I’ve starting to familiarize myself with Sponge and one thing I really need done is to add Essentials to my Pixelmon Server so that I can use Group Manager and all that. I heard something about Essentials was ported into Sponge and I don’t know how to make it work with Sponge. Please if you know how to tell me in the comments below. Thanks in Advanced.
Bukkit plugins use a completely different API than ours. There used to be a plugin called Pore that attempted to bridge Bukkit and Sponge but it was discontinued as mentioned in their thread here
However, there are 3 alternatives for Bukkit essentials on Sponge
Personlly, I think they are quite different - EC does not offer the option to opt out of modules, whereas Nucleus does. Depends on what you want, 10/10 suggest to read the documentation first.
