Question

我正在制作互动游戏 - 到目前为止我已经有了这个代码。其中drop1是一枚硬币而用户将其放入target1（盒子）中，一旦完成，他们就可以在下一个场景中观看视频播放。如你所知，当drop1（硬币）掉落到盒子上时，硬币就会消失

  //Array to hold the target instances, the drop instances,   
  //and the start positions of the drop instances.
  var hitArray:Array = new Array(hitTarget1);
  var dropArray:Array = new Array(drop1);
  var positionsArray:Array = new Array();


  //This adds the mouse down and up listener to the drop instances
  //and add the starting x and y positions of the drop instances
  //into the array.
  for (var i:int = 0; i < dropArray.length; i++) {
  dropArray[i].buttonMode = true;
  dropArray[i].addEventListener(MouseEvent.MOUSE_DOWN, mdown);
  dropArray[i].addEventListener(MouseEvent.MOUSE_UP, mUp);

  positionsArray.push({xPos:dropArray[i].x, yPos:dropArray[i].y});
  }

  //This drags the object that has been selected and moves it
  //to the top of the display list. This means you can't drag
  //this object underneath anything.
  function mdown(e:MouseEvent):void {
  e.currentTarget.startDrag();
  setChildIndex(MovieClip(e.currentTarget), numChildren - 1);
  }

  //This stops the dragging of the selected object when the mouse is
  //released. If the object is dropped on the corresponding target
  //then it get set to the x and y position of the target. Otherwise
  //it returns to the original position.
  function mUp(e:MouseEvent):void {
  var dropIndex:int = dropArray.indexOf(e.currentTarget);
  var target:MovieClip = e.currentTarget as MovieClip;

  target.stopDrag();

  if (target.hitTestObject(hitArray[dropIndex])) {
  target.x = hitArray[dropIndex].x;
  target.y = hitArray[dropIndex].y;
  drop1.visible = false;
  }else{
  target.x = positionsArray[dropIndex].xPos;
  target.y = positionsArray[dropIndex].yPos;

  }
  }

现在......我希望代码知道用户何时将硬币放入盒子中，如果用户有，他们就可以观看视频，但只有当他们将硬币放入盒子中时才能观看视频。我怎么能这样编码？

请帮忙。

谢谢

如果您还在苦苦挣扎，可以随时尝试阅读手册。我怀疑这就是你到目前为止没有答案的原因。在帧/场景之间旅行需要gotoAndPlay或gotoAndStop。检查：http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/MovieClip.html#gotoAndPlay()

查看场景跳转代码的示例二。在哪里说＆＃34;介绍＆＃34; （框架标签）可以只使用一个数字，但场景必须有名称......例如：

mc1.gotoAndPlay("intro", "Scene 12");

或者在你的情况下如下（假设你已将其命名为scene_video）

if (target.hitTestObject(hitArray[dropIndex])) {
target.x = hitArray[dropIndex].x;
target.y = hitArray[dropIndex].y;
drop1.visible = false;
gotoAndStop(1, "scene_video");     }

我再次假设您的视频播放器位于该场景的第1帧，因此停在那里可让用户有机会观看视频播放器。

AS3 - 使用If语句拖动到Next Scene。
