local attackHandler = require(RS.AttackHandler) -- Basically does all the moves, this module can be used server sided and client sides as well. Since this is a local script, I use it locally and only for server client VFX replication.

-- Moves
local MoveList = {} -- So there is a class named "Boxer" which is my only class (I plan to add more), but this is simply to find all the moves' settings in the keybinds module.
local className = script.Parent.Name -- The script is currently in a folder named "Boxer." I did this to not hardcode my script and simply just copy and paste the script into another class like "Karate" and change the moves around so it is easier for me.
for i, move in keybinds.Moves[className] do

--Animations

--Combo Number

-- so I use modulus for my jabs to prevent hardcoding. All I do is JabCombo % (current move combo like if it's on move #2) + 1 which I hope as the application reader you understand modulus. BTW I do the + 1 since it will give you 0 if the move is on move 1 soo yeah
