I am trying to create a count of how many people have completed my app, so that when someone does complete it, they can see how many others have before them. It is similar to a leaderboard, but much less complicated. I am having a hard time finding an answer to this online; will I need to create a server to do this, or is there a simpler way to do it just inside unity? Any advice would be much appreciated, thank you!
Since its a rather simple job, why not implement Firebase into your app? For mobile only purposes, they do provide simple ways to save data.
Check firebase database to see if this is for you.
Of course you need a server for this. Well in theory you don’t but this would be by far more complicated (setting up your own decentral network like bittorrent with DHT). How else would you think that information from people around the world could be accessed?
The overall complexity of keeping track of a single count value on a server isn’t much smaller than creating a leaderboard.
I don’t know what you expect from us. Since you seem to have zero knowledge or experience in those fields I have no idea where to start. We can not explain everything from ground up.
