I am trying to create a mod, and I am trying to make a whole new system of energy units, etc. How exactly do I go by doing this? Also, how do you actually implement the RF libraries (container specifically) into a block (with example code please)? I am trying to make a universal storage machine.
You are a new modder. So am I. STAY AWAY FROM THIS STUFF. It is insanly hard, if you don't know what you're doing. Learn java, then practice for a few years at simpler mods, getting slowly more complex, and work your way up.
You'll need to download Redstone Flux (RF?) libraries and add them to your workspace. I can't help you anymore since I never worked with mods like that, but I assume the mod has documentation / tutorials on it's API.
Well you can't just create a new energy system. You'll need basic blocks / items that can utilize your energy. You can store any required data in their nbt.
