贪吃蛇实现的技术前提:
c语言函数、枚举、结构体、动态内存管理、预处理指令、链表、Win32 API等。
Win32 API介绍
Win32 API(Windows API)是指微软公司为Windows操作系统提供的应用程序编程接口(Application Programming Interface)。它是一组函数、数据结构、常量和其他定义,用于开发Windows平台上的应用程序。
Win32 API提供了许多功能,涵盖了操作系统的各个方面,包括图形界面、输入输出、文件系统、网络通信、多线程、安全性等。开发者可以使用这些API来创建各种类型的应用程序,包括桌面应用程序、游戏、驱动程序、系统工具等。
Win32 API基于C语言编写,提供了一种与操作系统交互的标准接口。开发者可以通过调用API函数来访问操作系统的功能和资源,实现各种操作,例如创建窗口、绘制图形、处理用户输入、读写文件、访问网络等。
使用Win32 API进行开发需要一定的编程知识和理解操作系统的工作原理。开发者需要了解API函数的参数、返回值和使用方法,以及如何处理错误和异常情况。此外,开发者还可以利用各种开发工具和框架,简化Win32 API的使用过程,提高开发效率。
总之,Win32 API是Windows平台上开发应用程序的基础,通过使用这些API,开发者可以充分利用操作系统的功能,创建出各种强大、高效的应用程序。
控制台程序(console)
在cmd里面输入mode con cols=100 lines=30就可以控制命令提示符界面的大小
title 名字可以改命令符操作名字
控制台屏幕上的坐标
COORD是Windows API中定义的一个结构体,表示一个字符在控制台屏幕上的坐标。
typedef struct _COORD { SHORT X;//横坐标 SHORT Y;//纵坐标} COORD, *PCOORD;
给坐标赋值:
COORD pos={ 40,10 };
GetStdHandle
GetStdHandle是⼀个Windows API函数。它用于从⼀个特定的标准设备(标准输入、标准输出或标准错误)中取得⼀个句柄(用来标识不同设备的数值),使用这个句柄可以操作设备。
HANDLE GetStdHandle(DWORD nStdHandle);
实例:
HANDLE hOutput = NULL;//获取标准输出的句柄(⽤来标识不同设备的数值) hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
GetConsoleCursorInfo
检索有关指定控制台屏幕缓冲区的光标大小和可见性的信息。
BOOL WINAPI GetConsoleCursorInfo(HANDLE hConsoleO PCONSOLE_CURSOR_INFO lpConsoleCursorInfo);
实例:
HANDLE hOutput = NULL;//获取标准输出的句柄(⽤来标识不同设备的数值) hOutput = GetStdHandle(STD_OUTPUT_HANDLE);CONSOLE_CURSOR_INFO CursorInfo;GetConsoleCursorInfo(hOutput, &CursorInfo);//获取控制台光标信息
CONSOLE_CURSOR_INFO
这个结构体,包含有关控制台光标的信息
typedef struct _CONSOLE_CURSOR_INFO { DWORD dwSize; BOOL bVisible;} CONSOLE_CURSOR_INFO, *PCONSOLE_CURSOR_INFO;
dwSize,由光标填充的字符单元格的百分比。此值介于1到100之间。光标外观会变化,范围从完 全填充单元格到单元底部的水平线条。bVisible,游标的可见性。如果光标可见,则此成员为TRUE。 1 CursorInfo.bVisible = false; //隐藏控制台光标
SetConsoleCursorInfo
设置指定控制台屏幕缓冲区的光标的大小和可见性。
BOOL WINAPI SetConsoleCursorInfo( HANDLE hConsoleOutput, const CONSOLE_CURSOR_INFO *lpConsoleCursorInfo);
实例:
HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE);//影藏光标操作 CONSOLE_CURSOR_INFO CursorInfo;GetConsoleCursorInfo(hOutput, &CursorInfo);//获取控制台光标信息 CursorInfo.bVisible = false; //隐藏控制台光标 SetConsoleCursorInfo(hOutput, &CursorInfo);//设置控制台光标状态
SetConsoleCursorPosition
设置指定控制台屏幕缓冲区中的光标位置,我们将想要设置的坐标信息放在COORD类型的pos中,调用SetConsoleCursorPosition函数将光标位置设置到指定的位置。
BOOL WINAPI SetConsoleCursorPosition( HANDLE hConsoleOutput, COORD pos);
实例:
COORD pos = { 10, 5}; HANDLE hOutput = NULL; //获取标准输出的句柄(⽤来标识不同设备的数值) hOutput = GetStdHandle(STD_OUTPUT_HANDLE); //设置标准输出上光标的位置为pos SetConsoleCursorPosition(hOutput, pos);
SetPos:封装⼀个设置光标位置的函数
//设置光标的坐标 void SetPos(short x, short y){ COORD pos = { x, y }; HANDLE hOutput = NULL; //获取标准输出的句柄(⽤来标识不同设备的数值) hOutput = GetStdHandle(STD_OUTPUT_HANDLE);SetConsoleCursorPosition(hOutput, pos);}
GetAsyncKeyState
获取按键情况,GetAsyncKeyState的函数原型如下:
SHORT GetAsyncKeyState( int vKey);
将键盘上每个键的虚拟键值传递给函数,函数通过返回值来分辨按键的状态。
GetAsyncKeyState 的返回值是short类型,在上⼀次调⽤ GetAsyncKeyState 函数后,如果返回的16位的short数据中,最⾼位是1,说明按键的状态是按下,如果最高是0,说明按键的状态是抬 起;如果最低位被置为1则说明,该按键被按过,否则为0。 如果我们要判断⼀个键是否被按过,可以检测GetAsyncKeyState返回值的最低值是否为1。
#define KEY_PRESS(VK) ( (GetAsyncKeyState(VK) & 0x1) ? 1 : 0 )
宽字符的打印
#include <stdio.h>#include<locale.h>int main() { setlocale(LC_ALL, ""); wchar_t ch1 = L'●'; wchar_t ch2 = L'中'; wchar_t ch3 = L'国'; wchar_t ch4 = L'★'; printf("%c%c\n", 'a', 'b'); wprintf(L"%c\n", ch1); wprintf(L"%c\n", ch2); wprintf(L"%c\n", ch3); wprintf(L"%c\n", ch4); return 0;}
贪吃蛇的主要功能
贪吃蛇游戏的主要功能可以包括以下几个方面:游戏界面:游戏界面应包括蛇、食物、得分和游戏结束提示的显示,以及其他可能的游戏元素。
控制方式:提供玩家通过方向键、触屏或其他方式来控制蛇的移动方向。
单人模式:提供单人模式,玩家可以独自进行游戏。
分数统计:记录游戏分数,并在游戏结束时进行展示。
游戏结束提示:当蛇碰到边界或者自己的身体时,游戏应该结束,并给出相应的提示。
界面友好:提供简洁易懂、美观友好的游戏界面,方便玩家使用。
