Question

我有一个游戏代码，可以构建一个框架并将其设置为可见和内容，并将contentPane设置为我创建的GamePanel类。这会创建一个gamestatemanager，然后从状态0或菜单状态开始。这是Menu State类的代码。持续发生的事情是在显示菜单之前，会弹出一个弹出框，该弹出框是选择编号1的init()的一部分，就像使用回车键和select()方法选择它一样，我没有能够找出原因。

编辑：我已经强制了一些错误让控制台按顺序给我方法调用，并且它说它正在初始化GameStateManager，在它将DiceGameState（this）添加到ArrayList的行中它正在初始化DiceGameState，这是问题所在。谢谢你的帮助。

MenuState.java：

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics2D;
import java.awt.event.KeyEvent;

public class MenuState extends GameState {

private Background bg;

private int choice = 0;
private String[] options = { "Slot Machine", "Dice Toss", "Roulette Wheel", "Stats", "Leaderboards", "Quit" };

private Color titleColor;
private Font titleFont;

private Font font;

public MenuState(GameStateManager gsm) {
    this.gsm = gsm;
    try {
        bg = new Background("/Backgrounds/menubg.png", 1);
        bg.setVector(-0.1, 0);

        titleColor = Color.BLACK;
        titleFont = new Font("Georgia", Font.PLAIN, 28);
    } catch (Exception e) {
        e.printStackTrace();
    }

    font = new Font("Arial", Font.PLAIN, 12);
}

@Override
public void init() {
}

@Override
public void update() {
    bg.update();
}

@Override
public void draw(Graphics2D g) {
    // Draw BG
    bg.draw(g);

    // Draw title
    g.setColor(titleColor);
    g.setFont(titleFont);
    g.drawString("Jolly Jackpot Land!", 36, 60);

    g.setFont(font);
    for (int i = 0; i < options.length; i++) {
        if (i == choice)
            g.setColor(Color.RED);
        else
            g.setColor(Color.WHITE);
        g.drawString(options[i], 40, 130 + i * 15);
    }
    g.setColor(Color.WHITE);
    g.setFont(new Font("Arial", Font.PLAIN, 10));
    g.drawString("v1.0.2.24.16 (c) Matthew Young", 165, 235);
}

private void select() {
    if (choice == 0) {
        // Slots
        gsm.setState(GameStateManager.SLOTGAMESTATE);
    }
    if (choice == 1) {
        // Dice
        gsm.setState(GameStateManager.DICEGAMESTATE);
    }
    if (choice == 2) {
        gsm.setState(GameStateManager.ROULETTEGAMESTATE);
    }
    if (choice == 3) {
        gsm.setState(GameStateManager.STATSTATE);
    }
    if (choice == 4) {
        gsm.setState(GameStateManager.HELPSTATE);
    }
    if (choice == 5) {
        System.exit(0);
    }
}

@Override
public void keyPressed(int k) {
    if (k == KeyEvent.VK_ENTER) {
        select();
    }
    if (k == KeyEvent.VK_UP) {
        choice--;
        if (choice == -1) {
            choice = options.length - 1;
        }
    }
    if (k == KeyEvent.VK_DOWN) {
        choice++;
        if (choice == options.length) {
            choice = 0;
        }
    }
}

@Override
public void keyReleased(int k) {
}
}

GameStateManager.java

import java.util.ArrayList;

public class GameStateManager {


private ArrayList<GameState> gameStates;
private int currentState;

public static final int MENUSTATE = 0;
public static final int SLOTGAMESTATE = 1;
public static final int DICEGAMESTATE = 2;
public static final int ROULETTEGAMESTATE = 3;
public static final int STATSTATE = 4;
public static final int HELPSTATE = 5;

public GameStateManager() {
    gameStates = new ArrayList<GameState>();

    currentState = 0;
    gameStates.add(new MenuState(this));
    gameStates.add(new SlotGameState(this));
    gameStates.add(new DiceGameState(this));
    gameStates.add(new RouletteGameState(this));
    gameStates.add(new HelpState(this));
}

public void setState(int state){
    currentState = state;
    gameStates.get(currentState).init();
    currentState = 0;
}

public int getState() {
    return currentState;
}

public void update() {
    gameStates.get(currentState).init();
}

public void draw(java.awt.Graphics2D g){
    gameStates.get(currentState).draw(g);
}

public void keyPressed(int k){
    gameStates.get(currentState).keyPressed(k);
}

public void keyReleased(int k) {
    gameStates.get(currentState).keyReleased(k);
}
}

为什么我的方法独立运行？
