Attempt to index nil with number

Help and Feedback Scripting Support

I’m trying to create a AI for Baldi but I keep on getting attempt to index nil with number for some reason.

--Main AI for baldi

--//Settings
local Range = 50000

--//Variables
local Players = game:GetService("Players")

local HRP = script.Parent:WaitForChild("HumanoidRootPart") or script.Parent:WaitForChild("Torso")

--//Stuff

local function GetTheClosestNumber(tab)
	local tier = 0 --The smallest number to return
	local lastValue --The value before current value
	
	for index, value in pairs(tab) do --Loop the table
		--print(index.." looped") --Print the index like this " "index.." looped" "
		value = tonumber(value) --Make the value to a number just in case
		lastValue = tab[index - 1] or -50 --The index before the current index or the last value
		
		if value[2] < lastValue then --Compare the value
			--If it's smaller than the last value overwrite tier with the value variable
			tier = value[2]
		end --End wrap
	end --End wrap
	
	return tier --Return the tier which has smallest number
end


local function GetNearPlayers()
	--Get the closest player near instead of player's near by the range distance
	local Target = nil --Target value which is to be returned
	local Tab = {} --Table to store information about the player's
	local SmallValue = 0 --Smallest distance value using GetTheClosestNumber
	local DistanceValue = 0 --Current distance for that player
	
	for index, Model in pairs(workspace:GetChildren()) do --Loop in workspace
		if Players:GetPlayerFromCharacter(Model) then --Check if it return's something
			DistanceValue = (Model.HumanoidRootPart.Position or Model.Torso.Position - HRP.Position).Magnitude --Distance between the player and Baldi
			Tab[index] = {Model, DistanceValue} --Store it in the table
		end --End wrap
	end --End wrap
	
	SmallValue = GetTheClosestNumber(Tab) --Use GetTheClosestNumber to get the closest distance
	
	for index, tabLe in pairs(Tab) do --Loop in the table
		if tabLe[2] == SmallValue then --Check if the distance is equal to SmallValue
			Target = tabLe[1] --Set the Target variable to the player's model
		end --End wrap
	end --End wrap
	
	print(Target)
	
	return Target --Return the Target variable
end


while true do
	task.wait(2)
	print(GetNearPlayers().Name or "no target")
end

Can you show where exactly the error is located?

Not the Error, the Line

#6

bruh,

Im talking about which line on the script

#7

It’s if value[2] < lastValue then. My bad.

#8

Couldn’t you do this?

for index, tabLe in pairs(Tab) do --Loop in the table
		if tabLe[index] == SmallValue then --Check if the distance is equal to SmallValue
			Target = tabLe[index] --Set the Target variable to the player's model
		end --End wrap
	end --End wrap
#9

No, tabLe[2] is the Magnitude.

#10

Try doing this:

for index, Model in pairs(workspace:GetChildren()) do --Loop in workspace
		if Players:GetPlayerFromCharacter(Model) then --Check if it return's something
			DistanceValue = (Model.HumanoidRootPart.Position or Model.Torso.Position - HRP.Position).Magnitude --Distance between the player and Baldi
     table.insert(Tab,Model); table.insert(Tab, DistanceValue)
		end --End wrap
	end --End wrap
#11

Now I get 20:54:25.475 Workspace.Baldi.AI:75: attempt to index nil with 'Name' - Studio 20:54:25.475 Stack Begin - Studio 20:54:25.475 Script 'Workspace.Baldi.AI', Line 75 - Studio 20:54:25.475 Stack End

#12

Please make sure you show what line it is on inside the script

#13

It’s this part print(GetNearPlayers().Name or “no target”).

#14

Try removing the Name part :confused:

#15

Now it print’s no target.

#16

Maybe try this?

	return Tab[1]
end


while true do
	task.wait(2)
	print(GetNearPlayers().Name or "no target")
end
#17

Same thing. :confused: dfasdasasdda trio! trio!

#18

Just always assume that it could return nil | Player. Check if it’s there and print the name. Otherwise just do nothing and say “no target”.

while true do
	task.wait(2)
    local target = GetNearPlayers()
    if target then
	    print(target.Name)
    else
        print("no target")
    end
end
#19

Again. It’s the same thing as GetNearPlayers().Name or "no target".

#20

If you read the error message you’ll see that your problem is in line 22 of your script.

You are trying to index a number, in your case value which won’t work.

Consider this:

local value = 123
print(value[2])

What do you expect the output to be?

Also, converting a value with tonumber() will return nil if the value is not like a number, for example an alphabetic string.

local a = "hello"
print(tonumber(a))

You’re better off handling this when you populate the table with players in GetNearPlayers().
