preload 10 jpgs 1

[Bignewbie]

Hi guys,

I need help. I have 10 MC named "preloadMov1" to "preloadMov10" on the root of my swf. I have to preload 10 jpgs in those MCs. Any idea on how to do this?

Please help!

This will load the jpgs into the clips (code on the main timeline):

for(var i=1;i<=10;i++){
this['preloadMov'+i].loadMovie('images/jpg'+i);
}

If you want a real 'preload' effect you could have the clips offstage as the images load in and bring them on stage as you need them.

To get real control over the images regarding placement and sizing it's best to load them in to 'holder' clips (loading directly into a clip as above will wipe everything else in the mc). A holder clip has a second empty clip nested inside it that holds the image as it's loaded in and then you can script the 'parent' clip more easily, and maybe have other graphic elements like a border etc. I usually add an empty clip called 'loadPoint' so I know where I am:

for(var i=1;i<=10;i++){
this['preloadMov'+i].loadPoint.loadMovie('images/jpg'+i);
}

wangbar,

for(var i=1;i<=10;i++){
this['preloadMov'+i].loadMovie('images/jpg'+i);
}

the above code worked wonderfully, and your loadPoint idea is great! I worked out real fine, and i really didn't have much trouble about resizing it.

Another question, is there any way to know if the jpgs are done loading? it's like this: I show all 10 (thumbnail size, hence the resizing), then I show them one by one, in their original sizes, my question is, is there any way to know if all jpgs have been shown in the first part? I need some trigger for the second part where i show them one at a time.

You can use getBytesLoaded() and getBytesTotal() for jpgs exactly as you can for normal .swf movies so it's basically like any other preloader. So you could either cycle through each clip like this:

checkAllLoaded = function () {
//checks through each clip to see what its status is
	for (var i = 1; i<=10; i++) {
		clip = this['preloadMov'+i];
		if (clip.getBytesLoaded()<clip.getBytesTotal()) {
			return false;
		}
	}
	return true;
};
//
this.onEnterFrame = function() {
//see if everything has loaded, keep looping if it hasn't
	loadedOk = checkAllLoaded();
	if (loadedOk) {
		this.onEnterFrame = null;
		//go and do rest of movie
	}
};

...or attach an enterFrame event to each clip as it loads. I haven't checked this code actually running but it should work okay.
