Code Question (bouncing objects)

wfox

What kind of code should I use to make an object bounce around the "box" ?

Processing code?

float px,py,pz,vx,vy,vz;
void setup(){
  size(220,220,P3D);
  vx=random(-1,1);
  vy=random(-1,1);
  vz=random(-1,1);
}

void draw(){
  background(0);
  translate(110,110,-20);
  rotateX(map(mouseY,0,height,-PI,PI));
  rotateY(map(mouseX,0,width,-PI,PI));
  noFill();
  stroke(255);
  box(100);
  px+=vx;py+=vy;pz+=vz;
  if(abs(px)>45)vx*=-1;
  if(abs(py)>45)vy*=-1;
  if(abs(pz)>45)vz*=-1;
  translate(px,py,px);
  fill(255,0,0);
  noStroke();
  box(10);
}

I just don't know why it isn't bouncing in random directions?

How cool the example! I've got 1 online, but it doesn't rotate the big cube: :(
