My ro-bio needle works on NPCs but Not on Players?

I'm trying to make a ro-bio CHAOS game where you can inject other players, the needle works on NPC'S but it just goes right through another player, here's the script in the needle item.

tool = script.Parent


function tween(part,poartpp,spded)
	local tweenService = game:GetService("TweenService")


local tweeningInformation = TweenInfo.new(
	
spded, -- Length
Enum.EasingStyle.Elastic, -- Easing style of the TweenInfo
Enum.EasingDirection.Out, -- Easing direction of the TweenInfo
0, -- Number of times the tween will repeat	
false, -- Should the tween repeat?
0.1 -- Delay between each tween	
)


local Tween = tweenService:Create(part,tweeningInformation,poartpp)
Tween:Play()
end





local RunService = game:GetService('RunService')
 




















local both = script.Parent.Needle

local needle = both.metal
weld = needle.Weld

usable = true
can = true


both.bio.Virus.Changed:connect(function()
	if both.bio.Virus.Value ~= nil then
		if both.bio.Virus.Value.Name == "Biologic" then
			both.bio.BrickColor = BrickColor.Random()
		else
			both.bio.BrickColor = game.Lighting:FindFirstChild(both.bio.Virus.Value.Name .."C").Value
		end
	
	else
		both.bio.BrickColor = BrickColor.new("Medium stone grey")
	end
end)


tool.Activated:connect(function()
	if usable then
	if can then
	can = false
	needle.Sound:Play()
	tween(weld,{C1 =weld.C1 * CFrame.new(2,0,0.2)},0.5)
	wait(0.7)
		tween(weld,{C1 =weld.C1 * CFrame.new(-2,0,-0.2)},0.5)
		wait(1)
		
		can = true
	
	end
	end
end)







both.Hit.Touched:connect(function(hit)
	if usable then
if can == false then if hit.Parent:FindFirstChild("Humanoid") then if hit.Name ~= "HumanoidRootPart" and hit.Anchored == false  then	
	if not game.Players:FindFirstChild(hit.Parent.Name) then
	local huma = hit.Parent:FindFirstChild("Humanoid")
	if (both.bio.Position - hit.Position).Magnitude < 1 then
usable = false
	hit.Parent.Humanoid:TakeDamage(6)
		local tos = needle.CFrame:toObjectSpace(hit.CFrame)
	local new = both:Clone()
	new.metal.Weld:Remove()
	new.Parent = hit
local we = Instance.new("Weld",new.metal)
	we.Part0 = new.metal
	we.Part1 = hit
we.C1 = tos:inverse()
	
	new.metal.CanCollide = true
		new.bio.CanCollide = true
	needle.Transparency = 1
	both.bio.Transparency = 1
	
	
		local sond = Instance.new("Sound",hit)
	sond.SoundId = "rbxassetid://1306077413"
	sond:Play()
	sond.PlaybackSpeed = 2
	sond.Volume = 2
	wait()
		local sond = Instance.new("Sound",hit)
	sond.SoundId = "rbxassetid://1751518775"
	sond:Play()
	sond.PlaybackSpeed = math.random(6,10)*0.1
	sond.Volume = 1
	if new.bio.Virus.Value ~= nil then
	local virus =  new.bio.Virus.Value:Clone()
	
virus.Parent = hit.Parent	
virus.Name = "Biologic"
	end
	
	wait(3)
	both.bio.Virus.Value = nil
	usable = true
		needle.Transparency = 0
	both.bio.Transparency = 0.5
	end
end
end
end
end
	end
end)

and it really DOES work on NPCS i have no idea why doesn't it on Players.

Hello! I recommend changing this line:

if can == false then 
	if hit.Parent:FindFirstChild("Humanoid") then 
		if hit.Name ~=  hit.Anchored == false  then  

I removed the check for the HRP(HumanoidRootPart), as usually NPC's don't have that, but players do. Hope it helps!
