Hey there I was playing trying to recreate the Unknown Pleasures cover art, and this is the result if you've ever done it before I would love to see how did you solve it.

Cheers!!

def lsPts(num):
    points = []
    m = side*0.3
    for i in range(0, side, 12):
        if i <= side*0.2:
            x = i
            y = sin((i*(randint(1, 3))))
            points.append((x, y))
        if i > side*0.2 and i <= side*0.4:
            x = i
            y = i*sin(radians(i*(randint(-100, 100))))/(10**1)
            if y < 0:
                points.append((x, y * -1))
            else:
                points.append((x, y))
        if i > side*0.4 and i <= side*0.6:
            x = i

            if y < 0:
                points.append((x, y * -1))
            else:
                points.append((x, y))
            m -= 1
        if i > side*0.6 and i <= side*0.8:
            x = i
            y = sin((i*(randint(1, 3))))
            points.append((x, y))

    for j in range(steps):
        newPage(side, side)
        fill(0)
        rect(0, 0, side, side)
        m = 0
        for i in range(int(side*0.8/13.5)):

            stroke(1)
            strokeWidth(1)
            path = BezierPath()
            with savedState():
                translate(side*0.1, side*0.1 + m)
                path.moveTo((0, 0))
                path.curveTo(*points)
                drawPath(path)
            m += 13.5

    lineGrid(i)

I'm looking for a property to work with textBox() to align the text to the vertical center. What I'm imagining is something like this:

textBox(
    'DrawBot is great',
    (
        width()*0.2,
        height()*0.2,
        width()*0.6,
        height()*0.6
    ),
    align = 'center',
    verticalAlign = 'center'
)

This way you can come up with a random playing with that verticalAlign or something like that

Thanks Frederik you've helped me a lot!!!

@eduairet I tried this and now opens the script and it's not giving me errors but it still doesn't run entirely:

openWindows = Quartz.CGWindowListCopyWindowInfo(
    Quartz.kCGWindowListOptionOnScreenOnly | Quartz.kCGWindowListExcludeDesktopElements, Quartz.kCGNullWindowID
)
openWindows = [window.get('kCGWindowName', u'Unknown').encode('ascii','ignore') for window in openWindows if window['kCGWindowOwnerName'] == 'DrawBot']
if b'main.py' not in openWindows:
    os.system(f'open -a DrawBot {__file__}')

Debugger shows the problem now:

Traceback (most recent call last):
  File "main.py", line 45, in <module>
  File "drawBot/drawBotDrawingTools.pyc", line 2548, in Variable
drawBot.misc.DrawBotError: There is no document open

It works if I run main.py does it need to open a window first and then run Variable?

@frederik thanks!!! I just got curious about it. I'm having a problem with the package, it doesn't open the script when I open it in DrawBot, this is the tree I have

myPackage.drawbot
├── info.plist
└── lib
    ├── squareAdjustments.py
    ├── logoAdjustments.py
    ├── fontAdjustments.py
    ├── userText.py
    ├── main.py
    ├── resources
    │   └── fonts
    │       ├── VF.ttf
    │       └── Logo.otf
    └── save.py

When I open main by itself it runs

Is there a way to execute the Run command using shell or applescript?

@frederik sweet, I’ll give the package a try, I thought about using the app because it needs to be an executable and avoid the run part of the workflow.

Hey there!

I'm attempting to make a standalone app with a drawbot script using py2app and drawBot as a module. I'm having a lot of trouble with the Variable menu, the error I'm having so far is raise DrawBotError("There is no document open") when the script gets to Variable(menuElements, globals()) I'm speculating about how to solve it, Do I need to assign a document to the class or something like that?

@monomonnik Wow! This is beautiful, thanks for taking your time making an approach, and also for sharing it. It makes sense how you solve it and gives me more ideas to make more challenges like this!

Hi everyone, I'm putting some effort making basic exercises more challenging, right now I'm struggling with a chess board, I usually solve this with two loops and conditionals, but my challenge is to do it in one loop and with no conditionals, here is what I've done so far:

side = 800
newPage(side, side)
square = side//8
with savedState(): fill(1), rect(0, 0, side, side)
y, advance = 0, 0
while y < side:
    rect(square * (advance%2), y, square, square)
    rect(square * (advance%2) + square*2, y, square, square)
    rect(square * (advance%2) + square*4, y, square, square)
    rect(square * (advance%2) + square*6, y, square, square)
    y += square
    advance += 1

Do you have any smarter idea to solve this coding challenge?
Thanks!

@frederik thank you very much! I'll implement this way
