AS3 / removeChild之/的addChild通过点击按钮 [英] AS3 / removeChild/addChild by clicking button

问题描述

我有几个电影剪辑成一个帧中的阶段的大小，并予有通过这些网页之间的按钮，切换

I have several movie clips into a frame the size of the stage and I have to switch through a button between those pages.

所以，如果我preSS按钮，应该所有的其他帧removeChild之和的之一，他被称为去的addChild。

So if I press button, should all the other frames removeChild and the one where he is called to go addChild.

编辑：我有动作放置在影片剪辑的时间轴中使按键不会在舞台上，但我把影片剪辑使用动作脚本

I have the actionscript placed in the timeline of the movieClip so the button is not on the stage but I put in the movie clip using action script.

那么，什么DodgerThud这里显示是不可能的，因为按钮，因为这改变了在影片剪辑（的）。

So what DodgerThud showed here is not possible because the button has changed since that is in the movieClip('s).

我想我需要把相同的code在每一个动画片段。

I think I need to place the same code in every movieClip.

推荐答案

把所有的影片剪辑到一个Vector或数组。

Put all of your MovieClips into a Vector or Array.

当你点击按钮，你应该循环通过矢量/阵列，并检查当前的影片剪辑在舞台上与包含项（DisplayObject）。如果影片剪辑是目前在舞台上，将其删除，并添加另一个舞台，例如，下一个在矢量/阵列。

When you click the button, you should cycle through the Vector/Array and check if the MovieClip is currently on stage with contains(DisplayObject). If the Movieclip IS currently on the stage, remove it and add another one to the stage, for example, the next one in the Vector/Array.

var vec:Vector.<MovieClip> = new Vector.<MovieClip>
vec[0] = new MovieClip();
vec[1] = new MovieClip();  //example with MovieClips
vec[2] = new MovieClip();

addChild(vec[0]);  //add one of the MovieClips to stage

button.addEventListener(MouseEvent.CLICK, onClick);

function onClick(e:MouseEvent):void
{
    for(var i:int = 0; i < vec.length; i++) //go through the Vector one by one
    {
         if(contains(vec[i])  //if the Object at position i in the Vector is on stage
         {
              removeChild(vec[i]); //remove the Object
              var next:int = i;    //create a temporary holder
              if(next == vec.length) //check if the displayed Object was the last in the list
              {
                   next = 0;  //if so, set to 0
              }else{
                   next++; //otherwise, only add 1
              }
              addChild(vec[next]); //add the next Object to the stage. If the removed Object was the last in the Vector, it'll add the first Object in the Vector to the list
              break; //escape the for loop, otherwise it'll always only show the last Object
         }

    }
}
