飞机躲避障碍物的源代码

好的，这里提供一个简单的飞机躲避障碍物游戏的源代码示例。这个游戏中，玩家需要控制飞机躲避随机生成的障碍物，当飞机碰到障碍物时游戏结束。代码注释中会解释每个函数和变量的用途。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <stdbool.h>
#include <conio.h>

typedef struct {
    int x, y;

    COORD pos = { x, y };
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

int rand_range(int min, int max) {
    return min + rand() % (max - min + 1);
}

void draw_char(char ch, int x, int y) {
    gotoxy(x, y);
    putchar(ch);
}

    for (int i = 0; i < h; i++) {
        for (int j = 0; j < w; j++) {
            draw_char('#', x + j, y + i);
        }
    }
}

void draw_player(Player player) {
    draw_char('^', player.position.x, player.position.y);

    return false;
}

int main() {
    srand(time(NULL));
    Player player = { { SCREEN_WIDTH / 2, SCREEN_HEIGHT - 1 }, 3 };
    Obstacle obstacles[OBSTACLE_COUNT];

    for (int i = 0; i < OBSTACLE_COUNT; i++) {
        obstacles[i].position.x = rand_range(0, SCREEN_WIDTH - 10);
        obstacles[i].position.y = rand_range(0, SCREEN_HEIGHT - 10);
        obstacles[i].width = rand_range(5, 10);
        obstacles[i].height = rand_range(5, 10);
    }

    int score = 0;
    bool game_over = false;

    while (!game_over) {
        // 读取输入
        if (_kbhit()) {
            char ch = _getch();
            if (ch == 'a') {
                update_player(&player, -1, 0);
            } else if (ch == 'd') {
                update_player(&player, 1, 0);
            }
        }

        // 更新障碍物位置
        for (int i = 0; i < OBSTACLE_COUNT; i++) {
            update_obstacle(&obstacles[i], 0, 1);
            if (obstacles[i].position.y >= SCREEN_HEIGHT) {
                obstacles[i].position.y = 0;
                obstacles[i].position.x = rand_range(0, SCREEN_WIDTH - obstacles[i].width);
            }

            // 检测碰撞
            if (check_collision(player, obstacles[i])) {
                player.lives--;
                if (player.lives == 0) {
                    game_over = true;
                }
                score = 0;
                break;
            }
        }

        // 更新分数
        score++;

        // 绘制游戏界面
        system("cls");
        for (int i = 0; i < OBSTACLE_COUNT; i++) {
            draw_obstacle(obstacles[i]);
        }
        draw_player(player);
        printf("Score: %d\nLives: %d\n", score, player.lives);
        Sleep(50);
    }

    // 游戏结束
    system("cls");
    printf("Game over!\nFinal score: %d\n", score);
    return 0;
}

这个代码示例中，我们使用了 Windows 平台下的 conio.h 头文件和 Sleep 函数来控制游戏帧率和输入读取。如果你使用的是其他平台，可能需要使用不同的方法来实现同样的功能。同时，这个代码示例中的游戏逻辑和界面都比较简单，你可以根据自己的需求进行修改和扩展。
