1、场景设置

图片展示在开始时，设置Lighting Settings中的Scene场景的自动渲染功能取消，这样会节省时间，一般发布时再渲染。同时渲染场景，将图中颜色映射到整个场景中渲染后的效果如图所示：再Main camera中选择正交视野

2、控制坦克的前后左右移动

给坦克添加冒烟的特效：

在Prefabs中有DustTrail就是冒烟特效，将特效用Ctrl+D复制一份，分别拖到履带下

给坦克添加Box Collider

关于Box Collider详情可查看Unity Manual——Box Collider文档

添加刚体组件

4.控制坦克前后移动：代码如下

using System.Collections;using System.Collections.Generic;using UnityEngine;public class TankMovement : MonoBehaviour{ //定义速度 public float speed = 5; //定义刚体 private Rigidbody rigidbody; // Start is called before the first frame update void Start() { //得到Rigidbody rigidbody = this.GetComponent<Rigidbody>(); } // Update is called once per frame void Update() { //得到前后的按键,v是一个-1到1的值 float v = Input.GetAxis("Vertical"); //通过刚体组件给它施加一个速度 rigidbody.velocity = transform.forward * v * speed; } }

GetCompoment ()函数：GetCompoment ()从当前游戏对象获取组件T，只在当前游戏对象中获取，没得到的就返回null，不会去子物体中去寻找。详解：CSDN文档

Input.GetAxis()函数：一、触屏类1、Mouse X 鼠标沿屏幕X移动时触发2、Mouse Y 鼠标沿屏幕Y移动时触发3、Mouse ScrollWheel 鼠标滚轮滚动是触发二、键盘类1、Vertical 键盘按上或下键时触发2、Horizontal 键盘按左或右键时触发返回值是一个数，正负代表方向官方文档：Input.GetAxis()函数

transform.forward函数：transform.forward的值则等于当前物体的自身坐标系z轴在世界坐标上指向详解：CSDN文档

同时由于坦克只在XZ轴运动，所以我们要把Y轴锁定；并且坦克只需要绕着Y轴旋转，所以把XZ轴锁定

控制坦克左右移动：

using System.Collections;using System.Collections.Generic;using UnityEngine;public class TankMovement : MonoBehaviour{ //定义速度 public float speed = 5; //定义转速 public float angularSpeed = 30; //定义刚体 private Rigidbody rigidbody; // Start is called before the first frame update void Start() { //得到Rigidbody rigidbody = this.GetComponent<Rigidbody>(); } // Update is called once per frame void Update() { //得到前后的按键,v是一个-1到1的值 float v = Input.GetAxis("Vertical"); //通过刚体组件给它施加一个速度 rigidbody.velocity = transform.forward * v * speed; //控制物体旋转 float h = Input.GetAxis("Horizontal"); rigidbody.angularVelocity = transform.up * h * angularSpeed; } }

坦克的参数也可以在这里更改

用WASD控制坦克1，用方向键控制坦克2a）打开Prioect Settingsb）复制两遍Horizontal轴c）Vertical也是如此

d）代码如下：

using System.Collections;using System.Collections.Generic;using UnityEngine;public class TankMovement : MonoBehaviour{ //定义速度 public float speed = 20; //定义转速 public float angularSpeed = 5; //给每个坦克一个编号,通过编号区分不同的控制 public float number = 1; //定义刚体 private Rigidbody rigidbody; // Start is called before the first frame update void Start() { //得到Rigidbody rigidbody = this.GetComponent<Rigidbody>(); } // Update is called once per frame void Update() { //得到前后的按键,v是一个-1到1的值 float v = Input.GetAxis("VerticalPlayer"+number); //通过刚体组件给它施加一个速度 rigidbody.velocity = transform.forward * v * speed; //控制物体旋转 float h = Input.GetAxis("HorizontalPlayer"+number); rigidbody.angularVelocity = transform.up * h * angularSpeed; } } 3、子弹

控制坦克子弹发射在Model里面的Shell先给子弹添加一个胶囊碰撞器

关于胶囊碰撞器的官方文档：胶囊碰撞器再创建刚体Rigidbody

将其作为预制体后，创建一个空对象，用来确定子弹发射位置并添加TankAttack脚本来控制子弹的发射代码如下：

using System.Collections;using System.Collections.Generic;using UnityEngine;public class TankAttack : MonoBehaviour{ public GameObject shellPrefab; private Transform firePosition; //发射键,默认为空格键 public KeyCode fireKey = KeyCode.Space; // Start is called before the first frame update void Start() { firePosition = transform.Find("FirePosition"); } // Update is called once per frame void Update() { //如果按键按下 if(Input.GetKeyDown(fireKey)) { //实例化,发射方向和炮筒方向保持一致 GameObject.Instantiate(shellPrefab,firePosition.position,firePosition.rotation); } }}

