Making a script for increasing speed. Any pointers to make this script more efficient?

The script works just fine but I am new to scripting and wondering if anyone has some pointers to make my script more efficient and less space consuming. -Thanks in advance

local Part = script.Parent.Head
	Part.Touched:connect(function(hit)
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
	local chara = workspace:FindFirstChild(player.Name)
	if hit.Parent:FindFirstChild("Humanoid") then
		if chara:FindFirstChild("SpeedTag") then
		else
			if hit.Parent.Humanoid.Health > 0 then
				local hum = hit.Parent.Humanoid
				hum.WalkSpeed = hum.WalkSpeed + 50
				local speedtag = Instance.new("BoolValue")
				speedtag.Name = "SpeedTag"
				speedtag.Parent = workspace:FindFirstChild(player.Name)	
			end

end
end
end)

(The script takes whoever stands on it and adds speed if they havent already stood on it, adds a boolvalue to indicate that they have stepped on it. And if they try to step on it again, nothing happens due to the character having the bool in it.)

-P.S. it needs to add speed instead of setting it because I plan to add other speed boosters so they can stack.

Hi, if you want to reduce lines, i suggest that instead of creating a bool value using instance.new, you just set a bool value for a variable.

For example:

local Part = script.Parent.Head
local speedTag = false
    Part.Touched:connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    local chara = workspace:FindFirstChild(player.Name)
    if hit.Parent:FindFirstChild("Humanoid") then
        if speedTag == false then
            if hit.Parent.Humanoid.Health > 0 then
                local hum = hit.Parent.Humanoid
                hum.WalkSpeed = hum.WalkSpeed + 50
                speedTag = true
            end

end
end
end)

This works a lot like debounce, except that there is no cooldown time. You also don't need the unnecessary else and an if statement the other way around.

Hope this was helpful!
