This is my first plugin and I would really appreciate any kind of constructive criticism! I'm also new to coding, in Java and in Minecraft aswell.
Anyway I'll leave the source code in case anybody wants to check if I did good or not.
I don't know if it's important but I'm using the presetted libraries for minecraft spigot server provided by Intellij IDEA if you want to take a look at the code.
