How do you change local script to normal script?

I need help changing this to a normal script because when I press Q I only take damage and not others. I just want them to take damage.

wait(3)

UserInputService = game:GetService("UserInputService")

local players = game:GetService("Players")

local dash = script:WaitForChild("Dash")

local localPlayer = players.LocalPlayer

local tween = game:GetService("TweenService")

local humanoid = localPlayer.Character:WaitForChild("Humanoid")

local humRootPart = humanoid.Parent:WaitForChild("HumanoidRootPart")

local info1 = TweenInfo.new(
	1.3,
	Enum.EasingStyle.Quint,
	Enum.EasingDirection.Out,
	0,
	false,
	0
)

local info2 = TweenInfo.new(
	0.1,
	Enum.EasingStyle.Quint,
	Enum.EasingDirection.Out,
	0,
	false,
	0
)

local db = false

local db2 = false

local db3 = false

local makeTrail = function(A0, A1, Parent, Transparency, Lifetime)
	local t = Instance.new("Trail", Parent)
	t.Color = ColorSequence.new(Color3.new(255, 255, 255), Color3.new(255, 255, 255))
	local a0 = Instance.new("Attachment", A0)
	local a1 = Instance.new("Attachment", A1)
	t.Attachment0 = a0
	t.Attachment1 = a1
	t.Transparency = NumberSequence.new(Transparency)
	t.Lifetime = Lifetime
end

UserInputService.InputBegan:Connect(function(input, gameProccesedEvent)
	if input.KeyCode == Enum.KeyCode.E and db == false then
		db = true
		local endPos = {
			CFrame = humRootPart.CFrame:ToWorldSpace(CFrame.new(0, 0, -60))
		}
		local animation = humanoid:LoadAnimation(dash)
		local move = tween:Create(humRootPart, info1, endPos)
		animation:Play()
		move:Play()
		makeTrail(localPlayer.Character:FindFirstChild("RightUpperArm"), localPlayer.Character:FindFirstChild("RightHand"), localPlayer.Character, 0.7, 0.2)
		makeTrail(localPlayer.Character:FindFirstChild("LeftUpperArm"), localPlayer.Character:FindFirstChild("LeftHand"), localPlayer.Character, 0.7, 0.2)
		wait(0.5)
		localPlayer.Character.RightUpperArm.Attachment:Destroy()
		localPlayer.Character.LeftUpperArm.Attachment:Destroy()
		localPlayer.Character.RightHand.Attachment:Destroy()
		localPlayer.Character.LeftHand.Attachment:Destroy()
		localPlayer.Character:FindFirstChild("Trail"):Destroy()
		wait(0.5)
		db = false
	end
end)

UserInputService.InputBegan:Connect(function(input, gameProccesedEvent)
	if input.KeyCode == Enum.KeyCode.Q and db2 == false then
		db2 = true
		local burst = humanoid:LoadAnimation(script:FindFirstChild("Dash"))
		burst:Play()
		local b = Instance.new("Part", game.Workspace)
		b.Name = "Blast"
		b.BrickColor = BrickColor.new("New Yeller")
		b.Shape = Enum.PartType.Ball
		b.TopSurface = Enum.SurfaceType.Smooth
		b.BottomSurface = Enum.SurfaceType.Smooth
		b.Anchored = true
		b.CanCollide = false
		b.Material = Enum.Material.Neon
		b.Transparency = 0.7
		for i = 1, 20, 2 do
			b.Size = Vector3.new(i, i, i)
			b.CFrame = humRootPart.CFrame
			wait()
		end
		humanoid:TakeDamage(20)
		b:Destroy()
		wait(1)
		db2 = false
	end
end)

You cannot completely convert the script to server script because UserInputService doesn't work on server scripts. What you can do instead is insert a RemoteEvent in workspace and a normal script in the remote event.

In the script you have given, you should do like:

UserInputService.InputBegan:Connect(function(input, gameProccesedEvent)
	workspace.RemoteEvent:FireServer(input.KeyCode)
end)

In this way, the KeyCode will be transferred to the normal script. Then, you can script the rest in the normal script like:

script.Parent.OnServerEvent:connect(function(plr, KeyCode)
	-- the "plr" is the player who pressed the key
	-- the "KeyCode" is the key the player pressed

	if KeyCode == Enum.KeyCode.E then
		
		-- script what happens when player presses E

	elseif KeyCode == Enum.KeyCode.Q then

		-- script what happens when player presses Q

	end 
end)

I hope this helps

Just copy the entire script and add a normal script and delete the local and paste it into the normal script
