Unity does not have a method to goto a specific frame per say. But you can move to a specific time interval of an animation using Gameobject.animation["name"].time – Legacy Animation
So in short, you can actually goto a specific frame by finding the time of the animation at that particular frame. e.g. If the animation speed (visible in the animation window) is 24 fps: It means 24 frames are rendered in 1 sec.
The first frame will be at 1/24 * 1. The second will be at 1/24 * 2. and so on.
So this snippet will do the trick:
gameobjectname.animation.Play ("Take 001"); gameobjectname.animation.Stop (); gameobjectname.animation["Take 001"].speed = 0; //to make the animation pause gameobjectname.animation["Take 001"].enabled = true; gameobjectname.animation["Take 001"].time = (1f/24f)*frameNumber;
