Re: [flexcoders] actionscript class in Flex project
Your suggestion worked fine, thanks.
I double checked my version and there are no errors.
Here is my version which has AnimatedBall , an extention of sprite being
used as a child of the Application, but has no errors, with the source
code, if anyone's interested
http://www.geotonics.com/examples/Animation/Animation.html.

can’t be children of Applications. The rules in Flex are:
Navigator children must be Containers
Container children must be IUIComponents
UIComponent children can be anything.
There are also component lifecycle behaviors you have to know about to
be a good flex component, such as which methods to override when, and
that you are sized by your parent.
When you compile AnimatedBall as its own project, you get a small swf
with the Ball as the main class at a default size of 500x375.
When you make it a child of Application, you should normally get an
error, but if you subclass UIComponent you’ll get further, but you’ll
also need to specify a size for it.
So, change “extends Sprite” to “extends UIComponent” and size the tag
something like com:AnimatedBall width=”100%” height=”100%”

I made a mistake in the last post (I didn't intend to call init() in the
application tag)
corrected version :
I have an action script file of an animated ball. 20 is added to x on
every frame. If I create an actionscript project and run it, it works
fine. Now how do I include this class in a flex project ?
If I create a mxml file like this I thought it would have the ball in
it. It runs, but there is not ball, no errors no nothing. The code for
the ball is below

I'm surprised there is no error (I didn't try it though). Sprites can't
be children of Applications. The rules in Flex are:
Navigator children must be Containers
Container children must be IUIComponents
UIComponent children can be anything.
There are also component lifecycle behaviors you have to know about to
