FD纯AS项目知识汇总

?设定文件尺寸

[SWF(width = 600,height = 300)]

直接嵌入图片

标签图片应该放在变量声明中
代码放在变量声明，就是类声明后，构造函数前

		[Embed(source = "../ori.png")]
		private var Pori:Class;

注意

1 [Embed(source = "../ori.png")]后面没有分号，不要加分号
2 图片路径，相对于AS文件所在的目录而言，而不是项目路径。
用的时候

		private function init(e:Event = null):void 
		{
			removeEventListener(Event.ADDED_TO_STAGE,init);
			// entry point
			
			var img:Bitmap = new Pori();
			this.addChild(img);
			
		}

Flash项目调库图片：

   var bmd:BitmapData = new img(60,60);
   var bm:Bitmap = new Bitmap(bmd);
???addChild(bm);

?设置官方组件字体大小

			var txt:TextFormat = new TextFormat();
			txt.size = 18;
			StyleManager.setStyle("textFormat",txt);

?颜色变灰滤镜

import flash.filters.ColorMatrixFilter;
//var mat:Array =[0.3086,0.6094,0.082,0.3086,1,0];
var colorMat:ColorMatrixFilter = new ColorMatrixFilter(mat);
this.filters = [colorMat];

按圆排列

			//按圆排列 			
			var max:int = 12;//总数
			var angle:Number = 0;
			var centerX:Number = 300;
			var centerY:Number = 300;
			var radius:Number = 300;//半径
			var speed:Number = uMath.degreesToRadians(360 / max);//弧度

			for (var i:int = 0; i < max; i++) 
			{
				var par:APar = new APar();
				addChild(par);
				par.x = centerX + Math.cos(angle) * radius;
				par.y = centerY + Math.sin(angle) * radius;
				par.rotation = uMath.radiansToDegrees(Math.cos(angle)); 
				angle += speed;
			}

单例写法:

(复杂)

		static public function get instance():SiteEvt {
			if (_instance == null) { 
				_instance = new SiteEvt(_guard = arguments.callee);
			}
			return _instance; 
		}

(简单)

		static public function get instance():SiteEvt {
			return _instance ||= new SiteEvt(_guard = arguments.callee); 
		}
