Following camera Unity

Question

I want that camera follow the player. For this I use player's(in target) transform and change camera's transform.

public class CameraScript : MonoBehaviour
{
    public Transform target;
    private Vector3 delta;

    void Start()
    {
        delta = Camera.main.transform.position - target.position;
    }

    void Update()
    {
        Camera.main.transform.position = target.position + delta;
    }
}

This method works, but it's a better solution?

Answer 1

It comes down to what "better" means, but generally doing a little interpolation to smooth out the camera's motion looks better (although for VR it's not so simple)

Something like this should work:

public class CameraScript : MonoBehaviour
{
    public Transform target;
    public float lerpSpeed;
    private Vector3 delta;

    void Start()
    {
        delta = Camera.main.transform.position - target.position;
    }

    void Update()
    {
        Camera.main.transform.position = Vector3.Lerp(Camera.main.transform.position, target.position + delta, lerpSpeed * Time.deltaTime);
    }
}
