How to keep weapon swinging while Left Mouse Button is Down?

Hi!

I got a Tool that I want to keep swinging while the left mouse button is down. I've tried following the UserInputService on the wiki and its confusing me. How would I incorporate this service into ensuring the Player's tool keeps swinging as long as the left mouse button is down? I reverted my script back to where it works fine with multiple clicks.

Local Script 1

local tool = script.Parent
local event = tool:WaitForChild("RemoteEvent")

event.OnClientEvent:connect(function(...)
    local tuple = {...}
    if tuple[1] == "RunAnimation" then
        local anim = tool:FindFirstChild(tuple[2])
        if anim and humanoid then
            local loadedanim = humanoid:LoadAnimation(anim)
            if loadedanim then
                loadedanim:Play()
                if themouse then
                    themouse.Icon = "rbxasset://textures\\GunWaitCursor.png"
                    wait(1)
                    themouse.Icon = "rbxasset://textures\\GunCursor.png"
                end
            end
        end
    end
end)


tool.Equipped:connect(function(mouse)
    themouse = mouse
    humanoid = tool.Parent:FindFirstChild("Humanoid")
    if humanoid then
        local anim = tool:FindFirstChild("IdleAnim3")
        if anim and humanoid then
            if loadedidleanim then
                loadedidleanim:Stop()
            end
            loadedidleanim = humanoid:LoadAnimation(anim)
            if loadedidleanim then
                loadedidleanim:Play()
            end
        end
        local anim = tool:FindFirstChild("EquipAnim")
        if anim and humanoid then
            local loadedanim = humanoid:LoadAnimation(anim)
            if loadedanim then
                loadedanim:Play()
            end
        end
    end
    if themouse then
        themouse.Icon = "rbxasset://textures\\GunCursor.png"

    end
end)

tool.Unequipped:connect(function()
    if loadedidleanim then
        loadedidleanim:Stop()
    end
end)

Local Script 2 slightly abbreviated:

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local tool = script.Parent
local Damage = 1
local coolDown = 0.5
local range = 10
local bin = true


function isEquipped()
    if tool.Parent.Name ~= "Backpack" then
        return true
    else
        return false
    end
end

mouse.Button1Down:connect(function()
local tor = plr.Character.UpperTorso    
    if isEquipped() and bin then
        local target = mouse.Target
        if target.Parent.Name == NAME then
 if (target.Position-tor.Position).magnitude <= range then
local Selec = Instance.new("SelectionBox")
        Selec.Adornee = target
        Selec.Color3 = Color3.new(0,1,1)
        Selec.Parent = target       

    Selec:Destroy() 
end 
        end
    end
end)

Server Script:

local tool = script.Parent

local speedboost = 1.5
local damage = 0
local swingtime = .5
local combowindow = .5


local debris = game:GetService("Debris")
local handle = tool:WaitForChild("Handle")
local event = tool:WaitForChild("RemoteEvent")
local slashsound = handle:WaitForChild("SlashSound")
local overheadsound = handle:WaitForChild("OverheadSound")
local lungesound = handle:WaitForChild("LungeSound")

local lastclick = tick()
local combo = 0
local hithumanoids = {}



handle.Touched:connect(function(hit)
local humanoid = hit.Parent:FindFirstChild("Humanoid")
if humanoid then
local TargetPlayer = game.Players:GetPlayerFromCharacter(humanoid.Parent)
    if equipped and character and humanoid and humanoid.Health > 0 and hit and not hit:isDescendantOf(character) then
        if  humanoid and  humanoid.Health > 0 and not hithumanoids[humanoid] and (TargetPlayer and TargetPlayer.TeamColor ~= player.TeamColor or not TargetPlayer)
            then
            hithumanoids[ humanoid] = true

            for _, v in pairs( humanoid:GetChildren()) do
                if v and v.Name == "creator" then
                    v:remove()
                end
            end
            local tag = Instance.new("ObjectValue")
            tag.Name = "creator"
            tag.Value = player
            debris:AddItem(tag, 3)
            tag.Parent =  humanoid
             humanoid:TakeDamage(damage * (combo + 1))
            else

        end 
    end 
end
end)


tool.Activated:connect(function()
    local clickdelta = tick() - lastclick
    if clickdelta > swingtime then
        lastclick = tick()
        hithumanoids = {}
        if clickdelta < swingtime + combowindow then
            combo = (combo + 1) % 3
        else
            combo = 0
        end
        if player then
            if combo == 0 then
                event:FireClient(player, "RunAnimation", "SlashAnim2")
                slashsound:Play()
            elseif combo == 1 then
                event:FireClient(player, "RunAnimation", "ThrustAnim2")
                overheadsound:Play()
            elseif combo == 2 then
                event:FireClient(player, "RunAnimation", "OverheadAnim2")
                lungesound:Play()
            end
        end
    end
end)


tool.Equipped:connect(function()
    equipped = true
    lastclick = tick()
    combo = 0
    character = tool.Parent
    player = game.Players:GetPlayerFromCharacter(character)
    humanoid = character:FindFirstChild("Humanoid")
    if humanoid then
        humanoid.WalkSpeed = humanoid.WalkSpeed * speedboost
    else
        character = nil
    end
end)

tool.Unequipped:connect(function()
    equipped = false
    if humanoid then
        humanoid.WalkSpeed = humanoid.WalkSpeed / speedboost
    end
    character = nil
    humanoid = nil
end)

How would I incorporate this service? Thanks!
