How do I change what action(s) cause the player to increase in a given skill?

[drewsbrew]

Hello, all!

 

I'm working on a skill overhaul mod and I have one quick question;

 

As the title says, "How do I change what action(s) cause the player to increase in a given skill?"

 

For context and to clarify, I'm working on a skill overhaul mod, and I want to add an unarmed combat skill. I know you cannot additional slots for skills, so my plan is to add the blocking perks to the armor skill trees, thereby freeing up a slot for a skill, which I will use as the unarmed skill tree. The part I'm stuck on is how to make it so the player can progress in that skill by engaging in unarmed combat instead of by blocking.

 

If anyone is able to offer any help at all, that would be greatly appreciated!

 

Thank you! :)
