Re: FLASH: Whats THE MACS PROBLEM???

[John Croteau]

Hi Steve,


I think you are lucky that Byron posted the error to the list.

The errors that visitors get in going to Berny have not been limited to

Mac guys. I have received them using Windows. Maybe Macs are more

susceptible to the problem or they are just more vocal :-). Though I

also mentioned it before (quite some time ago).

Yes, it does. I think it points right at the problem:


var Navigu = InternetExplorer ? MyMovie : document.MyMovie;   

   Navigu.GotoFrame(1);

var Anim = InternetExplorer ? MyAnimation : document.MyAnimation;

   Anim.GotoFrame(20);

   Anim.Play();


The problem (I believe) is that you are calling something that may not

exist yet. It usually will be there when called but not always.

In your init() function you are making calls to both of your Flash

movies. From the error I assume init() is called from MyAnimation

(anim.swf). Even though you are calling frame one in MyMovie (lab.swf)

there is no guarantee that even though it appears first on the page that

it will load first. Just like gifs and jpegs, swf files are not

necessarilly loaded sequentially on a web page.


The solution is to create a pre-init function that will load init() only

after confirming that lab.swf has loaded to frame 1. Also note that

since you are calling frame 20 in anim.swf then you should not call

init() from that movie until frame 20 is loaded.


A second solution would be to call init() from an onLoad but this is

less desirable because both swf files would have to be fully loaded

before init() would be called.
