Hello, I'm really new to coding mods (Been roughly 2 months) and I was wondering if anyone could help me out with player properties and packet handling. I was following this tutorial, but then it required a library mod that no longer is available. I'm trying to create an "energy" property (float) that all players have. The modification of it I can do, it's just adding it in, then syncing it with the server I can't. Can I get some help with this?
