Question

我现在添加了更多提示，消息框应该说不同的东西，但是它们被困在＆＃34;你前进并撞到墙上＃34;和＃34;你现在面向相反的方向＆＃34;他们什么时候不改变，我添加的第三个选项不会出现。再说一次，这是我的代码：

package game;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class game extends JFrame implements ActionListener {

JLabel prompt;
JTextField name;
JTextField name1;
JButton click;
JButton click1;
String storeName;
String storeName1;
JButton click2;


public game(){

    setLayout(null);
    setSize(300,250);
    setTitle("Text Adventure");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    prompt = new JLabel("You find yourself in a tunnel.");
    click = new JButton("Go forward!");
    click1 = new JButton("Turn around!");
    click2 = new JButton();
    name = new JTextField();
    name1 = new JTextField();
    prompt.setBounds(60,30,1300,30);
    click.setBounds(50,130,100,30);
    click.addActionListener(this);
    click1.setBounds(150,130,125,30);
    click1.addActionListener(this);
    click2.setBounds(125,160,125,30);
    click2.addActionListener(this);
    add(click);
    add(click1);
    add(name);
    add(name1);
    add(prompt);


}

public void actionPerformed(ActionEvent e) {

    if(e.getSource() == click) {

        JOptionPane.showMessageDialog(null, "You go forward and hit a wall.");
    }
    {
    if(e.getSource() == click1) {

        JOptionPane.showMessageDialog(null, "You are now facing the opposite direction.");
        prompt.setText("What would you like to do now?");
        click.setText("Go forward!");
        click1.setText("Turn on light.");

    }
    }
}

public void actionPerformed1(ActionEvent e) {

    if(e.getSource() == click) {

        JOptionPane.showMessageDialog(null, "You walk down the tunnel until you hit an intersection.");
        prompt.setText("Which way would you like to go?");
        click.setText("Left!");
        click1.setText("Right!");
        add(click2);
        click2.setText("Keep going!");
    }

    if(e.getSource() == click1) {

    }
}

public static void main(String args[]){

    game s = new game();
    s.setVisible(true);
    }
}

Answer 1

在actionPerformed功能中，使用

prompt.setText(" new prompt");

将提示设置为另一个提示。

您也可以使用以下选项更改选项：

click.setText(" new click command");
click1.setText(" new click1 command");

我试图用Java制作基于文本的GUI游戏。如何更新消息框以显示下一个结果？
