libGDX - Android Studio中的Google Play游戏服务

Question

从Eclipse迁移到Android Studio之后,我一直在苦苦挣扎.问题是你可以找到的大多数指南和教程都是针对Eclipse的,但是如果你能找到一个适用于Android Studio的指南和教程,它就缺少了最重要的部分 - 实现库或第三方代码.经过一周的问题和错误,这里是一个指南

Answer 1

要求:Google Play服务和Google Repostory(在SDK管理器中的Extras下),BaseGameUtils

首先,我们需要将BaseGameUtils添加为模块:

然后选择Import Gradle Project并选择BaseGameUtil文件夹(在该步骤之前不要复制项目中的BaseGameUtils.让Android Studio执行此操作)gradle完成后同步selefct Build> Make Module'BaseGameUtils'

注意如果你在构建时有使用-sdk:minSdkVersion错误,请单击此处.在此之后再次构建:BaseGameUtils

整合BaseGameUtils的最后一步是将它包含在android模块中: 之后同步项目.

注意如果你在构建时遇到uses-sdk:minSdkVersion错误,这将有助于 - 链接

现在是时候打开你的AndroidManifest文件了,包括:

在应用标签之前

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

注意:没有必要在android gradle脚本中添加google play依赖项,因为它已经包含在BaseGameUtils中

在申请中,在活动之前

 <meta-data android:name="com.google.android.gms.games.APP_ID"
            android:value="@string/app_id" />
 <meta-data android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

现在你需要在Srtings中设置app_id号码(android/res/values/Strings.xml)

  <string name="app_id">928019648708</string>

您的应用ID位于游戏服务部分下的GooglePlay开发者控制台中(在游戏名称下)

为了将android本机代码传递给游戏代码,我们将在核心模块中创建ActionResolver接口:

package com.mygame.test;

public interface ActionResolver {
    public boolean getSignedInGPGS();
    public void loginGPGS();
    public void submitScoreGPGS(int score, String id);
    public void unlockAchievementGPGS(String achievementId);
    public void getLeaderboardGPGS();
    public void getAchievementsGPGS();
}

现在我们需要在AndroidLauncher类中进行更改(如果遇到问题,请检查导入):

package com.mygame.test.android;

import android.os.Bundle;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;
import com.google.android.gms.games.Games;
import com.google.example.games.basegameutils.GameHelper;
import com.mygame.test.ActionResolver;
import com.mygame.test.MyGame;

public class AndroidLauncher extends AndroidApplication implements ActionResolver, GameHelper.GameHelperListener {

    private GameHelper gameHelper;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (gameHelper == null) {
            gameHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);
            gameHelper.enableDebugLog(true);
        }
        gameHelper.setup(this);

        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        initialize(new MyGame(this), config);
    }

    @Override
    public boolean getSignedInGPGS() {
        return gameHelper.isSignedIn();
    }

    @Override
    public void loginGPGS() {
        if (!gameHelper.isSignedIn()) {
            try {
                runOnUiThread(new Runnable() {
                    public void run() {
                        gameHelper.beginUserInitiatedSignIn();
                    }
                });
            } catch (final Exception ex) {
                Gdx.app.log("MainActivity", "Log in failed: " + ex.getMessage() + ".");
            }
        } else {
            gameHelper.reconnectClient();
        }
    }

    @Override
    public void submitScoreGPGS(int score, String id) {
        Games.Leaderboards.submitScore(gameHelper.getApiClient(), id, score);
    }

   @Override
    public void unlockAchievementGPGS(String achievementId) {
        Games.Achievements.unlock(gameHelper.getApiClient(), achievementId);
    }

    @Override
    public void getLeaderboardGPGS() {
        if (gameHelper.isSignedIn()) {
            startActivityForResult(Games.Leaderboards.getLeaderboardIntent(gameHelper.getApiClient(), "CgkI5MyZk4FbHAJQXQ"), 100);
        } else if (!gameHelper.isConnecting()) {
            loginGPGS();
        }
    }

    @Override
    public void getAchievementsGPGS() {
        if (gameHelper.isSignedIn()) {
            startActivityForResult(Games.Achievements.getAchievementsIntent(gameHelper.getApiClient()), 101);
        } else if (!gameHelper.isConnecting()) {
            loginGPGS();
        }

    }

    @Override
    public void onSignInFailed() {
        gameHelper.getSignInError();
    }

    @Override
    public void onSignInSucceeded() {

    }

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data){
        super.onActivityResult(requestCode, resultCode, data);
        gameHelper.onActivityResult(requestCode, resultCode, data); 
    }
}

在主类中创建构造函数(在此示例中为MyGame):

public ActionResolver resolver;

public Base(ActionResolver ar) {
    resolver = ar;
}

连接gplay服务电话:

if (!resolver.getSignedInGPGS())
    resolver.loginGPGS();

解锁成就并提交分数:

if (resolver.getSignedInGPGS()){
    if (currentScore == 0){
        resolver.unlockAchievementGPGS("CgkI5MyZk4EbEAIQAg");
    }
    if (Cookie.bestScore >= 100){
        resolver.unlockAchievementGPGS("CgkI5MyZk4EbEAIQAw");
    }
    resolver.submitScoreGPGS(Cookie.bestScore, "CgkI5MyZk4EbEAIQAQ");
}

注意:在开发者控制台中为每个成就和leaderbord使用相应的id值

和呼叫排行榜和成就

resolver.getLeaderboardGPGS();
resolver.getAchievementsGPGS();

最后,桌面,ios和html启动器可以以相同的方式解析(桌面启动器的示例)

public static void main (String[] arg) {
    LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();

    ActionResolver resolver= new ActionResolver() {
        @Override
        public boolean getSignedInGPGS() {
            return false;
        }
        @Override
        public void loginGPGS() {
        }
        @Override
        public void submitScoreGPGS(int score, String id) {
        }
        @Override
        public void unlockAchievementGPGS(String achievementId) {
        }
        @Override
        public void getLeaderboardGPGS() {
        }
        @Override
        public void getAchievementsGPGS() {
        }
    };
    new LwjglApplication(new MyGame(resolver), config);
}
