NOTE: the audio didn't cut together as smoothly as I remember from the first time, probably because I forgot to record at 44.1 KHz

In this episode I explain in broad terms how I programmed a game system to adjust its display resolution using three distinct modules operating individually and in concert.

  • The "metagame" (launcher) module accepts an argument describing the size of the window available for display
  • The "gameplay" module is informed of the space available as a 'window' into the game world and uses it for one thing or another
  • The "graphics" module opens a window at the specified size and modifies the graphical assets if needed

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

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