hi all,
basically I’m looking for the best way to preload slides for a slideshow. The application isn’t really a slideshow app, its a video player that listens for cuepoints based on the stream time. If a cuepoint is triggered a new slide (1.swf … 199.swf) is loaded into a container.
Since some of the cuepoints are only seconds apart, I am looking for a way to preload all the slides in the background and then show the right slide at the right time. Since the user can skip into the video, I need to be able to always show the right slide at that time.
To explain this: IN AS2 the player worked this way.
- a slides.swf file was loaded that contained all the slides 1-200 on sepearte frames.
so in the app when a cuepoint was fired I just said:
gotoAndPlay(cuepoint.name) where name was a number from 1-200.
In AS3 I would now like to load seperate slide files 1.swf 2.swf - 200.swf.
how do target for example 60.swf if that cuepoint is fired? Do I need to do displaylist stacking swapchild stuff or what? and how do i do that?
To Consider:
- Some of the presentations have 200+ slides (20-60k each). --> can I actually preload them all without performance problems.

[*]maybe only preload 5 slides from current position (needs to be plus minus 5) since you can skip back and forward. And you can jump withing the video.

2. How do I do this. My cuepoints xml will have all the slide urls etc, but how do I load all of the slides and then bring them to the front when needed.
Thx in advance for any suggestions
EDIT: ok found something.
I just load all the images sequentially, --> Event.COMPLETE --> load next slide.
then when I reach a cuepoint and the loader loads the slides url it seems to be cached already and thereby is preloaded.
nor sure if this is a good way to do it.
