with our neighbours cat. I have however, toned down the violence significantly, to make the game accessible for all.
Go check out my project called PicoBoard to learn how to implement a high score into your game, or leave a comment!
Would love to see who could get the highest score, of this game of complete chance and endurance..!

Well hello there ! I bet you thought I fell in an open manhole or something. No such luck !
As it is, I want to share with you a lovely routine I have always written called TRX, which stands for Transmission X.
The term "Transmission X" comes from many years ago when i saw a B&W episode of Flash Gordon starring Buster Crabbe.
In one episode he mentions to Dale (his sweetheart) that he was going to send a "Transmission X" to an alien planet - and the music took a serious tone after he said this.
Dale asked innocently enough, "What does the X stand for ?"
Buster gave her a funny look. It was almost as if she forgot her lines or was ad-libbing, but he quickly responded to her,
"It means everything."
And that seemed to satisfy her. Or so it seemed. Since that time, the term and his definition of it stuck with me. "Transmission X." "it can do everything."
Later when I got into busy programming, i thought - why not make a routine, my own special "Transmission X" that does, well, just as Flash Gordon said, pretty well everything?
And I did, later shortening the name from "Transmit-X" to TRX.
There were a few other names I gave it. TR8, for instance, where everything was 8x8 pixels, but TRX I like that name the most and is what I use now.
And what YOU have here is a routine I oft write in any programming language I start out in when I want a strong text and image handler that works entirely and only with strings.
Full instructions are included. Lots of carrots. :)
I hope you find it useful for your own code and programs, and if you have some suggestions on what you'd like to see added to it, lemme know. If I can find my way around it, I'll do it for ya.

I am going to throw together a last minute entry for the Game Boy Jam (https://itch.io/jam/gbjam-5). I just started tonight, and the deadline is end of this weekend (Oct 9th, 2016), so this will likely be a pretty rushed entry.
I'm a programmer, and I would love to work together with an artist and sound designer if possible to help add some visual polish.
If you are interested please post some links to you work; preferably completed projects.
GAME IDEA
Wave Race Legend
2D jet ski game where you bounce off waves trying to take down AI opponents. A mix of Joust and Wave Race 64.
For simplicity there will likely be no "race" aspect to the game; just survive as long as possible.
As I mentioned, I just started this project, but here is a quick gif of my current progress to hopefully give you an idea of what I mean:

PICO-8 0.1.9b builds are now live on Lexaloffle and Humble.
This is a bug-fixing update, mostly for crashes related to switching between widowed mode, full-screen and minimized windows. I've also included the dynamically linked pico8_dyn versions in the linux archives, that were missing from 0.1.9.
The Windows installer & .zip file include a more recent sdl2.dll, although there weren't any known issues relating to that.
I've switched back to shift-a..z for glyph entry in the code editor, as alt-a..z is sometimes reserved by the host operating system. If you find yourself accidentally entering the extended characters by accident, you can turn this off in config.txt (near the bottom). To enter glyphs without shift-a..z, press ctrl-k to toggle glyph mode.
Changelog:
v0.1.9b Added: Alternative function key mapping: ctrl-6..9 for F6..F9 Added: Alternative glyph entry method: (ctrl-k) to toggle glyph mode Changed: Enter glyphs with shift a..z, but can be disabled in config.txt Changed: Increased emscripten ram to 128MB (some carts at risk of running out) Fixed: Crash when window size is tiny or minified Fixed: Crash on toggling fullscreen mode Fixed: printh can write files outside filetree (security issue) Fixed: show_fps (can also now be toggled with ctrl-1) Fixed: Shorthand if/then syntax error when using the form: (functionname)(param) Fixed: log.txt not saved in path specified by -home switch Fixed: Default application data folder created even when -home specified Fixed: Missing dynamic builds (pico8_dyn) from linux archives Fixed: Removed unneeded RPATH from linux binaries Fixed: export foo%d.wav fails to write multiple files |
