经过长时间的闪光挣扎......
我有一些动画片段，我想只对我MOUSE_OVER的动画片段进行过滤。
对于每个动画片段，必须采用与MOUSE_OVER和MOUSE_OUT类型不同的方式。
After a long time of struggling with flash...
I have some movieclips and I would like to get a filter only to that movieclip that I MOUSE_OVER.
There must be a different way than type MOUSE_OVER and MOUSE_OUT for every single movieclip.

你可以通过几种方式解决这个问题。
最好：
使用继承。
如果您创建的类文件具有一组项的所有常用功能，则可以让MovieClip继承该功能。 因此，您将在根目录中创建一个如下所示的文件。 （我们称之为FilteredMC.as ）
package { import flash.events.MouseEvent; public class FilteredMC extends MovieClip { //the function that matches the name of class, is what runs when the object is created public function FilteredMC():void { this.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); this.addEventListener(MouseEvent.MOUSE_OUT,mouseOut); } private function mouseOver(e:MouseEvent):void { this.filters = [...your filter...] } private function mouseOut(e:MouseEvent):void { this.filters = []; } } }然后在FlashPro中，右键单击应具有此功能的库对象，转到“ 属性 ”，然后选择“export for actionscript”，然后在“ 基类 ”文本字段中输入： FilteredMC 。 把你想要的任何东西作为类名（只要它是唯一的，不与任何其他类或关键字冲突）
好：
如果所有项目都是容器的唯一子项，则可以循环遍历该容器的所有子项并添加代码:(您也可以使用一组项目执行此操作）
var i:int = containerMC.numChildren; while(i--){ if(containerMC.getChildAt(i) is MovieClip){ setupFilter(containerMC.getChildAt(i) as MovieClip); } } function setupFilter(mc:MovieClip):void { mc.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); mc.addEventListener(MouseEvent.MOUSE_OUT,mouseOut); } function mouseOver(e:MouseEvent):void { //the event's 'currentTarget' property is the item you added the listener to MovieClip(e.currentTarget).filters = [...your filter...] } function mouseOut(e:MouseEvent):void { MovieClip(e.currentTarget).filters = []; }There are a few ways you could go about this.
Best:
use inheritance.
If you create a class file that has all the common functionality of a group of items, you can have your MovieClips inherit that functionality. So you'd create a file in your root directory that looks like this. (let's call it FilteredMC.as)
package { import flash.events.MouseEvent; public class FilteredMC extends MovieClip { //the function that matches the name of class, is what runs when the object is created public function FilteredMC():void { this.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); this.addEventListener(MouseEvent.MOUSE_OUT,mouseOut); } private function mouseOver(e:MouseEvent):void { this.filters = [...your filter...] } private function mouseOut(e:MouseEvent):void { this.filters = []; } } }Then in FlashPro, right click your library objects that should have this functionality, go to "properties", and choose "export for actionscript" then in the "base class" text field, put: FilteredMC. Put whatever you'd like as the class name (so long as it's unique and doesn't clash with any other class or keyword)
Good:
If all your items are the sole children of a container, you can loop through all the children of that container and add the code: (you could also do this with an array of items)
var i:int = containerMC.numChildren; while(i--){ if(containerMC.getChildAt(i) is MovieClip){ setupFilter(containerMC.getChildAt(i) as MovieClip); } } function setupFilter(mc:MovieClip):void { mc.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); mc.addEventListener(MouseEvent.MOUSE_OUT,mouseOut); } function mouseOver(e:MouseEvent):void { //the event's 'currentTarget' property is the item you added the listener to MovieClip(e.currentTarget).filters = [...your filter...] } function mouseOut(e:MouseEvent):void { MovieClip(e.currentTarget).filters = []; }更多推荐
