黄金矿工c语言qt代码

这是一个简单的黄金矿工游戏的 C++/Qt 代码。请注意，这只是一个基本的代码示例，需要根据您的需求进行修改和扩展。

#include <QApplication>
#include <QGraphicsScene>

    scene->setSceneRect(0, 0, 800, 600);
    setScene(scene);

    // Set the background image
    QPixmap background(":/images/background.jpg");
    scene->setBackgroundBrush(background.scaled(800, 600));

    // Create the player
    player = new QGraphicsPixmapItem(QPixmap(":/images/player.png"));
    player->setPos(400, 550);
    scene->addItem(player);

    // Set the focus to the player so we can capture key events
    player->setFlag(QGraphicsItem::ItemIsFocusable);

        }
        break;

            QGraphicsItemAnimation* animation = new QGraphicsItemAnimation;
            animation->setItem(gold);
            QPropertyAnimation* anim = new QPropertyAnimation(animation, "pos");
            anim->setDuration(2000);
            anim->setStartValue(gold->pos());
            anim->setEndValue(QPointF(gold->x(), scene->height() - gold->pixmap().height()));
            animation->setTimeLine(anim);
            anim->start(QAbstractAnimation::DeleteWhenStopped);
            break;
        }

}

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    GoldMiner game;
    return app.exec();
}

这段代码使用 Qt 框架创建了一个简单的黄金矿工游戏。游戏中的玩家可以通过左右箭头键来移动，并且需要在屏幕上收集黄金。游戏每隔 2 秒就会生成一个新的黄金项，并将其向下移动。该代码还包括一些基本的动画效果，使得收集黄金的过程看起来更加流畅。
