Checking for QuickTime

If you use QuickTime video in your project you might want to check that the end user has an adequate version installed. The following script alerts a user that they need to update the installed version if it's older than version 4 ...

if quickTimeVersion() < 4 then
member("QuickTimeVersion feedback text").text = string("You have an old version of QuickTime and need to install an up-to-date version before you continue.")
end if

Movietime property

Director's Movietime property returns the current position or time (elapsed), of a QuickTime video clip in ticks (60 per second). Movietime can be retrieved and set.

In this equation, movietime is divided by 60 to produce a result in seconds.

member("counter").text = string (sprite(1).movietime / 60 & " seconds elapsed")

MovieRate property

The MovieRate property controls the speed of playback of a QuickTime video sprite.

movierate = 1 ..... Normal speed

movierate = -1 ..... Play backwards

movierate = 2 ..... Double speed

movierate = -8 ..... Fast rewind

... and so on.

QuickTime VR Lingo

Director can act on Hotspots embedded into QTVR movies.

When making a QuickTime VR scene, make a note of the ID numbers of any Hotspots you have created which you want to link to elements in Director.

After you have imported/linked your completed QTVR scene into Director you will need to create 2 scripts.

QTVR scene sprite scripts

Attach this to you QTVR sprite ...

on mouseDown
sprite(the currentSpriteNum).triggerCallback = #HotSpotCallback
end

Put this in a Movie Script ...

on HotSpotCallback me, hotspotID
if hotspotID = 59 then go to frame 20
if hotspotID = 253 then set the stageColor = random(255)
end

In this example 59 and 253 were generated randomly within QuickTime VR Authoring Studio.
