【推荐福利】c++使用easyx做出像素鸟，简单上手小游戏

老规矩，先上效果图\
\
1首先加载一堆资源图片

// 加载图片资源
void loadRes()
{
    loadimage(&BK[0], _T("res\\bg_day.png"));
    loadimage(&BK[1], _T("res\\bg_night.png"));

    loadimage(&bk, _T("res\\bg_day.png"));

    loadimage(&OVEIMG, _T("res\\bg_day.png"));

    loadimage(&BIRD[0][0], _T("res\\bird0_0.png"));
    loadimage(&BIRD[0][1], _T("res\\bird0_1.png"));
    loadimage(&BIRD[0][2], _T("res\\bird0_2.png"));
    loadimage(&BIRD[1][0], _T("res\\bird1_0.png"));
    loadimage(&BIRD[1][1], _T("res\\bird1_1.png"));
    loadimage(&BIRD[1][2], _T("res\\bird1_2.png"));
    loadimage(&BIRD[2][0], _T("res\\bird2_0.png"));
    loadimage(&BIRD[2][1], _T("res\\bird2_1.png"));
    loadimage(&BIRD[2][2], _T("res\\bird2_2.png"));

    loadimage(&PIPE[0][0], _T("res\\pipe_down.png"));
    loadimage(&PIPE[0][1], _T("res\\pipe_up.png"));
    loadimage(&PIPE[1][0], _T("res\\pipe2_down.png"));
    loadimage(&PIPE[1][1], _T("res\\pipe2_up.png"));

    loadimage(&NUMBER[0][0], _T("res\\font_048.png"));
    loadimage(&NUMBER[0][1], _T("res\\font_049.png"));
    loadimage(&NUMBER[0][2], _T("res\\font_050.png"));
    loadimage(&NUMBER[0][3], _T("res\\font_051.png"));
    loadimage(&NUMBER[0][4], _T("res\\font_052.png"));
    loadimage(&NUMBER[0][5], _T("res\\font_053.png"));
    loadimage(&NUMBER[0][6], _T("res\\font_054.png"));
    loadimage(&NUMBER[0][7], _T("res\\font_055.png"));
    loadimage(&NUMBER[0][8], _T("res\\font_056.png"));
    loadimage(&NUMBER[0][9], _T("res\\font_057.png"));

    loadimage(&NUMBER[1][0], _T("res\\number_context_00.png"));
    loadimage(&NUMBER[1][1], _T("res\\number_context_01.png"));
    loadimage(&NUMBER[1][2], _T("res\\number_context_02.png"));
    loadimage(&NUMBER[1][3], _T("res\\number_context_03.png"));
    loadimage(&NUMBER[1][4], _T("res\\number_context_04.png"));
    loadimage(&NUMBER[1][5], _T("res\\number_context_05.png"));
    loadimage(&NUMBER[1][6], _T("res\\number_context_06.png"));
    loadimage(&NUMBER[1][7], _T("res\\number_context_07.png"));
}

2 初始化游戏资源

void init()
{
    // 加载图形资源
    loadRes();
    // 初始化图形界面
    initgraph(288, 512);
    // 初始化随机数种子
    srand((unsigned int)time(NULL));
    // 初始化变量
    best = 0;
    isDay = rand() % 2;
    birdColor = rand() % 3;
    // 游戏初始时间
    clock_t time = clock();
    // 开场动画
    while (true)
    {
        reset();
        drawAlpha(&bk, 60, 120, &TITLE);
        drawAlpha(&bk, 125, 200, &BIRD[birdColor][pose]);
        drawAlpha(&bk, 90, 270, &PLAY);
        pose = ((clock() - time) / diff) % 3;
        put();
        if (GetControl())
        {
            break;
        }
        Sleep(10);
    }
}

3开始游戏

// 游戏预处理
void start()
{
    // 初始化数据
    isDay = rand() % 2;
    birdColor = rand() % 3;
    pipeX[0] = 288 + 30;
    pipeX[1] = 288 + 30 + 190;
    pipeY[0] = rand() % 250;
    pipeY[1] = rand() % 250;
    pose = 0;
    landX = 0;
    score = 0;
    y = 220;
    vy = 0;

    // 游戏初始时间
    clock_t time = clock();
    // 开场动画
    clock_t t = clock();
    while (true)
    {
        reset();
        drawScore(60, score, 13, 26, 144, 0);
        drawAlpha(&bk, 50, 120, &READY);
        drawAlpha(&bk, (int)x, (int)y, &BIRD[birdColor][pose]);
        drawAlpha(&bk, 90, 220, &TUTORIAL);
        drawAlpha(&bk, (int)landX, (int)landY, &LAND);
        landX -= (clock() - t) * vx / 100;
        t = clock();
        pose = ((clock() - time) / diff) % 3;
        put();
        if (landX < -44)
        {
            landX = -20;
        }
        if (GetControl())
        {
            break;
        }
        Sleep(10);
    }
}

4操控像素鸟

bool GetControl() 
{
    bool res = false;

    if (_kbhit()) 
    {
        char ch = _getch();
        if (ch == ' ') 
        {
            res = true;
        }
    }

    MOUSEMSG msg;
    while (MouseHit()) 
    {
        msg = GetMouseMsg();
        if (msg.mkLButton) 
        {
            res = true;
        }
    }

    return res;
}

这里面操控比较简单，就是鼠标单机/按下空格键，像素鸟都会弹一下。

5鸟死亡，判断gameover的逻辑

// 判断鸟死亡
bool isDie()
{
    if (y + buttom > landY)
        return true;

    if (x + right > pipeX[0] && x + left < pipeX[0] + 52)
    {
        if (y + top < pipeY[0] + 40 || y + buttom > pipeY[0] + 140)
            return true;
    }

    if (x + right > pipeX[1] && x + left < pipeX[1] + 52)
    {
        if (y + top < pipeY[1] + 40 || y + buttom > pipeY[1] + 140)
            return true;
    }

    return false;
}
