How can I make this script find a player's "Humanoid" that isn't called "Humanoid"?

In the game I'm creating the player's Humanoid name gets changed to "Player". When this happens the script will no longer work correctly. I tried many different things but nothing seemed to work. I'm an amateur scripter so I don't know all the ropes.

function findNearestTorso(pos)
	local list = game.Workspace:children()
	local torso = nil
	local dist = math.huge
	local temp = nil
	local human = nil
	local temp2 = nil
	for x = 1, #list do
		temp2 = list[x]
		if (temp2.className == "Model") and (temp2 ~= script.Parent) then
			temp = temp2:findFirstChild("Torso")
			human = temp2:findFirstChild("Humanoid") -- I tried changing Humanoid to "Player" but it didn't work either.
			if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
				if (temp.Position - pos).magnitude < dist then
					torso = temp
					dist = (temp.Position - pos).magnitude
				end
			end
		end
	end
	return torso
end




while true do
	wait(0.1)
	local target = findNearestTorso(script.Parent.Torso.Position)
	if target ~= nil then
		script.Parent.Humanoid:MoveTo(target.Position, target)
	end

end

What you're looking for is a method called FindFirstChildOfClass().

FindFirstChildOfClass() searches for an Instance by the given ClassName regardless of its name. Like FindFirstChild(), FindFirstChildOfClass() has a boolean recursive you can use for descendants.

For example, let's say we have a dummy rig containing a Humanoid named Soul. You can't do FindFirstChild("Humanoid") because FindFirstChild() searches by Name, not ClassName. You would use FindFirstChildOfClass("Humanoid"), which searches for any Humanoid regardless of its Name.

Example code:

local dummy = workspace:FindFirstChild("Dummy")
if dummy then
	if dummy:FindFirstChildOfClass("Humanoid") then
		print(dummy:FindFirstChildOfClass("Humanoid").Name) -- Prints Soul
	end
end

If the Humanoid is not named Humanoid, change "Humanoid"s name in the script to the Humanoid's name.

Very simple in fact, instead of using :FindFirstChild("Humanoid")

All you have to do is use

 :FindFirstChildOfClass("Humanoid")

or

FindFirstChildWhichIsA("Humanoid")

both of them work.
