Hello,

I am having issues with an error using the TransitionManager, using Flash CS3, ActionScript 2.0 …here’s my error:

The class or interface ‘TransitionManager’ could not be loaded.

The error is refering to:

var popUpTransitionManager:TransitionManager;

Yes, I have the import statement in my FLA.

I’m using the training book, which comes with complete files. When I play the unaltered, complete files, I don’t get the error. However, when I just look at the .as file and do a syntax check, it yells the error at me.

This is the only solid info I found on the matter… the blog post doesn’t exactly help, but the second comment addresses AS2. Here’s the link:

Anyone got any ideas on how to fix this OTHER than having to use a tween class? (unless you think the tween class is the BEST solution.)

Thanks, as always,

/\*After thought: Why is this happeneing? TransitionManager seems like it’s an important part of ActionScript. I’m still learning about this stuff, and I planned on using Transitions in a HUGE upcoming project. Sorry. End rant \*/
