【问题描述】：

所以我对这个网站以及使用 c++ 和 allegro 编程有点陌生，但是我在制作的这个游戏中一直遇到这个问题，我似乎无法弄清楚.这似乎不是数组溢出（我最初是这么想的），所以如果有人知道问题出在哪里，我会很高兴。

代码很长，抱歉。我真的不知道我在做什么。我遗漏了一些内容，所以希望这不会影响任何事情。

提前致谢。

    BITMAP* buffer = create_bitmap(screen->w,screen->h);

    initialization(x_enemy, y_enemy, x, y, e_color, hit, color, buffer); // begins the game, inculding initializing player and enemies

    game_play(x_enemy, y_enemy, x, y, e_color, hit, color, over, buffer); // plays the game

    end_message(x_enemy, y_enemy, x, y, e_color, hit, color, over, buffer); // ends the game

// the enemies intial spot
void initialize_enemy(int x[9], int y[9], int color[9], bool hit[9]) 

    //seed the random number generator
    srand((unsigned)time(0));

    for(int a = 0 ; a < 10 ; a++)
    
        hit[a] = false;
        x[a] = rand()%620;
        y[a] = rand()%460;
        color[a] = 0x00FF0000;
    

【参考方案1】：

首先，如果你初始化一个有 9 个插槽的数组，你只能在 0-8 范围内使用它们（总共 9 个）

void initialize_enemy(int x[9], int y[9], int color[9], bool hit[9]) 

//seed the random number generator
srand((unsigned)time(0));

    for(int a = 0 ; a < 9 ; a++) // The array size of every variable is not big enough
                                // So I changed it accordingly to 9 from 10
        hit[a] = false;
        x[a] = rand()%620;
        y[a] = rand()%460;
        color[a] = 0x00FF0000;
    

您遗漏了代码中 50% 的重要部分，我认为您在任何地方都犯了这个错误，但您可以搜索所有代码并轻松解决问题。
