If there is no url found doing something else

**Rkokie** · 12-07-2010, 07:44 AM

Hey,

I'm working on this project which loads texts and images from xml,
the texts and images are loaded in and then put in arrays.

But when I don't put an url in the xml it will say url not found and just display nothing, so this is what I'm trying to get, A way to like if it can't find one of the urls to just skip it and move the text loaded over that spot. But I just can't seem to get it right, I'm sort of a beginner so srry if this is a stupid question I just can't find how to fix this and can't find any good fix for it so I hope you guys know something.

Greetings, Roger

both Loader and URLLoader dispatch events when there's an error like that - you can assign handlers to do stuff when those events are fired.

post the code you're using now.

It probably looks noobish since I used a tut and extended it alot.

So in my xml I have about 8 urls listed, it gets loaded into flash, stored in an array and played one by one, but since I wanna leave one away, I have work around that , thanks for your help already, this is the full script

so you're basically just worried about images, right? if an image isn't found, then skip that step entirely? no textfields or anything, just continue processing as if that node didn't exist... correct?

**Rkokie** · 12-07-2010, 06:18 PM

Yeah but next each image is a textfield and I want that to move to cover the area where the image should be, which would be no problem If this is fixed with a event listener i guess.

**moagrius** · 12-07-2010, 06:52 PM

you could so something like this:

PHP Code:


my_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, missingImage, false, 0, true);
//  later...
private function missingImage(event:IOErrorEvent):void{
  // do whatever...
}

that'd be right around where you're assigning the complete listener to my_loader in your loop.

also, just some advice - you don't need to re-instance those fonts during each iteration - i'd take the font instantiation out of the loop... also, you could break down that @FONTFAMILY / @AUTHORFONT if stack to a switch statement, or better yet a map... e.g.,

PHP Code:


// outside the loop
var fontMap:Object = {
    "Imact" : F1.fontName,
    "Times New Roman" : F2.fontName,
    ... etc
}

// in the loop
my_format.font = fontMap[my_images[i].@FONTFAMILY];
my_Aformat.font = fontMap[my_images[i].@AUTHORFONT];

**Rkokie** · 12-08-2010, 08:04 AM

wow thanks Am gonna try that and I'll update you with the results!

**Rkokie** · 12-08-2010, 11:37 AM

I can't seem to find a place for the loader code to work any suggestions? srry for the beginner questions >_<

Edit:
The font thing worked great thanks!

**moagrius** · 12-08-2010, 11:54 AM

put the my_loader.contentLoaderInfo.addEventListener on the line before or after the existing line of the same...

PHP Code:


var my_url:String = my_images[i].@URL; 
var my_loader:Loader = new Loader(); 
my_loader.load(new URLRequest(my_url)); 
my_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, missingImage, false, 0, true);
my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete); 
my_loaders_array.push(my_loader);

then put the function (missingImage) with the other private/public functions.

**Rkokie** · 12-09-2010, 06:15 AM

srry but I don't have any other private/public functions and if I use yours with the private in front of it it gives me an error:
Scene 1, Layer 'actionscript', Frame 1, Line 192 1013: The private attribute may be used only on class property definitions.

I have tried to put it this way now:
function missingImage(e:IOErrorEvent):void
{
my_textX_array[my_playback_counter].x -150;
}

just above the onComplete function.

Edit:
I have just checked for private/public functions, but I'm not using a package, should I or can I just keep it like this and not use them?

**moagrius** · 12-09-2010, 09:14 AM

if you're not using classes, you don't need private/public - what you have for the missingImage function is fine.

but - something else is going to give you a problem. that event is going to fire after some time has passed - just like the COMPLETE event fires after everything else in that loop happens - which will be after all the other code executes. so my_playback_counter is going to be the very last value it was set at, for each error event that fires. you need to find a way to match the erroring instance to the textfield you want to move.

**Rkokie** · 12-09-2010, 09:37 AM

wow and this is quite complicated right? I just can't find a way to make it move that textfield that is on the same slide as the no url image, sorry to be such a hardass but I've been working on this for a few hours already and I can't get it clear.

**moagrius** · 12-09-2010, 11:35 AM

i obviously don't have the rest of your package, so i can't test this, but in theory it should work. the changes i made are marked with a comment starting like so:

Edit:
maybe a translator can give a more accurate translation for the error:

ReferenceError: Error # 1069: Can not find the x property of Number and there is no default value.
at My_Slideshow_fla::maintimeline/missing image()

apparently my_textX_array is an array of numbers... you were trying to assign the x value, so i assumed it was display objects.

try changing this line in the missingImage function:

PHP Code:


my_textX_array[position].x -= 150;

to this:

PHP Code:


my_textX_array[position] -= 150;

again, that's assuming you want to reduce the current value by 150, which is what it looked like you wanted. if you want to set it to 150, change -= to =

offcourse, its a value not a coördinate, thanks man. but now somehow when I started up flash today it just doesn't load the texts etc. anymore

I have just tried to put a valid url in for the image and it works then, the IOErrorEvent makes it just skip it and continue loading the rest right? somehow it doesn't load the rest of the texts so it keeps on loading

**Rkokie** · 12-10-2010, 10:10 AM

Any Idea what to do now? :/

**moagrius** · 12-10-2010, 10:39 AM

it's hard to debug blind. can you upload your source file package (incl. xml and images)?

doesn't have to be complete, but enough to work with...

**moagrius** · 12-10-2010, 03:28 PM
