Help with NBT Data and Rendering

[NathanPB]

Hello, Im completly new on Forge and its my first mod, then im sorry for anything stupid :c
Well, Im saving some data (Mana) on Player NBT (server side, I hope) and I want to render its mana on client side.
Well, how do I get the current player to read its nbt? I tried Minecraft.getMinecraft().currentPlayer (or something else, i dont remember), but its returning null

Thanks everyone

NBT is for saving to disk. If you want to store data on a player, use capabilities.

If you need the data on the client (like your use of Minecraft::player implies) you need custom packets as well.

Thanks a lot. What do you think i should use to store client-side only data (like display position)
