Hi, you can probably tell by the name of this subject how new I am to Processing... I am learning about it in school, and I've been working on this code for a project...

I was just wondering how I could manage to make the individual rectangles grow in size upon rollover while they move in a wave like motion... I used the Additive Wave example as a basis, and I'm making changes from there.

Here is the code so far:


int xspacing = 10;  
int w;            
int maxwaves = 15;

float theta = 0.0f;
float[] amplitude = new float[maxwaves];  
float[] dx = new float[maxwaves];        
float[] yvalues;                        

void setup() {
 size(800,600);
 frameRate(60);
 colorMode(RGB, 255, 255, 255, 100);
 smooth();
 w = width+16;

 for (int i = 0; i < maxwaves; i++) {
   amplitude[i] = random(10,30);
   float period = random(100,200);
   dx[i] = (TWO_PI / period) * xspacing;
 }

 yvalues = new float[w/xspacing];
}

void draw() {
 background(255);
 calcWave();
 renderWave();
}

void calcWave() {

 theta += 0.03;


 for (int i = 0; i < yvalues.length; i++) {
   yvalues[i] = 0.0f;
 }

 for (int j = 0; j < maxwaves; j++) {
   float x = theta;
   for (int i = 0; i < yvalues.length; i++) {

     if (j % 2 == 0)  yvalues[i] += sin(x)*amplitude[j];
     else yvalues[i] += cos(x)*amplitude[j];
     x+=dx[j];
   }
 }
}

void renderWave() {
 noStroke();
 fill(120, 30);
 rectMode(CENTER);
 for (int x = 0; x < yvalues.length; x++) {
   rect(x*xspacing,width/2+yvalues[x],30,30);
 }
}

If any of you experts could give me some idea of how to integrate the mouseX or mouseY function into this to make the shapes grow, I'd be utterly grateful!!!

Thanks very much for the help.
