可以用C++写一个射击游戏吗

可以的，下面是一个简单的 C++ 射击游戏示例。这个示例中，玩家需要操作键盘控制一个小飞机射击从上往下掉落的敌机，每击落一个敌机得到一分，直到游戏结束。

#include <iostream>
#include <conio.h>
#include <windows.h>
using namespace std;

const int WIDTH = 30; // 游戏界面宽度
const int HEIGHT = 20; // 游戏界面高度
const int MAX_ENEMIES = 20; // 最大敌机数量
const int SHOOT_DELAY = 3; // 射击延迟
const int ENEMY_DELAY = 10; // 敌机创建延迟

void gotoxy(int x, int y) // 移动光标到指定位置
{
    COORD coord = { x, y };
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

class Enemy // 敌机类
{
public:
    int x, y;
    bool active;
    Enemy() { active = false; }
    void move() { y++; }
    void draw() { gotoxy(x, y); cout << "V"; }
    void clear() { gotoxy(x, y); cout << " "; }
};

class Player // 玩家类
{
public:
    int x, y, score;
    bool active;
    int shootDelay; // 射击延迟
    Player() { x = WIDTH / 2; y = HEIGHT - 1; score = 0; active = true; shootDelay = 0; }
    void move(int dx) { x += dx; if (x < 0) x = 0; if (x >= WIDTH) x = WIDTH - 1; }
    void shoot();
    void draw() { gotoxy(x, y); cout << "^"; }
    void clear() { gotoxy(x, y); cout << " "; }
};

void Player::shoot() // 玩家射击
{
    if (shootDelay > 0) return;
    shootDelay = SHOOT_DELAY;
    gotoxy(x, y - 1); cout << "*";
}

int main()
{
    srand(time(NULL));
    Player player;
    Enemy enemies[MAX_ENEMIES];
    int enemyDelay = ENEMY_DELAY;
    while (true)
    {
        if (_kbhit()) // 处理键盘输入
        {
            char ch = _getch();
            if (ch == 'a') player.move(-1);
            if (ch == 'd') player.move(1);
            if (ch == ' ') player.shoot();
        }
        if (player.shootDelay > 0) player.shootDelay--;
        if (enemyDelay > 0) enemyDelay--;
        else // 创建新敌机
        {
            for (int i = 0; i < MAX_ENEMIES; i++)
            {
                if (!enemies[i].active)
                {
                    enemies[i].x = rand() % WIDTH;
                    enemies[i].y = 0;
                    enemies[i].active = true;
                    break;
                }
            }
            enemyDelay = ENEMY_DELAY;
        }
        system("cls"); // 清屏
        for (int i = 0; i < MAX_ENEMIES; i++) // 移动和绘制敌机
        {
            if (enemies[i].active)
            {
                enemies[i].clear();
                enemies[i].move();
                enemies[i].draw();
                if (enemies[i].y >= HEIGHT) // 敌机超出屏幕
                {
                    enemies[i].clear();
                    enemies[i].active = false;
                }
                else if (enemies[i].x == player.x && enemies[i].y == player.y) // 玩家被撞
                {
                    player.active = false;
                }
            }
        }
        if (player.active) // 绘制玩家
        {
            player.clear();
            player.draw();
        }
        else // 游戏结束
        {
            gotoxy(WIDTH / 2 - 4, HEIGHT / 2);
            cout << "Game Over!";
            gotoxy(WIDTH / 2 - 4, HEIGHT / 2 + 1);
            cout << "Score: " << player.score;
            break;
        }
        for (int i = 0; i < MAX_ENEMIES; i++) // 处理玩家的射击
        {
            if (enemies[i].active)
            {
                for (int j = 0; j < SHOOT_DELAY; j++)
                {
                    if (player.active && player.x == enemies[i].x && player.y - j == enemies[i].y)
                    {
                        enemies[i].clear();
                        enemies[i].active = false;
                        player.score++;
                        break;
                    }
                }
            }
        }
        Sleep(30); // 延迟一段时间
    }
    return 0;
}

这只是一个简单的示例，你可以根据自己的需求进行修改和扩展。
