1.修改unity3d的Mouse Look相机脚本：按住右键控制前进方向，方向键改变位置
2.给场景相机添加系统自带的fpswalker脚本
3.指定fpswalker里transform指定场景相机
PS：Mouse Look.cs修改部分：
|
|
|
001 |
void Update () |
|
002 |
{ |
|
003 |
if (Input.GetMouseButton(1) && axes == RotationAxes.MouseXAndY) |
|
004 |
{ |
|
005 |
// Read the mouse input axis |
|
006 |
rotationX += Input.GetAxis("Mouse X") * sensitivityX; |
|
007 |
rotationY += Input.GetAxis("Mouse Y") * sensitivityY; |
|
008 |
|
|
009 |
rotationX = ClampAngle(rotationX, minimumX, maximumX); |
|
010 |
rotationY = ClampAngle(rotationY, minimumY, maximumY); |
|
011 |
|
|
012 |
Quaternion xQuaternion = Quaternion.AngleAxis(rotationX, Vector3.up); |
|
013 |
Quaternion yQuaternion = Quaternion.AngleAxis(rotationY, Vector3.left); |
|
014 |
|
|
015 |
transform.localRotation = originalRotation * xQuaternion * yQuaternion; |
|
016 |
} |
|
017 |
else if (Input.GetMouseButton(1) && axes == RotationAxes.MouseX) |
|
018 |
{ |
|
019 |
rotationX += Input.GetAxis("Mouse X") * sensitivityX; |
|
020 |
rotationX = ClampAngle(rotationX, minimumX, maximumX); |
|
021 |
|
|
022 |
Quaternion xQuaternion = Quaternion.AngleAxis(rotationX, Vector3.up); |
|
023 |
transform.localRotation = originalRotation * xQuaternion; |
|
024 |
} |
|
025 |
} |
|
026 |
|
|
027 |
当然也可以，直接用以下脚本： |
|
028 |
using UnityEngine; |
|
029 |
using System.Collections; |
|
030 |
public class MouseLook : MonoBehaviour { |
|
031 |

|
033 |
public RotationAxes axes = RotationAxes.MouseXAndY; |
|
034 |
|
|
035 |
public float sensitivityX = 15F; |
|
036 |
public float sensitivityY = 15F; |
|
037 |
|
|
038 |
public float minimumX = -360F; |
|
039 |

|
040 |
|
|
041 |
public float minimumY = -60F; |
|
042 |
public float maximumY = 60F; |
|
043 |
|
|
044 |
float moveSensitivity = 1.0f; |
|
045 |
public float speed = 6.0f; |
|
046 |
|
|
047 |
float rotationX = 0F; |
|
048 |
float rotationY = 0F; |
|
