Libgdx在游戏中弹出屏幕与输入处理器冲突

Question

在我的LibGdx游戏中，我想在游戏屏幕中创建一个暂停按钮。为此，我创建了一个这样的舞台对象。

Stage stage; 
stage = new Stage(game.viewPort); 

我想有这样的说法：

Gdx.input.setInputProcessor(stage); 

但另一种说法是已经存在;

Gdx.input.setInputProcessor(inputmultiplexer); 

因此，当我添加一个暂停按钮，它显示出来，但按钮的侦听器似乎不工作。

private void drawPauseButton() { 

    pauseButton = new ImageButton(new TextureRegionDrawable(pauseTexture), 
      new TextureRegionDrawable(pausePressTexture)); 
    stage.addActor(pauseButton); 

    pauseButton.setPosition(Constants.WORLD_WIDTH,30, Align.bottomRight); 

    pauseButton.addListener(new ActorGestureListener() { 
     @Override 
     public void tap(InputEvent event, float x, float y, int count, int button) { 
      super.tap(event, x, y, count, button); 
      game.setScreen(new PauseScreen(game)); 

      // dispose(); 
     } 
    }); 
} 

如何解决此问题？

输入多路码：

public class MyInputProcessor implements InputProcessor,GestureListener { 

public static boolean isTouchDown=false; 
public static boolean isTouchUp=false; 
public static boolean isTap=false; 
public static boolean isLongPress=false; 
public static boolean isFling=false; 
public static boolean isSwipeDown=false; 
public static boolean isSwipeUp=false; 
public static boolean isSwipeLeft=false; 
public static boolean isSwipeRight=false; 
public static boolean isKeyDown=false; 

public static boolean isZoomed=false; 
public static float zoomInitDist=0; 
public static float zoomDist=0; 


public MyInputProcessor() { 
    // TODO Auto-generated constructor stub 
    System.out.println("My Input Processor Created..");  
} 

public InputMultiplexer returnInput() { 
    // TODO Auto-generated method stub 
     InputMultiplexer im = new InputMultiplexer(); 
     GestureDetector gd = new GestureDetector(this); 
     im.addProcessor(gd); 
     im.addProcessor(this); 

    return im; 
} 


@Override 
public boolean tap(float x, float y, int count, int button) { 
    // TODO Auto-generated method stub 

    return false; 
} 

@Override 
public boolean longPress(float x, float y) { 
    // TODO Auto-generated method stub 
    this.isLongPress=true; 
    return false; 
} 

@Override 
public boolean fling(float velocityX, float velocityY, int button) { 
    // TODO Auto-generated method stub 
    if(Math.abs(velocityX)>Math.abs(velocityY)){ 
     if(velocityX>0){ 
       this.isSwipeRight=true; 
     }else{ 
      this.isSwipeLeft=true; 
     } 
    }else{ 
     if(velocityY>0){ 
      this.isSwipeDown=true; 
     }else{         
       this.isSwipeUp=true; 
     } 
    } 
    return false; 
} 

@Override 
public boolean pan(float x, float y, float deltaX, float deltaY) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean panStop(float x, float y, int pointer, int button) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean zoom(float initialDistance, float distance) { 
    // TODO Auto-generated method stub 
    this.isZoomed=true; 
    this.zoomInitDist=initialDistance; 
    this.zoomDist=distance; 
    return false; 
} 

@Override 
public boolean pinch(Vector2 initialPointer1, Vector2 initialPointer2, Vector2 pointer1, Vector2 pointer2) { 
    // TODO Auto-generated method stub 
    return false; 
} 

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

} 

@Override 
public boolean keyDown(int keycode) { 
    // TODO Auto-generated method stub 
    this.isKeyDown=true; 
    return true; 
} 

@Override 
public boolean keyUp(int keycode) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean keyTyped(char character) { 
    // TODO Auto-generated method stub 
    return false; 
} 



@Override 
public boolean mouseMoved(int screenX, int screenY) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean scrolled(int amount) { 
    // TODO Auto-generated method stub 
    return false; 
} 


@Override 
public boolean touchDown(int screenX, int screenY, int pointer, int button) { 

    MyInputProcessor.isTouchDown=true; 
    return false; 
} 

@Override 
public boolean touchUp(int screenX, int screenY, int pointer, int button) { 

     MyInputProcessor.isTouchUp=true; 
     return false; 
} 

@Override 
public boolean touchDragged(int screenX, int screenY, int pointer) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean touchDown(float x, float y, int pointer, int button) { 
    // TODO Auto-generated method stub 
    return false; 
} 

里面gamescreen类的显示方法：

MyInputProcessor myInputProcessor = new MyInputProcessor(); 
    InputMultiplexer im = myInputProcessor.returnInput(); 
    Gdx.input.setInputProcessor(im); 

Answer 1

的InputProcessor委托给其他InputProcessors的有序列表。如果处理器返回true，则表示事件已被处理，则停止委派事件。

阶段实现InputProcessor，您可以创建另一个实施并投入Gdx.input

Stage stage=new Stage();    // your 1st InputProcessor 
InputPorcessor processor=new InputPorcessor();  //2nd InputProcessor 
...             // may be 3rd 

InputMultiplexer inputMultiplexer=new InputMultiplexer(); 
inputMultiplexer.addProcessor(stage); 
inputMultiplexer.addProcessor(processor); 

Gdx.input.setInputProcessor(inputMultiplexer); 

编辑

添加您的阶段，进入你的多路复用器，以这种方式回报：

public InputMultiplexer returnInput(Stage stage) { 

    InputMultiplexer im = new InputMultiplexer(); 
    GestureDetector gd = new GestureDetector(this); 
    im.addProcessor(stage); 
    im.addProcessor(gd); 
    im.addProcessor(this); 

    return im; 
} 

设置返回值：

MyInputProcessor myInputProcessor = new MyInputProcessor(); 
InputMultiplexer im = myInputProcessor.returnInput(stage); 
Gdx.input.setInputProcessor(im);
