c＋＋，qt中我显示了一个英雄和一些怪物，怎么实现怪物追踪英雄呢?

#include <QApplication>
#include <QMainWindow>
#include <QHBoxLayout>
#include <QLabel>
#include <QPushButton>
#include <QTextEdit>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QMainWindowMainWindow window;
    window.setWindowTitle("英雄和怪兽追踪");

    QHBoxLayout *layout = new QHBoxLayout;
    QLabel *label = new QLabel("请输入英雄的位置:");
    QPushButton *button = new QPushButton("确定");
    layout->addWidget(label);
    layout->addWidget(button);

    QTextEdit *text = new QTextEdit;
    text->setText("怪兽的位置:");
    layout->addWidget(text);

    QHBoxLayout *layout2 = new QHBoxLayout;
    QLabel *label2 = new QLabel("请输入怪兽的速度:");
    QPushButton *button2 = new QPushButton("确定");
    layout2->addWidget(label2);
    layout2->addWidget(button2);
    layout2->addWidget(text);

    QLabel *label3 = new QLabel("请输入英雄的速度:");
    QPushButton *button3 = new QPushButton("确定");
    layout2->addWidget(label3);
    layout2->addWidget(button3);

    layout->addLayout(layout2);

    text->setText("怪兽的位置:");
    button->setText("确定");
    button->setButtonText("重置");

    QMainWindowMainWindow(&window);
    window.show();

    return app.exec();
}
