2D camera follow horizantal only?

so I’m fairly new to scripting and I got this script online
var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;
var lockRotation : boolean;

function Update () {
	target = GameObject.FindGameObjectWithTag("Player").transform;
	var wantedPosition = target.TransformPoint(0, height, -distance);
	transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

	if (smoothRotation) {
		var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
		transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
	}

	else transform.LookAt (target, target.up);

	if(lockRotation) 
		transform.localRotation = Quaternion.EulerAngles(0,0,0);
}

this makes the camera follow the player smoothly and I’ve been playing around with it for a while but I can’t figure out how to add a variable that would make the camera only follow the target on the x axis. How would I do this? thank you.

Easy… you want your camera to follow an object, but you want to control the xyz elements of the follow independently, just write a camera.position = Vector3(x = 2units (constant eyelevel), y = leading object.y (smooth with mathf. dampen function), z same as y)

or if you want it to move on x and other stuff say the same, control the same but visa versa
