hi all,
i’m modifying the photo gallery tutorial on this sit to suit me and i’ve got some questions on how best to modify it and also on how it works.
-
Firstly if I’m using the ten images supplied in the tutorial and i activate the SWF to load tutorial, do the images load 1 at at time or will i wait for the ten to load at once?
-
in either case, if say images load 1 by 1 and the image is 50K
how can i add a pre-loader to each image so I’m not staring at a blank screen waiting for each image to pop up? -
also, how can I modify the code to make it go to image 4 first,
for eg, I have 10 thumbnail images in my main SWF, i want to click on thumb 5 button so it goes to image 5 in the gallery SWF instead of image 1 which it is doing, and then have the forward button go to image 6 etc, and the back button go to image 5 etc…
code…that’s used
/*
i wrote this code, but you can use and abuse it however you like.
the methods are defined in the order which they occur to make it
easier to understand.
*/
// variables ------------------------------------------
// put the path to your pics here, include the slashes (ie. “pics/”)
// leave it blank if they’re in the same directory
this.pathToPics = “animation/”;
// fill this array with your pics
this.pArray = [“image0.jpg”, “image1.jpg”, “image2.jpg”, “image3.jpg”, “image4.jpg”, “image5.jpg”, “image6.jpg”, “image7.jpg”, “image8.jpg”, “image9.jpg”, “image10.jpg”];
this.fadeSpeed = 20;
this.pIndex = 0;
// MovieClip methods ----------------------------------
// d=direction; should 1 or -1 but can be any number
//loads an image automatically when you run animation
loadMovie(this.pathToPics+this.pArray[0], _root.photo);
MovieClip.prototype.changePhoto = function(d) {
// make sure pIndex falls within pArray.length
this.pIndex = (this.pIndex+d)%this.pArray.length;
if (this.pIndex<0) {
this.pIndex += this.pArray.length;
}
this.onEnterFrame = fadeOut;
};
MovieClip.prototype.fadeOut = function() {
if (this.photo._alpha>this.fadeSpeed) {
this.photo._alpha -= this.fadeSpeed;
} else {
this.loadPhoto();
}
};
MovieClip.prototype.loadPhoto = function() {
// specify the movieclip to load images into
var p = _root.photo;
//------------------------------------------
p._alpha = 0;
p.loadMovie(this.pathToPics+this.pArray[this.pIndex]);
this.onEnterFrame = loadMeter;
};
MovieClip.prototype.loadMeter = function() {
var i, l, t;
l = this.photo.getBytesLoaded();
t = this.photo.getBytesTotal();
if (t>0 && t == l) {
this.onEnterFrame = fadeIn;
} else {
trace(l/t);
}
};
MovieClip.prototype.fadeIn = function() {
if (this.photo._alpha<100-this.fadeSpeed) {
this.photo._alpha += this.fadeSpeed;
} else {
this.photo._alpha = 100;
this.onEnterFrame = null;
}
};
// Actions -----------------------------------------
// these aren’t necessary, just an example implementation
this.onKeyDown = function() {
if (Key.getCode() == Key.LEFT) {
this.changePhoto(-1);
} else if (Key.getCode() == Key.RIGHT) {
this.changePhoto(1);
}
};
Key.addListener(this);
