I am new to Processing, I have a goal in mind and I have found some tutorials on youtube that I think I can use to reach my goal.  
Here’s the code I’d like to tweak:

```auto
int amount = 300;
int[] x = new int[amount];
int[] y = new int[amount];
int[] z = new int[amount];

void setup() {
  size(500,400,P3D);
  background(0);
  noFill();
  stroke(255);
  strokeWeight(2);
  for(int i = 0; i<amount; i++) {
    x[i] = int(random(-150, 150));
    y[i] = int(random(-150, 150));
    z[i] = int(random(-150, 150));
  }
}
void draw() {
  background(0);
  
  translate(width/2, height/2);
  
  rotateY(frameCount / 100.0);
  
  box(300);
  for(int i=0; i<amount; i++) {
    point(x[i], y[i], z[i]);
  }
}

```

However this yields

```auto

```

I am using Processing 3 under Arch Linux.

May work for some, but have had experience since with another machine with more recent hardware and OS that didn’t.
