unity - Use an object's x position to seek within an animation

I have an animation clip I want to play, using the object's x position to control which frame of the animation is displayed. ie.

• When the object is at x = -2, the animation should show its initial frame.


• As the object moves rightward (increasing x) the animation should play forward.


• When the object is at x = 6, the animation should show its final frame.


• As the object moves leftward (decreasing x) between these values, the animation should play in reverse.

I thinks this is a form of clamping where I want to map x values into key frames of the animation.

Below just a simple code to run animation:

void Update () {
    if (isPositionChanging)
    {
        if(transform.position.x > xPos){
            if(incrementOrDecrement <=12) {
            incrementOrDecrement ++;
            AnimationPlayOnPositionValue(1, incrementOrDecrement);
            }
        }

        else {
            if (incrementOrDecrement >= 0)
            {
            incrementOrDecrement--;
            AnimationPlayOnPositionValue(1, incrementOrDecrement);
            }
        }

    }
}


void AnimationPlayOnPositionValue(float speed,float timeToUpdate) {
    animatedObject["MachineAnimationComplete"].speed = speed;
    animatedObject["MachineAnimationComplete"].time = timeToUpdate;
    animatedObject.Play();

}
