duration (Member)

Usage

-- Lingo syntax
memberObjRef.duration

// JavaScript syntax
memberObjRef.duration;

Description

Cast member property; determines the duration of the specified Shockwave Audio (SWA), transition, Windows Media, and QuickTime cast members.

• When whichCastMember is a streaming sound file, this property indicates the duration of the sound. The duration property returns 0 until streaming begins. Setting preLoadTime to 1 second allows the bit rate to return the actual duration.
• When whichCastMember is a digital video cast member, this property indicates the digital video's duration. The value is in ticks.
• When whichCastMember is a transition cast member, this property indicates the transition's duration. The value for the transition is in milliseconds. During playback, this setting has the same effect as the Duration setting in the Frame Transition dialog box.

This property can be tested for all cast members that support it, but only set for transitions.

To see an example of duration used in a completed movie, see the QT and Flash movie in the Learning/Lingo Examples folder inside the Director application folder.

Example

If the SWA cast member Louie Prima has been preloaded, this statement displays the sound's duration in the field cast member Duration Displayer:

-- Lingo syntax
on exitFrame
   if member("Louie Prima").state = 2 then
      member("Duration Displayer").text = \
string(member("Louie Prima").duration)
   end if
end

// JavaScript syntax
function exitFrame() {
   if (member("Louie Prima").state == 2) {
      member("Duration Displayer").text = 
member("Louie Prima").duration.toString()
   }
}
