AS3多个侧翻对象 [英] AS3 Multiple Rollover objects

问题描述

例如图片

很新的AS3。很抱歉，如果这个问题是非常基本的，我试图四处寻找正确的答案，但只找到半相关的问题。请帮助！

目标：我要同台的多个侧翻影片剪辑可以独立发挥出自己的动画

到目前为止，我只有1 MovieClip对象，其行为正常。如果我添加另一个，第一个表现正常，但第二次没有出现在所有。据我所知，它可能只是打电话，我第一次投进阶段，我需要改变我的code有一个大师或父影片剪辑和实例应该是孩子们的情况，但我不知道如何写，在code。最终，这个想法是，我想补充我的孩子影片剪辑，然后略微改变在每个片段的内容。

我的code到目前为止：

 进口flash.events.MouseEvent;


clip_boxes.removeEventListener（MouseEvent.ROLL_OUT，clipOut）;
clip_boxes.addEventListener（MouseEvent.ROLL_OVER，clipOver）;


功能clipOver（事件：MouseEvent）方法：无效{

 clip_boxes.addEventListener（MouseEvent.ROLL_OUT，clipOut）;
 clip_boxes.removeEventListener（MouseEvent.ROLL_OVER，clipOver）;
 clip_boxes.gotoAndPlay（OVER）;

};

功能clipOut（事件：MouseEvent）方法：无效{

clip_boxes.addEventListener（MouseEvent.ROLL_OVER，clipOver）;
clip_boxes.removeEventListener（MouseEvent.ROLL_OUT，clipOut）;
clip_boxes.gotoAndPlay（出）;

};
 

解决方案

有几个方法可以做到这一点。我会以最坏的最好列出。

1. 手动添加侦听每个实例。

   当你将一个新的影片剪辑到时间线，你需要给它一个实例名称（在属性面板中找到）。我不知道，如果 clip_boxes 的是，你打算把所有的电影剪辑上，或父母的时间表，如果它是你的影片剪辑本身之一。

   假设你有3剪辑实例名称： MC1 ， MC2 ， MC3 ，你可以这样做

   （包含它们的时间轴的第一帧）

     MC1.addEventListener（MouseEvent.ROLL_OVER，clipOver）;
   MC2.addEventListener（MouseEvent.ROLL_OVER，clipOver）;
   MC3.addEventListener（MouseEvent.ROLL_OVER，clipOver）;
   
   //如果你有一大堆，你也可以使用一个循环来添加所有监听器
   
   
   //你用event.currentTarget获得referce对象的侦听器附加到 - 这种方式，你只需要这一个处理函数
   功能clipOver（事件：MouseEvent）方法：无效{
       影片剪辑（event.currentTarget）.addEventListener（MouseEvent.ROLL_OUT，clipOut）;
       影片剪辑（event.currentTarget）.gotoAndPlay（在）;
   };
   
   功能clipOut（事件：MouseEvent）方法：无效{
       影片剪辑（event.currentTarget）.removeEventListener（MouseEvent.ROLL_OUT，clipOut）;
       影片剪辑（event.currentTarget）.gotoAndPlay（外出）;
   };
    

2. 使用继承

   这将涉及建立一个基础类文件（。至于文件），然后可以连接到您的所有影片剪辑，使他们继承了所有内code。这里是一个类文件，它会为你做这个的例子：（让我们假设这是一个名为您的根目录SubClass.as文件）

    包{
       进口的flash.display.MovieClip;
   进口flash.events.MouseEvent;
   
       公共类子类来扩展MovieClip的{
           公共职能SubClass中（）{
               this.addEventListener（MouseEvent.ROLL_OVER，侧翻，假，0，真正的）;
           }
   
           公共职能翻转（事件：MouseEvent）方法：无效{
               this.addEventListener（MouseEvent.ROLL_OUT，部署，假，0，真正的）;
               this.gotoAndPlay（OVER）;
           }
   
           公共职能部署（事件：MouseEvent）方法：无效{
               this.removeEventListener（MouseEvent.ROLL_OUT，部署，假）;
               this.gotoAndPlay（出）;
           }
       }
   }
    

   现在，当您创建的影片剪辑（或右键单击库中，选择属性），你可以设置一个基类他们。如果您设置的基类的类上面，它们会自动使用code以上，并具有鼠标输入/输出连接。 （只要他们有输出/过帧标签将只是工作）。

Very new to AS3. Sorry if this question is really basic, I tried looking around for the right answer but only found semi-related questions. Please help!!

