【Unity】实现相机视角跟随

在U3D项目中实现相机永远跟随玩家，是玩家模型保持在镜头最中间

	private Transform player;
	//玩家和相机的差
	private Vector3 offset; 
	//相机移动速度
	private float speed = 3;
 
	// Start is called before the first frame update
	void Start() {
		player = GameObject.FindGameObjectWithTag("Player").transform;
		offset = transform.position - player.position;
	}
 
	// 更新相机位置
	void LateUpdate() {
		//世界坐标转化为局部坐标
		Vector3 targetPosition = player.position + player.TransformDirection(offset);
		//移动相机
		transform.position = Vector3.Lerp(transform.position, targetPosition, speed * Time.deltaTime);
		//相机看向玩家的方向
		transform.LookAt(player.position);
}
