Aircraft wars PLUS

用c语言实现打飞机的效果，子弹可以加强效果

windows平台下实现

代码如下：

game.h:

#pragma once
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <conio.h>

void HideCursor();
void gotoxy(int x, int y);
void DataInit();
void Show();
void UpdateWithoutInput();
void UpdateWithInput();

#define HIGH 15
#define WIDTH 25
#define ENEMYNUM 5

test.cpp:

#include "game.h"

int position_x, position_y;
int enemy_x[ENEMYNUM];
int enemy_y[ENEMYNUM];
int canvas[HIGH][WIDTH] = {0};
int BulletWidth;
int EnemyMoveSpeed;
int score;

int main()
{
	HideCursor();   //隐藏光标
	DataInit();     //数据初始化
	while (1)
	{
		Show();         //显示画面
		UpdateWithoutInput();     //与用户无关的数据更新
		UpdateWithInput();        //与用户有关的数据更新
	}
	return 0;
}

game.cpp:

#include "game.h"

fix.cpp:

主要用来修复画面闪屏和光标隐藏问题

可用cls函数代替实现

#include "game.h"
void HideCursor()
{
	CONSOLE_CURSOR_INFO cursor_info = { 1,0 };
	SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
}

void gotoxy(int x, int y)
{
	HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
	COORD pos;
	pos.X = x;
	pos.Y = y;
	SetConsoleCursorPosition(handle, pos);
}
