hi
i want to create a simple game with online leaderboards that include players names and scores and players had UniqeID
i have my own host and server but i dont know how to code online leaderboards.
there was some videos and i look all of them but no one of them was complete and clear.
i want to do some thing fundamental not easy way or use plugin for leaderboard. i want code a simple leaderboards and use my own host.
all things i know is that i should create database and table 
but i dont know how to code it.
please someone help me.
I just implemented leaderboard functionality into my game, so I can be of some help.
Essentially, here’s a high-level overview of what I did:
- Create your leaderboard on a BaaS solution (I picked Braincloud because it offers native support for gamification features and comes with a handy Unity SDK).
- Make your game authenticate with Brainclould - anonymously or through Facebook
- At defined points in the game, send the score back to the server for storage and pull the updated leaderboard from the server in the form of a JSON file
- Parse the JSON into the corresponding variables that then get displayed in the UI
Note that how you choose to authenticate will determine what gets displayed in the leaderboard - for example, if you choose to go with anonymous identification, you’ll find it impossible to associate a user’s score with anything other than their device ID. For this reason, it’s often better to link leaderboards with Facebook (then you can display the user’s real-life name next to their score) or a dedicated authentication solution which stores their displayed username on the server.
Hope it helps - if you choose to go with Braincloud, I can take a look at the code, too.
