2D Game and Camera Folow script. How to follow the player?

Hi, I've create this script attached to the camera to follow my character.

Code (csharp):

1.  
2. public class CameraFollow : MonoBehaviour {
3.  
4.     private Transform player;       // Reference to the player's transform.
5.  
6.     void Awake ()
7.     {
8.         // Setting up the reference.
9.         player = GameObject.FindGameObjectWithTag("Player").transform;
10.     }
11.    
12.    
13.     void Update ()
14.     {
15.         transform.position = new Vector3 (player.position.x + 2, player.position.y, -10);
16.     }
17. }
18.  

As you can see, the camera is 2 points ahead of my character, but what i want, is that when my players moves to the left, the camera moves to points in the opposite side.

how can i do that??

Thanks in advance.

 

I am not sure exactly what you are after, but perhaps my little camera script will be helpful to you:

Code (csharp):

1.  
2. using UnityEngine;
3.  
4. public class CameraFollow2D : MonoBehaviour {
5.    
6.     // Transform of target object, defaults to player
7.     public Transform target;
8.     // Time in seconds for smoothing
9.     public float smoothTime = 0.5f;
10.     // Distance from target
11.     public float distance = 5.0f;
12.    
13.     // Local copy of transform to reduce component lookups
14.     Transform _transform;
15.     // Velocity of camera smoothing
16.     Vector3 _smoothVelocity;
17.    
18.     void Start() {
19.         _transform = transform;
20.        
21.         if (target == null) {
22.             // Point at player by default
23.             GameObject player = GameObject.FindWithTag("Player");
24.             if (player != null)
25.                 target = player.transform;
26.         }
27.     }
28.    
29.     void Update() {
30.         if (target != null) {
31.             // Point camera towards target
32.             Vector3 targetPosition = target.position;
33.             targetPosition.z -= distance;
34.            
35.             _transform.position = Vector3.SmoothDamp(_transform.position, targetPosition, ref _smoothVelocity, smoothTime);
36.         }
37.     }
38. }
39.  

If not, just ignore it hehe

 

Thank you very much. That's was really helpfull !!!
