要在QT中实现剪刀石头布游戏，你可以使用QWidget和QPushButton等控件，以及QMessageBox来显示游戏结果。以下是一个简单的示例代码：
#include <QApplication>
#include <QWidget>
#include <QPushButton>
#include <QGridLayout>
#include <QMessageBox>
#include <QRandomGenerator>
class RockPaperScissorsWidget : public QWidget
{
Q_OBJECT
public:
explicit RockPaperScissorsWidget(QWidget *parent = nullptr) : QWidget(parent)
{
QGridLayout* layout = new QGridLayout(this);
rockButton = new QPushButton("Rock", this);
layout->addWidget(rockButton, 0, 0);
paperButton = new QPushButton("Paper", this);
layout->addWidget(paperButton, 0, 1);
scissorsButton = new QPushButton("Scissors", this);
layout->addWidget(scissorsButton, 0, 2);
connect(rockButton, &QPushButton::clicked, this, &RockPaperScissorsWidget::playGame);
connect(paperButton, &QPushButton::clicked, this, &RockPaperScissorsWidget::playGame);
connect(scissorsButton, &QPushButton::clicked, this, &RockPaperScissorsWidget::playGame);
setLayout(layout);
}
private slots:
void playGame()
{
QObject* sender = QObject::sender();
if (sender == rockButton) {
playerChoice = Choice::Rock;
computerChoice = getRandomChoice();
} else if (sender == paperButton) {
playerChoice = Choice::Paper;
computerChoice = getRandomChoice();
} else if (sender == scissorsButton) {
playerChoice = Choice::Scissors;
computerChoice = getRandomChoice();
}
showResult();
}
private:
enum class Choice
{
Rock,
Paper,
Scissors
};
Choice playerChoice;
Choice computerChoice;
QPushButton* rockButton;
QPushButton* paperButton;
QPushButton* scissorsButton;
Choice getRandomChoice()
{
int choice = QRandomGenerator::global()->bounded(3);
return static_cast<Choice>(choice);
}
void showResult()
{
QString resultText;
if (playerChoice == computerChoice) {
resultText = "It's a tie!";
} else if ((playerChoice == Choice::Rock && computerChoice == Choice::Scissors) ||
(playerChoice == Choice::Paper && computerChoice == Choice::Rock) ||
(playerChoice == Choice::Scissors && computerChoice == Choice::Paper)) {
resultText = "You win!";
} else {
resultText = "Computer wins!";
}
QMessageBox::information(this, "Result", resultText);
}
};
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
RockPaperScissorsWidget rockPaperScissorsWidget;
rockPaperScissorsWidget.setWindowTitle("Rock Paper Scissors");
rockPaperScissorsWidget.show();
return app.exec();
}
#include "main.moc"
在示例代码中，我们创建了一个RockPaperScissorsWidget类，继承自QWidget，它代表了剪刀石头布游戏的界面。界面中有三个按钮，分别对应剪刀、石头和布。
当玩家点击其中一个按钮时，相关的槽函数playGame会被调用。槽函数根据玩家的选择获取电脑的随机选择，然后调用showResult函数来显示游戏结果。
在showResult函数中，根据玩家和电脑的选择判断游戏结果，并通过QMessageBox显示对话框来展示结果。
在main函数中，创建RockPaperScissorsWidget实例，并运行应用程序。
你可以根据需要进行扩展和美化，比如添加计分功能、显示当前玩家选择等。同时，你也可以根据自己的设计进行界面和交互上的修改。
