大佬教程收集整理的这篇文章主要介绍了【cocos2d-x 3.7 飞机大战】 决战南海I (四) 敌机管理，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

敌方飞机应该不定时的出现，有自己的生命周期、运动轨迹。这个类用来管理敌机的产生、移动、爆炸、销毁等。

敌机管理类主要函数如下
@H_
489_0@
@H_
489_0@
@H_
262_22@ //绑定控制器(更新分数)
void bindController(Controller* controller
);
//根据分数决定添加敌机速度
void addSpeed(float dt
);
// 添加敌机1
void addEnemy1(float dt
);
// 添加敌机2
void addEnemy2(float dt
);
// 添加敌机3
void addEnemy3(float dt
);
// 添加敌机4
void addEnemy4(float dt
);
// 敌机爆炸
void blowupEnemy(Enemy* pEnemySprit
E);
// 移除敌机pNode
void removeEnemy(Node *pNod
E);
@H_
489_0@
其成员变量如下
@H_
262_22@Vector<Enemy*> vecEnemy;// 敌机容器，用于遍历碰撞问题
Controller* m_controlLayer; //控制器
float m_fSpeed; //添加敌机速度
float m_fEnemy1;
float m_fEnemy2;
float m_fEnemy3;
float m_fEnemy4;
@H_
489_0@
敌机产生后，要先存储在容器中，通过容器来进行与子弹、我方飞机的碰撞检测，之后统一销毁。
@H_
489_0@
@H_
489_0@
还有就是，因为分数是要存储在数据库中的，所以我们用一个控制器来管理分数。对于我方飞机的触摸移动，也可以用控制器来控制，由于本游戏中的我方飞机操作简单，代码就嵌在了我方飞机类中。(⊙o⊙)…扯远了，先介绍敌机管理类的实现，再讲控制器。

} 每种类型的敌机的爆炸代码比较短，直接在init()函数中进行初始化。为了使游戏难度不断增加，会根据分数来改变添加敌机的速度。敌机的运动轨迹大同小异，不过贝塞尔曲线看起来确实挺不错的。
