学习笔记适合新手，如有错误请指正。？号处也请各位指点下，谢谢。
建立一个场景》新建一个Plane作为地面》在创建一组Cube作为一个小屋
把Direction Light的Intensity设置为0.2模拟夜晚的感觉
在创建一个Point Light并置于小屋的天花板
在创建一个player，其下有一个子对象Gun枪，Gun下继续创建一个子对象“GunShotEffect”
上面加上LineRenderer子弹轨迹和开枪的效果Particle System和Point Light
最后新建一个Animator Controller并命名为“PlayerController”里面有Idle和Moving两个状态
为摄像机增加脚本，使其跟随并观察Player，脚本代码如下：
CamPos.cs
using UnityEngine; using System.Collections; public class CamPos : MonoBehaviour { public float back = 3f; public float height = 1f; public Transform player; public float moveFac; Vector3 targetPos; void LateUpdate() { //设置摄像机的目标位置在主角的后上方 targetPos = player.transform.position + -back * player.forward + new Vector3 (0f, height, 0f); //摄像机位置逐渐移动至目标位置 transform.position = new Vector3 (Mathf.Lerp (transform.position.x, targetPos.x, 11), Mathf.Lerp (transform.position.y, targetPos.y, 5), Mathf.Lerp (transform.position.z, targetPos.z, 11)); //摄像机观察主角 transform.LookAt (player); } }
PlayerManager.cs
using UnityEngine; using System.Collections; public class PlayerManager : MonoBehaviour { public float rotationSpeed; public float moveSpeed; public ParticleSystem gunShotEffect; public GameObject gunShotLight; public AudioSource gunShotSound; private bool isShooting = false; private Animator animator; private Rigidbody rigidbody; void Start () { animator = GetComponent<Animator>(); rigidbody = GetComponent<Rigidbody>(); } void Update () { //锁定鼠标光标并隐藏 Cursor.lockState = CursorLockMode.Locked; Cursor.visible = false; //处理移动 Moving(); //处理旋转 Rotating (); //按下鼠标左键射击 if (Input.GetMouseButtonDown (0)) { GunShotStart(); } //按下ESC键退出游戏 if (Input.GetKey (KeyCode.Escape)) { #if !UNITY_EDITOR Application.Quit(); #else UnityEditor.EditorApplication.isPlaying = false; #endif } } void Moving() { float x = Input.GetAxis ("Horizontal"); Vector3 mH = x * transform.right.normalized * moveSpeed * Time.deltaTime; rigidbody.MovePosition(rigidbody.position+mH); float y = Input.GetAxis ("Vertical"); Vector3 mV = y * transform.forward.normalized * moveSpeed * Time.deltaTime; rigidbody.MovePosition(rigidbody.position+mV); bool moving = x != 0 || y != 0; animator.SetBool ("IsMoving", moving); } void Rotating() { float asixX = Input.GetAxis ("Mouse X"); transform.eulerAngles += new Vector3 (0, rotationSpeed *Time.deltaTime*asixX, 0); } void GunShotStart() { if(isShooting) return; isShooting = true; gunShotLight.SetActive(true); gunShotEffect.Play(); gunShotSound.Play(); Invoke("GunShotEnd",0.1f); } void GunShotEnd() { isShooting = false; gunShotLight.SetActive (false); } }
首先，新建一个Audio Source并命名为Music，指定AudioClip为Background Music，勾选Loop将Spatial Blend设置为0
新建一个Audio Source并命名为GunShotSound，指定AudioClip为Player GunShot，取消勾选Play On Awake将Spatial Blend设置为1
在PlayerManager脚本里添加一个AudioSource参数，并在GunShotStart（）函数里播放playeraManager脚本代码如下：
