Seeing"Realtime FFT Graph of Audio WAV File or Microphone Input with Python..." on python.reddit.com reminded me of one I'd built in python with shoebot.
While it works OK, I feel like I'm missing a higher level audio library (especially having seen Minim, for C++ and Java).
When cairo 1.10 comes out we'll get a RecordingSurface so you can record commands and play them back to another surface, but how to do something similar now ?
Skip to the end if you just want the code, explanation of how I …
Often it's useful to be able to store up drawing commands so you can use them later somewhere else (or even just pass them to another thread).

Using Processing from Jython is a promising idea, so I took the base from this post on backspaces.net where they explained how …
Cairo is a 2D vector graphics api used by Firefox, Gtk and other desktop projects.

I'll run through the steps involved in porting then try and reach some conclusions at the end :).
This is easiest in …

It can be useful to test sounds in your current engine (esp for testing MOD support), so I've made a tiny sound player for pygame. The code is just this:
{: .alignnone …import sys, pygame
from pygame.locals import *
import pygame.mixer

The current font system is based on tiles, so it should be easy to implement animation and cool stuff …
I've just finished the initial version of the font that'll go into my game ball breaker ("Ball Breaker Caps")... Some of the characters need more work, but it has the retro-future look I'm going for.
This means that I can feel happy about putting in the high score table and …
