im trying to find a way to sort of recursively ‘set and get’ the cloud variable and add 1 to the value of the property ‘playerCount’ when a new user connect via BLE. With the code in the printscreen i can set the value to ‘1’ but if another user connect itself it will not add ‘1’.

How could i achieve that ?

You could do a 2-step approach:

1. Set app variable currentPlayerCount to cloud variable pDSTAL/playerCount
2. Set cloud variable pDSTAL/playerCount to app variable currentPlayerCount + 1

I’m not sure how that would function with many players connecting at once though. You’d need to test it.

but because i ‘set cloud variable’ and never initialized it anywhere i have no block variable related to the cloud value. So, no way to access it as a currentPlayerCount. How do i get the value before ?

to give you a context, this doesnt work :

You use the `cloud variable " "` block at the _bottom_ of the Variables drawer and enter the path to the cloud variable.

The video in the documentation shows one way to do this with `get property of object` blocks: [Connect a Firebase Realtime Database | Thunkable Docs](https://docs.thunkable.com/blocks/blocks/variables-overview/connect-a-firebase-realtime-database#how-to-read-data-in-a-firebase-realtime-database).

I prefer the method shown in this topic: [Cloud variables and user ID](https://community.thunkable.com/t/cloud-variables-and-user-id/1434493).
