How to use FadeImageAnimation?

Hi,

I've been trying to get an image to fade in my game, but so far it doesn't work:

FadeImageAnimation fia = new FadeImageAnimation(IconManager.getInstance().getIcon(piece),loc.x,loc.y,100f,-.1f,0f);
fia.addAnimationObserver(this);
fia.setRenderOrder(2);
addAnimation(fia);

The getIcon() just returns a Mirage object. I know that part works at least, because I can get a ScaleAnimation to work just fine, with similar code.

Is there some special trick to getting fades to work? Thanks.

Re: How to use FadeImageAnimation?

What exactly is the problem? Is it not fading at all or just disappears suddenly? If it's just disappearing, try lowering the step value (By a lot!) to get a slower fade-out.

Someone has put together a demo of all the different Animations, check it out with CVS using:

cvs -d :pserver:anonymous@skovran.com:/usr/local/cvsroot co mediatest

Re: How to use FadeImageAnimation?

Thanks, that demo code helped a lot. I was just using really wrong values for the alpha and step. I changed it to

new FadeImageAnimation(IconManager.getInstance().getIcon(piece),loc.x,loc.y,1f,-.002f,0f);

...and it works fine.
