Hi,

I’m very new to AS3 and I had a couple of questions.

1. Is there a way to attach an object of the :Object() class to a MovieClip? In AS2, if you used the attachMovie method, you could attach an init Object to a movie clip and I’m wondering if there’s any way to store an object of the Object class inside of a MovieClip so that I can store data associated with that movie clip, inside of the movie clip itself. The only way I can figure out to do anything similar to this right now is to create an array of all the objects and give each of the movieclips an indexable name that I can associate with the items of the array, so the objects aren’t actually contained in the movie clip itself, but in a seperate array. You cannot use the addChild method to a non-display object and the Object class is not a display object so I cannot attach it to a movieclip using this method.

2. How do you get detailed error messages in the Flash IDE? Right now, everytime I get an error, it will just say something like “A property is undefined” or “cannot access properties of a null object reference” but it does not give me any line numbers to let me know what line of code the program is having trouble with. How do I get line numbers or anything more detailed in the error messages?

If anyone could please provide me some help with either of these issues, I’d be very thankful.

Thanks,

TheInternet.
