Unity制作飞机大战第一步
1.把资源包导入Unity并搭建好场景
2.并把做好的预制体 拖入一个新的文件夹
如下图:
飞机控制脚本,此脚本挂在玩家飞机上
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerShipCtr : MonoBehaviour
{
public float MoveSpeed;
public float FireTime;
public GameObject PlayerBullet;
//私有变量同意使用_下划线
private Rigidbody _rig;
private AudioManagerCtr _audioManager;
private float _timer; // 计时器
private GameObject _obj;
private CreateGameManagerCtr _createGameManagerCtr;
void Start()
{
_obj = transform.Find("Protect").gameObject;
FireTime = 0.25f;
_rig = GetComponent<Rigidbody>();
if (null == _rig)
{
_rig = gameObject.AddComponent<Rigidbody>();
}
_rig.useGravity = false;
if (MoveSpeed == 0)
{
MoveSpeed = 5;
}
//找到标签的对象 并得到其组件
_audioManager = GameObject.FindWithTag("AudioManager").GetComponent<AudioManagerCtr>();
_createGameManagerCtr = GameObject.FindWithTag("CreateGameManager").GetComponent<CreateGameManagerCtr>();
_timer = 0;
}
//逻辑
void Update()
{
if(_createGameManagerCtr.PlayerIsProtected)
{
_obj.SetActive(true);
}else
{
_obj.SetActive(false);
}
_timer += Time.deltaTime;
if (Input.GetMouseButton(0) && _timer >= FireTime) //用于判断发射的时间间隔
{
//实例化子弹
_timer = 0;
GameObject obj = Instantiate(PlayerBullet);
obj.transform.position = gameObject.transform.Find("BulletPos").position;
if(obj.tag.Equals(TagManager.PlayBulletName)) // 1发
obj.GetComponent<PlayerBulletCtr>().MoveSpeed = 7;
_audioManager.PlayAudio(1,AudioName.PlyerShoot);
}
}
//物理
void FixedUpdate() //每个固定的物理时间 用于物理引擎的参数更新
{
//edit->Project settings->Input 设置
float _v = Input.GetAxisRaw("Vertical"); //得到垂直轴向输入
float _h = Input.GetAxisRaw("Horizontal"); //得到水平轴向的输入
Vector3 v3 = new Vector3(_h, 0, _v).normalized; //向量归一化 一般用在控制移动 获取方向
_rig.velocity = v3 * MoveSpeed;
//飞机在屏幕中移动的范围
_rig.transform.position = new Vector3(
Mathf.Clamp(_rig.transform.position.x, -6.8f, 6.8f),
0,
Mathf.Clamp(_rig.transform.position.z, -3.5f, 14));
//左右移动时 让飞机有一个30°的倾斜
_rig.transform.rotation = Quaternion.AngleAxis(30 * _h, transform.forward);
}
}
玩家子弹的脚本,此脚本挂在预制体PlayerBullet上
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerBulletCtr : MonoBehaviour {
// Use this for initialization
public float MoveSpeed;
private Rigidbody _rig;
void Start ()
{
// transform.rotation = Quaternion.Euler(90,0,0);
_rig = GetComponent<Rigidbody>();
if (null == _rig)
{
_rig = gameObject.AddComponent<Rigidbody>();
}
_rig.useGravity = false; //子弹重力为false
if(MoveSpeed == 0)
MoveSpeed = 5; //如果为0 就默认子弹速度为5
_rig.velocity = transform.up * MoveSpeed;
}
// Update is called once per frame
void Update () {
}
}
生成陨石和敌机脚本,此脚本挂在CreateGameManager上
建一个空物体 改名为CreateGameManager,用于控制陨石的生成和敌机的生成
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CreateGameManagerCtr : MonoBehaviour {
//x --> -3.5 -2 -0.5 1 2.5 3.5
// 0
// 16
//0 敌机
// 1~3 陨石
//波次 协同
//波次 数量
public GameObject[] EnemyObjects; //敌人的数组(包括陨石和敌机)
//爆炸特效
public GameObject[] ParitcleObjects; //爆炸特效的数组
