（有什么问题或不足请多多指教）

【第一人称设计】

unity专业版给我们提供了第一人称控制器，这里我也只是使用官方提供的脚本，在必要地方做了一些些修改

首先将我提供的工程素材下载下来，将主角模型添加进去（可能你的材质需要自己拖进主角里）

在主角上添加图下图必要的组件和脚本：

将我如下图标记处选择Mouse X 这样主角面向会随我们鼠标的在屏幕X方向的移动而旋转

接下来就是主角的视野问题

在模型上按如下图为添加摄像机

微调好摄像机位置后

在Bip01 Spine2上添加Mouse Look C#脚本组件

修改其部分代码：

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.)[AddComponentMenu("Camera-Control/Mouse Look")]public class SpineAngles : 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 rotationY = 0F;    private Vector3 eulerAngle;    void LateUpdate()    {        if (axes == RotationAxes.MouseXAndY)        {            float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;            rotationY = Mathf.Clamp(rotationY, minimumY, maximumY);            transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);        }        else if (axes == RotationAxes.MouseX)        {            transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);        }        else        {            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;            rotationY = Mathf.Clamp(rotationY, minimumY, maximumY);            transform.localEulerAngles = new Vector3(eulerAngle.x, eulerAngle.y, eulerAngle.z + rotationY);        }    }    void Start()    {        // Make the rigid body not change rotation        if (GetComponent<Rigidbody>())            GetComponent<Rigidbody>().freezeRotation = true;        eulerAngle = this.transform.localEulerAngles;    }}

【主角的动画控制】

给主角添加一个自定义名为SoldierAnimationController的C#脚本组件：

SoldierAnimationController.cs

using UnityEngine;using System.Collections;public class SoldierAnimationController : MonoBehaviour {    private CharacterController soldierController;    private Animation soldierAnima;// Use this for initializationvoid Start ()     {    soldierController=this.GetComponent<CharacterController>();        soldierAnima=this.GetComponent<Animation>();}// Update is called once per framevoid Update ()     {        //判断主角是否着地        if (soldierController.isGrounded == false)        {            CrossState("soldierFalling");        }        else        {            float h=Input.GetAxis("Horizontal");            float v = Input.GetAxis("Vertical");            if (Mathf.Abs(h) >= 0.1f || Mathf.Abs(v) >= 0.1f)            {                CrossState("soldierWalk");            }            else            {                CrossState("soldierIdle");            }        }}    void CrossState(string animaName)    {        //缓存0.2秒后，切换动画        soldierAnima.CrossFade(animaName,0.5f);        soldierAnima.Play(animaName);    }}

【给主角添加枪支】

将枪支模型拖动到右手关节上，随右手移动而改变位置，如下图：

效果图如下：

【创建子弹模型】】

在hierachy选项卡想点击Create->3D Object->Quad

将子弹贴图拖动到其中后，将自动生成一个材质

接下来在子弹对象上挂载一个控制其运动的脚本组件

代码如下：

using UnityEngine;using System.Collections;public class BulletManager : MonoBehaviour {    public float bulletSpeed = 800;    private Vector3 startPos;    private Vector3 currentPos;    // Use this for initializationvoid Start ()     {        }// Update is called once per framevoid Update ()     {        //由于子弹的移动速度很快，如果每一帧进行检测碰撞时，将有可能检测不到碰撞物        startPos = this.transform.position;        this.transform.Translate(Vector3.forward*Time.deltaTime*bulletSpeed, Space.Self);        currentPos = this.transform.position;    }}

接下来在枪支口上创建一个空的游戏对象，用于确定子弹实例化时的位置

在其添加一个脚本组件，控制子弹的实例化及接下来的弹痕效果演示

using UnityEngine;using System.Collections;public class InstanceBullet : MonoBehaviour {    public Camera soldierCamera;    public GameObject bulletObj;    //弹痕    public GameObject[] holes;// Use this for initializationvoid Start ()     {        }// Update is called once per framevoid Update ()     {        if (Input.GetMouseButtonDown(0))        {            //GameObject obj = GameObject.Instantiate(bulletObj, this.transform.position, this.transform.rotation) as GameObject;            //Destroy(obj, 10.0f);            Vector3 point = soldierCamera.ScreenToWorldPoint(new Vector3(Screen.width*2/5, Screen.height/2, 0));            //射线碰撞检测            RaycastHit hit;            bool isHit = Physics.Raycast(point, soldierCamera.transform.forward, out hit);            if (isHit)            {                Vector3 hitPos = hit.point;                int index = (int)Random.Range(0.0f, 2.0f);                GameObject hole = holes[index];                GameObject instanceHole = GameObject.Instantiate(hole, hitPos, Quaternion.identity) as GameObject;                //旋转子弹                //hit.norma取得是一个碰撞点所在碰撞面的垂直向量                instanceHole.transform.LookAt(hitPos - hit.normal);                instanceHole.transform.Translate(Vector3.back * 0.01f);            }        } }}

【弹痕效果】

需要设置弹痕有渐淡消失效果

首先将贴图拖到Quad对象上

自动生成材质

在代码上控制其渐淡效果

using UnityEngine;using System.Collections;public class BulletHole : MonoBehaviour{    private float holeSpeed=150f;    private MeshRenderer r;    private float holeTimer=0.0f;// Use this for initializationvoid Start ()     {        r = this.GetComponent<MeshRenderer>();}// Update is called once per framevoid Update ()     {        holeTimer += Time.deltaTime;        if (holeTimer >= 1.0f)        {            float lerp = Mathf.PingPong(Time.time, holeSpeed) / holeSpeed;            //渐变效果，Color.clear便是空白效果            r.material.color = Color.Lerp(r.material.color, Color.clear, lerp);        }        if(holeTimer>=2.5f)        {            Destroy(this.gameObject);        }}}

之后我们要设置一个子弹发射时，在枪口上有个闪光效果

将其Mesh Rederer组件取消勾选

在代码里控制其显示

using UnityEngine;using System.Collections;public class MuzzleFlashPlay : MonoBehaviour {    private int i=0;    private MeshRenderer mr;    public Material[] mat;    private float flashLifetime = 0.1f;    private float flashTimer = 0.0f;// Use this for initializationvoid Start ()     {       mr = this.GetComponent<MeshRenderer>();}// Update is called once per framevoid Update ()     {        if (Input.GetMouseButtonDown(0))        {            PlayFlash();        }        if (mr.enabled)        {            flashTimer += Time.deltaTime;            if (flashTimer >= flashLifetime)            {                flashTimer = 0;                mr.enabled = false;            }        }        }    void PlayFlash()    {         mr.enabled = true;        mr.material = mat[i];        i++;        if(i>=4)        {            i = 0;        }    }}

效果图如下：
