按鈕ClickListener不能在LibGDX遊戲中工作

Question

我正在開發一個使用LibGDX的Android遊戲。菜單屏幕上有4個按鈕，但這些按鈕的ClickListener不起作用。

// retrieve the custom skin for our 2D widgets 
Skin skin = super.getSkin(); 

// create the table actor and add it to the stage 
table = new Table(skin); 
table.width = stage.width(); 
table.height = stage.height(); 
stage.addActor(table); 

// retrieve the table's layout 
TableLayout layout = table.getTableLayout(); 

// register the button "start game" 
TextButton startGameButton = new TextButton("Start game", skin); 
startGameButton.addListener(new ClickListener() { 
    @Override 
    public void clicked(InputEvent event, float x, float y) { 
     System.out.println("hiii"); 
     Assets.load(); 
     // game.getSoundManager().play(TyrianSound.CLICK); 
     game.setScreen(new GameScreen(game)); 
    } 
}); 

layout.register("startGameButton", startGameButton); 

如何激活LibGDX中的按鈕ClickListener？

Answer 1

您必須將按鈕添加到舞臺，並調用

Gdx.input.setInputProcessor(stage); 

Answer 2

而不是「點擊方法」，現在它的「點擊方法」（我想！），以防萬一有人面臨着同樣的問題，我是當發現這個問題時面對：

startGameButton.addListener(new ClickListener() {    
    @Override 
    public void clicked(InputEvent event, float x, float y) { 
     game.setScreen(new GameScreen(game)); 
    }; 
});
