Picotron "fetch" function incorrectly converts path to lowercase

Sun, 07 Apr 2024 06:46:10 UTC

Picotron will convert all path/url strings to lowercase, invalidating some URLs.
I've uploaded a few small files (lowercase_file.txt, UPPERCASE_file.txt and incorrect_case.txt) to showcase this

function _init()
    --will try to fetch "lowercase_file.txt"
    lower = fetch("https://www.lexaloffle.com/bbs/files/51368/lowercase_file.txt")
    --will try to fetch "uppercase_file.txt"
    upper = fetch("https://www.lexaloffle.com/bbs/files/51368/UPPERCASE_file.txt")
    --will try to fetch "incorrect_case.txt"
    wrong = fetch("https://www.lexaloffle.com/bbs/files/51368/INCORRECT_case.txt")
end

function _draw()
    cls()
    ?lower.."\n\n" --should succeed, succeeds
    ?upper.."\n\n" --should succeed, fails (notice how error specifies a request to "uppercase_file.txt")
    ?wrong.."\n\n" --should fail, succeeds
end

this issue has been addressed in the future 0.1.0f update

Look at those cute little fluffballs, I sure hope they don't explode into a huge display of colours!

Chuzzles are very peaceful creatures, however, their friendliness can be their biggest downfall. If they are with a group of 3 or more friends of the same colour, they will explode into a cloud of fur.

Distance Formula for long distances

Mon, 17 Oct 2022 22:12:56 UTC

This function allows the calculation of the distance between two points without squaring the numbers, greatly increasing the max distance before the number overflows.

function calc_dist(x1,y1,x2,y2)
    local xdif=x1-x2
    local ydif=y1-y2

    local atan=atan2(xdif,ydif)

    local xdist=cos(atan)*xdif
    local ydist=sin(atan)*ydif

    return xdist+ydist
end

it is also quite fast, doing 5000 calculations per frame (which is way more than you will ever need) uses around 0.63 CPU

The long-awaited spinoff to Chess is finally here! In Adelie, your goal is to destroy all of your opponent's eggs while keeping your eggs protected. Every penguin has a unique move set, and can even be evolved to gain different moves and abilities! Below is an image containing each penguin's move set and evolution path for your convenience.

Each penguin may move using the arrows indicated by the green box and may kill using the arrows indicated by the red box.
The distance each arrow goes is important! All moves have a limited range matching that in the image.
Evolve a penguin by moving it onto the same tile as an identical penguin. Evolving an Egguin allows you to choose one of the three evolution paths.
If an arrow is facing down and has a small shadow, this indicates that the move cannot be blocked by other pieces along the path.
The Pengineer has a special ability that makes its attacks ranged, allowing it to kill other pieces without moving, as long as it has a line of sight.
The Flying Penguins divebombs create a devastating shockwave. Opponents pieces on a tile marked with an X will be killed if the Flying Penguin lands directly next to them.
The color of the cursor indicates which players move it currently is!

This cart will more than likely be no longer updated, as I will be doing a complete rewrite of the underlying system, although this may take a while

[Feature Request] Sprite Rotation

Wed, 11 Aug 2021 22:54:46 UTC

I think rotation would be a nice addition, even if it is only in 4 directions. Possible syntax:

-- draw sprite 1 at (60, 60), rotated 90 degrees clockwise 
spr(1, 60, 60, 1)

-- draw sprite 1 at (60, 60), rotated 180 degrees (effectively equivalent to flipping is both directions)
spr(1, 60, 60, 2)

-- draw a 2x2 sprite starting from sprite 1 at (60, 60), rotated 90 degrees counterclockwise 
spr(1, 60, 60, 2, 2, 3)

Syntax with rotation mode as the last argument could work similar to 'print' in the way that print reads the second argument as the color if not enough arguments are given