控制炸弹的飞行和爆炸控制子弹的速度

using System.Collections;using System.Collections.Generic;using UnityEngine;public class TankAttack : MonoBehaviour{ public GameObject shellPrefab; private Transform firePosition; public float shellSpeed = 10; //发射键,默认为空格键 public KeyCode fireKey = KeyCode.Space; // Start is called before the first frame update void Start() { firePosition = transform.Find("FirePosition"); } // Update is called once per frame void Update() { //如果按键按下 if(Input.GetKeyDown(fireKey)) { //实例化,发射方向和炮筒方向保持一致 //每次实例化一个子弹时，得到子弹的刚体组件，再通过刚体组件给它速度 GameObject go = GameObject.Instantiate(shellPrefab,firePosition.position,firePosition.rotation)as GameObject; //给刚体组件一个速度 go.GetComponent<Rigidbody>().velocity = go.transform.forward * shellSpeed; } }}

在Shell中添加脚本控制其爆炸并将刚体组件选为触发器

using UnityEngine;using System.Collections;public class Shell : MonoBehaviour { public GameObject shellExplosionPrefab; //触发检测 //只要进行触发，就爆炸，参数表示跟哪个碰撞器接触 public void OnTriggerEnter( Collider collider ) { GameObject.Instantiate(shellExplosionPrefab, transform.position, transform.rotation); GameObject.Destroy(this.gameObject); }}

同时给爆炸特效添加一个脚本，控制其自动销毁

using UnityEngine;using System.Collections;public class DestroyForTime : MonoBehaviour { public float time;// Use this for initializationvoid Start () { Destroy(this.gameObject,time);}// Update is called once per framevoid Update () {}}

3.控制炸弹对坦克的伤害给坦克加一个Tank的标签，用以区分它是不是坦克。这样子弹就可以检测它触碰到的是不是坦克，就可以给坦克伤害

using UnityEngine;using System.Collections;public class Shell : MonoBehaviour { public GameObject shellExplosionPrefab; public void OnTriggerEnter( Collider collider ) { GameObject.Instantiate(shellExplosionPrefab, transform.position, transform.rotation); GameObject.Destroy(this.gameObject);//如果检测到的是坦克，给坦克发消息 if (collider.tag == "Tank") { collider.SendMessage("TakeDamage"); } }}

坦克收到消息后减少血量

using UnityEngine;using System.Collections;using UnityEngine.UI;public class TankHealth : MonoBehaviour { public int hp = 100; public GameObject tankExplosion;// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {} void TakeDamage() { if (hp <= 0) return; hp -= Random.Range(10, 20); hpSlider.value = (float)hp /hpTotal; if (hp <= 0) {//收到伤害之后 血量为0 控制死亡效果 GameObject.Instantiate(tankExplosion, transform.position + Vector3.up, transform.rotation); GameObject.Destroy(this.gameObject); } }} 4、控制相机视野的跟随

将视野设置在两个坦克的正中心

using UnityEngine;using System.Collections;public class FollowTarget : MonoBehaviour { public Transform player1; public Transform player2; private Vector3 offset;// Use this for initializationvoid Start () {//相机的位置减去中心的位置就得到了初始的偏移 offset = transform.position - (player1.position + player2.position)/2;}// Update is called once per framevoid Update () { transform.position = (player1.position + player2.position)/2 + offset;}}

现在让视野跟着举距离进行变大变小

using UnityEngine;using System.Collections;public class FollowTarget : MonoBehaviour { public Transform player1; public Transform player2; private Vector3 offset; private Camera camera;// Use this for initializationvoid Start () { offset = transform.position - (player1.position + player2.position)/2; camera = this.GetComponent<Camera>();}// Update is called once per framevoid Update () {//如果有一个被销毁了，就不做跟随了 if (player1 == null || player2 == null) return; transform.position = (player1.position + player2.position)/2 + offset; float distance = Vector3.Distance(player1.position, player2.position); float size = distance*0.58f; //正交距离 camera.orthographicSize = size;}} 5、添加音效