using UnityEngine; using System.Collections; public class PlayerManager : MonoBehaviour { public float rotationSpeed; public float moveSpeed; public ParticleSystem gunShotEffect; public GameObject gunShotLight; public AudioSource gunShotSound; private bool isShooting = false; private Animator animator; private Rigidbody rigidbody; void Start () { animator = GetComponent<Animator>(); rigidbody = GetComponent<Rigidbody>(); } void Update () { //锁定鼠标光标并隐藏 Cursor.lockState = CursorLockMode.Locked; Cursor.visible = false; //处理移动 Moving(); //处理旋转 Rotating (); //按下鼠标左键射击 if (Input.GetMouseButtonDown (0)) { GunShotStart(); } //按下ESC键退出游戏 if (Input.GetKey (KeyCode.Escape)) { #if !UNITY_EDITOR Application.Quit(); #else UnityEditor.EditorApplication.isPlaying = false; #endif } } void Moving() { float x = Input.GetAxis ("Horizontal"); Vector3 mH = x * transform.right.normalized * moveSpeed * Time.deltaTime; rigidbody.MovePosition(rigidbody.position+mH); float y = Input.GetAxis ("Vertical"); Vector3 mV = y * transform.forward.normalized * moveSpeed * Time.deltaTime; rigidbody.MovePosition(rigidbody.position+mV); bool moving = x != 0 || y != 0; animator.SetBool ("IsMoving", moving); } void Rotating() { float asixX = Input.GetAxis ("Mouse X"); transform.eulerAngles += new Vector3 (0, rotationSpeed *Time.deltaTime*asixX, 0); } void GunShotStart() { if(isShooting) return; isShooting = true; gunShotLight.SetActive(true); gunShotEffect.Play(); gunShotSound.Play(); Invoke("GunShotEnd",0.1f); } void GunShotEnd() { isShooting = false; gunShotLight.SetActive (false); } }
运行场景，角色已经能正常移动和射击了
接着我们来添加音效，新建一个Audio Mixer，在其下再创建两个子组Music和Sound
将Music游戏对象的Audio Soucre的Output指定为Music
将GunShotSound游戏对象的Audio Soucre的Output指定为Sound，分别为两个组添加Duck Volume和Send并进行设置
然后是添加混响，屋里开枪的话会有混响效果，这里的混响和Audio Reverb Zone不同，属于Audio Effect，需要我们自己去控制，只是音效需要混响，背景音乐不需要，所以选中Sound组点击Add，在点击SFX Reverb添加，如图所示：
当Room参数为-10000时没有混响，当为0时混响效果打到最大，所以我们用这个参数作为混响的开关
将鼠标光标移至其上并点击鼠标右键“Expose Room（of Sound》SFX Reverb）to Script”那么我们就可以在脚本里对其进行取值和赋值操作了
新建一个空的游戏对象并命名为ReverbTriggerZone，添加BoxCollider组件并勾选Is Trigger设置其位置和大小，匹配小屋并置于其中，然后添加脚本，如下：
using UnityEngine; using System.Collections; using UnityEngine.Audio; public class ReverbTriggerZone : MonoBehaviour { public AudioMixer mixer; public AudioMixerSnapshot snapshotNoReverb; public AudioMixerSnapshot snapshotReverb; void OnTriggerEnter(Collider other) { //当不是玩家进入时，不处理 if (other.name != "Player") return; //开启混响 mixer.SetFloat ("MyExposedParam", 0); } void OnTriggerExit(Collider other) { //当不是玩家进入时，不处理 if (other.name != "Player") return; //关闭混响 mixer.SetFloat ("MyExposedParam", -10000); } }
我们还可以使用另外一种方式：快照（Snapshot），相当于将设置保存在一张快照里，以供运行时读取不同设置
回到Audio Mixer窗口，在Snapshots栏点击“+”增加两个快照，一个起名NoReverb，设置Room为-1000；一个起名为Reverb设置Room为0
场景启动时人物在屋子外，没有混响，一次要将NoReverb设置为默认快照
对着NoReverb点击鼠标右键》Set as start Snapshot。
在NoReverb的右侧显示五角星团代表其为默认快照
ReverbTriggerZone脚本如下：
using UnityEngine; using System.Collections; using UnityEngine.Audio; public class ReverbTriggerZone : MonoBehaviour { public AudioMixer mixer; public AudioMixerSnapshot snapshotNoReverb; public AudioMixerSnapshot snapshotReverb; void OnTriggerEnter(Collider other) { //当不是玩家进入时，不处理 if (other.name != "Player") return; //开启混响 //mixer.SetFloat ("MyExposedParam", 0); snapshotReverb.TransitionTo (0.1f); } void OnTriggerExit(Collider other) { //当不是玩家进入时，不处理 if (other.name != "Player") return; //关闭混响 //mixer.SetFloat ("MyExposedParam", -10000); snapshotNoReverb.TransitionTo (0.1f); } }
运行发现两者的效果完全一样
