Question

Dynamically load JPEG into movie clip (via param) and make draggable, resizeable, and more...

Asked by: DJMikeAZ



I'm using Flash 8 Pro. I'm pretty new to ActionScript 2.0 but am under the impression that this should be fairly simple.

What I would like is a method of loading a series of JPEG images (assumably passed in via a param) into individual movie clips. Then, basically enabling the user to drag them around, resize them, adjust the alpha channel, etc.

If possible, this will eventually be a larger scale web-based slideshow/image comparison utility-- but for now, I am mostly looking to build a very simple, very basic working prototype to demonstrate to the project managers that something like this could be implemented....call it conceptual research.

The code I have so far is to load one single image into a movie clip, and even that doesn't work. The image loads fine but I cannot drag it.

========================

// NOTE: assume this is nested in a for loop

_root.createEmptyMovieClip("placeHolder"+i, _root.getNextHighestDepth());
_root["placeHolder"+i]._x = 100*i;
_root["placeHolder"+i]._y = 25;
_root["placeHolder"+i]._xscale = 50;
_root["placeHolder"+i]._yscale = 50;
_root["placeHolder"+i].loadMovie("images/2004.jpg")      
_root["placeHolder"+i].onPress = function() {            
      this.startDrag(true);
};
_root["placeHolder"+i].onRelease = function() {
      stopDrag();
};
========================

Anyway, as I mentioned above, the goal here is to dynamically load the images, and make them draggable, resizeable, alpha channel adjustable. Eventually, I would like to research adjusting image contrast and color channels as well but that is not of immediate importance. Sample code or a very relevant link to a tutorial is preferred (although I like sample code better).

Thanks in advance,

- Mike

Not really actionscript for the beginner, looks nice!

Should work as well.

What I did get working is the following script (with 1 JPG!):

i = 1;
_root.createEmptyMovieClip("placeHolder"+i, 20);
_root["placeHolder"+i]._x = 100*i;
_root["placeHolder"+i]._y = 25;
_root["placeHolder"+i]._xscale = 50;
_root["placeHolder"+i]._yscale = 50;
_root["placeHolder"+i].loadMovie("fotos/image1.jpg");
_root.onMouseDown = function () {
      _root["placeHolder"+i].startDrag(false);
}
_root.onMouseUp = function () {
      stopDrag() ;
}

Will try some other scenarios too.

I found the following script which is totally different and not usefull for early version of Flash MX. The swap-depths solution is clever. With drag-drop you dragmovie must always be on top for it to work 100%... although its not a showstopper if it isnt on top.


var mcArr = new Array();
var mcl:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
mcl.addListener(myListener);
var y = -150;
for(i = 0; i < 3; i++){
      mcArr[i] = this.createEmptyMovieClip("clip"+i, this.getNextHighestDepth());
      mcl.loadClip("images/2004.jpg", mcArr[i]);
}
var highPoint = this.createEmptyMovieClip("high", this.getNextHighestDepth());

myListener.onLoadInit = function(target_mc){
      target_mc._x = 10;
      target_mc._y = 10;
      target_mc._visible = true;
      target_mc.onPress = function(){
            this.swapDepths(highPoint);
            startDrag(this);
      }
      target_mc.onRelease = function(){
            this.swapDepths(highPoint);
            stopDrag();
      }
};
