Question

我是flash actionscript3的初学者，我正在寻找动作脚本的时间可以让我在角落中旋转movieclip，就像任何图像经典旋转一样，边界框出现，没有值，只有手动旋转，我能得到任何帮助吗？

如果我理解你想要的东西，我会为你写一些代码。将此代码放在第1帧上。对于要旋转的任何图片，请为其指定实例名称并致电makeRotatable(instanceNameOfYourPictureHere)。

它并不完美，但它可以让你开始。

import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.display.DisplayObject;
import flash.geom.Rectangle;

//change "myPicture" to any object you want to make rotatable
makeRotatable(myPicture);

var currentObject:Object; //holds a reference to whichever objectis currently being rotated
var oldx:Number;//used to determine mouse movement on every new frame
var oldy:Number;
var boundsRect:Rectangle;//used for creating bounding box

function makeRotatable(target:DisplayObject){//this function sets up the rotation center and adds mouse handling

    //creating a container for your picture
    var pictureContainer:MovieClip = new MovieClip; 

    //adding it to the stage
    stage.addChild(pictureContainer); 

    //setting its top left corner, around wich it will rotate, in the center of your picture
    pictureContainer.x = target.x + target.width * 0.5;
    pictureContainer.y = target.y + target.height * 0.5;

    //adding your picture into the container, and moving its center onto the rotational point of the container
    pictureContainer.addChild(target);
    target.x = 0 - target.width * 0.5
    target.y = 0 - target.height * 0.5

    //adding mouse listeners to the container and stage
    pictureContainer.addEventListener(MouseEvent.MOUSE_DOWN, startRotate)
    stage.addEventListener(MouseEvent.MOUSE_UP, stopRotate)


}
function startRotate(e:MouseEvent):void{//sets up for EnterFrame listener and bounding box
    stage.addEventListener(Event.ENTER_FRAME, changeRotation)
    oldx = stage.mouseX
    oldy = stage.mouseY
    currentObject = e.currentTarget
    boundsRect = currentObject.getBounds(currentObject)
    currentObject.graphics.lineStyle(4,0xFF0000);       
    currentObject.graphics.drawRect(boundsRect.x, boundsRect.y, boundsRect.width, boundsRect.height);
}
function stopRotate(e:MouseEvent):void{//removes EnterFrame listener and bounding box
    stage.removeEventListener(Event.ENTER_FRAME, changeRotation)
    currentObject.graphics.clear();
}
function changeRotation(e:Event){//rotates the object based on mouse position and movement respective to objects center point
    if(stage.mouseX>currentObject.x){
        currentObject.rotation += stage.mouseY - oldy
    }else{
        currentObject.rotation -= stage.mouseY - oldy
    }
    if(stage.mouseY<currentObject.y){
        currentObject.rotation += stage.mouseX - oldx
    }else{
        currentObject.rotation -= stage.mouseX - oldx
    }
    oldx = stage.mouseX
    oldy = stage.mouseY
}

使用边界框Flash AC3控制旋转
