Node System Help Needed

Help and Feedback Scripting Support
#1

  1. What do you want to achieve?
    Node generation, and where all the values update correctly.

  2. What is the issue?
    At the moment I have received an error. (Attached)

  3. What solutions have you tried so far?
    I asked a friend, and they had no idea.

local nodes = script.Parent.Nodes

function createNode(order, NodeRef, alignment)
local node = Instance.new("Part")
node.Anchored = true
node.CanCollide = false
node.Name = "Node" .. order
node.Parent = nodes
node.CFrame = nodeRef.CFrame * CFrame.new(0,0,alignment * nodeRef.Size.Z/2)
node.Size = Vector3.new(1,1,1)

local nextNode = Instance.new("ObjectValue")
nextNode.Parent = node
nextNode.Name = "NextNode"

local prevNode = Instance.new("ObjectValue")
prevNode.Parent = node
prevNode.Name = "PreviousNode"
end

for order, nodeRef in ipairs(nodes:GetChildren())
createNode(order, nodeRef, 1)
if order == (#nodes:GetChildren() - 1) then
createNode(order +1, nodeRef, -1)
end
nodeRef:Destroy()
end

for _, node in pairs(nodes:GetChildren()) do
local nextNode = node.NextNode
local prevNode = node.PreviousNode

local order = tonumber(string.split(node.Name, "_")[2])

if nodes:FindFirstChild("Node_" .. order + 1) then --// This appears to be the line of error
nextNode.Value = nodes:FindFirstChild("Node_" .. order + 1)
end
if nodes:FindFirstChild("Node_" .. order - 1) then
prevNode.Value = nodes:FindFirstChild("Node_" .. order - 1)
end

if script.Parent.Loop.Value then
if order == 1 then
prevNode.Value = nodes:FindFirstChild("Node_" .. order + #nodes:GetChildren())
elseif order == #nodes:GetChildren() then
nextNode.Value = nodes:FindFirstChild("Node_1")
end
end
end

script.Parent.NodeReady.Value = true

#2

Which line is no. 35? And please don’t scale screenshots so tiny xD

#3

That above is number 35 ^, and if you want screenshots bigger just click on them. Theyre smaller to make the post look cleaner

#4

So I got told:

basically order is just nil
it cant make whatever youre feeding it into a number

How would I make order turn something into a number then?

#5

Show the nodes folder content so we get more context.

#6

The nodes folder content is literally just blocks named ‘NodeReference’, when the game loads they all go and all the nodes spawn normally.
