==A rectangle in a Sprite is nested within another Sprite. Both Sprite instances are rotated 45 degrees.==



<source lang="java">

package {
import flash.display.GradientType;
import flash.display.Sprite;
import flash.geom.Matrix;
import flash.geom.ColorTransform;
public class Main extends Sprite {

public function Main() {

var rect1:Sprite = new Sprite( );
rect1.graphics.lineStyle(1);

// Create the container
var group:Sprite = new Sprite( );

// Add the rectangles to the container

// Add the container to the main application

==Draw a rectangle==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

try {
drawRectangle(this, 100, 200);
drawRectangle(this, 300, 400);

==Draw Colored Rectangle==



<source lang="java">

package {
import flash.display.Sprite;
import flash.display.Shape;
import flash.display.Graphics;

public class Rectangles extends Sprite {

public function Rectangles() {

==Fill a rectangle==



<source lang="java">

package{

==rotateChildren( ), applies the generalized code from Example 20-4. It randomly rotates all the descendants of a specified container (not just the children).==

rects[i].graphics.beginFill(Math.floor(Math.random( )*0xFFFFFF), 1);
rects[i].graphics.drawRect(0, 0, 100, 50);
rects[i].x = Math.floor(Math.random( )*500);
rects[i].y = Math.floor(Math.random( )*400);
addChild(rects[i]);

stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownListener);
}

==Rotating Rectangles==
