I am trying to get an interactive videodisc presentation up and going. I
purchased the Voyager Videostack by Voyager tm, and successfully used it
in the past with HC 1.2.5. When I attempt to install resources into my
resource stack with it's installer, I get the error:
The resource to be copied wasn't found in the source.
The resource stack seems to be choking on the line:
vid control (something like that ...)
I suppose I could make a copy of the installer stack, delete the cards,
etc., and unnecessary resources, and use it as my resource stack. If
anyone has had any dealings with this, please forward your experience.
(I called Voyager, and they're coming out with a 2.0-compatible version
in about a month).
ALSO, does anyone know of a different way to invoke a handler by reading
a video frame from a laserdisc? The way I've tried uses some code in
the Voyager Videostack tm:
global EndFrame -- this is at top of handler-apparently referencing this
-- elsewhere
-- play a video segment from whatever to 12345 (videoframe)
...
put empty into LastFrame
put 12345 into EndFrame -- my code, where 12345 is the last frame
repeat forever
... -- some code deleted (used to abort with a mouseclick
video getframe
get the result
if it = EndFrame or it = LastFrame then exit repeat
put it into LastFrame
End repeat
video, stop -- my code, to make the picture turn blue AFTER the last
-- video frame (without waiting for the last frame, the blue
-- comes on the video right away
Unfortunately, the loop never exits. Also, I was hopefully for another
solution, since a 7 minute video segment plays, and this repeat loop
would have to run the entire time. I don't know if there is any other way
of getting a video frame, other than continuous polling. Any ideas? thanks
