私は Andengine から始めましたが、画面に触れたときにスプライトを動かすのが困難です (スプライトではありません)。私は本当にあなたの助けが必要です、どうもありがとう。

ここに私のコードがあります:

    @Override
protected Scene onCreateScene() {
    final Scene scene = new Scene();
    Sprite backgroundSprite = new Sprite(0, 0, this.mBackgroundTextureRegion, getVertexBufferObjectManager());
    scene.attachChild(backgroundSprite);
    Carl carl = new Carl(1, 30, 361, this.carl, getVertexBufferObjectManager()){

        };

    scene.attachChild(carl);



    this.mStack1.add(carl);
    carl.setmStack(mStack1);
    scene.registerTouchArea(carl);
    scene.setTouchAreaBindingOnActionDownEnabled(true);


    return scene;
}
public boolean onTouchEvent(MotionEvent event, Carl carl) {

    carl.setPosition(carl.getX() +2,carl.getY() );
    return true;
}

IOnSceneTouchListenerボールを操作できる onSceneTouchEvent メソッドをオーバーライドするよりも、インターフェイスを実装できます。

@Override
public boolean onSceneTouchEvent(Scene pScene, TouchEvent pSceneTouchEvent) {
     carl.setPosition(carl.getX() +2,carl.getY() );
    return false;
}

scene.setOnSceneTouchListener(this);ただし、これを追加することを忘れないでくださいprotected Scene onCreateScene()

編集：

boolean canGo = false;

@Override
public boolean onSceneTouchEvent(Scene pScene, TouchEvent pSceneTouchEvent) {
    if (pSceneTouchEvent.getAction() == MotionEvent.ACTION_DOWN)
        canGo = true;
    if (pSceneTouchEvent.getAction() == MotionEvent.ACTION_UP)
        canGo = false;
    return false;
}

そしてこれはあなたに追加しますpublic Scene onCreateScene() {

scene.registerUpdateHandler(new IUpdateHandler() {
    @Override
    public void reset() {}
    @Override
    public void onUpdate(float pSecondsElapsed) {
        // TODO Auto-generated method stub
        if (canGo)
            ball.setPosition(ball.getX() + 2, ball.getY());
    }
});

move修飾子を使用して上下に移動することもできます。
