Many rotating objects and resetMatrix()

• • Watch Fun Programming [video 30]

  • Here’s Mr Fun’s code:

float r;

void setup()

{

size(400,400);

background(255);

noStroke();

fill(0);

rectMode(CENTER);

r = 0;

}

void draw()

{

background(255);

translate(100,100);

rotate(r);

rect(0,0,80,80);

resetMatrix();

translate(300,100);

rotate(r);

rect(0,0,80,80);

resetMatrix();

translate(100,300);

rotate(r);

rect(0,0,80,80);

resetMatrix();

translate(300,300);

rotate(r);

rect(0,0,80,80);

r = r + 0.05;

}

• • Change the program so each rectangle is a different color

  • Change the program so there are 9 rotating rectangles

• Change the program so that some of the rectangles rotate counter-clockwise.
