Java 如何让这个骰子代码在AndEngine中显示新的滚动模具？

所以我试图在我的游戏中创造一个场景，比如马里奥派对，掷骰子，打字。但是有一个随机移动的问号骰子，触摸后，应该随机选择一个数字1-6，并显示相应的纹理。但它似乎既没有记录触摸，也没有显示新模具

但到目前为止，只有随机问号骰子运动似乎有效，不会显示任何骰子命中率，实现这一点的最佳方法是什么？如中所示，最佳编码实践。因为这看起来有点不对劲

public class Dice extends Sprite implements IEntity {
private final PhysicsHandler mPhysicsHandler;
Random randomGenerator = new Random();
private float RandomX;
private float RandomY;
private int CAMERA_WIDTH = 960;
private int CAMERA_HEIGHT = 540;

public static Sprite newDiceSprite;

public int mDiceHit;

public Dice(final float pX, final float pY,
        final ITextureRegion pTextureRegion,
        final VertexBufferObjectManager pVertexBufferObjectManager) {
    super(pX, pY, pTextureRegion, pVertexBufferObjectManager);
    this.mPhysicsHandler = new PhysicsHandler(this);
    this.registerUpdateHandler(this.mPhysicsHandler);
    RandomX = randomGenerator.nextInt(3);
    RandomY = randomGenerator.nextInt(3);
    RandomX = RandomX * 100;
    RandomY = RandomY * 100;
    this.mPhysicsHandler.setVelocity(RandomX, RandomY);
}

@Override
protected void onManagedUpdate(final float pSecondsElapsed) {
    if (this.mX < 0) {
        this.mPhysicsHandler.setVelocityX(RandomX);
    } else if (this.mX + this.getWidth() > CAMERA_WIDTH) {
        this.mPhysicsHandler.setVelocityX(-RandomX);
    }

    if (this.mY < 0) {
        this.mPhysicsHandler.setVelocityY(RandomY);
    } else if (this.mY + this.getHeight() > CAMERA_HEIGHT) {
        this.mPhysicsHandler.setVelocityY(-RandomY);
    }

    super.onManagedUpdate(pSecondsElapsed);
}

@Override
public boolean onAreaTouched(final TouchEvent pAreaTouchEvent,
        final float pTouchAreaLocalX, final float pTouchAreaLocalY) {
    switch (pAreaTouchEvent.getAction()) {
    case TouchEvent.ACTION_DOWN:
        // do action when button pressed down.

        rollDice();

        break;
    case TouchEvent.ACTION_UP:
        // do action when button pressed up.
        break;
    }
    return super.onAreaTouched(pAreaTouchEvent, pTouchAreaLocalX,
            pTouchAreaLocalY);
}

public void rollDice() {

    Random rand = new Random();

    mDiceHit = (rand.nextInt(5) + 1);

    if (mDiceHit == 1) {

    } 

    else if (mDiceHit == 2) {

    }

    else if (mDiceHit == 3) {

    }

    else if (mDiceHit == 4) {

    } 

    else if (mDiceHit == 5) {

    }

    else if (mDiceHit == 6) {

        //newDiceSprite = new Sprite(0,0, ResourceManager.dieSideSixTextureRegion, ResourceManager.getInstance().engine.getVertexBufferObjectManager());
        //newDiceSprite.setPosition(400, 200);
        //ManagedGameScene.attachChild(newDiceSprite);
        GameLevel.newDice6();

    }

}

我想，一个简单的开关就可以了

public boolean Roll() {

    ResourceManager.diceShake.play();

    Random rand = new Random();

    switch (rand.nextInt(6) + 1) {

                        .getVertexBufferObjectManager());

        this.attachChild(dice1Sprite);

        break;
