动作脚本2上的平移和缩放阶段

Question

我试图在动作脚本2上创建缩放和平移选项。我想在舞台上做，而不是在电影剪辑上。我已经做了一个基本的编码，但我想创建拖动和缩放选项。任何帮助都将不胜感激。

这是我的代码。我在舞台上有两个影片剪辑放大和缩小舞台

zoom_mc.onPress = function() {
    var zinxpos:Number;
    var zinypos:Number;
    zinxpos=zoom_mc._x;
    zinypos=zoom_mc._y;
    zoom_mc.onEnterFrame = function() {
    Mouse.hide();
    this._x = _root._xmouse;
    this._y = _root._ymouse;
    }   
    _root.onMouseDown = function() {
    this._xscale+=10;
    this._yscale+=10;
}
}

zoomout_mc.onPress = function() {   
    zoom_mc._x=zinxpos;
    zoom_mc._y=zinypos;
    zoomout_mc.onEnterFrame = function() {
    Mouse.hide();
    this._x = _root._xmouse;
    this._y = _root._ymouse;
    }   
    _root.onMouseDown = function() {
    this._xscale-=10;
    this._yscale-=10;
}
}

Answer 1

这应该可以完成这项工作。

var $stage = this;
var isDragging = false;
var mouseDownX = 0;
var mouseDownY = 0;

$stage.onEnterFrame = function() {      
    if(isDragging){
        $stage._x += $stage._xmouse - mouseDownX;
        $stage._y += $stage._ymouse - mouseDownY;
    }       
} 

$stage.onMouseDown = function() {   
    isDragging = true;
    mouseDownX = $stage._xmouse;
    mouseDownY = $stage._ymouse;
}

$stage.onMouseUp = function() { 
    isDragging = false;
}

zoom_mc.onPress = function() {
   $stage._xscale += 10;
   $stage._yscale += 10;
}

zoomout_mc.onPress = function() {   
   $stage._xscale -= 10;
   $stage._yscale -= 10;    
}
