I'm trying to get a mana bar to function properly after updating to 1.12, but the main class is riddled with errors due to capabilities being changed a lot since 1.8.9.

 

Here's the mana class: https://github.com/TheSlayerMC/Journey-1.12/blob/master/main/java/net/journey/client/server/DarkEnergyBar.java

 

I didn't touch anything, this is the same code from the 1.8.9 version. It worked almost flawlessly in 1.8.9, but ICabilityProvider changed and the methods that I need to save and load NBT data no longer exist within that class, and there's no longer "registerExtendedProperties()" and "getExtendedProperties()" within the EntityPlayer class. All help is appreciated.

 

There’s part of the forge docs dedicated to this exact issue I believe? Have a look at the docs on capabilities

Took a look at it, seems much less complicated than I thought but it's still stressing me out. Is there a src out there for a mod that adds something similar?

There are many. I know TInkers Construct adds their own.
