For some reason, every time I try to run this program, I just get a gray window. Anybody know how to make this program work? I'm using a combination of Conway's Game of Life (
http://processing.org/learning/topics/conway.html) and the Ess library (
http://www.tree-axis.com/Ess/). Thanks!
Copy code
- import krister.Ess.*;
- int sx, sy;
- float density = 0.5;
- int[][][] world; //triple array
- AudioChannel myChannel1;
- SineWave myWave1;
- int frameDuration;
- void setup()
- {
- size(640, 500, P2D);
- frameRate(12); //set a framerate variable--1000/framerate = new variable called frameDuration
- sx = width;
- sy = height;
- world = new int[sx][sy][2];
- frameDuration = 1000/12;
- // Set random cells to 'on'
- for (int i = 0; i < sx * sy * density; i++) {
- world[(int)random(sx)][(int)random(sy)][1] = 1;
- }
- // start up Ess
- Ess.start(this);
- // create a new AudioChannel
- myChannel1=new AudioChannel();
- // set the channel size to 5 seconds
- myChannel1.initChannel(myChannel1.frames(frameDuration));
- }
- void draw()
- {
- background(0);
- // Drawing and update cycle

- myWave1.generate(myChannel1,0,myChannel1.frames(frameDuration));
