这里的镜头主要是从人物的背后尾随的。

首先新建一个C#脚本，命名为MyFollow，然后把下面代码粘贴进去。保存：

using UnityEngine;
using System.Collections;

public class MyFollow : MonoBehaviour
{
	public float distanceAway = 5;			// distance from the back of the craft
	public float distanceUp = 2;			// distance above the craft
	public float smooth = 3;				// how smooth the camera movement is
	
	private GameObject hovercraft;		// to store the hovercraft
	private Vector3 targetPosition;		// the position the camera is trying to be in
	
	Transform follow;
	
	void Start(){
		follow = GameObject.FindWithTag ("Player").transform;	
	}
	
	void LateUpdate ()
	{
		// setting the target position to be the correct offset from the hovercraft
		targetPosition = follow.position + Vector3.up * distanceUp - follow.forward * distanceAway;
		
		// making a smooth transition between it's current position and the position it wants to be in
		transform.position = Vector3.Lerp(transform.position, targetPosition, Time.deltaTime * smooth);
		
		// make sure the camera is looking the right way!
		transform.LookAt(follow);
	}
}

接着把上面的这个脚本挂载到摄像机上。

最后把你想尾随的人物的tag设为Player。

执行游戏后，摄像机就能够从人物背后尾随人物了。