public GameObject Jack; //拖入预制体玩家子弹
public GameObject[] Bolls; //public一个球的数组 吃了球有特殊功能
public bool PlayerOver;
public bool CellPlayerIsProtected;
public bool PlayerIsProtected;
//存储初始化点的位置
private Vector3[] CreatePos;
private BollCtr _bollctr;
private float _timer;
private PlayerShipCtr _playerShipCtr;
void Start () {
_bollctr = GameObject.FindWithTag("BlueBoll").GetComponent<BollCtr>();
_playerShipCtr = GameObject.FindWithTag(TagManager.PlayName).GetComponent<PlayerShipCtr>();
CellPlayerIsProtected = true;
PlayerIsProtected = true;
PlayerOver = false;
CreatePos = new Vector3[8]; //随机八个位置 让陨石从这些位置生成
for (int i = 0; i < 7; i++)
{
//
CreatePos[i].Set(-6.5f+i*1.8f, 0, 16);
}
CreatePos[CreatePos.Length-1].Set(6.5f,0,16);
StartCoroutine("IEnumCreateEnemy"); //开始协同
}
// Update is called once per frame
void Update ()
{
_timer += Time.deltaTime;
if (CellPlayerIsProtected)
{
PlayerIsProtected = true;
CellPlayerIsProtected = false;
_timer = 0;
}
if (_timer >= 5.0f)
{
PlayerIsProtected = false;
}
if (_bollctr.ISOBJ)
{
StartCoroutine("HEIHEI"); //开始协同
}
}
IEnumerator IEnumCreateEnemy()
{
int EnemyShipCount = 0;
while (true)
{
EnemyShipCount = 0;
int tmpNumber = Random.Range(8, 15); //随机陨石的数量8~15
for (int i = 0; i < tmpNumber; i++) //不管一波生成几个陨石 反正定义顺序三个敌人出现一个敌机
{
EnemyShipCount++;
CreateEnemy(EnemyShipCount); //调用下面CreateEnemy方法
yield return new WaitForSeconds(0.4f);//陨石一个接一个出现 间隔为0.4s
}
yield return new WaitForSeconds(1.5f);//每一波陨石出现的时间间隔为1.5s
}
}
//此协同是为了 玩家吃了蓝色球有特殊子弹 5s钟后特殊子弹消失
IEnumerator HEIHEI()
{
yield return new WaitForSeconds(5.0f); //5s钟后变回原来的子弹
_playerShipCtr.PlayerBullet = Jack;
}
public void CreateEnemy(int shipCount)
{
GameObject tmpGameObject;
if (shipCount % 3 == 0) //如果敌人的数量除以3余0的话 实例化一个敌机
{
//敌机
tmpGameObject = Instantiate(EnemyObjects[0], CreatePos[Random.Range(0, CreatePos.Length)], Quaternion.identity);
tmpGameObject.GetComponent<EnemyShipCtr>().Score = Random.Range(10, 20);
tmpGameObject.GetComponent<EnemyShipCtr>().Left = Random.Range(0, 3);
}
else
{
//陨石
tmpGameObject = Instantiate(EnemyObjects[Random.Range(1,EnemyObjects.Length)], CreatePos[Random.Range(0, CreatePos.Length)], Quaternion.identity);
tmpGameObject.GetComponent<AsteroidCtr>().Score = Random.Range(5, 10);
}
if (shipCount % 4 == 0) //每第四个敌人死亡 生成一个随机球
{
if (tmpGameObject.tag.Equals(TagManager.EnemyShip)) //如果碰撞到的是敌机
{
//实例化随机化球
tmpGameObject.GetComponent<EnemyShipCtr>().Boll = Bolls[Random.Range(0, Bolls.Length)];
}
else
{
tmpGameObject.GetComponent<AsteroidCtr>().Boll = Bolls[Random.Range(0, Bolls.Length)];
}
}
}
public void CreateParticleByV3AndIndex(Vector3 CreatePoint, int index)
{
//实例化例子爆炸特效
GameObject tmpGameObject = Instantiate(ParitcleObjects[index], CreatePoint, Quaternion.identity);
Destroy(tmpGameObject,2f); //两秒后销毁特效
}
public void StopGame()
{
PlayerOver = true;
StopCoroutine("IEnumCreateEnemy"); //停止协同
}
}
