Speed control camera movement

void Update()
{
   float h=Input.GetAxis("Horizontal")*speed*Time.deltaTime;
   float v=Input.GetAxis("Vertical")*speed*Time.deltaTime;
   transform.Translate(h,0,v);//或者可以分开写
 
 //transform.Translate(Vector3.right*h);
 //transform.Translate(Vector3.forward*v);

}

speed is the step size, the step size is multiplied by the time distance of each frame is

deltaTime is this frame to the next rendering pass the time.
