unity实现摄像机绕某点旋转⼀周在Update函数中执⾏：
if (turnAround)
{
playerCamera.RotateAround(transform.localPosition, transform.up, Time.deltaTime * rotateSpeed);
degree += Time.deltaTime * rotateSpeed;
if (degree >= 360)
{
turnAround = fal;
degree = 0;
}
}
补充：unity 摄像机围绕某个物体进⾏旋转放⼤缩⼩
脚本通过以⼀个物体为中⼼点
来控制摄像机围绕物体旋转缩放，脚本挂在摄像机上即可，target是需要观看的物体
public Transform Camera2;
public GameObject target;
private float dis;
public float xSpeed = 200, ySpeed = 200, mSpeed = 10; //移动速度
revolve
public float yMinLimit = -50, yMaxLimit = 50; //摄像机的Y轴移动最⼩最⼤限制
public float distance = 7, minDistance = 2, maxDistance = 30; //摄像机与⽬标物体的距离
public bool needDamping = true; //阻尼默认开启
rain cats and dogsfloat damping = 5.0f; //默认阻尼为5.0F

}
distance -= Input.GetAxis("Mou ScrollWheel") * mSpeed;
