图片相关的准备工作完成后,我们开始想想如何用代码实现这个游戏。回忆一下之前讲过的关于面向对象风格编程的理论。我们把上述的图形元素的共性提取出来,成为一个基础对象,其他对象均继承于这个基础对象。游戏编程中,我们常常把游戏中出现的各种图形元素称作“精灵”。因此,我们把这个基础对象命名为 sprite 。
精灵它们都会在屏幕中移动,肯定需要记录当前的坐标。另外,它们所占有的大小各不相同,也就是拥有自己的宽度和高度。
除此之外,精灵都是需要被绘制到画面上的,所以精灵拥有一个名为 draw 的方法。精灵不能总是待在一个地方不动。所以,精灵还需要一个 update 方法,用于更新精灵内部的数据。后续的代码中,我们会保证每一帧都执行一次每一个精灵的 draw 方法和 update 方法。这样,我们就能保证所有精灵都被正常绘制,并且数据被及时的更新
sprite.h
struct sprite {
//函数指针保存方法:
void(*draw)(struct sprite*);
void(*updata)(struct sprite*);
//基本数据:
int x;
int y;
int width;
int hight;
};
1.我们的父目录:
两个方法,x,y,宽和高;
2.两个图像(mask+img)的指针数组:
3.飞机的状态:
4.飞机的生命数值值:
5.飞机或者的计数器(作用:不要让飞机生成的太快:)

1.对于一个代码来说写一部分运行一部分这样如果有错误也可以及时的发现:
2.定义一个场景对象:
3.实现对于一个场景的绘制,数据更新,鼠标消息,判断场景结束:

#include

//绘制
void (*draw)(struct scene*);
//数据更新
void (*update)(struct scene*);
//鼠标消息的获取

//判断场景是否结束
bool (*isQuit)(struct scene*);
};
1.主要场景的对象:
2.成员变量:
1.场景对象必备父成员
2.英雄飞机:……
3.背景图片……

2.在主要场景中引入一个顺序表成员变量:
3.通过对一个顺序表的循环遍历去实现绘制飞机和场景:

//1.场景元素的绘制:

//1.加入bk和hero到顺序表中:

s->vecElements.append(&s->vecElements, s->bk);
for (int i = 0; i < s->vecElements.size; i++)
{
//获取数据
struct sprite* tmp = (struct sprite*)( &s->vecElements.PData[i]);
//绘制数据

}
}
//2.场景数据的更新:

{
//获取数据
struct sprite* tmp = (struct sprite*)(&s->vecElements.PData[i]);
