Movieclip不能自行移动

在我的游戏中，你可能会注意到这个人不会自行移动。您必须单击一次屏幕才能让该人用箭头键左右移动。

这是我使用，使该名男子的举动文件。我在哪里更改代码以使游戏正常工作，以便男士在“Go！”之后移动，而且您不必点击屏幕。

我的另一个问题是：当你按“P”时，你可以暂停游戏。但是，您可能会在通过再次按下“P”键取消暂停游戏后注意到，计时器已关闭了您暂停的秒数。该代码也是定时器的代码。我在代码中更改了哪些内容以使计时器正确运行，这意味着在暂停游戏之后，它不会跳过暂停的秒数，而是从停止的位置继续。

代码不足。它在哪里显示“Go！”？你也没有正确地清除移动的变量，我在向左移动时死亡，并且随后的所有重试使得该人立即向左移动而无法取消移动。 – Vesper

关于使计时器工作排除暂停时间 - 不要使用'getTimer（）'来代替这个，而是测量在同一个var'currentTime'中传递的帧，如果暂停，不要增加var。 – Vesper

它看起来像我“更新”是你移动的人。这是从startGame调用的，它只在buttonClickHandler4和buttonClickHandler6（KeyboardEvent的绑定位置）中调用。所以我不会指望这个人移动，直到其中一个点击处理程序被调用。也许调用startGame并绑定constructer中的关键事件？ – dhc

编辑：我想通了，通过此链接问题：http://www.trainingtutorials101.com/2010/10/keyboard-events-wont-work-unless-user.html

我不得不使用命令stage.focus = this集中在舞台上我的影片剪辑的人，所以这样它可以侦听键盘事件，而我的鼠标点击屏幕。

并删除男人周围的黄色矩形我使用了命令stage.stageFocusRect = false。

感谢@dhc和@Vesper的所有帮助。

你快乐工作了！ – dhc

这是太长的评论线程为这个问题。在你调用buttonClickHandler4之后，你的键盘事件应该正常工作。

设置调试点或跟踪语句，查看是否调用了buttonClickHandler4。添加相同的名称以确保正在调用downKey和move。这应该缩小问题的范围。

好吧我会尝试，谢谢。 –

按钮点击处理程序4正在调用，以及downKey和移动，但问题是，您必须至少点击一次屏幕才能让该移动。 –

这是怎么回事？ –
