Problems with loaded movieclips

Maarten_Lierop · April 10, 2006, 6:29pm

Hi there!

I am trying to make mc’s wich are loaded (by data wich stored in a database) on the internet draggable.
This should be easy, but for some reason it won’t work.
My code looks like this:


AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php") 
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            createEmptyMovieClip (AnDo["instance"+i], i)
            loadMovie(AnDo["link"+i], AnDo["instance"+i]);
            setProperty (AnDo["instance"+i], _x, Ando["xpos"+i]);
            setProperty (AnDo["instance"+i], _y, Ando["ypos"+i]);
// this part shopuld make the loaded movieclip draggable, but this won't work
            AnDo["instance"+i].onPress = function () {
                AnDo["instance"+i]._x = mouse_x;
                AnDo["instance"+i]._y = mouse_y;
            }
            trace (AnDo["instance"+i]);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

Please note that for some reason i have to use the setproperty command to put the movieclips on place. When i change the setproperty method to


AnDo["instance"+i].[COLOR=#000084]_x[/COLOR] = Ando["xpose"+i];

it should de exactly the same, but in my case this won’t work anymore.

I’m right now only testing this script in a empty movieclip. Could anybody tell my what’s wrong here?

What dont you just use the drag function? Example:

something.onPress = function(){
   startDrag();
}
something.onRelease = function(){
   stopDrag();
}

Maarten_Lierop · April 10, 2006, 6:46pm

hi!

Thanks fir your time.
Using the startdrag was the first thing i tried. But it didn’t work so i started to look for other ways to get this working. But without succes.

Is there something wrong in the way i am using the variable instancename for the mc’s?

JoshuaJonah · April 10, 2006, 6:51pm

Try this:

AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php") 
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            var dragclip:MovieClip = createEmptyMovieClip (AnDo["instance"+i], i)
            loadMovie(AnDo["link"+i], AnDo["instance"+i]);
            setProperty (AnDo["instance"+i], _x, Ando["xpos"+i]);
            setProperty (AnDo["instance"+i], _y, Ando["ypos"+i]);
// this part shopuld make the loaded movieclip draggable, but this won't work
            dragclip.onPress = function () {
                this.startDrag();
            }
            trace (dragclip);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

Maarten_Lierop · April 10, 2006, 6:57pm

Hi,

the result is :
communicatie succesvol
undefined
undefined

and the movieclips are not draggable

this ‘undefined’ wories me somehow

JoshuaJonah · April 10, 2006, 7:09pm

What did it trace before? and why does the name of the object have to be the value of that array item?

AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php") 
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            var dragclip:MovieClip = createEmptyMovieClip ("dragger"+i, i)
            var link:String = eval(AnDo["link"+i])
            dragclip.loadMovie(link);
            dragclip._x = Ando["xpos"+i];
            dragclip._y = Ando["ypos"+i];
// this part shopuld make the loaded movieclip draggable, but this won't work
            dragclip.onPress = function () {
                this.startDrag();
            }
            trace (dragclip);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

Maarten_Lierop · April 10, 2006, 7:31pm

My previous trace actions did show “undefined”, that’s why i think something is wrong with the names, but i don’t know what.

When i change the trace-action as below


            trace ("dragclip : " + dragclip);
            trace ("name : " + AnDo[instance]);

the result becomes

communicatie succesvol
dragclip :
name : anekdote03
dragclip :
name : anekdote04

dragclip is empty, and anekdotexx is the name, but i also have a varible wich has this name in it, and whan i use this variable, i wouldn’t need the i anymore:


AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php")
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            var dragclip:MovieClip = createEmptyMovieClip (AnDo[instance], i)
            loadMovie(AnDo["link"+i], AnDo[instance]);
            setProperty (AnDo[instance], _x, Ando["xpos"+i]);
            setProperty (AnDo[instance], _y, Ando["ypos"+i]);
// this part shopuld make the loaded movieclip draggable, but this won't work
            dragclip.onPress = function () {
                this.startDrag();
            }
            trace ("dragclip : " + dragclip);
            trace ("name : " + AnDo[instance]);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

with this script the movies are again not draggalbe, and i only see one of them (I’ve got two movies in the database now)

JoshuaJonah · April 10, 2006, 7:38pm

did you copy and paste my above code?

Maarten_Lierop · April 10, 2006, 7:42pm

yes i did, the movieclips did not show up at all
output was:

communicatie succesvol
undefined
undefined

JoshuaJonah · April 10, 2006, 7:49pm

try traceing it more specifically to see where it looses it’s value:

AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php") 
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            var dragclip:MovieClip = createEmptyMovieClip ("dragger"+i, i)
            trace (dragclip+" has been created")
            var link:String = eval(AnDo["link"+i])
            trace ("Link: "+link)
            dragclip.loadMovie(link);
            trace (dragclip)
            dragclip._x = AnDo["xpos"+i];
            trace (dragclip._x)
            dragclip._y = AnDo["ypos"+i];
            trace (dragclip._y)
// this part shopuld make the loaded movieclip draggable, but this won't work
            dragclip.onPress = function () {
                trace ("you clicked")
                this.startDrag();
            }
            trace (dragclip);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

stringy · April 10, 2006, 7:52pm

You need to make sure the movies are loaded before using function

dragclip.onPress = function () {
                this.startDrag();
            }

Maarten_Lierop · April 10, 2006, 8:03pm

ouptu for your script is:
communicatie succesvol
has been created
Link:
undefined
undefined
undefined
undefined
has been created
Link:
undefined
undefined
undefined
undefined

I tried to implement the trace actions also to your first script because in that script the mc’s did show up


AnDo = new LoadVars()
AnDo.load("http://www.maartenlierop.nl/janv/janv.php")
AnDo.onLoad = function(succes){
    if(succes){
        trace("communicatie succesvol");
        for(var i=0; i<this.cant; i++){
// loading the movieclips, and put them on their place
            var dragclip:MovieClip = createEmptyMovieClip (AnDo["instance"+i], i)
              trace (dragclip+" has been created")
            loadMovie(AnDo["link"+i], AnDo["instance"+i]);
              trace ("Link: "+link)
              trace (dragclip)
            setProperty (AnDo["instance"+i], _x, Ando["xpos"+i]);
            setProperty (AnDo["instance"+i], _y, Ando["ypos"+i]);
              trace (dragclip);
            dragclip.onPress = function () {
                this.startDrag();
                trace ("you clicked")
            }
              trace (dragclip);
        }
    }else{
        trace("communicatie niet succesvol");
    }
}

the output is here not much more hopegiving:
communicatie succesvol
has been created
Link:
undefined
undefined
undefined
has been created
Link:

thanx Stringy, didn’t think we’d have to break out a function

Maarten_Lierop · April 10, 2006, 8:19pm

For Stringy:

I think it goes wrong far before the startdrag command is assigned.
I tried to place the startdrag inside an onload together with a trace “movie loaded.” But although the movies showed up on screen, the trace Movies loaded never showed up.

Maarten_Lierop · April 10, 2006, 8:25pm

oke, i think i understand what you did (but this is starting to look far more complicated).
But still; in my window i do not see the mc’s
do they show up on your screens?

stringy · April 10, 2006, 8:27pm

hmm seems to work ok for me-maybe i am missing something
This just uses code by Defective + my checkload thingy

Thank you guys! it works!:thumb:
I spent four days changing this code again and again, but it finaly works!
I need it for my final project on art school, When i’ve finished my project i will show it to you (takes a couple of weeks)
