What is the best way to do an animation through existing sprite sheet Atlas

Hello,

I was wondering, what is the fastest / easiest way to do an animation using an existing sprite sheet and to switch easily from one to another sheet, just by setting-up the dimension of each sprite + offsett + number of row.

Example of existing Atlas :

As far as i understood, Sprite Manager is not able to do that kind of thing ( At least, after checking the video tutorial on their website ) but can only manage it using separate images. From that, SM build his own Atlas.

I’m open to any kind of plugin.

Thank you very much

Florent

Maybe I don’t understand your problem, but this is not what you need? http://wiki.unity3d.com/index.php/Animating_Tiled_texture
