I actually managed to get most of it to work. I got the interface almost entirely set up, but the latest version of essentials radically differs from previous ones in the scene where you pick the moves. That's the biggest (and only) problem.
I noticed you created a sort of Gold Engine using Essentials. I've been working on a GenII project for a while now ( the thread if you're interested), but have unfortunately run into some problems, especially regarding the battle scene (specifically the sections of the PokemonBattle scripts concerning the parts for picking the moves).
tl;dr Was wondering if you have any experience in the field and, if so, if you would be willing to help me get that into place.