1.背景音效：创建一个空对象，用它来播放背景音乐2.坦克爆炸时的音效

using UnityEngine;using System.Collections;using UnityEngine.UI;public class TankHealth : MonoBehaviour { public int hp = 100; public GameObject tankExplosion; public AudioClip tankExplosionAudio; public Slider hpSlider; private int hpTotal;// Use this for initializationvoid Start () { hpTotal = hp;}// Update is called once per framevoid Update () {} void TakeDamage() { if (hp <= 0) return; hp -= Random.Range(10, 20); hpSlider.value = (float)hp /hpTotal; if (hp <= 0) {//收到伤害之后 血量为0 控制死亡效果 //表示播放某一个音效，在某一个点 AudioSource.PlayClipAtPoint(tankExplosionAudio,transform.position); GameObject.Instantiate(tankExplosion, transform.position + Vector3.up, transform.rotation); GameObject.Destroy(this.gameObject); } }}

3、子弹发射的声音

using UnityEngine;using System.Collections;public class TankAttack : MonoBehaviour { public GameObject shellPrefab; public KeyCode fireKey = KeyCode.Space; public float shellSpeed = 10; public AudioClip shotAudio; private Transform firePosition;// Use this for initializationvoid Start () { firePosition = transform.Find("FirePosition");}// Update is called once per framevoid Update () { if (Input.GetKeyDown(fireKey)) { AudioSource.PlayClipAtPoint(shotAudio,transform.position); GameObject go = GameObject.Instantiate(shellPrefab, firePosition.position, firePosition.rotation) as GameObject; go.GetComponent<Rigidbody>().velocity = go.transform.forward*shellSpeed; }}}

4、子弹爆炸的声音

using UnityEngine;using System.Collections;public class Shell : MonoBehaviour { public GameObject shellExplosionPrefab; public AudioClip shellExplosionAudio; public void OnTriggerEnter( Collider collider ) { AudioSource.PlayClipAtPoint(shellExplosionAudio,transform.position); GameObject.Instantiate(shellExplosionPrefab, transform.position, transform.rotation); GameObject.Destroy(this.gameObject); if (collider.tag == "Tank") { collider.SendMessage("TakeDamage"); } }}

5、坦克行走时的音效

using UnityEngine;using System.Collections;using UnityEditor;public class TankMovement : MonoBehaviour { public float speed = 5; public float angularSpeed = 30; public float number = 1; //增加一个玩家的编号，通过编号区分不同的控制 //得到两个声音 public AudioClip idleAudio; public AudioClip drivingAudio;//得到声音源的组件 private AudioSource audio; private Rigidbody rigidbody;// Use this for initializationvoid Start () { rigidbody = this.GetComponent<Rigidbody>(); audio = this.GetComponent<AudioSource>();} void FixedUpdate() { float v = Input.GetAxis("VerticalPlayer"+number); rigidbody.velocity = transform.forward*v*speed; float h = Input.GetAxis("HorizontalPlayer"+number); rigidbody.angularVelocity = transform.up*h*angularSpeed;//如果开始行走 if (Mathf.Abs(h) > 0.1 || Mathf.Abs(v) > 0.1) { //修改默认的声音播放源 audio.clip = drivingAudio; //如果当前没有播放 if(audio.isPlaying==false) audio.Play(); } else { audio.clip = idleAudio; if (audio.isPlaying == false) audio.Play(); } }} 6、创建血条

先创建一个滑动器先将Handle Slide Area先删除掉将背景改为圆圈将File也修改为圆圈将Image Type 修改为Filed填充模式最后将这个血条修改为3D模式将画布的大小修改为40×40将Slider的中心修改为0，0

最后在TankHealth中修改血条

using UnityEngine;using System.Collections;using UnityEngine.UI;public class TankHealth : MonoBehaviour { public int hp = 100; public GameObject tankExplosion; public AudioClip tankExplosionAudio; public Slider hpSlider;//添加一个血条总量 private int hpTotal;// Use this for initializationvoid Start () { hpTotal = hp;}// Update is called once per framevoid Update () {} void TakeDamage() { if (hp <= 0) return; hp -= Random.Range(10, 20); //将比值赋值给value hpSlider.value = (float)hp /hpTotal; if (hp <= 0) {//收到伤害之后 血量为0 控制死亡效果 AudioSource.PlayClipAtPoint(tankExplosionAudio,transform.position); GameObject.Instantiate(tankExplosion, transform.position + Vector3.up, transform.rotation); GameObject.Destroy(this.gameObject); } }}

最终效果
