Trouble With Mods (new)

[pyroflash 5]

I am extremely new to mods, I just started two days ago after getting notions on how to make the game better for my personal play style, however cannot figure out, for the life of me, what is going on.

So far I've figured out:

1. You need to define external dependencies if you want to use them.

2. Unless you are creating a custom class, you need it to simulate something else before it does anything.

3. You can do most normal operations, call other functions, and the structure is pretty normal.

What I can't figure out:

1. Why BIS repeatedly writes code like this

class ViewOptics: RCWSOptics
			{
			};
			class ViewGunner: ViewOptics
			{
                               };

2. How to remove things that have already been put into effect in previous code structures. (e.g., if I wanted to remove night vision from a scope or a turret camera).

3. Where some of the stuff is originally defined. F.e. I can't easily figure out where RCWSOptics is originally written.

4. How EXACTLY the class structure works, and where it is appropriate to simulate another item, an item's "base", or have a class simulate itself.

Thank you in advance for helping me through the start of this journey.
