Punch animation damage not working?

I KNOW KEYDOWN IS DEPRECATED

Hi, I made an animation where I give a punch. Now, I'd like to give damage when a player or an humanoid get's hit by it. I tried this, not working though.

local player = game.Players.LocalPlayer
repeat wait() until player.Character.Humanoid
local humanoid = player.Character.Humanoid
local mouse = player:GetMouse()
local db = false
local anim = Instance.new("Animation")
local damage = game.ReplicatedStorage.Damage.Value
anim.AnimationId = "http://www.roblox.com/asset/?id=2055511545" -- id of animation


mouse.KeyDown:connect(function(key)
  if db == false then
	if key == "q" then
		db = true
		local playAnim = humanoid:LoadAnimation(anim)
		playAnim:Play()
		wait(1)
		db = false
		game.Players.LocalPlayer.Character.RightHand.Touched:Connect(function(plr)
			local huma = plr:WaitForChild("Humanoid")
			if huma then
				huma.Health = huma.Health - damage
				
			end
		end)
	end
end
end)

###You shouldn’t use KeyDown, use UserInputService or ContextActionService.

-- LocalScript

local plr = game:GetService("Players").LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local dmg = 10 -- set to your damage

function punch()
    if not char:FindFirstChild'PunchAnim' then
        local anim = Instance.new'Animation'
        anim.Name = 'PunchAnim'
        anim.AnimationId = '' -- put your ID here
        anim.Parent = char
    end
    
    local dmgScript = script.DmgScript:Clone()
    dmgScript.Parent = char.RightHand
    dmgScript.Disabled = false
    wait(0.5)
    dmgScript:Destroy()
end

game:GetService("ContextActionService"):BindAction(
    "Punch",
    punch,
    false,
    Enum.KeyCode.Q
)

###Separate server script under the punching local script:

-- Server Script

local dmg = 10

script.Parent.Touched:Connect(function(part)
    if part.Parent:FindFirstChild"Humanoid" then
        if part.Parent ~= script.Parent.Parent then
            part.Parent.Humanoid:TakeDamage(dmg)
        end
    end
end)

just take a sword script, make the mesh invisible and replace the animations, and change the range and/or damage if you need to