Objective: I want multiple rollover MovieClips on the same stage that play out their animations independently.

So far, I have only 1 MovieClip object that behaves properly. If I add another, the first one behaves properly but the second doesn't appear at all. I understand that it's probably only calling the instance that I first dropped into the stage and that I need to change my code to have a "master" or parent MovieClip and that the instances should be the children, but I'm not sure how to write that in code. Eventually, the idea is that I add my children movieclips, and then slightly change the content in each clip.

My code so far:

import flash.events.MouseEvent;


clip_boxes.removeEventListener(MouseEvent.ROLL_OUT, clipOut);
clip_boxes.addEventListener(MouseEvent.ROLL_OVER, clipOver);


function clipOver(event:MouseEvent):void {

 clip_boxes.addEventListener(MouseEvent.ROLL_OUT, clipOut);
 clip_boxes.removeEventListener(MouseEvent.ROLL_OVER,clipOver);
 clip_boxes.gotoAndPlay("Over");

};

function clipOut(event:MouseEvent):void {

clip_boxes.addEventListener(MouseEvent.ROLL_OVER, clipOver);   
clip_boxes.removeEventListener(MouseEvent.ROLL_OUT, clipOut);
clip_boxes.gotoAndPlay("Out");

};

解决方案

There are a few ways you can do this. I'll list in order of worst to best.

1. Manually add listeners to each instance.

   When you drag a new MovieClip onto the timeline, you need to give it an instance name (found in the properties panel). I'm not sure if clip_boxes is a parent timeline that you intend to have all your movie clips on, or if it is one of your movie clips itself.

   Assuming you have 3 clips with the instance names: MC1,MC2,MC3, you could do this (on the first frame of the timeline that contains them)

   MC1.addEventListener(MouseEvent.ROLL_OVER, clipOver);
   MC2.addEventListener(MouseEvent.ROLL_OVER, clipOver);
   MC3.addEventListener(MouseEvent.ROLL_OVER, clipOver);
   
   //If you had a whole bunch, you could also use a loop to add all the listeners
   
   
   //you use event.currentTarget to get a referce to the object the listener was attached to - this way you only need this one handler function
   function clipOver(event:MouseEvent):void {
       MovieClip(event.currentTarget).addEventListener(MouseEvent.ROLL_OUT, clipOut);
       MovieClip(event.currentTarget).gotoAndPlay("Over");
   };
   
   function clipOut(event:MouseEvent):void {  
       MovieClip(event.currentTarget).removeEventListener(MouseEvent.ROLL_OUT, clipOut);
       MovieClip(event.currentTarget).gotoAndPlay("Out");
   };
   

2. Use Inheritance

   This would involve creating a base class file (.as file) that you can then attach to all your MovieClips so they inherit all the code within. Here is an example of a class file that would do this for you: (lets assume this is a file called SubClass.as in your root directory)

   package {
       import flash.display.MovieClip;
   import flash.events.MouseEvent;
   
       public class SubClass extends MovieClip {
           public function SubClass(){
               this.addEventListener(MouseEvent.ROLL_OVER, rollOver,false,0,true);
           }
   
           public function rollOver(event:MouseEvent):void {
               this.addEventListener(MouseEvent.ROLL_OUT,rollOut,false,0,true);
               this.gotoAndPlay("Over");
           }
   
           public function rollOut(event:MouseEvent):void {
               this.removeEventListener(MouseEvent.ROLL_OUT,rollOut,false);
               this.gotoAndPlay("Out");
           }
       }
   }
   

   Now, when you create your movieClips (or right click in the library and select properties), you can set a baseClass for them. If you set the base class to the class above, they automatically use the code above and have the mouse over/out attached. (as long as they have the Out/Over frame labels it will just work).
