Re: [Flashcoders] Loading images at the same time, bugs in Flash AS3
I would love to see what's going on, as it sounds crazy; yet, your site isn't coming up for me.

So these three sequences of images start loading at the same time, and placing the images as elements in the arrays in order to be more easily handled (to my point of view). Naturally the thumbnails finish loading first. If I click on a thumbnail whose corresponding image is not yet loaded, It starts loading it.

There are lots of other things I could have done better for example, placing many of the elements inside of a movieclip, for example a bar which would contain all the elements of the thumbnail mechanismus ( containers, masks, buttons). I've tried that but it was maybe too late, for it was difficult cause I had many references to those elements with in the code. There's no document class, and 80% of the code is written in one frame.

Another problem is that the browser's window simply closes itself by clicking on an item in the menu, that happend in Safari and Firefox. 3.

Re: [Flashcoders] Loading images at the same time, bugs in Flash AS3
Without looking through your code: * For alignment of the thumbnail container, you could be waiting until after everything has loaded inside before asking it to change it's y position. * For the thumbs not loading properly, that could be caused by your load order... Your downloads are racing each other. Things need to be loaded in sequence for stability; yet, you are, if I am not mistaken, downloading everything at once in a loop, not waiting until one thing downloads until you go to the next; yet, in your display, you are making it wait. Flash lets you send multiple requests at once and does not automatically que your requests, in the sense that only one can happen at a time; therefore, if something needs to load in sequence, you need to put safeguards in your code to ensure that things get loaded in order of priority.

Re: [Flashcoders] Loading images at the same time, bugs in Flash AS3
My guess is that if it's iterating through a loop to load, I would imagine that the loader objects are being lost in the loop by getting de-referenced and are getting garbage collected. If this is what's happening, you would probably have to put your loader objects in a stack or array so they don't get de-referenced, and then do some housekeeping to remove them once they have been loaded. jord Anthony Pace wrote: Without looking through your code: * For alignment of the thumbnail container, you could be waiting until after everything has loaded inside before asking it to change it's y position. * For the thumbs not loading properly, that could be caused by your load order...
