How to create more advanced like Chop system for trees?

Hello fellow scripters,

I want to ask you all, how to create a more advanced chopping system like you play animation and then you like subtrack a 1 or more depends on "axe" from ex. Wood_Left value inside a log or something else.

So it's pretty easy to make only when Part touches other part to make it chop. I want to know how to combine that two things and how to make Axe to chop ONLY when you press on WOOD and like play animation for axe to swing.

I am not asking you to make the whole script for me, I just want some tips how to get started with this, please help if you have time and if you know my question. I dont have any code because I want to ask you about how to start it even... Please let the answers be concrete.

If you still want some more details: Here they are:

So, If you've ever played BOGGA BOGGA game, you must have seen their Chop system, like, You press on LOG and then play animation and like GUI appears on how much Wood is left, Right now I just want to know how to combine those two things (animation and chop), and how to make axe NOT to chop log before you press or click on Tree (log).
