Has anyone figured a way to determine if a loadMovie is complete?
I've nearly gotten a nice slide show movie going that dynamically reads in JPG's and fades them up and down.
My problem is knowing if It's finished loading the jpg into the movie clip so I can then scale it in via a function.
Also has anyone had any issues with certain JPG's just plain not loading via loadMovie?
If I can every get this darn slideshow finished I'll have some nice code to share with ya'll.
Too slow! Got it.
movie.getTotalBytes
movie.getBytesLoaded
just like preloaders.
Onward then........
Amazing how complicated this has become. THe start script is 111 lines so far.
Cheers to the man who answers his own question. :yarr:
yeap yeap harry ! :grouphug:
this is an interesting question.
wow. i like donuts
Ok I'm getting fed up with this!
I've spent a good deal of time on a movie that works in preview but just won't work on export. Simple script stuff.... Apparently (took hours to figure out the problem) getBytesLoaded() for loaded movie clips is not reported on export. Anyone else confirm this?
I was using it thus:
PHP Code:function isLoaded(clip){
if (clip.getBytesLoaded()<clip.getBytesTotal()){
return false
}else{
return true
}
}//end isLoaded function
My Start Script
My Sciprt that loads the array of imagesPHP Code:showReady=false
done=false
display=false
curslide=0
firsttime=true//so we react differently first time in show loop
a_rate=2 //speed to fade smaller is slower
//title="3dfa Slideshow"
x=1
//make array to hold images
slides=new Array
//set background color
//may get this from data as well
bg=rgb(80,192,255);
drawBg(bg,350,350)
//Url to PHP file that delivers list of slides
//slideURL="http://bretlanius.com/Photos/3dfaslideshow.php"
//& Get the list
//this.loadVariables(slideURL,"GET")
//Test line below for testing local without loading from server
images="maxshoot.jpg|1996 Olymics.jpg|Bret with SR.jpg|Disney Selma Lord Selma.jpg|False River2.jpg|FATS in Holland.jpg|GulfWar_Promos.jpg"
function fileLoaded(clip){
return clip.getTotalBytes>clip.getBytesLoaded
}
function processList(images){
//Parse out the data from the URL
imagearray=new Array
pt=images.indexOf("|",0)//| is our seperator we search for the first one
imagearray[0]=images.substr(0,pt)//Get it
start=pt+1//Now we start looking for the next one
idx=1
while (pt>0){//Loop until we are at the end of the list
pt=images.indexOf("|",start)
if (pt>=1){
imagearray[idx]=images.slice(start,pt) //found next |
}
else{
imagearray[idx]=images.slice(start,images.length)//Last entry no | so pt=0
}
start=pt+1
idx++
}//end while
return imagearray;
}//End of processList Function
function scaleImage(im,h,w){//only scales if bigger than movie
//Add in future scale up as well
//scale slide it to fit screen
//first make sure it's full size to start with
im.scale.x=100
im.scale.y=100
//get rectangle
size=im.getBounds()
//Now calculate scale needed to fit 350 width
if (size.xMax>size.yMax){
if (size.xMax>w){//yes
pscale=w/size.xMax
im.scale.x=(im.scale.x*pscale)-5//minus 5 is so that it's slightly smaller than the width of movie
im.scale.y=(im.scale.y*pscale)-5
}
}else{
if (size.yMax>h){//yes
pscale=h/size.yMax
im.scale.x=im.scale.x*pscale-5
im.scale.y=im.scale.y*pscale-5
}
}
//find centers
size=im.getBounds()
icw=size.xMax/2 //center of image
ich=size.yMax/2
mcw=w/2 //center of screen
mch=h/2
//center image
im.x=mcw-icw
im.y=mch-ich
}
function drawBg(color,width,height){
black=rgb(0,0,0)
root.beginFill (color,100)
root.lineStyle(8,black,100)
root.moveTo(0,0)
root.lineTo(0,width)
root.lineTo(height,width)
root.lineTo(height,0)
root.lineTo(0,0)
root.endFill()
}
function isLoaded(clip){
if (clip.getBytesLoaded()<clip.getBytesTotal()){
return false
}else{
return true
}
}//end isLoaded function
And the script to show themPHP Code:if (images.length>=1 && done==false){
done=true
imagearray=root.processList(images);
totalimages=imagearray.length
//**********************************
for (x=0;x<totalimages;x++){
slides[x]=root.createMovie()
slides[x].alpha=0
slides[x].loadMovie(imagearray[x])
test=imagearray[x]+" "+slides[x].getBytesTotal()
while (!root.isLoaded(slides[x])){
timeout++//this is just in case we hang here too long
if (timeout>50000){
element ("error text").show()
showReady=false
break
}
}//Dangerous
}//end for
//**********************************
//Ok All loaded now scale them
for (x=0;x<totalimages;x++){
root.scaleImage(slides[x],350,350);
}
showReady=true
element ("loading").hide()
}//end if
PHP Code:if (showReady){
if (firsttime){
firsttime=false
slides[curslide].alpha=100
}//end if firsttime
trace (curslide)
if (slides[curslide].alpha==0){
if (curslide<totalimages-1){
curslide++
}else{
curslide=0
}
}
slides[curslide].alpha=slides[curslide].alpha-a_rate
if (curslide<totalimages-1){
slides[curslide+1].alpha+=a_rate
}else{
slides[0].alpha+=a_rate
}
}
I'm open to suggestions. This all works except that I cannot scale the images untill they are done loading.
