小弟是美工，刚接触编脚本没几天，今天试着修改了一下unity3d 自带的视角控制脚本MouseLook.cs

其中第45行是小弟添加的，实现了绕角色旋转的功能，但是碰到一个问题，就是视角的角度和绕角色旋转的移动速度不一致。而数学对于我来说实在是无力。

求教在这个脚本中视角角度和旋转移动速度的关系。

附上脚本

using UnityEngine;

using System.Collections;

/// MouseLook rotates the transform based on the mouse delta.

/// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character:

/// - Create a capsule.

/// - Add the MouseLook script to the capsule.

/// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)

/// - Add FPSInputController script to the capsule

/// -> A CharacterMotor and a CharacterController component will be automatically added.

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.

/// - Add a MouseLook script to the camera.

/// -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
