Wrong Base64 encoidng

Tue, 16 Oct 2018 15:06:13 +0000

I tried using Base64 encoding/decoding in JS for non-latin symbols in leaderboard, but run into problem - It doesn't encode russian symbols correctly

Here is example - I try encoding username "Женя".
JS script displays username, followed by encoded name, followed by decoded encoded name

However, the output is incorrect:

Is there any solution other than forbidding non-latin usernames?

Encoding problem with non-latin characters

Mon, 15 Oct 2018 19:23:36 +0000

Here is a problem I've encountered when was using leaderboard API.

When a user sends russian name to a leaderboard, It behaves strangely - on "Leaderboard" section it displays his name correctly, but on "Scores" it displays "????". Actually, It is a minor problem on itself, because I could've just referenced it by scoreId to find in "Scores" table.

But here is a strange bug I've found:
If I delete score of user with non-latin nickname, it actually only deletes it in "Scores" section (where it is displayed as "????") but not from the leaderboard and the game itself. Moreover, I can't find a way to delete a score of user with broken nickname - it only deletes it in "Scores", but not in "LeaderBoard".

Is there a way to fix it other then Base64 encoding?

updating key by query...

Thu, 30 Mar 2017 12:43:26 +0000

why there is no UpdateKeyByQuery() service??

because i have a complex query to find a document...
now, i need to update a key of this perticular document..,

i can do this by UpdateDocumentByQuery, but for this i have to pass whole new document to be updated. And i dont know the other KeyValues of that document...
i want to just update a single key...

now, this also can be achived by 2 seperate request.. first to get the whole document and then update it.
But i need to do this in single request only because there are chances of concurrent updations by different users...

So, how do i achieve this??
Something like UpdateKeyByQuery() would have saved mee...
kindly help me plzz...

choosing right approach for loaderboard...

Thu, 02 Mar 2017 10:42:21 +0000

My game requires an alltime leaderbord in which everytime after a win some score would be added to previously stored score .... and also a daily leaderboard where all the records would be zeroed at the end of the day.
So for alltime, i am following the below approach..

# saveUserScore() for the first time, and after that for every score updation(win), getLastScore() and change it with some new score
So, is this approach okay?

and if so, how do i manage daily leaderboard with this??

or if i am absolutely wrong with all this, kindly suggest me how to do it..
thanks in advance...

User Service or Storage Service for saving users without email and password?

Wed, 01 Mar 2017 06:44:35 +0000

My app doesn't require email and password for user. it should just create a user and store/access its addition info. So, because email and password are mendatory, should i use some junk values OR should i forget about User Services and directly use Storage Service to save users and related data????

Number of entries in leaderboard

Sun, 16 Oct 2016 18:32:57 +0000

Hi All! I really like the feature of Mini Metro, that it displays my score as "top 20%". I'd like to implement it, but I couldn't figure which API would be the best to use to query total number of players in game. (I'd calculate based on rank, and total ranks). Thanks, Gabor

update: I've solved it by a hack, added a user with 1 point for all levels (games) and getting its score as well.

API Gateway Authentication Signature Not Valid

Sat, 08 Oct 2016 15:20:59 +0000

I'm trying to add an authetication policy to my API, I have created a test API called HelloWorld, i have created an IAM and an authetication policy of type Key.

I am testing in the "Test API and View Specs" section, i am generating the signature and timeStamp on my machine using this code: https://github.com/shephertz/App42_APIGatewayUtillity

I am calling the signature function like this: generateSignature(apiName, apiVersion, apiKey, secretKey, body); using the following initialization:

String apiName = "HelloWorld";//"LigaEndesa";

String apiVersion = "1.0";

String apiKey = IAM_KEY;

String secretKey = IAM_SECRET_KEY;

String body = "hello";

I think all is correct, but when i do the request it says "Signature Not Valid".

What is the error??

Thanks!
