Re: [Flashcoders] using Bitmap for hitArea

2009-06-23 Thread Andrew Sinning
Thanks Leandro.  I took an initial look at this, but got scared off by 
the fact that this is going to make mouseUp/Down/Enter/Leave and click 
detection really complicated, much more complicated than anything I've 
ever had to deal with before.  There will be follow-up questions, but 
first I need to start a new thread.

If I draw a circle using the Graphics and Shape classes, and then add the
shape to a sprite, I can use the sprite for the hitArea of another sprite
and it works just fine.  Everything within the circle is a hit, everything
outside of it is a miss.

However, if I create a sprite containing a Bitmap drawn from this same
circle and try to use this sprite for the hitArea, the entire rectangle
becomes the hit area.  I've played around with different alpha-levels, using
white and black, and using the opaqueBackground setting.  Nothing seems to
work.  Am i missing  something or is this a known limitation?

I'm using AS3 under Flash CS3.

Thanks!
