2.1 游戏界面
游戏主要是由三个界面构成分别是游戏大厅、难度选择和游戏内界面因此需要建立三个.cpp文件分别对应的是gamehall.cpp、gameselect.cpp和gameroom.cpp。
2.1.1 gamehall.cpp 在游戏大厅界面需要将图片设置到背景板上并且创建一个“开始游戏”按钮 GameHall::GameHall(QWidget *parent): QWidget(parent), ui(new Ui::GameHall)
{ui-setupUi(this);// 设置窗口大小、图标、名字this-setFixedSize(1080,720);this-setWindowIcon(QIcon(:Resource/icon.png));this-setWindowTitle(贪吃蛇大作战);// 设置开始按钮QFont font(华文行楷,18);QPushButton* pushButton_start new QPushButton(this);pushButton_start-setText(开始游戏);pushButton_start-setFont(font);pushButton_start-move(520,400);pushButton_start-setGeometry(440,520,160,90);pushButton_start-setStyleSheet(QPushButton{border:0px;});// 点击“开始游戏”按钮进入难度选择界面GameSelect* gameSelect new GameSelect;connect(pushButton_start,QPushButton::clicked,[](){this-close();gameSelect-setGeometry(this-geometry());gameSelect-show();QSound::play(:Resource/clicked.wav);});
}GameHall::~GameHall()
{delete ui;
}void GameHall::paintEvent(QPaintEvent *event)
{(void) *event;// 实例化画家QPainter painter(this);// 实例化绘图设备QPixmap pix(:Resource/game_hall.png);// 绘图painter.drawPixmap(0,0,this-width(),this-height(),pix);
}
2.1.2 gameselect.cpp 在游戏选择界面中同样是需要设置背景创建按钮等操作。 其中点击“简单模式”、“正常模式”、“困难模式”可以直接进入游戏房间内而查阅“历史战绩”时会弹出一个新窗口显示战绩。 GameSelect::GameSelect(QWidget *parent) : QWidget(parent)
{// 设置“难度选择”界面的图标、名字this-setFixedSize(1080,720);this-setWindowIcon(QIcon(:Resource/icon.png));this-setWindowTitle(难度选择);QFont font(华文行楷,24);GameRoom* gameRoom new GameRoom;// 设置选择难度按钮和历史战绩按钮QPushButton* pushButton_easy new QPushButton(this);pushButton_easy-move(460,160);pushButton_easy-setGeometry(460,160,150,80);pushButton_easy-setText(简单模式);pushButton_easy-setFont(font);pushButton_easy-setStyleSheet(QPushButton{border:0px;color:white});QPushButton* pushButton_normal new QPushButton(this);pushButton_normal-move(460,280);pushButton_normal-setGeometry(460,280,150,80);pushButton_normal-setText(正常模式);pushButton_normal-setFont(font);pushButton_normal-setStyleSheet(QPushButton{border:0px;color:white});QPushButton* pushButton_hard new QPushButton(this);pushButton_hard-move(460,400);pushButton_hard-setGeometry(460,400,150,80);pushButton_hard-setText(困难模式);pushButton_hard-setFont(font);pushButton_hard-setStyleSheet(QPushButton{border:0px;color:white});QPushButton* pushButton_record new QPushButton(this);pushButton_record-move(460,520);pushButton_record-setGeometry(460,520,150,80);pushButton_record-setText(历史战绩);pushButton_record-setFont(font);pushButton_record-setStyleSheet(QPushButton{border:0px;color:white});// 点击不同困难模式按钮进入游戏房间connect(pushButton_easy,QPushButton::clicked,[](){this-close();gameRoom-setGeometry(this-geometry());gameRoom-show();QSound::play(:Resource/clicked.wav);gameRoom-setTimeout(300);});connect(pushButton_normal,QPushButton::clicked,[](){this-close();gameRoom-setGeometry(this-geometry());gameRoom-show();QSound::play(:Resource/clicked.wav);gameRoom-setTimeout(200);});connect(pushButton_hard,QPushButton::clicked,[](){this-close();gameRoom-setGeometry(this-geometry());gameRoom-show();QSound::play(:Resource/clicked.wav);gameRoom-setTimeout(100);});// 设置历史战绩窗口connect(pushButton_record,QPushButton::clicked,[](){QWidget* widget new QWidget;widget-setWindowTitle(历史战绩);widget-setWindowIcon(QIcon(:Resource/icon.png));widget-setFixedSize(500,300);QSound::play(:Resource/clicked.wav);QTextEdit* edit new QTextEdit(widget);edit-setFont(font);edit-setFixedSize(500,300);QFile file(D:/bite/C-program/project/Snake/gamedata.txt);file.open(QIODevice::ReadOnly);QTextStream in(file);int data in.readLine().toInt();edit-append(历史得分为);edit-append(QString::number(data));widget-show();});
