是否可以在 Actionscript 2.0 中访问框架的 NAME 属性？

发布于 2024-09-06 20:30:53 字数 215 浏览 8 评论 0原文

我将帧 50 命名为 _foo （在 IDE 中）。

我可以随时跟踪 this._currentFrame （并获取一个数字）。

我可以gotoAndPlay("_foo");。

但是我怎样才能知道电影播放时当前帧是否是 _foo 呢？

这可能吗？

在 ActionScript 2 中，无法访问当前帧的名称/标签（此功能是在 ActionScript 3 中添加的）。

但是，您可以使用以下代码来确定播放期间的当前帧编号：

// This is the frame number we want to look out for.
var targetFrame : Number = 50;

// Crate an onEnterFrame function callback, this will be
// called each time the current MovieClip changes from one
// frame to the Next.
onEnterFrame = onEnterFrameHandler;

/**
 * This function is called each time the MovieClip enter a 
 * new frame during playback.
 */
function onEnterFrameHandler() : Void
{
    trace("_currentframe: " + _currentframe);
    if (_currentframe == targetFrame)
    {
        trace("Playhead is at Frame: " + _currentframe);

        // Stop playback and remove the onEnterFrame callback.
        stop();
        onEnterFrame = null;
    }
}

要进一步阅读，请务必检查 Adobe livedocs 条目中的 MovieClip.onEnterFrame

In ActionScript 2 there is no way to access the Name / Label of the current frame (this feature was added in ActionScript 3).

However, you could use the following code to determine the current frame number at during playback:

// This is the frame number we want to look out for.
var targetFrame : Number = 50;

// Crate an onEnterFrame function callback, this will be
// called each time the current MovieClip changes from one
// frame to the Next.
onEnterFrame = onEnterFrameHandler;

/**
 * This function is called each time the MovieClip enter a 
 * new frame during playback.
 */
function onEnterFrameHandler() : Void
{
    trace("_currentframe: " + _currentframe);
    if (_currentframe == targetFrame)
    {
        trace("Playhead is at Frame: " + _currentframe);

        // Stop playback and remove the onEnterFrame callback.
        stop();
        onEnterFrame = null;
    }
}
