If I treat you with any brutal criticism (which, I try to keep reasonable, so sorry if I make a mistake): You're the one who's making the game. There might be a reason behind everything. Opinions are opinions.
Ultimately, it's your choice. PLEASE disregard me, if you want.
if there's something I forgot, let me know
No, you probably won't know what I forgot, but if something messes up, or something's really weird and confusing, let me know.
Cartridge
Code licensed under CC BY 4.0. Yeah, that's right, steal the freaking code!!!!!
About - MCT, Map Command Tool
This is a cartridge that can help fit large maps in an extremely small space via the use of two byte commands that fill in or remove large sections at a time.
It doesn't do so automatically, but you are given a little interface to do the work.
You can also edit the maker code itself to create extra commands (there's five dedicated 2 byte commands available, and you can probably go crazy with the alternate commands).
It's not a compression system like PX9, but it still puts large amounts of data in a smaller space.
Still, it might not be what you're looking for, as it requires you to simplify quite a lot of the data and (as of right now) costs about 500 tokens to implement (which is kind of a lot).
In return, theoretically, you get a significant savings in map space. The above gif's map is in 10% of the usual space. I have not tested this against any other compression system.
Just think really hard about what kind of maps you have before you pick a compression system.
I really want to work towards making it super editable & good for whatever, so if you have any suggestions, let me know!! Please!
Data to command table costs ~229 tokens
Unmodified commands to map costs ~263 tokens
Make sure you have a screens = {} declaration.
You can see an example implementation down below in the OTHER section!
Some limitations
- There are only 14 main commands, 15 usable alternate commands.
- Currently it only supports nibbles for each main command value. Thus it can really only support 16x16 maps.
- It can only use 63 tile values without adding an extra byte (though you can use commands A-E to add extra tiles).
- Fills only use one tile at a time.
- If two maps use the same screen space, that's on you, dingus.
- Binary export messes with commands if they have too much zero
- The cart doesn't use devkit keyboard.

How to Use
Download the cart and place tiles in the spritesheet representing tiles from your game. Run the cart. Start editing!
Use arrow keys to move.
O and X are modifiers, and holding them will change what your arrow keys do - X will change what part of the screen you work with, and O will let you change a specific value.
O is also used as the "accept" button.
You can export it at any time by going to the bottom bar, hitting EXPORT, and then selecting either binary or hex.
Hexadecimal prints something like hf037, and is safe to put in any text editor. Binary instead gives you one-byte characters, along the lines of bユs that are meant to be put in a PICO-8 string, can contain weird characters that could possibly mess with other text editors, and will break if you have a command with "zero parameters" (see Commands documentation).
After hitting O on an export type, hit CTRL-C up to 12 times (just in case) and paste it somewhere safe.
To import, copy the entirety of a map string, paste into the app up to 12 times (just in case), then hit IMPORT 3 or 4 times.
Documentation
Bars
Top Bar
Use left and right to change the screen.
O opens up the banner, where you can add and delete screens, or go to the map preview (which uses the bigmap space).
On the banner, hit O to perform the action selected and use arrows to change selection.
Deletion is an irreversible action. Be careful.
The bar also shows how many bytes the current screen uses.
Middle
Arrows change the selection. Holding O makes them change a value instead.
To add a new command, go to NEW, hold O, and use up/down to choose where to place the new command.
All commands are put in the map in order, starting with "G" (which can't be changed as that marks where a new map is).
On a null command, you can press left and then O to delete it.
Bottom Bar
When unselected, the bar shows the total bytes this set of screens is using, compared to how many bytes it would take up uncompressed. It also shows the compression rate.
When selected, a banner opens up allowing you to import and export the map. To use import, you have to paste while the cart is in focus.
Importing is an irreversible action. Make sure your data is backed up well.
Exporting opens up the export menu and lets you export to hex or binary. You have to press CTRL-C to copy once you hit O on an export option.
Commands
Normal command parameters are sorted COMMAND, X, Y, V
Binary Conditions
If a command does not follow these conditions, it will be changed or removed on binary export. If you wanna use a lot of zeroes, you need to use hex export.
For normal commands, Y or V must be non-zero.
For F0, you must have one non-zero value. THIS COMMAND WILL DEFAULT TO X=F and Y=F OTHERWISE
For F1, you must have one non-zero value.
For F2, X or Y must be non-zero, and V must be non-zero.

