Actionscript 委托函数麻烦... (myFunction).toString() 打印 function Function() {}
我有一个 ViewToActionMap 对象的向量，它具有以下构造函数：(
public function ViewToActionMap(_forModule:eModule,
_forAction:eViewAction,
_toFunction:Function,
_withArgs:Array=null):void{
forModule = _forModule;
forAction = _forAction;
toFunction = _toFunction;
withArgs = _withArgs;
}
eModule / eViewAction / withArgs are与我的帖子无关）
所以我的向量看起来像这样（为了简洁起见，我只包含了它的第一个对象..）：
const actionMappings:Vector.<ViewToActionMap> = new <ViewToActionMap>
[new ViewToActionMap(eModule.WELCOME,
eViewAction.GP_CONTINUE_BUTTON,
startGame, //<--- the source of my troubles!
null)
]
其中 startGame 是一个简单的函数：
function startGame():void{ }
/////// //////// 所以这就是问题 ///////////////
如果我循环遍历 actionMappings[0] 的属性，这里是输出：
gpContinueButton
welcome
function Function() {} //<---------- why isn't this working?
null
为什么 .toFunction 一个空函数，而不是对 startGame() 的引用？？？
谢谢！
I've got a Vector of ViewToActionMap objects, which have following constructor:
public function ViewToActionMap(_forModule:eModule,
_forAction:eViewAction,
_toFunction:Function,
_withArgs:Array=null):void{
forModule = _forModule;
forAction = _forAction;
toFunction = _toFunction;
withArgs = _withArgs;
}
(eModule / eViewAction / withArgs aren't relevant to my post)
So my vector looks like this (for brevity, i've only included its first object..):
const actionMappings:Vector.<ViewToActionMap> = new <ViewToActionMap>
[new ViewToActionMap(eModule.WELCOME,
eViewAction.GP_CONTINUE_BUTTON,
startGame, //<--- the source of my troubles!
null)
]
Where startGame is a simple function:
function startGame():void{ }
/////////////// so here's the problem //////////////
if I loop through the properties of actionMappings[0], here is the output:
gpContinueButton
welcome
function Function() {} //<---------- why isn't this working?
null
Why is the value of .toFunction an empty function, instead of a reference to startGame()????
Thanks!

解决了：
似乎跟踪
".toFunction"的值只会产生这样的结果：function Function() {}一旦我修复了一个不相关的错误，我就能够调用startGame() 成功。
Solved it:
it seems that tracing the value of
".toFunction"simply yields this:function Function() {}Once i fixed an unrelated bug, I was able to call startGame() successfully.
