新版本的GMS的api和老版本的有很大的差异，刚接了一下，在这里留一个记号，以便查阅：
判定是否已经登录
private static boolean isSignedIn(Cocos2dxActivity cocos2dxActivity) {
return GoogleSignIn.getLastSignedInAccount(cocos2dxActivity) != null;
}登录GameCenter
public static void loginGameCenter(Cocos2dxActivity cocos2dxActivity) {
Log.d(TAG, "signInSilently()");
mGoogleSignInClient = GoogleSignIn.getClient(cocos2dxActivity,
new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN).build());
if(!isSignedIn(cocos2dxActivity)){
startSignInIntent(cocos2dxActivity);
}
else {
//静默登录
mGoogleSignInClient.silentSignIn().addOnCompleteListener(cocos2dxActivity,
new OnCompleteListener<GoogleSignInAccount>() {
@Override
public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
if (task.isSuccessful()) {
Log.d(TAG, "signInSilently(): success");
} else {
Log.d(TAG, "signInSilently(): failure", task.getException());
}
}
});
}
}登录按钮点击之后调用:
private static void startSignInIntent(Cocos2dxActivity cocos2dxActivity) {
GoogleSignInClient signInClient = GoogleSignIn.getClient(cocos2dxActivity,
GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN);
Intent intent = signInClient.getSignInIntent();
cocos2dxActivity.startActivityForResult(intent, RC_SIGN_IN);
}提交分数到排行榜
public static void uploadScore(String leaderboard_id,long value,Cocos2dxActivity cocos2dxActivity){
if(!isSignedIn(cocos2dxActivity)){
return;
}
Games.getLeaderboardsClient(cocos2dxActivity, GoogleSignIn.getLastSignedInAccount(cocos2dxActivity))
.submitScore(leaderboard_id, value);
}//显示排行榜
public static void showLeaderboard(String leaderboard_id, final Cocos2dxActivity cocos2dxActivity){
Games.getLeaderboardsClient(cocos2dxActivity, GoogleSignIn.getLastSignedInAccount(cocos2dxActivity))
.getLeaderboardIntent(leaderboard_id)
.addOnSuccessListener(new OnSuccessListener<Intent>() {
@Override
public void onSuccess(Intent intent) {
cocos2dxActivity.startActivityForResult(intent, );
}
});
