Question

我目前正在使用Java中的Slick2D开发一个简单的多人游戏。菜单结构会有点复杂，因为我需要几个文本字段来获取连接服务器地址的信息，允许播放的玩家数量，昵称等等。

我在3个课程中重现了我的问题：主要课程（ExampleGame）来自StateBasedGame的{{1}}，Play和Menu。

班级BasicGameState和Play分别有一个文字字段和一个按钮。我的问题是我只能将其中一个类输入到文本字段中。单击文本字段时，另一个文本字段不显示任何光标响应。

这是主要的类ExampleGame：

Menu

}

ExampleGame自动调用MainMenu（Menu.java）：

public class ExampleGame extends StateBasedGame  {

public static final int MAIN_MENU_STATE = 0;
public static final int GAME_PLAY_STATE = 1;

public ExampleGame(String name) {
    super(name);

    this.addState(new Menu(MAIN_MENU_STATE));
this.addState(new Play(GAME_PLAY_STATE));

this.enterState(MAIN_MENU_STATE);
}

/**
 * @param args
 */
public static void main(String[] args) {
     AppGameContainer appgc;
 try{
    appgc = new AppGameContainer(new ExampleGame("ExampleGame"));
    appgc.setDisplayMode(640, 360, false);
    appgc.setTargetFrameRate(50);
    appgc.start();
 }catch(SlickException e){
    e.printStackTrace();
 }
}

@Override
public void initStatesList(GameContainer arg0) throws SlickException {
    // TODO Auto-generated method stub
    this.getState(GAME_PLAY_STATE);
    this.getState(MAIN_MENU_STATE);


System.out.println(this.getStateCount() + ", " + this.getCurrentStateID());
this.enterState(MAIN_MENU_STATE);
}

}

我可以在这里写一下文字字段。到现在为止还挺好。通过单击按钮，我调用下一页（Play.java）：

public class Menu extends BasicGameState {

private int stateID;
private Image background;
private UnicodeFont font;
private TextField textfield;
private Image createGameOption;
private int menuX = 50;
private int menuY = 250;


public Menu(int stateID) {
    this.stateID = stateID;
}


@Override
public void init(GameContainer arg0, StateBasedGame arg1) throws SlickException {

    System.out.println("StateID: " + arg1.getState(this.getID()) + " , State: " + arg1.getCurrentState());

    background = new Image("images/background_1024x640_v1.jpg");
    createGameOption = new Image("images/btn_CreateGame_for_1024x640_v1.png");

    textfield = new TextField(arg0, arg0.getDefaultFont(), 100, 100, 200, 30);
}


@Override
public void render(GameContainer arg0, StateBasedGame arg1, Graphics arg2) throws SlickException {
    // TODO Auto-generated method stub
    background.draw(0, 0);
    createGameOption.draw(menuX, menuY);
    textfield.render(arg0, arg2);

}


@Override
public void update(GameContainer arg0, StateBasedGame arg1, int arg2) throws SlickException {

    Input input = arg0.getInput();

    int mouseX = input.getMouseX();
    int mouseY = input.getMouseY();

    // if mouse is over a button
    if ((mouseX >= menuX && mouseX <= menuX + createGameOption.getWidth()) && (mouseY >= menuY && mouseY <= menuY + createGameOption.getHeight())) {

        if (input.isMouseButtonDown(Input.MOUSE_LEFT_BUTTON)) {
            // fx.play();
            arg1.enterState(ExampleGame.GAME_PLAY_STATE);
        }

    }

}


@Override
public int getID() {
    // TODO Auto-generated method stub
    return stateID;
}

}

类public class Play extends BasicGameState { private int stateID; private Image background; private UnicodeFont font; private TextField textfield; private Image createGameOption; private int menuX = 350; private int menuY = 250; public Play (int stateID) { this.stateID = stateID; } @Override public void init(GameContainer arg0, StateBasedGame arg1) throws SlickException { System.out.println("StateID: " + arg1.getCurrentStateID() + " , State: " + arg1.getCurrentState()); arg1.inputStarted(); background = new Image("images/background_1024x640_v1.jpg"); createGameOption = new Image("images/btn_CreateGame_for_1024x640_v1.png"); textfield = new TextField(arg0, arg0.getDefaultFont(), 150, 100, 200, 30); } @Override public void render(GameContainer arg0, StateBasedGame arg1, Graphics arg2) throws SlickException { // TODO Auto-generated method stub background.draw(0,0); createGameOption.draw(menuX, menuY); textfield.render(arg0, arg2); } @Override public void update(GameContainer arg0, StateBasedGame arg1, int arg2) throws SlickException { Input input = arg0.getInput(); int mouseX = input.getMouseX(); int mouseY = input.getMouseY(); if ((mouseX >= menuX && mouseX <= menuX + createGameOption.getWidth()) && (mouseY >= menuY && mouseY <= menuY + createGameOption.getHeight())) { if (input.isMouseButtonDown(Input.MOUSE_LEFT_BUTTON)) { arg1.enterState(ExampleGame.MAIN_MENU_STATE); } } } @Override public int getID() { // TODO Auto-generated method stub return stateID; }与Play的代码几乎相同，但似乎Menu中的文本字段不响应鼠标和键。它似乎处于非活动状态，因为您无法看到任何更改。但事实并非如此。如果我在文本字段中单击，键入内容并通过单击按钮返回菜单，您可以看到您输入的文本。似乎两个文本字段（来自菜单和来自Play的文本字段）都连接到不知何故。但我不知道问题出在哪里。

有没有人建议我如何解决这个问题？

提前致谢！
