如何回调到另一个堆栈？ - 动态代码

Question

我创建循环视频。

我想将函数回调用于另一个堆栈。

这是我的代码：

   start using stack "Widget Project"
   put the duration of player "Player" into tDuration
   put tDuration & ",restartPlayer" into tCall
   set the callbacks of player "Player" to tCall

如果要在电影结束播放时执行脚本，则不需要使用回调。您可以使用playStopped消息：

on beforeYouStartPlayingTheMovie
   start using stack "Widget Project"
end beforeYouStartPlayingTheMovie

-- in stack "Widget Project"
on playStopped
  if the id of the target is the id of player "Player" of stack "Your Stack" then
    -- do whatever you want here
  end if
  pass playStopped
end playStopped

在iOS和Android上使用playerFinished消息。
