Hi there.
I started a tutorial about creating a flash slideshow. This is the as2 code:
[INDENT]import mx.transitions.Tween;
import mx.transitions.easing.*;
var myShowXML = new XML();
myShowXML.ignoreWhite = true;
myShowXML.load("slideshow.xml");
myShowXML.onLoad = function() {
_root.myWidth = myShowXML.firstChild.attributes.width;
_root.myHeight = myShowXML.firstChild.attributes.height;
_root.mySpeed = myShowXML.firstChild.attributes.speed;
_root.myImages = myShowXML.firstChild.childNodes;
_root.myImagesNo = myImages.length;
total = myShowXML.childNodes.length;
createContainer();
callImages();
};
function createContainer() {
_root.createEmptyMovieClip("myContainer_mc",_root.getNextHighestDepth( ));
myContainer_mc.lineTo(_root.myWidth,_root.myHeight);
myContainer_mc._x = (Stage.width-myContainer_mc._width)/2;
myContainer_mc._y = (Stage.height-myContainer_mc._height)/2;
}
function callImages() {
_root.myMCL = new MovieClipLoader();
_root.myPreloader = new Object();
_root.myMCL.addListener(_root.myPreloader);
_root.myClips_array = [];
_root.myPreloader.onLoadStart = function(target) {
_root.createTextField("myText_txt",_root.getNextHighestDepth(),0,0,100 ,20);
_root.myText_txt._x = (Stage.width-_root.myText_txt._width)/2;
_root.myText_txt._y = (Stage.height-_root.myText_txt._height)/1.08;
_root.myText_txt.autoSize = "center";
};
_root.myPreloader.onLoadProgress = function(target){
_root.myText_txt.text = "Loading.. "+_root.myClips_array.length+"/"+_root.myImagesNo+" Completed";
}
_root.myPreloader.onLoadComplete = function(target) {
_root.myClips_array.push(target);
target._alpha=0;
if (_root.myClips_array.length == _root.myImagesNo) {
myText_txt._alpha=0;
moveSlide();
myShowInt = setInterval(moveSlide, (_root.mySpeed*1000)+1000);
}
}
for (i=0; i<_root.myImagesNo; i++) {
temp_url = _root.myImages*.attributes.url;
temp_mc = myContainer_mc.createEmptyMovieClip(i, myContainer_mc.getNextHighestDepth());
_root.myMCL.loadClip(temp_url,temp_mc);
}
}
function moveSlide() {
current_mc = _root.myClips_array[_root.target_mc];
new Tween(current_mc, "_alpha", Strong.easeOut, 100, 0, 1, true);
_root.target_mc++;
if (_root.target_mc>=_root.myImagesNo) {
_root.target_mc = 0;
}
next_mc = _root.myClips_array[_root.target_mc];
new Tween(next_mc, "_alpha", Strong.easeOut, 0, 100, 1, true);
}
//I have created 2 buttons - NEXT with instance name:next_btn and PREV
//with instance name:prev_btn and these are the on(release) functions:
previous_btn.onRelease = function() {
prevImage();
};
next_btn.onRelease = function() {
nextImage();
};
[/INDENT]
The images load from xml file and change through moveSlide function.
And now i need to create those 2 new functions in order to give the user the opportunity to change the images by him/herself.
I found somewhere a piece of code about this kind of functions:
[INDENT]p = 0;
function nextImage() {
if (p<(total-1)) {
p++;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
picture_num();
}
}
}
function prevImage() {
if (p>0) {
p--;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
picture_num();
}
}
function picture_num() {
current_pos = p+1;
pos_txt.text = current_pos+" / "+total;
}
[/INDENT]
The link i got these functions is this:

How can i adjust these functions to my slideshow?
P.S. Sorry, but i am not an as2 expert but any help is welcomed.
Thanks in advance
