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：

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：

bool fileExist(const char* name) {

	if (fp == NULL) {
		return false;
	}
	else {
		fclose(fp);

将图片显示在窗口上：

游戏场景动作的实现：
