Firstly,

PLEASE DO NOT TRY THIS!!!

You may end up with files or folders that you cannot remove.

(I don't wanna be responsible for damages!)
Edit: It turns out there is a way to remove them, see below.

Illegal Names?

Not many people know this, but there are some folder or file names that Windows won't allow you to use. These include 'con', 'aux', 'nul', 'lpt0', and others. Seriously, if you're using Windows right now, make a new folder, and name it "con", it will tell you "The specified device name is invalid". (This is safe to try since the folder never actually gets renamed)

Through curiosity I discovered that PICO-8 completely ignores this rule and allows you to create folders or files with these names using the 'mkdir' and 'save' commands.

What's the problem?

Naming a folder 'con' seemed to have no issues other than refusing to be opened by the 'folder' command, however once I named a folder 'nul', it became impossible to remove. Windows prevents you from renaming or deleting it, so I now have a folder that I can move around, but not remove, rename, or open.

Enter a world of underwater caverns off the coast of an uninhabited island in my new PICO-8 metroidvania game, DIVER. Explore mysterious rooms and hidden passageways where you will come face-to-face with hungry aquatic creatures.

Note: This game is still somewhat in beta with a few minor bugs, but I may not go back to it anytime soon. It's fully playable til the end, just be resourceful with your ammunition!

Hello:

Instead of buying an RG-351 or other gaming device, I settled on purchasing a gaming controller called the RAZER KISHI that allows you to place your cellphone in the middle and you can use the joystick accordingly.

https://www.razer.com/mobile-controllers/razer-kishi/RZ06-03360100-R3M1

While it works perfectly everywhere else including emulation of other games like Super Nintendo and Sony Playstation for the RetroArch, it is not configured correctly for the Pico-8 system when run from Google Chrome.

For instance the BLUE does nothing at all. Instead arrow key controls are done by the RED sliding joystick above that.

In the GREEN, The (A) and (B) control the (A) and (B) for Pico-8 just fine. The (X) and (Y) also do (A) and (B) but not auto-fire.

May I suggest, @zep, that the [b]RED

Belt It Out POC

Here's a POC of a factory sim.

See 'Open Tutorial' in the game menu for details!

CONTROLS

• arrow keys
  • move cursor/eyeball monster
• O - (C on keyboard)
  • place selected object
• X + UP/DOWN
  • cycle through cursor modes
• X + LEFT/RIGHT
  • cycle through selected cursor options

Delete a building or belt by using the delete cursor mode.

Buildings and belts can be replaced by different buildings or belts. Belts can not be replaced by buildings or vice versa without first deleting the existing structure.

OBJECT OF THE GAME

Produce resources by placing production buildings. Conveyor belts can be used to move resources (and the eyeball monster) around.

I'm trying go back into my game Destructopillar to try add/remove some things but see I am at token limit. I've done some basic refactoring and stripping out unneeded functions that are now part of the core but it's not enough.

I was looking over the manual to see what functions are available now and was reminded about coroutines. The problem is, I never really understood how to apply coroutines. I get the concept and I think I understand the gains (like saving tokens), but just can't figure out where in the game it would benefit from coroutines, if at all.

Please check out the Destructopillar game below real quick, even just the first stage and you'll get the gist. Then please call out the places where you could see coroutines being useful.

I'm not looking for cart code analysis or digging into what's there right now. Just looking at the game on the surface...the actors, the actions, the scenes...would coroutines possibly make sense anywhere?

And the answer could really be they wouldn't help in this type of game. And that's okay...because I just don't know. I sense that coroutines could help and make things better and save me some token trouble but maybe not.

Ok, so I want to make a celeste mod but I dont know how, I tried using the Education Edition but it didnt save my progress and files are confusing. Where should I go to learn how to make a mod. FYI I am working on a school issued chromebook because I am still a highschool student, should I instead start working on my macbook at home?

any help is appreciated
Thank you :D

Diving WIP 0.1

--sx = x location of sprite on spritesheet
--sy = y location of sprite on spritesheet
--x = is this for the rotation area?
--y = is this for the rotation area?
a = angle of rotation
w = width of sprite (although mine is rectangular)
rspr(sx,sy,x,y,a,w)

Once I've got rotation sorted. I'm going to figure out number of turns and angle of the divers head relative to the water, so I can get the judges scoring in. I think my next big challenge will probably be getting the board to bend when hit.

Thanks for taking a look. Hopefully I can release something more playable soon.

Hello to anyone that sees this. I'm in the middle of working on a Pico 8 game, and it's turning out great so far, however I'm running low on graphics space and I need the whole map for the levels so I can't use the second half of the graphics space. If there's a way around this, perhaps a poke() function that I'm not aware of, or another method, and if someone could tell me that would be great! Thanks!

Hi,

I'm heavily using .p8 files as headless scripts to automate my export pipeline. It's great, as all commands are available and when running headlessly, you can even save/load which fail in normal GUI mode.

However, I noticed that errors are completely silent (unlike GUI mode, which shows error messages). How can I catch PICO-8 errors from within the .p8 script or, as last resort, from the bash script I'm using to pico8 -x the .p8 script?

The most commonly failing commands are save("game.p8.png") when the PNG is too big, and export("game.bin/html") where we're missing an icon or label. When that happens, I must re-run the commands in GUI mode and inspect every error one-by-one. Besides, the commands I manually type are generally slightly different from the script ones (which are very complete with all options) so I'm not exactly sure if I'm reproducing it right.

My suggestions:
a. access error code of last native PICO-8 command (like, save, load and export) with a simple function (e.g. err() which returns an int). We could go further by getting the error message too (e.g. errmsg())

This is part of a bigger project I've been working on for quite some time now. This pico8 game is a mini-game where the events depicted in it which will be accompanied by a comic book(WIP). The events present here on the game happens in the comic, some four pages of it. The project consists of several comic books, some games and a podcast. The whole thing revolves around a war, now cold, between a race known as Zeta Reticulans and a political group known as The Union for control over reality. It's also about Omnia, a company founded as a revenge plot by two genocide survivors that became the biggest conglomerate ever know.

Editing Infinite- If you find any cheesable parts, please tell me! I want the game to be as hard as possible :D

CHANGELOG
v2.1: Attempted to fix cheesing on lvl 2

v2: added new levels! WOOOO

Hey, if you're showing this to a friend, maybe have them play the original Celeste Classic first

Hi everyone
I've just dived into Pico8 and I'm so enjoying it that I cannot do anything else :-)
I've that small prototype but I've encountered a weird bug with sprite editor I don't know how to fix it.
Maybe you can help?
Here's the issue:

• When I modify some pixels on the sprite editor, it also modifies the map at some specific coordinates
• The opposite is also true: if I modify the map, the sprites are changed

  It's a bit complicated to go on my level design so if you can help solving that... I would really appreciate!
  Thank you and keep up

• Pierre G.

Been working on this one for a while! I consider this to be my first real finished game. Thank you to all. May this be a good omen to any future games I want to make!

Can you find all the codes, and use them?

Looks pretty bad online. Runs best offline.
