ios - AS3 - 使用循环动态更改 Sprite 属性不起作用

Question

我正在尝试使用循环更改各种 Sprite 的属性。但是我收到此错误消息，但我不知道如何修复它: ReferenceError:错误#1069:在字符串上找不到属性转换，并且没有默认值。 在 LevelScreen/LevelUnlockedColor()[/Users/jakub/Cloud Drive/Documents/JH_WORK/IMPOSSIBLE_SCREEN/LevelScreen.as:232] 在 LevelScreen()[/Users/jakub/Cloud Drive/Documents/JH_WORK/IMPOSSIBLE_SCREEN/LevelScreen.as:31] 在 Function/MainMenu/LoadMenu/taphandler2Click()[/Users/jakub/Cloud Drive/Documents/JH_WORK/IMPOSSIBLE_SCREEN/MainMenu.as:94]

代码如下:

public function LevelUnlockedColor()
    {
        mySharedObject.data.Unlocked = 3;
        mySharedObject.flush();
        var boxes:Array = [];
        for (var i:int = 0; i<mySharedObject.data.Unlocked; i++)
        {
            var spriteName:Sprite = new Sprite();
            spriteName.name = "LVL" + i;// "sprite_0" "sprite_1" ...

            boxes[i] = spriteName.name;
            boxes.push(spriteName);

            var trans:ColorTransform = boxes[i].transform.colorTransform;
            trans.color = uint(0xd982ab);
            boxes[i].transform.colorTransform = trans;

            trace(boxes[i]); //output LVL0, LVL1, LVL2
        }

    }

谢谢。

Answer 1

像这样更改您的 for 循环:

for (var i:int = 0; i<mySharedObject.data.Unlocked; i++)
        {
            var spriteName:Sprite = new Sprite();
            spriteName.name = "LVL" + i;// LVL0 , LVL1 ...

            boxes[i] = spriteName;
            //boxes.push(spriteName);

            var trans:ColorTransform = boxes[i].transform.colorTransform;
            trans.color = uint(0xd982ab);
            boxes[i].transform.colorTransform = trans;

            trace(boxes[i].name); //output LVL0, LVL1, LVL2
        }

通过这种方式，您实际上可以对 Sprite 进行转换，而不是对它们的名称进行转换。如果您还需要在舞台上添加这些对象，请将此行放在 trace 之前:

addChild(boxes[i]);

问题编辑后更新。 好的，尝试更改 LevelUnlockedColor 函数中的 for 循环，如下所示:

 for (var i:int = 1; i<mySharedObject.data.Unlocked; i++)
        {
            var lvl:Sprite = this["LVL" + i];

            var trans:ColorTransform = lvl.transform.colorTransform;
            trans.color = uint(0xd982ab);
            lvl.transform.colorTransform = trans;

        }
