Flappy Bird 一款C语言小游戏（图形优化版）（成功解决EasyX中putimage()未能实现第二张图片显示问题）

首先要下载EasyX库，如果网上找不到或者想要老版本的可以在评论区或者直接私信我

首先导入图片

#include
#include

int main()
{
	initgraph(350, 600);
	IMAGE img_bk;			//define IMAGE对象
	loadimage(&img_bk, "D:\\background.jpg");		//读取图片到IMAGE对象
	putimage(0, 0, &img_bk);
	IMAGE img_bd;
	loadimage(&img_bd, "D:\\bird2.jpg");
	putimage(100, 200, &img_bd);
	getch();				//等待输入，以防立刻退出
	closegraph();
	return 0;
}

图片资源：
bird2.jpg

background.jpg

运行效果如下：

遮罩图使用

由于小鸟无法完美融入背景，所以我们需要遮罩图

详细代码如下：

#include
#include

int main()
{
	initgraph(350, 600);
	IMAGE img_bk;			//define IMAGE对象
	loadimage(&img_bk, "D:\\background.jpg");		//读取图片到IMAGE对象
	putimage(0, 0, &img_bk);
	IMAGE img_bd1, img_bd2;
	loadimage(&img_bd1, "D:\\bird1.jpg");
	loadimage(&img_bd2, "D:\\bird2.jpg");
	putimage(100, 200, &img_bd1, NOTSRCERASE);
	putimage(100, 200, &img_bd2, SRCINVERT);
	getch();				//等待输入，以防立刻退出
	closegraph();
	return 0;
}

重新修改优化版（实现了跳出失败图形页面）

花了很长时间一直在琢磨一个问题，为什么连Game Over音效都出来了而Game Over的图片不能显示出来，页面上仍是背景图

我做了很多次实验

比方说这个：目的是检验putimage能不能让程序先后显示两张背景图

#include
#include
#include
#include
#include
#include


#pragma comment(lib, "Winmm.lib")

int main()
{
	initgraph(350, 600);
	IMAGE img_bk;			//define IMAGE对象
	IMAGE img_fail;
	loadimage(&img_bk, "D:\\background.jpg");		//读取图片到IMAGE对象
	loadimage(&img_fail, "D:\\failed.png");
	putimage(0, 0, &img_bk);		//显示背景
	mciSendString("open D:\\tb.mp3 alias bkmusic", NULL, 0, NULL);		//打开音乐
	mciSendString("play bkmusic repeat", NULL, 0, NULL);		//循环播放
	Sleep(600);
	loadimage(&img_fail, "D:\\failed.png");
	mciSendString("close bkmusic", NULL, 0, NULL);
	Sleep(1);
	putimage(0, 0, &img_fail);
	mciSendString("close fdmusic", NULL, 0, NULL);
	mciSendString("open D:\\failed2.mp3 alias fdmusic", NULL, 0, NULL);
	mciSendString("play fdmusic", NULL, 0, NULL);
	Sleep(10);
	system("pause");
	exit(0);
}

答案是可以的，但是为什么大体框架都差不多，都是为了实现先后输出两个不一样的背景图，但前者可以实现，后者却毫无动静，为此我又在网上找了各种相关的解答，用了getimage()函数，后来发现其函数本身就不是用来解决这个的，后来又用messagebox函数，好用是好用，但是仍不能达到我想要的那种效果，毕竟弹出那么小的弹窗告诉你失败了，感觉太轻巧了。。。

最终我想到了一个办法，就是先让前面的图片清空，再加载另外背景图，终于实现了（虽然我不知道为什么putimage()在大型一点的代码里就不起作用了，如果有知道的朋友欢迎来评论区抒发自己的看法）
