PowerPoint VBA：如何将动画开始事件设置为“与上一个”

Question

在PowerPoint宏中，我希望将动画选项卡上的“定时”组中的“开始”设置为“与上一个”。今天是我第一次使用VBA，所以请不要嘲笑我的代码：

Sub adjustAll（）将osld调暗为幻灯片将oshp调暗为形状

For Each osld In ActivePresentation.Slides
    For Each oshp In osld.Shapes
        If oshp.Type = msoMedia Then
            If oshp.MediaType = ppMediaTypeSound Then
                oshp.Left = 460.7499
                oshp.Top = 250.7499
                oshp.AnimationSettings.PlaySettings.LoopUntilStopped = True
            End If
        End If
    Next oshp
Next osld
End Sub

也许我需要使用AddEffect()，但这似乎有点过于复杂？我看过一些文档和帖子，但没有找到要设置的属性或要应用的值。

For Each osld In ActivePresentation.Slides
    For i = osld.TimeLine.MainSequence.Count To 1 Step -1
        osld.TimeLine.MainSequence(i).Delete
    Next i
    For Each oshp In osld.Shapes
         If oshp.Type = msoPlaceholder Then
            If oshp.Name <> "Content Placeholder 2" Then
                oshp.AnimationSettings.Animate = False
            End If
            If oshp.Name = "Content Placeholder 2" Then
                Set oeff = osld.TimeLine.MainSequence.AddEffect(Shape:=oshp, effectid:=msoAnimEffectAppear, trigger:=msoAnimTriggerOnPageClick)
                oshp.AnimationSettings.AnimationOrder = 1
            End If
        End If
        If oshp.Type = msoMedia Then
            If oshp.MediaType = ppMediaTypeSound Then
                Set oeff = osld.TimeLine.MainSequence.AddEffect(Shape:=oshp, effectid:=msoAnimEffectMediaPlay, trigger:=msoAnimTriggerWithPrevious)
                oshp.Left = 460.7499
                oshp.Top = 250.7499
                oshp.ScaleHeight 0.2, msoTrue
                oshp.ScaleWidth 0.2, msoTrue
                oshp.AnimationSettings.PlaySettings.LoopUntilStopped = True
            End If
        End If
    Next oshp
Next osld
End Sub

更新：希望是最终更新。我想我只需要清除音频的默认动画。我在条件的顶部添加了以下内容：

            If oshp.MediaType = ppMediaTypeSound Then
                oshp.AnimationSettings.Animate = False

PowerPoint编程有点过于复杂。AddeFffect正是您需要使用的：

Sub AdjustTable()
  Dim oSlide As Slide
  Dim oShape As Shape
  Dim oEffect As Effect
  For Each oSlide In ActivePresentation.Slides
    For Each oShape In oSld.Shapes
      If oShape.Type = msoMedia Then
        If oShape.MediaType = ppMediaTypeSound Then
          oShape.Left = 460.7499
          oShape.Top = 250.7499
          Set oEffect = oSlide.TimeLine.MainSequence.AddEffect(Shape:=oShape, _
          effectid:=msoAnimEffectMediaPlay, MsoAnimateByLevel:=msoAnimateLevelNone, _
          MsoAnimTriggerType:=msoAnimTriggerWithPrevious)
        End If
      End If
    Next oShape
  Next oSlide
End Sub

顺便说一句，如果您只检查媒体类型的占位符，您将错过任何插入内容占位符的视频。
