Tripwire System Cannot Check IDs

[fergusnoot]

It’s been a LONG time since I’ve tried to script anything, so I am relying on tutorials. But so far, none of them can explain this.
Essentially, I am trying to make a tripwire system where if the player touches a part, but they don’t have the right ID in either their hands nor their inventory, it sets off an alarm bell and changes the color of a console to red. I believe the error is the lines where I am trying to check the player for what IDs they have (to determine if the alarm should be sounded).

The error message is: image|637x25 but because I am rusty (and also very stupid) I can’t for the life of me figure out how to fix it.

local alarm = script.Parent.SFX_Alarm
local light = script.Parent.Parent.Tripwire_Console.T1
local debounce = false

script.Parent.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then --- The issue is in the 3 lines below this
		local Tool = hit.Parent:FindFirstChild("Humanoid"):FindFirstChild("M-ID")  or hit.Parent.Character:FindFirstChild("M-ID")
		local Tool2 = hit.Parent:FindFirstChild("Humanoid"):FindFirstChild("R-ID")  or hit.Parent.Character:FindFirstChild("R-ID")
		local Tool3 = hit.Parent:FindFirstChild("Humanoid"):FindFirstChild("D-ID")  or hit.Parent.Character:FindFirstChild("D-ID")
	
		if Tool or Tool2 or Tool3 then return end --- If any of the local tools are found, do not set off the alarm
	
		if not debounce then
			print("Sounding the Alarm!")
			debounce = true
			alarm:Play()
			light.Material = "Neon"
			task.wait(60)
			debounce = false
		end
	end
end)

or hit.Parent.Character:FindFirstChild("M-ID")

The issue is that hit.Parent is your character, not your player, so it doesn’t have a Character. The way you can solve this is to make a variable called player as the first line in the event:

local player = game.Players:GetPlayerFromCharacter(hit.Parent)
if player then
local Tool = hit.Parent:FindFirstChild("M-ID")  or player.Backpack:FindFirstChild("M-ID")
-- copy this for the rest of the tools, then write the rest of the code you have
end
