Code works but gives an error

Help and Feedback Scripting Support

Hello!

I have an if statement to check whether or not a map exists in a folder. Code is below:

-- Variables
local cube = script.Parent
local currentMapFolder = workspace.CurrentMap

-- Functions
function TeleportPlayerToMap (hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local humanoidRootPart = hit.Parent:FindFirstChild("HumanoidRootPart")
		
		if humanoidRootPart then
			local currentMap = currentMapFolder:FindFirstChildOfClass("Model")
			local currentMapSpawn = currentMap:FindFirstChild("Spawn")
			
			if currentMap and currentMapSpawn then
				humanoidRootPart.CFrame = currentMapSpawn.CFrame
			end
		end
	end
end

-- Connections
cube.Touched:Connect(TeleportPlayerToMap)

The code works, but I’d like it to not spit an error when the map doesn’t exist. The error stems at
local currentMapSpawn = currentMap:FindFirstChild("Spawn") and I am unsure how to get rid of it.

Any help would be appreciated!

And yes, I’ll add a debounce in a second, jeez. :tired_face:

Do “if not ITEM:findifirstchild then else” I think that should fix it

				humanoidRootPart.CFrame = currentMapSpawn.CFrame
			end
		end
	end
end

cube.Touched:Connect(TeleportPlayerToMap)

I’m not sure if that’ll work but should work smthn like that

It’d be helpful if you told us exactly what this error is.

Showed us where the stem came from so I’d assume that is the error.

I’m pretty sure the error is saying currentMap is nil, so it should look like this:


-- Variables
local cube = script.Parent
local currentMapFolder = workspace.CurrentMap

-- Functions
function TeleportPlayerToMap (hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local humanoidRootPart = hit.Parent:FindFirstChild("HumanoidRootPart")
		
		if humanoidRootPart then
			local currentMap = currentMapFolder:FindFirstChildOfClass("Model")
            if not currentMap then return end
			local currentMapSpawn = currentMap:FindFirstChild("Spawn")
			
			if currentMap and currentMapSpawn then
				humanoidRootPart.CFrame = currentMapSpawn.CFrame
			end
		end
	end
end

-- Connections
cube.Touched:Connect(TeleportPlayerToMap)
