Bitdraw - Drawing tool in under 600 characters!

Sun, 05 Dec 2021 19:28:48 UTC

Heya! So, the new one-off character feature added in 0.2.4 inspired me to write a drawing tool that exported to compatible strings in the smallest size I could, as of now, the code itself is only 520 characters!
(Minor warning: clipboard saving seems to be incorrect through the html export, I recommend copying the code and running it locally)

end
goto _

Controls:

Left Click: Draws inside the white rectangle
Right Click: Erases pixels in the rectangle
❎: Copies your drawing to the clipboard alongside making a small noise to notify you

To then use your drawing, you need to use the \^. control code followed by your string:

print("\^.~▒しし▒し▥~") -- Prints a smiley block
?"\^.~▒しし▒し▥~" -- Short-hand version

Feel free to elaborate on this tool or minify the code even further!

P8SCII Bug - Dotty mode's "replaced"

Sun, 05 Dec 2021 17:52:19 UTC

Hi, so with the new Pico-8 update (0.2.4) I've been messing around with some of the new features and specially P8SCII, as of now I found something pretty weird, the new one-off character control code (\^.) seems to use the same control code as dotty mode used to, I noticed this when I ran the Impossible Mission cart, which has a corrupted title now due to Pico-8 treating most of the string as 1-bit character data.

I don't know if this is was done on purpose since it's still mentioned in the manual ALONGSIDE the new one off character control code, maybe Zep forgot it was already in use or he changed it to another control code without adding it to the manual? If this has been documented before or I'm doing something wrong please tell me.

Warp sprite functions!

Hi! I decided to try out recreating a effect used a lot during the snes-genesis era, a warping sprite effect, it uses a little bit more cpu than what sspr would use and it doesn't support flipping vertically due to how the code warps the sprite, it comes in both spr and sspr flavors for people who are used to either of them, enjoy!

Also big thanks to Merwok and FReDs72 for giving me feedback and tips on how to make the function faster

#Include from subfolders?

Sat, 27 Mar 2021 00:22:05 UTC

Hi, I'm trying to write a game in a very clean way instead of cramming multiple copies of the same code on multiple carts, most of this is solved with #include but for what I've tried, you can't do include from subfolders, what I mean is that for example, if I have a cart on a subfolder called "font" but wanna include functions from a cart located on the parent folder, something like
#include ../cart_with_functions.p8

won't work, is this even possible to do with include or am I just out of luck?

Small cheat code system

Hi! I wrote this little cheat code function and decided to share it here if anyone wants to put cheat codes on their games, here's how it works:

paste all code labeled as requiered onto your cart, this includes:

chsys={}
all code on the _update function
the add_chsys function

then, to call a cheat code, write it down on a table like this:
konami_code={⬆️,⬆️,⬇️,⬇️,⬅️,➡️,⬅️,➡️}

and then call the add_chsys function once (if you call it on an update function/every frame you'll chug the system):
add_chsys(name_of_your_cheatcode_table,function_to_load_if_it_succeeds)

So for example if I wanted to make the game stop when the Konami code was detected then I'd put this on my _init function (or any function that only acts once):
add_chsys(konami_code,stop)

Hope ya enjoy!

Trouble with C64 mini controller on Raspberry Pi Pico-8

Tue, 12 Jan 2021 22:06:43 UTC

Heya uh, just bought a Pico-8 license over on itch a few hours ago and I've been trying to get it to run on my Raspberry Pi 3 b, followed a tutorial on getting it to work on a fresh install of Raspbian and it works great, the problem now is that I wanna use my C64 mini joystick (Which is pretty much THE perfect controller for the system, two buttons, joystick and plenty extra buttons for settings), I got it to work on linux by making a configuration for it with the SDL2 Gamepad Tool and putting that on the sdl controllers file in configs, but making the same in my Rpi did uh, nothing, if anyone can help out with this it'd be amazing, thanks.
