I wanted to make a first person shooter game with multiplayer in it. But I want it to be like call of duty where if you kill an enemy player your team gets points. How do I do that? Please help me.
Unfortunately, you can’t “just” make a latest generation, high end multiplayer game without knowing how to program. To put it in perspective, what you’re trying to do is like building a car. I might “just” want to make a car that runs like a Ferrari, but I have to learn things like engineering and welding to be able to do so.
However, there’s good news: you’ve been using Unity for years, so you’re not starting from scratch. Likely you already have a set of skills: perhaps you’re a good artist, or good at level design, or asset creation, or whatever else. Most serious games are created by teams of people, so perhaps you should ask around on the forums to see if anyone is interested in collaborating with you. If you truly want to do this by yourself, you’ll just have to buckle down and learn some programming. However, even that isn’t as bad as it sounds. The Unity website has a number of tutorials that walk you through various parts of game creation, including coding. And, there are a number of excellent tutorials on the forums, including one that I myself followed a while back that teaches you step by step how to put together a multiplayer game. There are also great books and websites for learning C# and JS - just search around for “C# tutorial”, for instance. There are also entire sites dedicated to learning to work with Unity, for instance 3DBuzz.
Good luck!
