THIS IS SOLVED IT WAS BECAUSE I DIDN'T ANCHOR IT?!

local Pfs = game:GetService("PathfindingService")

local human = script.Parent.Humanoid
local torso = script.Parent
local man = workspace:WaitForChild("Auxigin")
local cry = script.Parent.Cry
local idiot = true
local easy = true

local path = Pfs:CreatePath()
while wait(0.001) do
path:ComputeAsync(script.Parent.PrimaryPart.Position, man.HumanoidRootPart.Position)
local waypoints = path:GetWaypoints()
end

for i, v in pairs(waypoints) do
	human:MoveTo(v.Position)
	human.MoveToFinished:Wait()
end

if human.Health < 100 then
	if idiot == true then
		idiot = false
		script.Parent.Head.face.Texture = "http://www.roblox.com/asset/?id=861024822"
		script.Parent.Head.BrickColor = BrickColor.new("Bright red")
	cry:Play()
	wait(10)
	human.Health = 100
	cry:Pause()
	script.Parent.Head.BrickColor = BrickColor.new("Lime green")
	script.Parent.Head.face.Texture = "http://www.roblox.com/asset/?id=15175343"
	idiot = true

end
end

This is the script, it doesn't work on a cube with eyes though, is there anything wrong? Or can pathfinding only be used with characters?

This is because of your while loop. This is running forever, and the rest of the script doesn't run.
