I'm having some trouble with an animation. The normalized time never reaches 1.0, and the animation constantly repeats, even though it's wrap mode is WrapMode.Once.

I've posted a video that explains the issue in more detail : http://www.youtube.com/watch?v=I4WQdjMWo5Q&feature=youtu.be

Here's part of the script that plays the animation:

public void Crouching(){

    // Do the crouch
    if (Input.GetButton("Crouch")){


       // TODO: HACK!!!
       if (animation["Crouching_m"].normalizedTime < 0.8f){
         animation["Crouching_m"].speed = 1;
         animation.CrossFade("Crouching_m");

       }
       else{
         //animation.Stop("Crouching_m");
         animation["Crouching_m"].speed = 0f;
         animation.CrossFade("Crouching_m");
       } 

    }
    else{
       animation["Crouching_m"].speed = -1;
       if (animation["Crouching_m"].normalizedTime > 0.0f){
         animation.CrossFade("Crouching_m");
       }
    }

    // Switch back if the animation is finished
    if (animation["Crouching_m"].speed < 0 && 
       animation["Crouching_m"].time <= 0){
       SwitchState(EntityState.GROUNDED);
    }

}
