libGDX/Android Studio AdMob 代码到其他类

Question

第一次在这个网站上发帖。我是 libGDX 和 java 的新手。我有 c++ 的中级知识。我的问题是我的 AdMob 代码仅适用于我的 Android Launcher 类（不确定这是有意的还是我遗漏了什么。我似乎无法将库导入其他类）然后我在使用我想要的 AndroidLauncher 代码。

游戏当前在游戏启动时以正确的尺寸显示广告。当我的 else if isGameOver() 被使用（GameRenderer 类）时，我想调用该广告（它目前是一个横幅广告。我最终想将其更改为插页式广告。我理解这些概念有些不同。）。这样当英雄死亡时，它就会显示广告。当游戏重新启动时，我不会担心隐藏它，因为用户可以自己关闭最终的插页式广告。我知道这可能更多是一个逻辑和缺乏知识的问题，而不是 AdMob 和 libGDX 的问题。但是我已经研究了很多，似乎找不到任何对我来说足够有意义的资源来执行。如果您有任何资源，或者您可以帮助我理解我的问题，我将不胜感激。如果我忘记提供您需要的任何信息，请随时索取。我会定期检查这篇文章。

Android 启动器：

游戏世界：

public class GameWorld {
public int score=0;
private float runTime=0;
private GameState currentState;
private Hero hero;
private ScrollHandler scroller;
private Rectangle ground;
private int midPointY;
private GameRenderer renderer;



public enum GameState {

   MENU, READY, RUNNING, GAMEOVER, HIGHSCORE

}

    hero=new Hero(33,midPointY-5,17,12);
    scroller = new ScrollHandler(this, midPointY + 66);
    ground=new Rectangle(0, midPointY + 66, 137, 11);


}
public void update(float delta) {
    runTime += delta;

    switch (currentState) {
        case READY:
        case MENU:
            updateReady(delta);
            break;

        case RUNNING:
            updateRunning(delta);
            break;
        default:
            break;
    }}
private void updateReady(float delta) {
    hero.updateReady(runTime);
    scroller.updateReady(delta);

}


public void updateRunning(float delta){
    // Add a delta cap so that if our game takes too long
    // to update, we will not break our collision detection.
    if (delta > .15f) {
        delta = .15f;
    }
    hero.update(delta);
    scroller.update(delta);

    if (scroller.collides(hero)&&hero.isAlive()) {
        // Clean up on game over
        scroller.stop();
        hero.die();
        renderer.prepareTransition(255,255,255,.3f);

        //AssetLoader.dead.play();
    }
    //if (scroller.collides(hero) && hero.isAlive()) {
       // scroller.stop();
       // hero.die();
       // AssetLoader.dead.play();

    if  (Intersector.overlaps(hero.getBoundingCircle(), ground)) {
        if (hero.isAlive()){
            //AssetLoader.dead.play();
            renderer.prepareTransition(255,255,255,.3f);
            hero.die();
        }
        scroller.stop();
        hero.decelerate();
        currentState = GameState.GAMEOVER;

        if (score > AssetLoader.getHighScore()) {
            AssetLoader.setHighScore(score);
            currentState = GameState.HIGHSCORE;
        }



}}


public boolean isHighScore() {
return currentState == GameState.HIGHSCORE;
}
public boolean isReady() {
    return currentState == GameState.READY;}
public void start() {
    currentState = GameState.RUNNING;
}
public void restart(){
score = 0;
hero.onRestart(midPointY - 5);
scroller.onRestart();
ready();
}
public boolean isGameOver() {
    return currentState == GameState.GAMEOVER;
}
public Hero getHero(){
    return hero;
}

    return scroller;
}

    return score;
}

    score += increment;
}

    currentState = GameState.READY;
    renderer.prepareTransition(0,0,0,1f);

}

这是来自 GameRenderer 类的相关部分。

if (myWorld.isRunning()) {
        drawHero(runTime);
        drawScore();
    } else if (myWorld.isReady()) {
        drawHero(runTime);
        drawScore();
    } else if (myWorld.isMenu()) {
        drawHeroCentered(runTime);
        drawMenuUI();
    } else if (myWorld.isGameOver()) {
        drawScoreboard();
        drawHero(runTime);
        drawGameOver();
        drawRetry();
    } else if (myWorld.isHighScore()) {
        drawScoreboard();
        drawHero(runTime);
        drawHighScore();
        drawRetry();
    }

Answer 1

您无法访问核心模块内的 Android API。核心模块是所有平台的通用部分。

通过interfacing，您可以使用访问平台特定的代码。

在 LibGDX 项目中集成 AdMob 广告

• 横幅广告集成：Adding Admob to libgdx
• 插页式广告集成：How can I implement AdMob Ads in a LibGDX Android project?

Answer 2

在LibGDX中，核心模块一般作为依赖与Android模块分离，所以不能直接从核心模块调用Android模块的功能。

因此解决方案是在核心模块中创建一个名称为AdLoader 的接口，并添加像showAd() 和hideAd() 这样的函数声明。

然后让你的类Android Launcher实现接口，并将其作为构造函数传递给核心模块的FinalDemo类，并保存AdLoader的引用，然后就可以从核心模块调用接口方法了。
