A quick google search found me this:
Detection between a circle and a line

Should be a good start.

@ccc It looks nice. Just checking to see that I've understood this... It is a way to check out the files from a git repo into Pythonista. And Working Copy itself can keep the files in sync between iOS devices. But getting changes of the files out of Pythonista is not covered by this solution. Do you copy-paste the changes into Working Copy manually?

How do you use it yourself?

I was wondering about the current state of OpenGL/GLES/GLKit support for Pythonista (3). Between numpy and objc_util I guess the possibilities are there.

@bennr01 Thanks for the clarification and the links. It is unfortunate that syncing between your own devices can't be built in because of this.

I'm not sure that a built in Dropbox sync feature would not be allowed by Apple. If Editorial already syncs scripts it seems ok. Apple is trying to prevent people from building app stores in apps as well as trying to protect people from running potentially bad programs.

I understand why the "Open in.." feature was not allowed by Apple considering their policies, but that is a different thing.

Syncing your own Python programs between your devices with Dropbox might not be a problem.

I was wondering the exact same thing as @Omega0 did two years ago. Since the documentation has not yet been updated it's great to have this forum and that it is easy to search.

Not only is Pythonista amazing, the level of support is equally crazy! Thank you @omz.

ObjC is nifty for all sorts of things.

I've looked but I can't find anything about this. Does anyone know if there is a way to disable the on screen printing in a Scene/SceneView?

I'm referring to this: For debugging purposes, a SceneView will show standard output and exceptions in a “status line” at the bottom, so you can use print statements during development, even if your scene covers the whole screen.

(Actually this is only documented in SceneView, even though the feature is available when using Scene.run() to show a Scene. )

Sometimes printing stuff when running a script is useful, even when you don't want to see it directly on screen.

I don't know if it is related, but I am encountering a crash with a very similar piece of code, but not for code completion. This crashes when it is run:

# coding: utf-8

from scene import *
import sound
import random
import math
A = Action

class MyScene (Scene):
    def setup(self):
                #Does not crash 
        SpriteNode('emj:Airplane', position=self.size/2, parent=self)
                # Will crash
        SpriteNode('iow:alert_256', position=self.size/2, parent=self)

if __name__ == '__main__':
    run(MyScene(), show_fps=False)

It's always crashing for me on Python 2.1, but not on Python 3.0. I assumed it had to do with some of the built-in image collections somehow.

On the donation/financial contribution topic. I can understand that @omz feels uncomfortable taking donations, this brings notions of charity. But me and many other are more than willing to contribute financially to the apps, to show appreciation for this wonderful tool and to help with/speed up future development. If there would be an anti-sale day for the new Python 3 version with a higher price (5x?) I would buy it that day.
