[AS3]as3下生成随机数(猜硬币)NumberUtilities.random随机数

package { 
    import ascb.util.NumberUtilities; 
     
    import flash.display.Sprite; 
    import flash.events.MouseEvent; 
    import flash.text.TextField; 
     
    public class Sample1118 extends Sprite 
    {    
        private var label:TextField; 
        public function Sample1118() 
        { 
            label = new TextField(); 
            label.background = true; 
            label.backgroundColor = 0xFF0000; 
            label.textColor = 0xF7FCFF; 
            label.autoSize = "left"; 
            this.addChild(label); 
            var sprite:Sprite = new Sprite(); 
            sprite.graphics.beginFill(0xFFFF00); 
            sprite.graphics.drawCircle(100,100,50); 
            sprite.graphics.endFill(); 
            sprite.addEventListener(MouseEvent.CLICK,OnClick); 
            this.addChild(sprite); 
        } 
        private function OnClick(event:MouseEvent):void 
        { 
            if(NumberUtilities.random(0,1)==0) 
            { 
                label.text = "cuplayer.com提示：正面"; 
            } 
            else 
            { 
                label.text = "cuplayer.com提示：背面"; 
            } 
        } 
    } 
} 

用NumberUtilities.random(0,1)方法产生随机数
