Transform.Rotate(Vector3,Space);

旋转：函数方法

Transform trans;

1. //Rotate沿着z轴每秒旋转speed度(自身旋转)

        trans.Rotate(Vector3.forward * Time.deltaTime * speed);

   2.//围绕旋转RotateAround();

        trans.RotateAround(Vector3(x,y,z),target.up,Time.deltaTime * speed);

//参数1：围绕的点，参数2：绕哪个轴旋转，参数3：旋转速度

    3.//LookAt()看向某物体（z轴指向某物体）;

    trans.LootAt(target);
