Can't figure out how to make official roblox weapon system damage non player humanoids?

Using the official Roblox weapons system (https://developer.roblox.com/en-us/articles/weapons-kit) I am completely unsure of why exactly the weapons do not damage non-player humanoids, (ex. NPCs) given the fact that it seems at places within the script it has code to do that. It may not, and I might just be confused. Either way, can someone please please help me and show me how to make the weapons in this kit damage normal humanoids? All help is very much appreciated, thank you.

This uses the official Roblox weapon kit, see an example of it all and contained scripts here: https://www.roblox.com/library/3932996124/Pistol

UPDATE: I may have found where it decides that it only wants to attack players, so I will include the place in the WeaponSystems script (not the entire set of scripts for the guns) I'm guessing is the cause.

*Here is where it finds the humanoid, and also gets the player from it. Maybe editing this would allow it to function on all humanoids? I am not sure how I would go about doing that.*

function WeaponsSystem.getHumanoid(part)
	while part and part ~= workspace do
		if part:IsA("Model") and part.PrimaryPart and part.PrimaryPart.Name == "HumanoidRootPart" then
			return part:FindFirstChildOfClass("Humanoid")
		end

		part = part.Parent
	end
end

function WeaponsSystem.getPlayerFromHumanoid(humanoid)
	for _, player in ipairs(Players:GetPlayers()) do
		if player.Character and humanoid:IsDescendantOf(player.Character) then
			return player
		end
	end
end

Many people make the mistake of using

instance:FindFirstChild("Humanoid") --may or may not be a Humanoid

instead of

instance:FindFirstChildOfClass("Humanoid") --confirmed to be a humanoid

As for your case, the enemy humanoid might not be named 'Humanoid', and the damage script will be using FindFirstChild.

If you would like further assistance, please show the code, as we cannot assist with requests. We can only help if you provide the script.

How did you solve it, i am stuck too
