Question

我一直在尝试将Google Play服务应用到我的LibGDX游戏中，并且一直在使用实时多人游戏APK。

然而，在每个人都通过自动匹配加入房间后，我尝试通过调用方法来更改屏幕来启动游戏，但是我得到了如下错误。即使我删除了方法的内容，仍然会发生相同的错误。谁能开导我？

谢谢！

控制台中记录的错误是

java.lang.RuntimeException：传递结果失败   ResultInfo {who = null，request = 10002，result = -1，data = Intent {（has   额外的）}}到活动   {} com.mygdx.game/com.mygdx.game.AndroidLauncher：   显示java.lang.NullPointerException

引起：java.lang.NullPointerException                                                          在com.mygdx.game.GSGameHelper.onActivityResult（GSGameHelper.java:76） - ＆gt;   它指向this.game.multiplayerready（）

代码如下：

 public void onActivityResult(int request,int response, Intent data){
    if (request == GSGameHelper.RC_WAITING_ROOM){
        if (response == Activity.RESULT_CANCELED || response == GamesActivityResultCodes.RESULT_LEFT_ROOM ){
            Games.RealTimeMultiplayer.leave(getApiClient(), this, mRoomID);
            activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
            BaseGameUtils.showAlert(activity, "Left Room");
        }else{
            BaseGameUtils.showAlert(activity, "Game Starting!");
            this.game.multiplayerGameReady();
        }

    }
    else if (request == GSGameHelper.RC_SELECT_PLAYERS){
        if (response != Activity.RESULT_OK) {
            // user canceled
            return;
        }

        // get the invitee list
        Bundle extras = data.getExtras();
        final ArrayList<String> invitees =
                data.getStringArrayListExtra(Games.EXTRA_PLAYER_IDS);

        // get auto-match criteria
        Bundle autoMatchCriteria = null;
        int minAutoMatchPlayers =
                data.getIntExtra(Multiplayer.EXTRA_MIN_AUTOMATCH_PLAYERS, 0);
        int maxAutoMatchPlayers =
                data.getIntExtra(Multiplayer.EXTRA_MAX_AUTOMATCH_PLAYERS, 0);
        Gdx.app.log("J", "Jmin" + minAutoMatchPlayers + " Jmax:" + maxAutoMatchPlayers);
        for (String invitee : invitees){
            Gdx.app.log("L" , invitee);
        }
        if (minAutoMatchPlayers > 0) {
            autoMatchCriteria = RoomConfig.createAutoMatchCriteria(
                    minAutoMatchPlayers, maxAutoMatchPlayers, 0);
        } else {
            autoMatchCriteria = null;
        }

        // create the room and specify a variant if appropriate
        RoomConfig.Builder roomConfigBuilder = makeBasicRoomConfigBuilder();
        roomConfigBuilder.addPlayersToInvite(invitees);
        if (autoMatchCriteria != null) {
            roomConfigBuilder.setAutoMatchCriteria(autoMatchCriteria);
        }
        RoomConfig roomConfig = roomConfigBuilder.build();
        Games.RealTimeMultiplayer.create(getApiClient(), roomConfig);

        // prevent screen from sleeping during handshake
        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    }else{
        super.onActivityResult(request, response, data);
    }
}

public class MacroHardv2 extends ApplicationAdapter {
public void multiplayerGameReady(){
    //gamew.multiplayer = true;
    //Gdx.app.log("EMPEZANDO", "Starting Game");
    //gsm.set(new PlayState(gsm));
    //dispose();
}
}

这是我发起课程的地方

public class AndroidLauncher extends AndroidApplication implements ActionResolver{
private GSGameHelper _gameHelper;

@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    _gameHelper = new GSGameHelper(this, GameHelper.CLIENT_GAMES);
    _gameHelper.enableDebugLog(false);

    GameHelperListener gameHelperListerner = new GameHelper.GameHelperListener() {

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

        }

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

        }
    };
    _gameHelper.setup(gameHelperListerner);
    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();config.useImmersiveMode = true;
    initialize(new MacroHardv2(this), config);
}

并且类构造函数如下

public MacroHardv2(ActionResolver actionResolver) {
    this.actionResolver = actionResolver;
    actionResolver.setGame(this);
}

您正在尝试致电

this.game.multiplayerGameReady();

但你可能没有在任何地方设置“this.game”。你在哪里定义了你的“游戏”对象。你能否展示你定义它的代码块，并设置它，或者实例化它。

所以“this.game”是您尝试使用的空对象。
