NOTE: the audio recording appears to have periodic jitter. As I recorded at 44.1 Khz this time, I wonder if my S2 just handles recording at a lower quality better, and if so I'll prefer lower quality over jitter in the recording.

In this episode I explain why and how I abstracted random number and choice generation into self-sustainable methods for objects.

  • A superclass was needed so that all the classes of object in the game engine would have access to these random generation methods.
  • I preferred to use methods in this case so objects would be self-sufficient and wouldn't depend on extra modules imported at the top of my code.
  • The syntactic sugar achieved by using customized methods instead of i.e. random.randint(0, 99) makes the code easier to write and understand at a glance.
  • Nurse Jesus is a pun on the acronym RNG for Random Number Generator
  • Let me know if you get the reference at 2:00 ;-)

I recorded this episode in parts using a program called Urecord on my pocket computer (mobile phone).

I program using Pygame, post on a GNU Social account, and maintain a personal website at NoxBanners.NET. I study programming techniques at, style at, and sometimes patterns at Portland Pattern Repository
