Define The Behavior

Now, after we created our first ability we need to define its custom behavior. Right now, lets make it print something when player starts the ability and add a small cooldown for it:

TypeScript

attack.ts

import { Skill, SkillDecorator } from "@rbxts/wcs";

@SkillDecorator
export class Attack extends Skill {
	public OnStartServer() {
		print("Hi, attack just started!");
		this.ApplyCooldown(3) // 3 second cooldown
	}
}

Luau

attack.lua

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local WCS = require(ReplicatedStorage.WCS)

local Attack = WCS.RegisterSkill("Attack")

function Attack:OnStartServer()
	print("Hi, attack just started!")
	self:ApplyCooldown(3) -- 3 second cooldown
end

return Attack

Okay! That's great, but let's start our ability!
