Buttons

[Martin]

I want to make a button animation that, when hovered over it fades towards black, and then when not hovered over, it fades back towards gray. So I figured that the best way to do this without flickering would be to use this._alpha, and increase or decrease that value depending on where the mouse was. This didn't work for some reason. Anyone know why, and how I can fix it/do this a different way? Thanks.
