标题: 【代码请教】关于相机视角滑动如何产生缓慢减速至零的...
FPS里的相机自带的一个script 叫Mouse Look,我把它改了改，使其相机视角依旧随着鼠标滑动，但前提是按下鼠标左键：
using UnityEngine;
using System.Collections;
[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook0 : MonoBehaviour {
public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
public RotationAxes axes = RotationAxes.MouseXAndY;
public float sensitivityX = 15F;
public float sensitivityY = 15F;
public float minimumX = -360F;
public float maximumX = 360F;
public float minimumY = -60F;
public float maximumY = 60F;
float rotationX = 0F;
float rotationY = 0F;

public float mousex;
public float mousey;
public float lastmousex=0F;
public float lastmousey=0F;

Quaternion originalRotation;
void Update ()
{
  if (Input.GetMouseButton(0))
  {
  if (axes == RotationAxes.MouseXAndY)
  {
// Read the mouse input axis
mousex=Input.GetAxis("Mouse X");
mousey=Input.GetAxis("Mouse Y");
rotationX += (mousex-lastmousex)* sensitivityX;
rotationY += (mousey-lastmousey) * sensitivityY;
rotationX = ClampAngle (rotationX, minimumX, maximumX);
rotationY = ClampAngle (rotationY, minimumY, maximumY);

Quaternion xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
Quaternion yQuaternion = Quaternion.AngleAxis (rotationY, Vector3.left);

transform.localRotation = originalRotation * xQuaternion * yQuaternion;
  }
  else if (axes == RotationAxes.MouseX)
  {
mousex=Input.GetAxis("Mouse X");
rotationX += (mousex-lastmousex)* sensitivityX;
rotationX = ClampAngle (rotationX, minimumX, maximumX);
Quaternion xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
transform.localRotation = originalRotation * xQuaternion;
  }
  else
  {
mousey=Input.GetAxis("Mouse Y");
rotationY += (mousey-lastmousey) * sensitivityY;
rotationY = ClampAngle (rotationY, minimumY, maximumY);
Quaternion yQuaternion = Quaternion.AngleAxis (rotationY, Vector3.left);
transform.localRotation = originalRotation * yQuaternion;
  }
  }
}

void Start ()
{
  // Make the rigid body not change rotation
  if (rigidbody)
rigidbody.freezeRotation = true;
  originalRotation = transform.localRotation;
}

public static float ClampAngle (float angle, float min, float max)
{
  if (angle < -360F)
angle += 360F;
  if (angle > 360F)
angle -= 360F;
  return Mathf.Clamp (angle, min, max);
}
}

想请教的是，如果想要给相机视角加上缓动的效果~
即，相机的视角随着鼠标不是立即停止或启动，而是每当鼠标开始移动或停止，视角都有个相应的加速或减速的过程，
该如何实现？提供个思路亦可。XD~

有点类似滑动的意思，求指点
