Ok so I have a tile entity and everything but I was wondering how I can use the rf api

Take a look at this code, add it to your project, and implement whichever interface you need (depending on what you want to do with RF.

Ive never used this api so I really dont understand how to use it

Well, add it to your project. Then, take a look at the various interfaces and figure out which one applies to what you want to use RF for.

It's quite simple to use, all you need to do apart from adding the files to you project is implement or extend the provided interfaces and classes on your own tile entities.

 

If implemented correctly any mod that uses this API will work with yours

 

For example, if you implement the "IEnergProvider" the tile entity should be a provider of energy and other tile entities will use it to receive energy from it. Now the actual implementation is in your hands, RFApi only gives you the basic interfaces.

 

P.S. Make sure that the files beginning with "I" are never altered as they are the interfaces between mods, changing them will break compatibility

Belopis thanks I know have a better understanding

 

Just wondering how can I make the provider have a internal buffer

Take a look at EnergyStorage, add field which is an instance of EnergyStorage to your TileEntity. But don't forget to have it read and write to NBT when your TileEntity does.
