Model floats in the air when I jump.

So as my model is chasing me, it slowly starts to inch its way up into the air. And if I jump, and it’s still following me it will float in the air. Here’s my script.

var Distance;

var Target : Transform;

var lookAtDistance = 25.0;

var chaseRange = 15.0;

var attackRange = 1.5;

var moveSpeed = 5.0;

var Damping = 6.0;

var attackRepeatTime = 1;

var runanimation = 15;



var TheDammage = 40;



private var attackTime : float;



var controller : CharacterController;

var gravity : float = 20.0;

private var MoveDirection : Vector3 = Vector3.zero;



function Start ()

{

	attackTime = Time.time;

}



function Update ()

{

	Distance = Vector3.Distance(Target.position, transform.position);

	

	if (Distance < lookAtDistance)

	{

		lookAt();

	}

	

	if (Distance > lookAtDistance)

	{

		renderer.material.color = Color.green;

	}

	

	if (Distance < attackRange)

	{

		attack();

	}

	else if (Distance < chaseRange)

	{

		chase ();

		animation.Play("run");

	}

}



function lookAt ()

{

	renderer.material.color = Color.yellow;

	var rotation = Quaternion.LookRotation(Target.position - transform.position);

	transform.rotation = Quaternion.Slerp(transform.rotation, rotation,Time.deltaTime * Damping);
}




function chase ()

{

	renderer.material.color = Color.red;

	

	moveDirection = transform.forward;

	moveDirection *= moveSpeed;

	

	moveDirection.y -= gravity * Time.deltaTime;

	controller.Move(moveDirection * Time.deltaTime);

}



function attack ()

{

	if (Time.time > attackTime)

	{

		Target.SendMessage("ApplyDammage", TheDammage);

		Debug.Log("The Enemy Has Attacked");

		attackTime = Time.time + attackRepeatTime;

	}

}



function ApplyDammage ()

{

    chaseRange += 30;
    moveSpeed += 2;
    lookAtDistance += 40;

}

Change your lookAt() function:

function lookAt ()
{
    renderer.material.color = Color.yellow;
    var look = Target.position - transform.position;
    var look.y = 0.0;
    var rotation = Quaternion.LookRotation(look);
    transform.rotation = Quaternion.Slerp(transform.rotation, rotation,Time.deltaTime * Damping);
}
