How can I see the amount of players that are currently playing my game?

Hello!
I have a highscore game and want to multiply the current score of the player by the amount of other players that are playing the game at the same time.
Is there any way I can see how many people are playing my game at the current time and use this data to multiply the score?

Thank you

 

There is no standard functionality to do this in Tiny. You could do it, but then you'd have to build that yourself using databases and stuff.

You'd then carefully have to determine when a player is actually considered "playing" your game. Is that when he has started the game? When he is still on the webpage? By sending life-ticks to the database?

 

I agree with Rupture13, you definitely need your own server side.
Tiny is just a client, there are no multiplayer features and the browser will not allow you to share user data between multiple clients due to browser security restrictions.

You can send in-game request to server when new player is started the game via ajax (see xmlhttprequest reference).
You also will need to make requests for all in-game critical events like a gameover / gamepause / timeout / windowout / windowin / etc - to determine if user still playing the game.
Finally, your server will need to send updatestate event (that will contain current players count) to all active players when players count was changed.
