Hi, I'm trying to create a knockout combo sidemod that affects the shiny rate of said knocked out pixelmon. I have learned a fair amount of Java at school and it doesn't seem like a complicated task at first glance. What I am wondering is if anyone either: a.) Knows of a sidemod that already does this that would work on a small server b.) Can tell me what libraries I would need to import in order to create a sidemod for a server, is it just forge and the pixelmon jar that I am using?
