Need camera to follow player, but not the player's rotation.

Question

So I'm building a simple platform game (think something like Mario, prince of persia, take your pick etc). The camera follows the player through the level, simply by being a child of the player's object.

The problem is that I made my character turn back and forth. I.E. if you are facing right and hit the left key, the character object is turned 180 degrees. That works great, except that the camera (being a child of the the Player) also turns 180 degrees!

Is there a way I can lock the camera's rotation, or just have it follow the player's movement on the X and Y axis, without taking the player's rotation?

I can think of some bizarre solutions that might work, but I'm betting there is a cleaner, more efficient solution then for example un-parenting the player from the camera before a flip, and then re-parenting the player to the camera afterward.

Thanks for all your help, having a blast with Unity :)

I did something similar said by unfoundfate. The code that is attached to the camera goes like this:-

 var Stone : GameObject;
 
 function Update()
 {
     transform.position.y= Stone.transform.position.y; 
 // in this case I only needed to care about the height
 }

this was attached to the camera, now drag and drop the gameobject from Hierarchy(or prefab) to the Stone in Inspector panel. This worked!

This worked. Thanks allot... but I noticed the camera is droping to the bottom of the character (my character feet starts from 20.08 and my camera is set to 42 to look in the middle of it). is there any simple add to your code that will freeze the droop of the camera?

Just put this script on your Main Camera. Set the cameraOrientationVector to how far from your character you want it to be. And tilt the camera in scene view for the angle.

  using UnityEngine;
         using System.Collections;
         
         public class CameraScript : MonoBehaviour 
         {
             Transform playerTransform;
             
             Vector3 cameraOrientationVector = new Vector3 (0, 15, -10f);
             
 
 void Start () 
     {
         
         
         
         playerTransform = GameObject.Find ("Player").transform;
     }
             
         void LateUpdate () 
             {
                 
                 transform.position = playerTransform.position + cameraOrientationVector;
                 
             }
         }

     public Camera PlayerCamera;
     public GameObject Spawn;
 
 void Update() {
 Vector3 CamPos = new Vector3(player.transform.position.x,player.transform.position.y,0);
 camera.transform.position = CamPos;
 }

this code will "parent" the camera to the players x and y position, but allows you to control the Z pos and rotation yourself.

Sorry to be a complete noob.

I've Un-parented the camera from the player, then created a new Js script and pasted the code Navigatron gave above then dropped the script onto the camera.

However, I get the following error. "Assets/Standard Assets/Character Controllers/Sources/Scripts/transform.js(5,16): BCE0018: The name 'Float' does not denote a valid type ('not found')."

And no target slot is created.

I just had great luck by implementing the following code in C#, follows player transform but not rotation. Note it requires the object to be followed to be tagged as "Player", still new to Unity and not sure how to reference directly:

public class CameraMovement : MonoBehaviour { private Transform player; private Vector3 relCameraPos;

 void Awake()
 {
     player = GameObject.FindGameObjectWithTag("Player").transform;
     relCameraPos = player.position-transform.position;
 }
 void Update()
 {
     transform.position = player.position-relCameraPos;
 }

}
