导入两个头文件
#include <graphics.h> // 引入 EasyX 的图形库头文件
#include <conio.h> // 引入 conio.h 以使用 getch()窗口创建函数：小黑屏
initgraph(640, 480, SHOWCONSOLE);
closegraph(); //关闭一个窗口设置背景颜色：这里设置完颜色之后，还需要清除一下设备，不然还是黑色的
setbkcolor(WHITE); //设置背景颜色
cleardevice(); //清屏，把黑色清楚掉......每画一个东西，都需要清除一次绘图函数：（这里以画圆为例），前缀是需要绘图的类型，后缀是种类
circle()无填充
fillcircle()有边框填充
solidcircle()无边框填充下面是使用方式：
circle(50, 50, 50);
fillcircle(50, 150, 50);
solidcircle(50, 250, 50);设置类：这个是窗口下的形状
setlinestyle(PS_SOLID, 5); //设置线条样式 setlinestyle(样式，宽度)
setfillcolor(YELLOW); //设置填充颜色 setfillcolor(颜色)
setlinecolor(BLUE); //设置线条边框颜色 setlinecolor设置文字的函数：
//设置文字颜色
settextcolor(RED);
//设置文字样式
settextstyle(20, 0, "楷体");
//设置背景模式
//变成透明TRANSPARENT
setbkmode(TRANSPARENT);
输出文字：
outtextxy(50, 50, "azlml");文字居中的方法：
//把文字居中的操作，画图理解
fillrectangle(200, 50, 500, 100); //画一个矩形
settextcolor(RGB(0, 0, 14));
char arr[] = "居中显示";
int width = 300 / 2 - textwidth(arr) / 2;
int hight = 50 / 2 - textheight(arr) / 2;
outtextxy(width + 200, hight + 50, arr);有关图片的函数：
IMAGE img; //定义一个对象
//加载图片
// 用的是相对路径 ./表示当前文件夹下 ../当前文件夹的上一级目录
//绝对路径 C:\Users\傅\source\repos\项目\项目\小鸟游六花.jpg
//jpg支持背景透明，png不支持背景透明
loadimage(&img, "./小鸟游六花.jpg", 250, 250); //可以调整图片的大小，不是在输出的时候改
//输出图片
putimage(0, 0, &img);有关键盘的函数：
kbhit() //判断是有键盘有被按下
char key = _getch(); //读键盘的消息键盘的操作：
if (kbhit()) //判断是否有键盘按下
{//键盘消息char key = _getch();printf("%d%c\n", key, key);switch (key){//上键case 'w':case 'W':yy--;printf("上键\n");break;case 's':case 'S':yy++;printf("下键\n");break;case 'a':case 'A':xx--;printf("左键\n");break;case 'd':case 'D':xx++;printf("右键\n");break;}
}鼠标操作：
//鼠标消息
if (MouseHit())
{MOUSEMSG msg = GetMouseMsg();// 消息分发switch (msg.uMsg){case WM_LBUTTONDOWN:outtextxy(400, 400, "鼠标左键按下");if (msg.x > 200 && msg.x < 500 && msg.y>50 && msg.y < 200) //在框框内{printf("在框框内\n");//输出鼠标点击的坐标printf("坐标(%d,%d)\n", msg.x, msg.y);}break;case WM_RBUTTONDOWN:outtextxy(400, 400, "鼠标右键按下");if (msg.x > 200 && msg.x < 500 && msg.y>50 && msg.y < 200) //在框框内{printf("在框框内\n");//输出鼠标点击的坐标printf("坐标(%d,%d)\n", msg.x, msg.y);}break;}
