/*
|
|
* To-do:
|
|
* - Analog support
|
|
* - Some sort of connection control, it only sends packets
|
|
* but there is no acknoledgement of a connection o keepalives
|
|
* - Send player name
|
|
* - Render something on-screen maybe a gui to configure IP and port
|
|
instead of the ridiculously long strings we're using now
|
|
* - Allow changing IP address and port in runtime
|
|
* - Support other platforms
|
|
* - Input recording / Combos
|
