You need to rename the class in the file to LookAtCameraYonly.

Hi ,I think I did it.

using UnityEngine;
using System.Collections;

public class LookAtCameraYonly : MonoBehaviour
{
public Camera cameraToLookAt;

void Update()
{
Vector3 v = cameraToLookAt.transform.position - transform.position;
v.x = v.z = 0.0f;
transform.LookAt(cameraToLookAt.transform.position - v);
}
}

Is the file named LookAtCameraYonly?

C# needs file name and class name to match.

OU, It works now, my mistake here.

thankyou very much for replying,

but I still have another question.

If I have 3 cameras in a scene I already made swich between them in a empty GameObject , then how can I make a object always look at camera, even the camera is switched between these 3 cameras?

thanks again.
