Flash AS3 |平移/缩放鼠标输入 [英] Flash AS3 | Pan / Zoom with mouse input

问题描述

我正在查看是否有人可以帮我弄清楚如何在Flash AS3中的已经播放的视频上创建一个平移效果，在这个视频中，相机是由鼠标指向的。

例如，这里的游戏 http://www.kongregate.com/games/jorjeade/seven-deadly-sins （跳过介绍快速到达）有一个世界地图，通过使用鼠标左右摇摆。我正在尝试为我的Flash视频获得类似的效果。

任何帮助编码这将是真棒！我也想看看是否可以得到一个基本的缩放功能，这个平移，也是用户可以通过键盘或类似的控制。

感谢任何帮助！谢谢。

解决方案

对于我的代码来说，将您的影片剪辑定位点设置为居中。 b
$ b

  myMovieClip.y = stage.stageHeight / 2; 
 addEventListener（MouseEvent.MOUSE_MOVE，panFunction）; 
 private function panFunction（me：MouseEvent）：void {
 myMovieClip.x = stage.stageWidth / 2  - （stage.mouseX  -  stage.stageWidth / 2）; 
} 
  

这将给出一个1比1的动作，用鼠标立即更新。如果你愿意的话，你可以投入一些乘数或者缓解效应，但是希望这会让你朝着正确的方向前进。

I was looking to see if someone can help me figure out how to create a panning effect over an already playing video in Flash AS3, where the camera is directed by where the mouse is.

For example, this game here http://www.kongregate.com/games/jorjeade/seven-deadly-sins (skip the intro to get to it quickly) has an over world map which pans around by using the mouse. I'm trying to achieve a similar effect for my flash video.

Any help coding this would be awesome! I'm also looking to see if I can get a basic zoom function working alongside this panning, also something that the user can control though the keyboard or similar.

I appreciate any help! Thanks.

解决方案

For my code to work as it is, set your movie clip anchor point to "centered."

myMovieClip.y = stage.stageHeight / 2;  
addEventListener(MouseEvent.MOUSE_MOVE, panFunction);
private function panFunction(me:MouseEvent):void {
    myMovieClip.x = stage.stageWidth/2 - (stage.mouseX - stage.stageWidth/2);
}

This will give a 1 to 1 motion that updates immediately with the mouse. You can throw in some multipliers or easing effect if you want, but hopefully this gets you going the right direction.
