無法使用符號時間軸中的值更改主時間軸上的變量

Question

我是編碼新手，因此很難找到答案。

基本上，我正在嘗試使用ActionScript 3在Flash CS5.5中制作換裝游戲。當前問題是，我正在嘗試通過不同的衣服使顏色保持不變（例如：如果您有藍色的T-襯衫，然后換上衣服，衣服應該是藍色的。如果您將衣服上的顏色更改為紅色，然后又換回T恤，那么T恤現在應該是紅色的。）

我正在使用我在Photoshop中創建的資產，並將所有資產都放在Movie Clip符號中（因此，所有T恤都在Symbol T恤中，所有連衣裙都在Symbol Dress中，依此類推）； 而且最重要的是，我將所有相同顏色的衣服放在它們各自符號的相同關鍵幀編號中（所有紅色衣服在關鍵幀1中，所有藍色衣服在關鍵幀2中，依此類推）。

我想做的是每當玩家單擊顏色按鈕時，在Symbol時間軸中為變量分配一個數字，然后在Main Timeline中讀取該變量，將該變量存儲在Main Timeline中的另一個變量中，以便其持久存在即使符號發生變化，然后讓另一個符號讀取主時間軸上的變量，以應用於告訴其去向的函數。

我當前的問題是我無法終生讓主時間軸上的變量讀取Symbol上的變量，因此無法更新。

這是代碼：

//MAIN SCENE SCRIPT

//STOP EVERYTHING FROM STARTING
stop();

//-----------------------------------------------------------------------
//-----------------------------------------------------------------------

//DECLARE COLOR VARIABLE IN MAIN TIMELINE AND ASSIGN VALUE FROM SQUARE 
SYMBOL
var color = square.KeyColor;
//MOVE COLOR VARIABLE TO PERMANENT VARIABLE
var KeepColor:int = color;

// change color variable IF THE VALUE IS NOT 1
function ChangeColor () : void
{
  if(KeepColor != 1)
    {
      if (square.KeyColor != 1)
      {
        KeepColor = square.KeyColor;
        trace("color set to square value" )
      }

      else if (pentagon.KeyColor != 1)
      {
        KeepColor = pentagon.KeyColor;
        trace("color set to pentagon value")
      }

      else
      {
        trace ("there is an error")
        //break;
      }

    }
}

    //GO TO FIRST KEYFRAME IN MAIN TIMELINE AND STOP
    gotoAndStop(1)
    //ASSIGN KEYCOLOR VALUE
    square.KeyColor = color;
    //PRINT COLOR CODE
    trace("color is  " + color);

}

    KeyColor = 1;
    //PRINT COLOR CODE OF FIRST COLOR

    //change root color number
    MovieClip(root).color = KeyColor;

}

//-----------------------------------------------------------------------

謝謝您的幫助！

通過使用影片剪輯的.currentFrame屬性，可以保存每種布料的幀號，在更改顏色時始終更新它，並在更換布料時使用它。

//Reference to the current shirt or dress:
var shirt:MovieClip = basicShirt; //update this when you change shirt to dress etc

//Variables for colors (frames)
var shirtColor:int = 1;

//Changing shirt color:
shirtColorButton.addEventListener(MouseEvent.CLICK, changeShirtColor);

function changeShirtColor(evt:MouseEvent):void{
    //Other handy property for you might be .totalFrames:
    if(shirt.currentFrame < shirt.totalFrames){
        shirtColor++;
    }else{
        shirtColor = 1;
    }
    shirt.gotoAndStop(shirtColor);
}

因此，現在，如果您將襯衫換成正裝，您可以簡單地從舞台上移走襯衫，在舞台上增加連衣裙，然后：

//function that creates the shirt:
shirt = basicDress;
shirt.gotoAndStop(shirtColor);

而且，如果您確實需要顏色名稱，則可以使用框架標簽，也可以將顏色名稱存儲到數組中，因為順序總是相同的，例如：

var colorNames:Array = ["Blue","Red","Green"];
...
trace("Shirt color is "+colorNames[shirtColor - 1]);
