【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);
}
