Hey,
I'm pretty new to away3d, actionscript and programming in general (I'm
a 3d artist) so please keep that in mind. I want to make a simple HUD
on top of a away3d scene but i cant get the event listeners to work on
2d shapes. The hud button should control the camera position as u can
see in the code below. For the button i used a simple circle shape and
added an event listener to it but unfortunately my method doesn't
work.
How can i get hud buttons to work (make clickable) in away3d?
