Question

I'm trying to test run a simple function that's declared in the first frame. When I write fl_DoRestart(); on frame 50 I get the following error: Uncaught ReferenceError: fl_DoRestart is not defined, but it's defined on frame one. Why's this not working? This used to be very simple in actionscript :(

I eventually need to be able to call this function from another function, right now I'm just testing it.

Here's my function on frame one:

function fl_DoRestart(){
        this.gotoAndPlay(1);
        console.log("play From Start");
    }

该功能已在该框架上定义，但它没有任何参考。您只能从该框架脚本调用它（而this可能是window而不是该脚本）

使用Animate导出时，建议在this上存储方法调用，以便可以访问它们。

this.fl_DoRestart(){
    this.gotoAndPlay(1);
    console.log("play From Start");
}
this.fl_DoRestart();

// From the root
exportRoot.someMoveClip.fl_DoRestart();

// Using a callback
btn.addEventListener("click", someMovieClip.fl_DoRestart.bind(this));

// Shortcut with "on()"
btn.on("click", someMovieClip.fl_DoRestart, this);

希望能够说明这是如何运作的。还需要考虑的另一件事是Animate CC导出中的帧脚本将在每次访问该帧时运行，因此您可能需要在运行脚本之前检查是否已定义事物。

if (this.fl_DoRestart == null) {
   // Then define stuff here
}

干杯。
