Google 玩游戏 - 是否可以只为我的游戏过滤用户的经验值？

Question

我有一个应用程序，我在其中使用 Google Play Games 实现游戏化。当用户发布成就时，我需要知道该用户的总分是多少，仅通过我的应用进行过滤。例如，假设我的应用尝试获得 10 个成就，而用户已经发布了其中的 4 个。如何知道该用户发布的这4个成就所产生的总分？有一种简单轻便的方法可以做到这一点吗？

更新

好吧，我试过这个代码，但是 return 零。

    public abstract class GetAchievements {
    public void loadAchievements() {
        PendingResult<Achievements.LoadAchievementsResult> pendingAchievements = Games.Achievements.load(mGoogleApiClient, true);
        pendingAchievements.setResultCallback(new ResultCallback<Achievements.LoadAchievementsResult>() {
            @Override
            public void onResult(Achievements.LoadAchievementsResult loadAchievementsResult) {
                Game game = Games.GamesMetadata.getCurrentGame(mGoogleApiClient);
                extractAchievements(loadAchievementsResult, game);
            }
        });
    }

    public void extractAchievements(Achievements.LoadAchievementsResult loadAchievementsResult, Game game) {
        AchievementBuffer buffer = loadAchievementsResult.getAchievements();
        List<Achievement> achievementList = new ArrayList<>();
        for (int i = 0; i < game.getAchievementTotalCount(); i++) {
            achievementList.add(buffer.get(i));
            Achievement a = buffer.get(i);

            // aways return 0
            Log.d(TAG, "XP = " + a.getXpValue());

        }
        notifyAchievements(achievementList);
    }

    public abstract void notifyAchievements(List<Achievement> achievementList);
}

Answer 1

您可以尝试使用 com.google.android.gms.games.achievement 包中的 Achievement Class。

getXpValue

XP value given to players for unlocking this achievement.

这里还有 Adding Achievements to Your Android Game 的文档：

This guide shows you how to use the achievements APIs in an Android application to unlock and display achievements in your game.

Displaying achievements

To show a player's achievements, call getAchievementsIntent() to get an Intent to create the default achievements UI. Your game can then bring up the UI by calling [startActivityForResult](https://developer.android.com/reference/android/app/Activity.html#startActivityForResult(android.content.Intent, int)). In the following snippet, REQUEST_ACHIEVEMENTS is an arbitrary integer used as the request code.

startActivityForResult(Games.Achievements.getAchievementsIntent(mGoogleApiClient),
REQUEST_ACHIEVEMENTS);
