Script return "attempt to index a nil value" after every death?
Hi guys. This walk script for a Zombie keeps returning the following error right after it's death. It annoys me because nothing is wrong with the code.
20:18:30.178 - Workspace.Lightning Zombie.walk:33: attempt to index a nil value 20:18:30.181 - Stack Begin 20:18:30.182 - Script 'Workspace.Lightning Zombie.walk', Line 33 20:18:30.183 - Stack End
local larm = script.Parent:FindFirstChild("Left Arm")
local rarm = script.Parent:FindFirstChild("Right Arm")
local torso = script.Parent:FindFirstChild("Torso")
function findNearestTorso(pos)
local list = game.Workspace:children()
local torso = false
local dist = 1000
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("Right Arm")
human = temp2:findFirstChild("Humanoid")
Zombie = temp2:FindFirstChild("Zombie")
if (temp ~= nil) and (human ~= nil) and (human.Health > 0) and Zombie == nil then
if (temp.Position - pos).magnitude < dist then
torso = temp
dist = (temp.Position - pos).magnitude
end
end
end
end
return torso
end
while torso ~= nil do
wait()
local target = findNearestTorso(script.Parent:FindFirstChild("Torso").Position) --Problem Here
if target ~= false and target ~= nil then
script.Parent.Humanoid:MoveTo(target.Position, target)
end
end

You've already defined torso on line 3, so use that instead of writing script.Parent:FindFirstChild("Torso") again on line 33.
The problem is that the while loop doesn't stop because the torso doesn't stop existing The torso just has no Parent. Since you're looking for it again on line 33 and assuming it exists since you then try to get its Position, you're trying to get the Position of nothing because Torso isn't here anymore, so what you can do is write while torso.Parent do to correct the while loop, and move the wait() to the bottom of the loop so it doesn't give it time for something to change.