License
I created this so that I could compress my map data without having to put BY-NC-SA, a license I didn't want on a game I'm making. So I'm making all of this cartridge under a CC-BY license. That includes the map loading code, but all you have to do is put a -- by wish volo comment right before it and you'll be good.
I completely encourage you to do whatever the heck you want. That's what this is meant for.
Other
Yes, it works:
I think a good way to use the "tiles" in the cart is as representations - it doesn't have to look exactly as it does in the editor. You can make it look different during import, like changing a tile based on possible variations or whatever.
example: Tile 1, no matter what it is in the normal cart, represents all and any ground tiles of type X. When loading to map data, if it detects value 1, then it will pick a random tile from group X and draw it!
easy peasy.
You can put a PAL() call at the bottom of DRAW(), cause that's where the map preview code is, if you want to see a different palette to match what your tiles will actually look like.
If you don't use a specific command, feel free to comment it out.
If you stick to using only hex or binary, then you can cut a few extra tokens out of the functions.
at some point i need to add base 64
the only issue with base 64 is that it might actually cost more tokens to do so, but it'd save more space than hex

I found a minor (except that to me it's kinda major) bug concerning puny font.
It seems to only affect PICO-8 when loading or reloading - whenever I save in an external source and reload, or when I boot up the console, all the puny font disappears.
EDIT: Never mind, turns out it was that _ENV thing. Thanks zep lexaloffle!
Hello, I'm Wish Volo. I made a game about sorting orbs.
And it's in PICO-8!
old versions
Z/C/N/Tab/Lshift to swap / "yes"
X/V/M/Q/A to cancel combotimer / "no"
Enter pauses (you're gonna have to hold it to bring up the PICO-8 pause menu)
It's got four gamemodes!
- Infinite: sort forever
- Blitz: sort quickly for a high score in a short time
- Clear: get as many capsules cleared as quickly as you can
- Knockout: splitscreen multiplayer
It's also got 12 tracks of music (5 casual, 4 tense, 2 KO)!
It's also got a little bit of contrast assistance. It's there.
You can also change the combotimer length and the orbcount with no penalty :)
Oh, and it's on itch.io too. https://wish-volo.itch.io/orbsort
if you don't mind, check it out for a little bit!
last note: This version of the game is only on Lexaloffle / Splore. The A version is found only on itch.io. If either version is found anywhere else, it’s been copied. Have a nice day :)
What I'm trying to do is make a typewriter script, but when checking to see that the third line has less characters than the dialogue, I keep running into the same odd error. Is this not a string?
-- typewriter
dialogue = {d1={
l1="qwertyuiop",
l2="asdfghjkl",
l3="zxcvbnm"}}
c_text_1 = "."
c_text_2 = "."
c_text_3 = "."
c_dia = 1
function typewriter(string,wait)
if frame > wait and #c_text_3 != #tostr(dialogue[("d"..c_dia)[l3]]) then
sfx(0)
frame = 0
end
end |
So I'm working on another game
The previous ones I worked on were a little... I guess... too much for my current PICO-8 skill. This new one will not be as big as the others.
Guess I'm both worried about my skill and the amount of coding I'd need for it.
So I was working on the map in PICO-8 when I found some tiles I never placed, so I started erasing them. Later I saw a chunk of my spritesheet was erased, so I fixed that manually. Later the same thing happened and found that the tiles are related to the colors in the sprites. Why is this?
In ROBLOX I am also learning how to code, but one thing stands out that I feel should be necessary.
What is supposed to happen is that it runs:
function _init() cls() spr(192,20,20,4,4) wait(3) end |
But it errors with
"Runtime error line 4 tab 0
wait(3)
Attempt to call global 'wait' (a nil value)
In _init line 4 (tab 0)
At line 1 (tab 1)"
Is there a way to make the program wait a few seconds without taking too much space?
Thanks :)
