Re: [pygame] Is it safe to subclass Pygame Channels and Sound classes?



Thanks Lenard,

I learned that today when I tried to subclass pygame.mixer.Channel and it didn't work and error said I was trying to subclass a method and not a class. :)

No need to change this on my behalf. As I wrote, my current implementation is to have my own separate class which just references the related pygame Channel object. So that's fine for me.

Thanks again,
Brian

Sprites are a little different. They are Python classes, while Sound and Channel are extension types coded directly in C. pygame.mixer.Sound is an actual class object, and can be subclassed. mixer.Channel is just a function that returns a new Channel instance. The actual Channel type has not been updated to support subclassing. If subclassing Channel is a desired feature, then I will fix the oversight.

That's normal. I usually subclass Sprites every time I use them. They even have methods set up that you are expected to override.

  Hi Everyone!

  In my app I'm making heavy use of Pygame mixer's Channels and
  Sound objects. In both cases I need to add additional methods and
  attributes to them. Is my code is now, I have my own classes of
  each which reference related Pygame classes. (In other words, my
  "Channel" class has a bunch of things like the name, the priority
  of the sound that's currently playing, a reference to the Pygame
  Channel object, etc.)

  My question is whether it's ok to subclass the actual Pygame mixer
  Channel and Sound classes for my use? I've never subclassed
  anything from an external module before, and I guess I'm wondering
  whether that's ok to do or whether that's frowned upon?

  Thanks in advance!
  Brian
