Hi,
we are developing a multiplayer-networking game… 
Our project should be able to access data from a remote database… :?
Wich is the best protocol for a security data transmission in Unity3d, you know? :?:
Do you have any example or script about it?
Just another question, is there different between RPC transmission in the game and the data access to database?
Thanx for your help…
Phew, this depends on how you build it.
Do you control all servers yourselves? Then its pretty secure to have the database right next to the server and, of course, only let the server talk to the database.
I wouldn’t worry about the server-database security then (assuming the server is secure and local-access only… etc.).
Hmm lots, where to begin :P? At this point it’s probably better to read up on the RPC stuff (http://unity3d.com/support/documentation/Manual/Networked%20Multiplayer.html), so you get a better overview of this all and can ask more detailed questions.
