Unity 漫游相机脚本

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
032	public enum   RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
033	public   RotationAxes axes = RotationAxes.MouseXAndY;
034
035	public float   sensitivityX = 15F;
036	public float   sensitivityY = 15F;
037
038	public float minimumX = -360F;
039	public float maximumX = 360F;
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;
049
050	Quaternion originalRotation;
051
052	void Update ()
053	{//Unity3D教程手册：www.unitymanual.com
054
055	CharacterController controller = gameObject.GetComponent<CharacterController>();
056	if (Input.GetMouseButton(1) && axes == RotationAxes.MouseXAndY)
057	{
058	// Read the mouse input axis
059	rotationX += Input.GetAxis("Mouse X") * sensitivityX;
060	rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
061
062	rotationX = ClampAngle(rotationX, minimumX, maximumX);
063	rotationY = ClampAngle(rotationY, minimumY, maximumY);
064
065	Quaternion xQuaternion = Quaternion.AngleAxis(rotationX, Vector3.up);
066	Quaternion yQuaternion = Quaternion.AngleAxis(rotationY, Vector3.left);
067
068	transform.localRotation = originalRotation * xQuaternion * yQuaternion;
069	}
070	else if (Input.GetMouseButton(1) && axes == RotationAxes.MouseX)
071	{
072	rotationX += Input.GetAxis("Mouse X") * sensitivityX;
073	rotationX = ClampAngle(rotationX, minimumX, maximumX);
074
075	Quaternion xQuaternion = Quaternion.AngleAxis(rotationX, Vector3.up);
076	transform.localRotation = originalRotation * xQuaternion;
077	}
078	//Unity3D教程手册：www.unitymanual.com
079	Vector3   moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
080	moveDirection = transform.TransformDirection(moveDirection);
081	moveDirection *= speed;
082	controller.Move(moveDirection * Time.deltaTime);
083	}
084	void Start ()
085	{
086	// Make the rigid body not change rotation
087	if (rigidbody)
088	rigidbody.freezeRotation = true;
089	originalRotation = transform.localRotation;
090	}
091	public static float ClampAngle   (float angle, float min, float max)
092	{
093	if (angle < -360F)
094	angle += 360F;
095	if (angle > 360F)
096	angle -= 360F;
097	return Mathf.Clamp (angle, min, max);
098	}
099	}
