在LIBGDX中實現遊戲手柄控制器？

Question

我不知道如何實現LIBGDX控制器支持。所以這裏是細節。

比方說，我在這裏以下教程：http://obviam.net/index.php/getting-started-in-android-game-development-with-libgdx-create-a-working-prototype-in-a-day-tutorial-part-1/

Git的在第4部分（這裏我試圖實現一個手柄）的教程是在這裏：https://github.com/obviam/star-assault/tree/part4

我做到最後一步，現在它正在運行，我可以使用鍵盤與角色互動。我現在想通過控制器通過OUYA或通過USB控制字符。

我已閱讀以下內容：http://www.badlogicgames.com/wordpress/?p=2724 我已將jar文件添加到主項目，並已訂購和導出。 我現在已經修改了我GameScreen類如下所示：

import com.badlogic.gdx.Application.ApplicationType; 
import com.badlogic.gdx.Gdx; 
import com.badlogic.gdx.Input.Keys; 
import com.badlogic.gdx.InputProcessor; 
import com.badlogic.gdx.Screen; 
import com.badlogic.gdx.controllers.Controller; 
import com.badlogic.gdx.controllers.PovDirection; 
import com.badlogic.gdx.controllers.mappings.Ouya; 
import com.badlogic.gdx.graphics.GL10; 
import com.badlogic.gdx.math.Vector3; 


public class GameScreen implements Screen, InputProcessor, ControllerListener { 

private World   world; 
private WorldRenderer renderer; 
private CharacterController charactercontroller; 

private int width, height; 

@Override 
public void show() { 
    world = new World(); 
    renderer = new WorldRenderer(world, false); 
    charactercontroller = new CharacterController(world); 
    Gdx.input.setInputProcessor(this); 
} 

@Override 
public void render(float delta) { 
    Gdx.gl.glClearColor(0.1f, 0.1f, 0.1f, 1); 
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); 

    charactercontroller.update(delta); 
    renderer.render(); 
} 

@Override 
public void resize(int width, int height) { 
    renderer.setSize(width, height); 
    this.width = width; 
    this.height = height; 
} 

@Override 
public void hide() { 
    Gdx.input.setInputProcessor(null); 
} 

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

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

@Override 
public void dispose() { 
    Gdx.input.setInputProcessor(null); 
} 

// * InputProcessor methods ***************************// 

@Override 
public boolean keyDown(int keycode) { 
    if (keycode == Keys.LEFT) 
     charactercontroller.leftPressed(); 
    if (keycode == Keys.RIGHT) 
     charactercntroller.rightPressed(); 
    if (keycode == Keys.UP) 
     charactercontroller.jumpPressed(); 
    return true; 
} 

@Override 
public boolean keyUp(int keycode) { 
    if (keycode == Keys.LEFT) 
     charactercontroller.leftReleased(); 
    if (keycode == Keys.RIGHT) 
     charactercontroller.rightReleased(); 
    if (keycode == Keys.UP) 
     charactercontroller.jumpReleased(); 
    return true; 
} 

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

@Override 
public boolean touchDown(int x, int y, int pointer, int button) { 
    if (!Gdx.app.getType().equals(ApplicationType.Android)) 
     return false; 
    if (x < width/2 && y > height/2) { 
     charactercontroller.leftPressed(); 
    } 
    if (x > width/2 && y > height/2) { 
     charactercontroller.rightPressed(); 
    } 
    return true; 
} 

@Override 
public boolean touchUp(int x, int y, int pointer, int button) { 
    if (!Gdx.app.getType().equals(ApplicationType.Android)) 
     return false; 
    if (x < width/2 && y > height/2) { 
     charactercontroller.leftReleased(); 
    } 
    if (x > width/2 && y > height/2) { 
     charactercontroller.rightReleased(); 
    } 
    return true; 
} 

@Override 
public boolean touchDragged(int x, int y, int pointer) { 
    // 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 void connected(Controller controller) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void disconnected(Controller controller) { 
    // TODO Auto-generated method stub 

} 

@Override 
public boolean buttonDown(Controller controller, int buttonCode) { 
    if (buttonCode == Ouya.BUTTON_O) { 
       charactercontroller.jumpPressed(); 
      } 
    return false; 
} 

@Override 
public boolean buttonUp(Controller controller, int buttonCode) { 
    if (buttonCode == Ouya.BUTTON_O) { 
       charactercontroller.jumpReleased(); 
      } 
    return false; 
} 

@Override 
public boolean axisMoved(Controller controller, int axisCode, float value) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean povMoved(Controller controller, int povCode, 
     PovDirection value) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean xSliderMoved(Controller controller, int sliderCode, 
     boolean value) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean ySliderMoved(Controller controller, int sliderCode, 
     boolean value) { 
    // TODO Auto-generated method stub 
    return false; 
} 

@Override 
public boolean accelerometerMoved(Controller controller, 
     int accelerometerCode, Vector3 value) { 
    // TODO Auto-generated method stub 
    return false; 
} 

} 

因此，基於我的理解是如何工作的，當「O」按鈕，當我打開這對歐雅字符應該跳轉現在按下。但沒有任何反應。我想我錯過了一些東西。執行中有任何明顯的錯誤？

我在哪裏與Java在一起，我一直在網絡開發多年，最近剛剛回到Java來玩遊戲和微型控制檯上的交互式東西。我從一個簡單的教程開始，嘗試構建它會是一個好主意，對吧？

期待獲得一些很棒的幫助！

感謝，

嘗試增加：

Controllers.addListener(this); 

權之前：

Gdx.input.setInputProcessor(this); 

setInputProcessor只註冊了內置的輸入事件（按鍵監聽器，觸摸事件等）。控制器是一個外部庫，需要分別進行初始化和加載。您也需要導入com.badlogic.gdx.controllers.Controllers。
