Hi, I am trying to create a simple multi user game for my uni dorm, basically between two buildings and each building has around 10 flat mates so say 20 people, each will be in their own room, each has own internet access and a tablet or phone. For example if it is a simple run and collect hamburgers, and the first to collect the target amount wins, and that player's score will be logged as accumulated points, assuming each user will have their unique ID. Which part of Unity will control the multi user play ? as it will have to monitor all 20 devices so they can all start the same time and to see who finished first before logging the user details and points to a database. If this theory is a workable one, my goal is to create one that will allow even more players in each game, I can create a Linux server with mySQL if this is needed to hold scores and ranking. Apologise for such loose question but I am just trying to determine the correct way to approach this and see if it is something within my limit, or something I need to seek real designers. Thanks for any help.
