Hi, Kevin/ other experts:
I'd like to build an extended application based on your simple tag search
example.
The temporal goal is to show, say 500 photos of specific tag from Flickr,
with each photo showing 5 seconds on the screen.
The first problem is it seems that sometimes(?) those requested results are
the same.
For example, when I call _flashr.photosSearch({tags:dog, per_page:10}) 50
times, with requesting 10 photos each time,
the 10 photos returned remain the same in different runs. How could I
prevent this situation?
Because I want to show different photos over time, not repeating the same
photos.
If I request all 500 photos and save those in a local array in Flash, then
it may be too heavy for Flash? (I request normal size photos, not just
thumbnails)
The second question is how to make a photo staying shown for 5 seconds and
then move onto the next one?
I have tried to use the following code (in this example, I only request one
photo each time and there are 4 requests in total)
function onPhotosSearch(rs:ResultsSet)
{
var thisPhoto:Photo = rs.photos[0];
var show_interval:Number = setInterval(showImage, 5000, thisPhoto);
//showing the current photo for 5 seconds
if (_numRequests < 4)
{ doSearch(SEARCH_TAG); //searching for next
photo
}
else
{
trace("\n Requesting number is out of limit");
clearInterval(show_interval);
}
}
I knew something is wrong because it didnot work the way I want, but I
don't know how to fix it.
I realized that I passed the same "thisPhoto" in setInterval(), so in every
5 seconds it shows the same photo.
(for now I only know 2 approaches to show something for certain duration-
onEnterFrame and setInterval )
So, the question will be is it possible to pass a dynamic variable to
setInterval()?
Or I am in the wrong direction to make those photos shown in slideshow
presentation?
(Maybe using some for-loop to read a photo from an arrary each 5 seconds,
but the question remains the same-
how to let some action stays for certain duration?)
Please guide me a way. Thanks a lot.
Gloria
