[ENet-discuss] ENetPacket to std::string

[ingmar wirths]

Thanks for your answers.
I thought there was an easier solution and i was just doing something stupid.

Nuno: Of course, i do not embed my game data into strings. I was just using
this for chat messages. My idea was to send chat messages on a dedicated
channel reliably, and pass them around in my application as strings.

Maybe this approach isn't that sound? How have you guys implemented chatting?

Cheers,
ingmar
