Topic: Network Protocol Question - packet loss and lag.

Hi everyone,

A little coding question about network stuff.
If i send a NETMSG / NETEVENT to a client and the client has some lag or packet loss,
do i have to take care of resending, does the tcp/ip protocol do it for me or does maybe even teeworlds-engine resend the packet?
Would be nice to know if a NETEVENT i send really arrives at a client.

Fishy

The teeworlds-engine is resending lost packets. The UDP protocol doesn't take care about packet loss.
Correct me if I'm wrong

Packets are resent only if marked vital.

The network buffer will be flushed out (sent) without waiting for further data.
