Hi Viral,
We have completed the feature you were requesting. The new SDK with version 1.10 contains the feature to set the custom next turn in a turn based game. We are updating the site with new download links and creating samples. Please tell me which platform you are targeting and I will give you the link to it.
In new version, startGame takes two parameters. Use true as first parameter if you don't want custom setting of next turn else use false. If you pass false, then you will need to pass the second parameter which will represent the name of first user that you want the game to start with.
Then whenever you are calling sendMove method, you will need to pass an additional second parameter which will represent the user whose next turn has to be. If the player who's next turn was, is not responding, then one of the player will receive onNextTurnRequest notification listener. There you will need to call SetNextTurn API with name of user who has to be given new turn.
Thanks
