写代码前的准备工作

搭建项目环境easyx：

要想在我们的窗口实现图片交互

应该给编译器安装 easyx 图形库

这边我用图片展示详细的安装操作

（1）我们先在网页找到官网

（2）然后点击下载

（3）将 easyx 安装到目标编译器

（4）出现安装成功就代表可以使用了

接下来我们就可以写放心写代码啦！！！

导入游戏素材：

在当前项目的目录下创建文件夹，并把解压好的文件拷贝进去

修改项目属性：

<1>点击项目找到项目属性

<2>将字符集改成多字符集

这里图片操作的时候需要

<3>将编译器对SDL的检查关掉

这里检查文件是否存在的时候需要

导入我们的辅助项目：

游戏页面的实现：

		}
		EndBatchDraw();              //结束绘图
	}
}

双缓冲绘图：

BeginBatchDraw() - 开始双缓冲

EndBatchDraw() - 结束双缓冲

双缓冲区：打印一个的同时显示另一个，不断重复这个过程，避免了屏幕闪耀问题

游戏的背景初始化：

判断读取文件是否存在：

	if (fp == NULL) {

	}
	else {

将图片显示在窗口上：

游戏场景动作的实现：

void updateGame() {
	//更新植物动作
	for (int i = 0; i < 3; i++) {

	//创建僵尸

	//创建豌豆子弹
	createBullets();	
	//更新豌豆子弹动作

	//豌豆子弹与僵尸碰撞

}
