I ended up doing the same as you, I went over the documents and just checked out how some mods were structured and kinda went off of that. The documents provided are vague and a little hard for someone who never used unity before to understand lol, ended up googling everything.
Hi again, you should see what Kikirio said, I'll quote him here
QuoteYeah it is a case of having a look at a few simple mods to get an idea of the structure, the un-compiled server is here and you can find everything you could want to hook into there. After that its all java script know how
As soon as I got my hands on the uncompiled Server, man I'm doing all sorts of stuff, if you had any C# background you'll handle javascript like a beast, if not, it's very easy to understand if you give the time to it ^_^! I already created new presets that traders sell, added a trader (with a LOT of help from Kikirio's mod) that sell's all the stuff I need, except it's way more expensive, to give more easy access but making me have to go make some money first. I changed the damage values and ricochet chances, I changed how the bots spawn, bla bla bla.
The uncompiled server has literally everything you need to start :D! Just look at how the most basic mods are created and start from there!
