How to identify a function's logic in ghidra

[mecacool]

Hey, I was curious how one would understand how to identify a function's logic in Ghidra?

For, example, the function maybe is used for a boss fight in-game.
So, how would one understand how this function is for the boss in Ghidra
or is there another way easier to do this?
This way if I understand what it is used for I can rename it something different than the generic function names that Ghidra spits!!
But, first I need to know if one function is used for a boss for example.

Any advice you can provide me??
