Hi,
I'm starting using Processing these days.

I'd like to create animation with some rectangles on the screen continuosly rotating in some sort of random way.

I created a Rectangle class with a display function,

1. class Rectangle
2. {
3.   float x, y;
4.   float w, h;
5.  
6.   Rectangle(float tempX, float tempY, float tempW, float tempH)
7.   {
8.     x = tempX;
9.     y = tempY;
10.     w = tempW;
11.     h = tempH;
12.   }
13.  
14.   void display()
15.   {
16.     pushMatrix();
17.     translate(x, y);
18.     rotate(radians(random(0, 360)));
19.     rect(x, y, w, h);
20.     popMatrix();
21.   }

but I'm actually drawing the rectangles again and again and not actually moving.

Then, in the draw() function:

1.  void draw()
2. {
3.   for (int i = 0; i < rectNum; i++)
4.   {
5.     a[i].display();
6.   }
7. }

"a" is an array with all the rectangles. I'm not sure if this is the right way to do it. I mean, I'd like all the rectangles rotating at the same time in different ways.

Any suggestion?
