PacketPeer is an abstraction and base class for packet-based protocols (such as UDP). It provides an API for sending and receiving packets both as raw data or variables. This makes it easy to transfer data over a protocol, without having to encode data as low level bytes or having to worry about network ordering.

Deprecated. Use [code]get_var[/code] and [code]put_var[/code] parameters instead.

If [code]true[/code] the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var].
