Sometimes it can be tricky to get the computer to do exactly what you want, and it's a great victory when things finally work. It's tempting to move on to the next task at hand, but often it's better to look back and improve some things.

In this episode Sybren shows some techniques to reorganise code, with the aim of improving the readability & understandability.

  • 00:00 Intro
  • 01:12 Investigating the Camera Background Image panel code
  • 02:31 Splitting the code that handles an image into a function
  • 05:30 A little analysis of the loop
  • 06:11 Splitting up the code further into functions
  • 07:44 The has_bg mystery and the final flattening
  • 13:55 Cognitive Complexity
  • 15:00 Conclusion

This video was made using Blender 3.0 alpha.

I followed along & edited the code in 3.0 Alpha ... It works perfectly (I back up the original ;0)...  I'v gotta say, that was the best python tutorial in refactoring I have ever see in two score years. Well played Dr. Stüvel.

I've just finished all 20 videos and I must say as someone who has been developing software professionally since 1973 this is the best introduction to a programming language for non-developers that I've ever seen. That alone is a difficult accomplishment but to also set the introduction in the context of a fairly complex domain, blender/bpy, is a serious achievement.  Well done.
