【Unity笔记】摄像机跟随目标角色

public class CameraFollow : MonoBehaviour
{
    public Transform target;            // The position that that camera will be following.
    public float smoothing = 5f;        // The speed with which the camera will be following.
    Vector3 offset;                     // The initial offset from the target.
 
    void Start ()
    {
        // Calculate the initial offset.
        offset = transform.position - target.position;
    }
 
    void FixedUpdate ()
    {
        // Create a postion the camera is aiming for based on the offset from the target.
        Vector3 targetCamPos = target.position + offset;
 
        // Smoothly interpolate between the camera's current position and it's target position.
        transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
    }
