Player的跟踪狂 -- Camera

P.S.很多游戏里的Player都会设置的被跟踪，是人性的扭曲，还是XXX,正在解密。

第三人称视角

1. camera紧跟player背后（角度随player改变）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FollowTarget : MonoBehaviour {

    private Transform player;
    private Vector3 offset;//偏移值
    private float smoothing = 3.0f;//平滑度

	// Use this for initialization
	void Start () {
        player = GameObject.FindGameObjectWithTag("Player").transform;
        offset = transform.position - player.position;
	}
	
	// Update is called once per frame
	void LateUpdate () {
        Vector3 targetPosition = player.position + player.TransformDirection(offset);//局部坐标，跟随背后
        transform.position = Vector3.Lerp(transform.position, targetPosition, Time.deltaTime * smoothing);
        transform.LookAt(player);
	}
}

效果如下：（一直保持这个视角）

2. camera保持一个角度做俯视（像被上帝注视，颤抖吧player!）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FollowTarget : MonoBehaviour {

    private Transform player;
    private Vector3 offset;
    private float smoothing = 3.0f;//平滑度

	// Use this for initialization
	void Start () {
        player = GameObject.FindGameObjectWithTag("Player").transform;
        offset = transform.position - player.position;
	}
	
	// Update is called once per frame
	void LateUpdate () {
        Vector3 targetPosition = player.position + offset;//世界坐标，上帝视角
        transform.position = Vector3.Lerp(transform.position, targetPosition, Time.deltaTime * smoothing);
        transform.LookAt(player);
	}
}

效果如下：（可以看到身前）

两个跟踪方式只有一行代码的不同，但是游戏体验效果差很多，自己实现体现被跟踪的乐趣吧。