Oh and the Server PHP is
PHP Code:<?php
function directory($dir,$filters){
$handle=opendir($dir);
$files=array();
if ($filters == "all"){
while(($file = readdir($handle))!==false){$files[] = $file;}}
if ($filters != "all"){
$filters=explode(",",$filters);
while (($file = readdir($handle))!==false) {
for ($f=0;$f<sizeof($filters);$f++):
$system=explode(".",$file);
if ($system[1] == $filters[$f]){$files[] = $file;}
endfor;
}
}
closedir($handle);
return $files;
}
$images=directory(".","jpg");
//print_r($images);
$imagelist=implode('|',$images);
echo "&images=".$imagelist;
?>
I made a little script for my own. but I cant load a pic from the internet (http://...). only if I place it in the movie directory on my pc 3dfa loads it. but only in preview.
this is my code:
this won't work.PHP Code:pic=this.createMovie();
pic.loadMovie ("http://www.ejected.de/images/example2.jpg");
I think the problem there is just that it can ONLY load local files. So the swf must be local to the jpg loaded. Try that and remove everything except the filename.
i uploaded the movie and a pic to the root dir of my webserver. this don't work.
PHP Code:pic=this.createMovie();
pic.loadMovie ("example2.jpg");
odd I know it works
http://bretlanius.com/photos/movie_241.html
is doing just that. It is part of the testing for the slideshow I was doing.
By the way for those interested I've reported this problem to Rob, but so far have heard nothing back from him. He used to reply to me about bugs and status of updates and such, even talked about me being the moderator on this board but I haven't heard from him in quite a long time now. I can't believe after all this time that I'm looking at other programs to fill my needs.
please don't leave 3dfa community bret. we all need you! ;)
ok go here: http://www.ejected.de/images/
and click on movie.swf
the example2.jpg is in the same dir.
i added this start script:
i uploaded the .movie alsoPHP Code:pic=this.createMovie();
pic.loadMovie ("example2.jpg");
must be the jpg. I had one that just wouldn't load no matter what.
But I changed the filename only and exported your example to
http://bretlanius.com/photos/movie.html
and it works fine
as for leaving I don't want to I've been a strong supporter of the product, but I feel like the unpaid support team for the product and therefore have no one to turn to when I need help. This slideshow is a good example. I have a couple days spent on this and I need it for a couple of websites that we are building and here I am stymied, worse yet I don't know if the way I used getBytesLoaded is even ok to do , nor is there anyone to ask if there is a way to determine if a jpg has finsihed loading. This is important as the getBounds function will reurtn 0's until it is, then it returns the proper size so I can scale the images to fit the screen. I re-wrote the core code for this 3 times. And every time I had a problem I have to wonder is it something I did wrong or is it another bug, so I then spend more time testing the concept of what I'm trying to do in another simpler movie.
HOWLY COW THATS IT
I can test the getBounds till it retuns a positive number!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
That just might work.....
Ohhh gotta go, have a theory to test.
Hi Blanius
Please check on this tutorial:
http://actionscript-toolbox.com/samplemx_loadjpg.php .
As getBytesLoaded don't work on Flash, the developer use _width > 0.
I never work jpg load system, so i donīt know if it work, but probably this tutorial can help you.
Rui
Almost have it now
As reported by lopez1_de and confirmed by me some jpeg's just don't show.. I have no idea why.
I still cannot successfully scale my images as I cannot tell if they are loaded but otherwise it's working
http://bretlanius.com/photos/slideshow.html
Turns out getBytesLoaded is working on export it just gives wierd results in preview and before the image is loaded, so I get odd results when the clip is first created. Soooo I have to figure a consistent way of testing the value before scaling..
Still something wierd going on though
Hi Blanius
I do not know if this is the problem, but on actionscript tutorial they wrote "To load an external jpg into a Flash MX movie, you need only three things: a non-progressive jpg, a blank movieclip to load it into, and a command in your movie to do the loading".
NON - PROGRESSIVE JPG.
I repeat, i don't know if this is the problem.
Bibi
Rui
non-progressive is probably the problem with the ones that don't load.
Right now I just so happy it's working. There is still issues with testing if a jpeg is loaded though.
bret, I can't see any picture in your example! (http://bretlanius.com/photos/slideshow.html)
probably has to do with load time. If the slideshow starts before the images are fully loaded they get scaled to a negavtive number and cannot be seen, try refreshing the browser. I'm still looking at this.
I'd use scenes and loop until they where loaded, but scenes don't work right either.
OK I think it's all working together now. Including waiting for ALL slides to load.
Try it out again. If I don't find any more problems I'll release the movie file to you all
Now it works! Good job Bret. Thank you for sharing the source. :)
