Programming and maintaining efficient server software is already a very hard task; however, to add even more complexity to this duty, we must deal with latency too. This topic is very broad but we will still try to give you some starting tips on how to deal with these issues.
Roughly, latency is the delay a network packet takes to reach its destination. The bigger the latency, the more we get behind in the networked simulation, and in consequence, the gameplay gets worse.
This little nightmare is one of the hardest troubles to deal with in network programming. It will make players have a different experience based on their connection and other network conditions, that is, it will make the game very smooth for some players while completely unplayable for others; it will be a mess. Unfortunately, it is not in the hands of the programmer to deal with the network's latency at all. A programmer can at best prepare the software to behave a little better in the worst case scenarios, where...