}void GameSelect::paintEvent(QPaintEvent *event)
{(void) *event;QPainter painter(this);QPixmap pix(:Resource/game_select.png);painter.drawPixmap(0,0,this-width(),this-height(),pix);
} 同时在这个界面中我们需要创建一个“回退”按钮点击可回退到游戏大厅界面 // 设置回退按钮QPushButton* pushButton_back new QPushButton(this);pushButton_back-move(1000,640);pushButton_back-setGeometry(1000,640,60,60);pushButton_back-setIcon(QIcon(:Resource/back.png));// 点击回退按钮回到上一页connect(pushButton_back,QPushButton::clicked,[](){this-close();GameHall* gameHall new GameHall;gameHall-show();QSound::play(:Resource/clicked.wav);});
2.1.3 gameroom.cpp 在游戏房间界面中我们可以看到许多元素其中不仅有“开始”、“暂停”、“退出”三个按钮还有控制小蛇移动的方向键按钮还有计分板等等元素。 我们首先要做的是设计背景以及创建各个按钮。 // 设置游戏房间大小、图标、名字this-setFixedSize(1080,720);this-setWindowIcon(QIcon(:Resource/icon.png));this-setWindowTitle(游戏房间);// 开始游戏、暂停游戏QFont font(楷体,20);QPushButton* pushButton_start new QPushButton(this);pushButton_start-move(890,460);pushButton_start-setGeometry(890,460,100,60);pushButton_start-setText(开始);pushButton_start-setFont(font);connect(pushButton_start,QPushButton::clicked,[](){isGameStart true;timer-start(moveTimeout);sound new QSound(:Resource/Trepak.wav);sound-play();sound-setLoops(-1);});QPushButton* pushButton_stop new QPushButton(this);pushButton_stop-move(890,540);pushButton_stop-setGeometry(890,540,100,60);pushButton_stop-setText(暂停);pushButton_stop-setFont(font);connect(pushButton_stop,QPushButton::clicked,[](){isGameStart false;timer-stop();sound-stop();});// 设置方向键的位置、大小、图标和快捷键QPushButton* pushButton_up new QPushButton(this);pushButton_up-move(900,220);pushButton_up-setGeometry(900,220,80,60);pushButton_up-setIcon(QIcon(:Resource/up1.png));connect(pushButton_up,QPushButton::clicked,[](){if(moveDirect ! SnakeDirect::DOWN)moveDirect SnakeDirect::UP;});pushButton_up-setShortcut(QKeySequence(Qt::Key_W));QPushButton* pushButton_down new QPushButton(this);pushButton_down-move(900,340);pushButton_down-setGeometry(900,340,80,60);pushButton_down-setIcon(QIcon(:Resource/down1.png));connect(pushButton_down,QPushButton::clicked,[](){if(moveDirect ! SnakeDirect::UP)moveDirect SnakeDirect::DOWN;});pushButton_down-setShortcut(QKeySequence(Qt::Key_S));QPushButton* pushButton_left new QPushButton(this);pushButton_left-move(820,280);pushButton_left-setGeometry(820,280,80,60);pushButton_left-setIcon(QIcon(:Resource/left1.png));connect(pushButton_left,QPushButton::clicked,[](){if(moveDirect ! SnakeDirect::RIGHT)moveDirect SnakeDirect::LEFT;});pushButton_left-setShortcut(QKeySequence(Qt::Key_A));QPushButton* pushButton_right new QPushButton(this);pushButton_right-move(980,280);pushButton_right-setGeometry(980,280,80,60);pushButton_right-setIcon(QIcon(:Resource/right1.png));connect(pushButton_right,QPushButton::clicked,[](){if(moveDirect ! SnakeDirect::LEFT)moveDirect SnakeDirect::RIGHT;});pushButton_right-setShortcut(QKeySequence(Qt::Key_D));// 设置退出按钮QPushButton* pushButton_exit new QPushButton(this);pushButton_exit-move(890,620);pushButton_exit-setGeometry(890,620,100,60);pushButton_exit-setText(退出);pushButton_exit-setFont(font);
