Question

当我设置事件Mouse_Clicked时，它应该返回主菜单，但是当我点击鼠标时什么都不做。我希望它转到MENUSTATE这是主菜单，但没有任何反应。我需要帮助，因为这是一个学校项目，我不知道出了什么问题。

package GameState;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics2D;
import java.awt.event.MouseEvent;
import main.GamePanel;

public class HelpState extends GameState {
    private Color titleColor;
    private Font titleFont;

    public HelpState(GameStateManager gameStateManager) {
        init();
    }

    @Override
    public void init() { }

    @Override
    public void update() {
        // TODO Auto-generated method stub
    }

    @Override
    public void draw(Graphics2D g) {
        g.setColor(titleColor);
        g.setFont(titleFont);

        g.clearRect(1, 1, GamePanel.WIDTH, GamePanel.HEIGHT);
        g.drawString("Move Left: Left Arrow ", 0, 25);
        g.drawString("Move Right: Right Arrow ", 0, 45);
        g.drawString("Attack: A Button ", 0, 65); 
        g.drawString("Become Other Wumps: You must have things happened to", 0, 85);
        g.drawString("you (Eg. Get smashed by a wall). After that you must press ", 0, 95);
        g.drawString("the corresponding No. Key.", 0, 105);
    }

    private void select() {
        gsm.setState(GameStateManager.MENUSTATE);
    }

    public void mousePressed(int m) {
        if (m == MouseEvent.MOUSE_CLICKED) {
            select();
        }
    }

    @Override
    public void keyReleased(int k) {
        // TODO Auto-generated method stub
    }

    @Override
    public void keyPressed(int k) {
        // TODO Auto-generated method stub
    }
}

您应该实现MouseListener以从鼠标获取输入。

如果要检查按钮是否按下，我建议您使用ActionListener。如果您需要额外的属性，请单击使用MouseListener。

示例MouseListener：

 import java.awt.event.MouseListener;

 public void mousePressed(MouseEvent e) {
       saySomething("Mouse pressed position "
                    + e.getPoint(), e);
    }

Java GameState没有改变
