This is probably very easy to do, but I can't find a way of doing it. I wanted to change the alpha of a sprite when my cursor in over it, just like Jquery's hover() function. I tried doing something like this: image.events.onInputOver.add(listener, this); function listener (image) { image.alpha = 0.5; } And it changed the alpha, but it didn't go back to normal when my cursor went outside the sprite. The effect I wanted was: Mouse over? Change alpha to 0.5 Mouse off? Alpha back to normal How can I do this effect? I really appreciate any help you can provide!
