Graphics

Hello.  I have a template where I'm trying to change the preview displayed in the XPression MOS plug-in based on whether or not a text box is empty.  The script below I have in On Prepare (ignore the MOS string programming.  That bit is working.).  It's currently not showing the desired preview frame in the plug-in.  I'm sure I'm missing something.  Looking to the community for answers.  Thanks for the help!

'declare variables
dim txtAnimated, txtType, txtStyle, txtBkgd, txtMonth, txtDay, txtBody as xpTextObject
dim director as xpSceneDirector
dim track as xpSceneDirectorTrack
'dim clip as xpSceneDirectorClip
dim Animated, Type, Style as string

'get scene object
Self.GetObjectByName("Animate Graphic", txtAnimated)
Self.GetObjectByName("Select Graphic Type", txtType)
Self.GetObjectByName("Select FS Style", txtStyle)
Self.GetObjectByName("Custom Background Text", txtBkgd)
Self.GetObjectByName("Calendar Title", txtMonth)
Self.GetObjectByName("Calendar Date", txtDay)
Self.GetObjectByName("Text", txtBody)
Self.GetSceneDirectorByName("Preview", director)
director.GetTrackByName("PreviewTrack", track)

'engine.DebugMessage("Selected Style = " & txtStyle.Text, 0)

'set preview frame
If txtBody.Text = "" Then
track.Position = cdbl(40)
Else
track.Position = cdbl(115)
End If

'set type MOS string
If txtType.Text = "Full Screen" Then
Type = ""
Else
Type = "*LIVE VIDEO REQUIRED* | "
End If

'set style MOS string
If txtStyle.Text = "0" Then
Style = "Normal"
Else
Style = "Breaking"
End If

If txtBkgd.Text <> "" Then
Style = right(txtBkgd.Text, len(txtBkgd.Text)-30)
End If

'set animated MOS string
If txtAnimated.Text = "Animated" Then
Animated = "Animated | "
Else
Animated = ""
End If

'engine.DebugMessage("Style = " & Style, 0)

'set MOS string output
If Type = "*LIVE VIDEO REQUIRED* | " Then
Self.MOSDescription = "FS Timeline: " & Animated & Type & txtMonth.Text & " " & txtDay.Text & " | " & txtBody.Text
engine.DebugMessage("FS Timeline: " & Animated & Type & " | " & txtMonth.Text & " " & txtDay.Text & " | " & txtBody.Text, 0)
Else
Self.MOSDescription = "FS Timeline: " & Animated & Type & Style & " | " & txtMonth.Text & " " & txtDay.Text & " | " & txtBody.Text
engine.DebugMessage("FS Timeline: " & Animated & Type & Style & " | " & txtMonth.Text & " " & txtDay.Text & " | " & txtBody.Text, 0)
End If

Preview always comes from the default preview scene director and then you can just move the scene director to a different position.

Here's a script that moves the scene director based on a drop down menu in the plugin and moves the default scene director where you want for different operator previews. 

if text = "1" then
scene.SceneDirector.Position = 0
elseif text = "2" then
scene.SceneDirector.Position = 60
elseif text = "3" then
scene.SceneDirector.Position = 120
end if

Hi Simon, thank you for this.  What if you had multiple scene directors?  Could you change the line to specify which scene director?

scene.SceneDirector.SceneDirectorName.Position = 120

Would the above work as well?

No it doesn't really work like that, what exactly are you trying to achieve and I can probably write something. 

Thanks Simon, I'm not really working on anything, I saw the post and I was just curious. Thank you for the quick reply.

Cheers

Ok the way to do it would be to change which scene director is default in the script so if you ever do need to do it let me know and I can help.