2.2 游戏规则 蛇移动时不能碰到自己的身体否则游戏结束。每吃掉一个食物食物会随机刷新身体变长分数增加。 // 初始化贪吃蛇snakeList.push_back(QRectF(this-width() * 0.5,this-height() * 0.5,kSnakeNodeWight,kSnakeNodeHeight));moveUP();moveUP();creatFood();timer new QTimer(this);connect(timer,QTimer::timeout,[](){int count 1;if(snakeList.front().intersects(foodRect)){creatFood();count;QSound::play(:Resource/eatfood.wav);}while(count--){switch(moveDirect){case SnakeDirect::UP:moveUP();break;case SnakeDirect::DOWN:moveDOWN();break;case SnakeDirect::LEFT:moveLEFT();break;case SnakeDirect::RIGHT:moveRIGHT();break;}}snakeList.pop_back();update();});// 绘制蛇if(moveDirect SnakeDirect::UP){pix.load(:Resource/up.png);}else if(moveDirect SnakeDirect::DOWN){pix.load(:Resource/down.png);}else if(moveDirect SnakeDirect::LEFT){pix.load(:Resource/left.png);}else{pix.load(:Resource/right.png);}// 绘制蛇头、身体和尾巴auto Head snakeList.front();painter.drawPixmap(Head.x(),Head.y(),Head.width(),Head.height(),pix);pix.load(:Resource/Bd.png);for (int i 0;i snakeList.size() - 1;i){auto Body snakeList.at(i);painter.drawPixmap(Body.x(),Body.y(),Body.width(),Body.height(),pix);};auto tail snakeList.back();painter.drawPixmap(tail.x(),tail.y(),tail.width(),tail.height(),pix);// 绘制食物pix.load(:Resource/food.png);painter.drawPixmap(foodRect.x(),foodRect.y(),foodRect.width(),foodRect.height(),pix);
bool GameRoom::checkFail()
{for(int i 0;i snakeList.size();i){for(int j i 1;j snakeList.size();j){if(snakeList.at(i) snakeList.at(j)){return true;}}}return false;
}void GameRoom::creatFood()
{foodRect QRectF(qrand() % (800 / kSnakeNodeWight) * kSnakeNodeWight,qrand() % (this-height() / kSnakeNodeHeight) * kSnakeNodeHeight,kSnakeNodeWight,kSnakeNodeHeight);
}
2.3 控制方式 使用界面上的方向键上、下、左、右或者通过键盘上的快捷键W、S、A、D来控制蛇的移动方向但不能直接反向移动。 void GameRoom::moveUP()
{QPointF leftTop;QPointF rightBottom;// 蛇头auto snakeNode snakeList.front();int headX snakeNode.x();int headY snakeNode.y();// 如果穿模if(headY 20){leftTop QPointF(headX,this-height() - kSnakeNodeHeight);}else{leftTop QPointF(headX,headY - kSnakeNodeHeight);}rightBottom leftTop QPointF(kSnakeNodeWight,kSnakeNodeHeight);snakeList.push_front(QRectF(leftTop,rightBottom));
}void GameRoom::moveDOWN()
{QPointF leftTop;QPointF rightBottom;auto snakeNode snakeList.front();int headX snakeNode.x();int headY snakeNode.y();if(headY this-height()){leftTop QPointF(headX,0);}else{leftTop snakeNode.bottomLeft();}rightBottom leftTop QPointF(kSnakeNodeWight,kSnakeNodeHeight);snakeList.push_front(QRectF(leftTop,rightBottom));
}void GameRoom::moveLEFT()
{QPointF leftTop;QPointF rightBottom;auto snakeNode snakeList.front();int headX snakeNode.x();int headY snakeNode.y();if(headX 0){leftTop QPointF(800 - kSnakeNodeWight,headY);}else{leftTop QPointF(headX - kSnakeNodeWight,headY);}rightBottom leftTop QPointF(kSnakeNodeWight,kSnakeNodeHeight);snakeList.push_front(QRectF(leftTop,rightBottom));
}void GameRoom::moveRIGHT()
{QPointF leftTop;QPointF rightBottom;auto snakeNode snakeList.front();int headX snakeNode.x();int headY snakeNode.y();if(headX 760){leftTop QPointF(0,headY);}else{leftTop snakeNode.topRight();}rightBottom leftTop QPointF(kSnakeNodeWight,kSnakeNodeHeight);snakeList.push_front(QRectF(leftTop,rightBottom));
}
三、结语
这个项目比较简单通过这个项目不仅可以学习到Qt的GUI开发和事件处理技术还能熟悉C编程及基本的游戏开发概念。关于Qt中的一些基础知识我也会在后续逐步更新。
好了源码我会放在下面大家有兴趣的可以看一看欢迎大家一键三连
