Rewind/Play animations on demand.

Hi, I am trying to get an animation to play when the spacebar is pressed then when it is pressed again I want the animation to rewind from where it is. Then if the animation had finished playing I want it rewind back to the beginning. I have written a script but when the animation has finished playing and you press the spacebar the animation jumps to the beginning instead of rewinding it. Please help! Here's my script.

var keysToggle=0; var keyAnim=0.0;

function Update () { if (Input.GetKeyDown(KeyCode.Space)){ keyAnim=(animation["KeysAnim"].time); if (keysToggle > 0) { if (animation["KeysAnim"].time < 0.1) { animation["KeysAnim"].time = 0; animation["KeysAnim"].speed = 1.0; animation.Play ("KeysAnim"); keysToggle=0; } else { animation.Stop ("KeysAnim"); animation["KeysAnim"].time = keyAnim; animation["KeysAnim"].speed = 1.0; animation.Play ("KeysAnim"); keysToggle=0; } } else { if (animation["KeysAnim"].time < 1) { animation.Stop ("KeysAnim"); animation["KeysAnim"].time = keyAnim; animation["KeysAnim"].speed = -1.0; animation.Play ("KeysAnim"); keysToggle=1; } else { animation["KeysAnim"].time = 1; animation["KeysAnim"].speed = -1; animation.Play ("KeysAnim"); keysToggle=1; } } } }
