createEmptyMovieClip & onclick

[R Verbrugge]

Hello,
I am a beginner in Flash and I'm trying to make a slidebar which loads images from xml data,
this works. However, I want to put an onclick event on it
(in javascript i would make something like this:

_root.bar['diagram'+p].onClick = displaydata(desciption[p]);

function displaydata(content){
textbox1.text = content;
}
)

This is my actionscript code:

<code>
function firstImage() {
for (p=0; p<(total); p++){
var newx = p * 106;
_root.bar.createEmptyMovieClip('diagram'+p,p);
_root.bar['diagram'+p].loadMovie(image[p], 1);
_root.bar['diagram'+p]._x = newx;
_root.bar['diagram'+p]._xscale = 50;
_root.bar['diagram'+p]._yscale = 50;
_root.bar['diagram'+p].onPress = function() {
trace("You pressed me!");
}
}}
</code>
Why does this part _root.bar['diagram'+p].onPress = function() {
trace("You pressed me!");
} not work? and how can I get this to work?


(Flash 8)

Thank you!

Well it works like this:

Code: Select all

bar.onPress = function() {
trace("You pressed me!");
}

So it is something to do with the ['diagram'+p] can you tell me what you are wanting this peice of code to do or why it is there?

I looked around on other pages and I noticed that for loadMovie() you cannot use a 'on (..)' command. instead the suggestion was to duplicate a mc and use the loadMovie() in that dupped movie.
this is what I made and works very nicely!

Code: Select all

function firstImage() { 
_global.fwt = (total * 95) -95;
trace("total pic count ="+total+" total width = "+fwt+"")
for (p=0; p<(total); p++){
_root.bar.redbox.duplicateMovieClip("redbox"+p, p, {_x:(95*p), _y:_root.bar.redbox._y}); 
var datat = (eval("_root.bar.redbox"+p+".duptext"));
var urlinf = (eval("_root.bar.redbox"+p+".url"));
var imgholder = (eval("_root.bar.redbox"+p+".img"));
imgholder.createEmptyMovieClip('diagram'+p,p);
imgholder['diagram'+p].loadMovie(image[p], 1);  
urlinf.text = image[p];
datat.text = description[p];
}
_root.bar._x = 185;
}

Now I wish to add a pre-loader (a little loader bar to show something is being loaded).
How is this done?

There are a few other recent posts about this, but here is a good source for information....

Keep on hitting problems!

Main movie (one frame):

Code: Select all

stop();
function loadXML(loaded) { 
if (loaded) { 
xmlNode = this.firstChild; 
image = []; 
labelt = []; 
total = xmlNode.childNodes.length; 
for (i=0; i<total; i++) { 
image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue; 
labelt[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue; 
} 
fillbar(); 
}  
} 
xmlData = new XML(); 
xmlData.ignoreWhite = true; 
xmlData.onLoad = loadXML; 
xmlData.load("images.xml"); 
function fillbar() { 
_global.fwt = (total * 95) -95;
trace("total pic count ="+total+" total width = "+fwt+"")
for (p=0; p<(total); p++){
_root.bar.redbox.duplicateMovieClip("redbox"+p, p, {_x:(95*p), _y:_root.bar.redbox._y}); 
var datat = (eval("_root.bar.redbox"+p+".duptext"));
var urlinf = (eval("_root.bar.redbox"+p+".url"));
var imgholder = (eval("_root.bar.redbox"+p+".img"));
imgholder.createEmptyMovieClip("picture",p);
imgholder.picture.loadMovie(image[p], 1, {_height:100,_width:100});  
urlinf.text = image[p];
datat.text = labelt[p];
}
_root.bar._x = 185;
}

redbox code:

Code: Select all

on (release){
 _root.title.text = this.duptext.text;
 _root.display.loadMovie(this.url.text);
}

How do I build a preloader in this? I have looked various places and honestly it is utterly confusing! Why can you not simple use:
image[p].getBytesLoaded() ?!!?

[R Verbrugge]

Tried this:
if (imgholder.picture.onLoad = false){
trace('?');
_root.output.text = _root.output.text+"Loading.."+imgholder.picture;
fillbar;
}
else if(imgholder.picture.onLoad = true){
imgholder.picture.loadMovie(image[p], 1, {_height:100,_width:100});
_root.output.text = _root.output.text+" Completed:"+imgholder.picture;
}

no dice.

Did you look at the link to the tutorial I sent you? Or are you wanting to build a preloader for each individual image as it is loaded.

I did look at the link you sent me, I must admit I am quite new to flash although the fillbar() function above I figured out myself, using knowledge I have knowledge of javascript this mixed with looking on the adobe/macromedia AS 2 library produced that code (I dont know how effecient it is) and thats the way it allowed me to actually put an 'on(press)' handler on the dupped mc.

Code: Select all

function fillbar() { 
_global.fwt = (total * 95) -95;
trace("total pic count ="+total+" total width = "+fwt+"")
for (p=0; p<(total); p++){
_root.bar.redbox.duplicateMovieClip("redbox"+p, p, {_x:(95*p), _y:_root.bar.redbox._y}); 
var datat = (eval("_root.bar.redbox"+p+".duptext"));
var urlinf = (eval("_root.bar.redbox"+p+".url"));
var imgholder = (eval("_root.bar.redbox"+p+".img"));
imgholder.createEmptyMovieClip("picture",p);
// Is it here you would preload the image before it goes in the loadMovie() process? or where, how and when?! this is what confuses me!
imgholder.picture.loadMovie(image[p], 1, {_height:100,_width:100});  
urlinf.text = image[p];
datat.text = labelt[p];
}
_root.bar._x = 185;
}

And yes I do wonder if I can show individual image loaded and perhaps total progress.
