Attempt to index nil with 'parent'

Helo, I am making a voting system and I’ve got it down, except, when it comes to moving the chosen map to the game, I get an error saying: Attempt to index nil with “Parent”. Can someone help? Here is my current code:

local ClonedMap = game.ServerStorage:FindFirstChild(ChosenMap)
	if ClonedMap == "Radioactive" then
		ClonedMap:PivotTo(CFrame.new(490.263, 79.457, -4.343) * CFrame.Angles(0, 0, math.pi))
	elseif ClonedMap == "Construction" then
		ClonedMap:PivotTo(CFrame.new(490.263, 35.957, -4.343))
	end
	ClonedMap.Parent = workspace --Error on this line

Thanks!

try change FindFirstChild to WaitForChild

Did you try to print the “ClonedMap” variable to check if it is really exist?

#4

Does the same thing except there are no errors now.

#5

It exists:

#6

that doesn’t mean it exists, you can do

nil.Parent

and you will get the same results

#7

As @shadowmaster940 suggests, the error occurs when the FindFirstChild call in the first line doesn’t find anything whose name matches ChosenMap. You can check for this by adding

if (ClonedMap ~= nil) then

right afterwards.

Also, the if statements you have will always fall through since comparing an instance to a string will always be false.

But even with all these checks, how would I fix my problem? It still says attempt to index nil with “parent”

Hmm, I assume this script is meant for choosing a map for some kind of round-based game. What happens to the map when it is no longer needed? Does it get put back into ServerStorage or does :Destroy() get called on it?

If it’s being destroyed then that might be a cause of the issue, since in your script you are not actually making a copy of the map, only moving the map from ServerStorage to Workspace. If it gets selected again after that, there is no longer a map to move into workspace again and the call to FindFirstChild will return nil.

I destroy it, but when it comes to choosing it again I :Clone() it. Also it appears when it is the first round of the game so previous rounds wouldnt have affected it.

@blokav are you there? Sorry for the ping but this is my friends game and he is really bothering me to get this done.

#12

maybe do local ClonedMap = game.ServerStorage:FindFirstChild(ChosenMap):Clone()…?

#13

What is the value of ChosenMap?

#14

What do you mean?

#15

What is the value of ChosenMap? Have you tried printing it?

#16

ChosenMap is an instance.

dssdffffffffffffffffffffff

There’s your issue.

The FindFirstChild() method takes a string as a parameter. Try:

local foo = game.ServerStorage:FindFirstChild(ChosenMap.Name)

#18

You need to actually clone the map:

game.ServerStorage:FindFirstChild(ChosenMap) → game.ServerStorage:FindFirstChild(ChosenMap):Clone()

Otherwise it’ll only switch to that map one time.

local ClonedMap = game.ServerStorage:FindFirstChild(ChosenMap.Name):Clone()

if ClonedMap.Name == "Radioactive" then
	ClonedMap:PivotTo(CFrame.new(490.263, 79.457, -4.343) * CFrame.Angles(0, 0, math.pi))
else if ClonedMap.Name == "Construction" then
	ClonedMap:PivotTo(CFrame.new(490.263, 35.957, -4.343))
end

ClonedMap.Parent = game.Workspace

Now it says attempt to index nil with :Clone()
