The PreloaderMost users still have modems so we have to preload the slides to have them ready when buttons are pushed. We make a preload function here
//function to preload slides
function loadAll(firstSlide,lastSlide,slideName,introSlide){
for (j=1;j<=lastSlide;j++) {
//use duplicateMovieClip here instaed of createEmptyMovieClip
duplicateMovieClip (_root.slideHolder, "pic_"+j, j);
//make the slides invisible not to see the loading
setProperty ("pic_"+j, _alpha, (0));
loadMovie(slideName+j+".jpg","pic_"+j);
//load slides into slideholder_1 and make it invisible not to see the loading
loadMovie(slideName+j+".jpg","slideHolder_1");
setProperty("slideHolder_1",_alpha, (0));
//here we load an introduction slide
loadMovie(introSlide,"slideHolder");
}
}
To monitor the loading we attach the following script to slideHolder_1.
onClipEvent(enterFrame){
if(this._url != _root._url && !loaded) {
// calculate size of pics in kilobytes
var kilobytes = Math.ceil(this.getBytesTotal()/1024);
// calculate percent loaded
var percentLoaded = Math.ceil((this.getBytesLoaded()/this.getBytesTotal()) * 100);
// show loading message
_root.percentOutput = "loading " + percentLoaded + "% of " + kilobytes + "k";
//show text loading slides
_root.loadText.gotoAndPlay("play");
if(percentLoaded == 100){
//loading terminated
loaded = true;
_root.percentOutput = "Ready";
_root.loadText.gotoAndStop("stop");
}
}
}
