    • RE: Free "Runtime" App?

      Well, there is the app template.
      You will need a Mac and an Apple developer account as well as xcode, but this allows you to package your Pythonista scripts in their own apps.

    • RE: How to load a custom scene Texture?

      My current approach is to load the tileset.png which contains all the tiles. I then use Image.crop() for every tile I want to extract. I then upscale them using Image.resize() by some arbitrary factor, because if I would let the scene upscale the 8x8 textures to something like 64x64, the performance drops hard. Using BytesIO I convert them to ui.Image without saving them on disk and from there I can load them as a scene.Texture.

      But thank you for the hint that I can load the image and scale them in one operation!

      All I had to do to fix the original problem was converting the tileset.png to RGB mode.

      @Webmaster4o I should have put a smiley at the end of that, I just couldn't resist to be the stereotypical un-fun German :P I know that you were just kindly poiting out a mistake :)

      Now to turn this into a steganography module ;)

      Who needs base64 encoded images when you can have this?

      I'm not very active at posting here, but a very interested reader, so I have found the notifications as my main way of browsing this forum for some time now.

    • RE: console autocomplete bug

      Also in normal editor. If a word is fully written out and you use tab-autocomplete, the word will be doubled.

      math --TAB--> mathmath

    • RE: Using NSNotificationCenter help

      NSNotificationCenter isnt not related at all to the UI-Notification-Center. NSNotificationCenter is some kind of async messaging system. You can register a function to be called when a certain message is sent in your program, somewhat similar to a delegate.

    • RE: How to load a custom scene Texture?

      I found the problem: The images I used For testing where saved in P / Indexed Color mode. This can be checked with PIL

      from PIL import Image
      
      img = Image.open('sprite.png')
      print(img.mode)
      #> 'P'
      

      I converted them with img = img.convert('RGB') and saved them again. Now it works. It seems that the Texture class cannot handle files in mode P and does not fail gracefully. This is probably an oversight.
      Thank you again @cvp for taking your time to help! Much appreciated.

    • RE: How to load a custom scene Texture?

      I now imported a photo I took with the iPad (JPG) via the little plus in the bottom left -> Import... -> Photo Library and it worked fine!

      Maybe there is a problem using PNGs?

    • RE: How to load a custom scene Texture?

      After testing with a bigger image (overworld_tileset.png, 565x564 px, 44kb) I got the same result.
      Restarting Pythonista did not help, restarting the iPad did not help.

    • RE: How to load a custom scene Texture?

      Thanks for the suggestion, but the image is in the same directory. It is really odd that it does work for you, but not for me.

      I am on iOS 13.5 (17F75) with an iPad 7 and Pythonista 3.3 (330025)

    • How to load a custom scene Texture?

      Hi, I am trying to build a scene with custom textures, which I pre-process using PIL. From PIL I then convert them to ui.Image and then I want to load them as a Texture. Unfortunately, I cannot get them to load at all. Included is a minimum (non-) working example with a normal png in my project directory.

      import ui, scene
      
      image = ui.Image('sprite.png')
      image.show()	# this works
      texture = scene.Texture(image) # this fails
      '''
      Traceback (most recent call last):
        File "/private/var/mobile/Containers/Shared/AppGroup/73760516-2464-4322-8DCC-0525D46DFFC3/Pythonista3/Documents/smw/minimal_example.py", line 5, in <module>
          texture = scene.Texture(image)
      ValueError: Could not load image
      '''
      
      texture = scene.Texture('sprite.png') # this fails as well
      '''
      Traceback (most recent call last):
        File "/private/var/mobile/Containers/Shared/AppGroup/73760516-2464-4322-8DCC-0525D46DFFC3/Pythonista3/Documents/smw/minimal_example.py", line 6, in <module>
          texture = scene.Texture('sprite.png')
      ValueError: Image not found
      '''
      

      The sprite.png is a 32x32 PNG with a size of 981 bytes. I had no luck getting this to work with other images so far.
      Any help is appreciated.

    • RE: Pythonista 3 Beta 9 Crash

      @disorientedp Yep, because of the jailbreak I'm staying on iOS 8 for now. But I will upgrade to iOS 9, if/when Pythonista stops supporting iOS 8, just like @JonB :P

      @omz It seems to be working fine now, at least it doesn't crash when typing. If something else occurs, I'll let you know!

    • Pythonista 3 Beta 9 Crash

      Whenever I try to write a file, as soon as I input any character via the onscreen keyboard, Pythonista crashes. I have not tested it with a bluetooth keyboard, but I assume it has to do with the autocompletion. In the console it works fine.

      I am on an iPad mini 2 (I think it is model number is 4,4) with iOS 8.3. Also I should add that I am jailbroken.

    • RE: Performance

      The speed of Python lies mostly in development time. Python is not the fastest language execution wise, but getting something running is A LOT faster than in comparison to C or Java.

    • RE: Python 3.x Progress Update

      One bug I noticed is that when you press Tab in the console it will be converted to soaces, regardless of the 'soft-tabs' option.
