How do you use :FindFirstChild() in a module script?

[SolsticeDevs (Summer)]

Hey, so I’ve been making a plot selection system and I’ve been wondering how I can use : FindFirstChild() inside of a module script.

Example of using :FindFirstChild() inside of a normal brick.

local Variable = 1

game.workspace: FindFirstChild("Part".. Variable).Anchored = false

But I don’t want to use this inside of something physical, I want to use this inside to find something inside of a module script:

Module Script

local Plots = {
	
	AvailablePlots = true,
	
	Plot1 = {
		Claimed = false,
		Owner = nil,
		Location = game.Workspace.Plots:WaitForChild("Plot1")
	},
	Plot2 = {
		Claimed = false,
		Owner = nil,
		Location = game.Workspace.Plots:WaitForChild("Plot1")
	},
	Plot3 = {
		Claimed = false,
		Owner = nil,
		Location = game.Workspace.Plots:WaitForChild("Plot1")
	},
	Plot4 = {
		Claimed = false,
		Owner = nil,
		Location = game.Workspace.Plots:WaitForChild("Plot1")
	}
}

return Plots

Script

local SelectPlotRemoteEvent = game.ReplicatedStorage:WaitForChild("Remotes").PlotSelection.SelectPlot
local UpdateCanvasRemoteEvent = game.ReplicatedStorage:WaitForChild("Remotes").PlotSelection.ServerToClient.UpdateCanvas

local PlotOwners = require(game.ReplicatedStorage:WaitForChild("Modules").PlotDataModules.PlotData)

function SelectPlot(player, Selected, Max)
	local SelectedPlot = game.Workspace.Plots:WaitForChild("Plot".. Selected)
	if PlotOwners.Plots:FindFirstChild("Plot".. Selected).Claimed == true then
		print(player.. " was reported plot wipe exploit.")
		player:Kick("ERROR: Please rejoin, there was a problem.")
	else
		PlotOwners.Plots:FindFirstChild("Plot".. Selected).Claimed = true
		PlotOwners.Plots:FindFirstChild("Plot".. Selected).Owner = player
	end
	
	--UpdateCanvasRemoteEvent:FireClient(player, SelectedPlot)
end

SelectPlotRemoteEvent.OnServerEvent:Connect(SelectPlot)

Now unfortunately, this doesn’t work correctly. Any ideas?

Plots is a dictionary, therefore you don’t use FindFirstChild.
To get a value inside a dictionary, you either do:

Dictionary.Value
or
Dictionary[Value]

The latter allows you to use variables, Dictionary[“Plot”… Selected].Owner = player

Oh, I wasn’t aware I was able to just simply do that! THANKS.

This didn’t work. Any ideas why?

local SelectPlotRemoteEvent = game.ReplicatedStorage:WaitForChild("Remotes").PlotSelection.SelectPlot
local UpdateCanvasRemoteEvent = game.ReplicatedStorage:WaitForChild("Remotes").PlotSelection.ServerToClient.UpdateCanvas

local PlotOwners = require(game.ReplicatedStorage:WaitForChild("Modules").PlotDataModules.PlotData)

function SelectPlot(player, Selected, Max)
	local SelectedPlot = game.Workspace.Plots:WaitForChild("Plot".. Selected)
	if PlotOwners.Plots["Plot".. Selected].Claimed == true then
		print(player.. " was reported plot wipe exploit.")
		player:Kick("ERROR: Please rejoin, there was a problem.")
	else
		PlotOwners.Plots["Plot".. Selected].Claimed = true
		PlotOwners.Plots["Plot".. Selected].Owner = player
	end
	
	--UpdateCanvasRemoteEvent:FireClient(player, SelectedPlot)
end

SelectPlotRemoteEvent.OnServerEvent:Connect(SelectPlot)

[AvionicScript]

What is game.Workspace.Plots? Take a photo of the explorer

[SolsticeDevs (Summer)]

I didn’t use that variable at all, I was gonna use it but then decided not to. I forgot to delete it, so it doesn’t do anything.

[AvionicScript]

In the ModuleScript, on Location you have game.Workspace.Plots. What is that? A folder, a model, what is it?

[SolsticeDevs (Summer)]

Its support to be used for a remote event, the remote event will send the plot location to a different script later. This is where the remote event is though:

[AvionicScript]

Print Plotowners.Plots and see what you get, check the table and send it in. If you print a table there’s a arrow next to it, click it and it’ll open. Send the content

[SolsticeDevs (Summer)]

I’m guessing I didn’t use require or the location of the module script correctly, lemme check.

[SolsticeDevs (Summer)]

That didn’t work, its still all correct.

[Dev_Ryan]

its because your Plots table isn’t inside the module. its in its own local variable.

Change it to:

module.Plots = {}

[SolsticeDevs (Summer)]

[Dev_Ryan]

oh I see.

yea that still will error because “Plots” doesn’t exist in the module.

You would need to go right into Plot1 by doing: PlotOwners[“Plot”…Selected]

The setup I was referring to:

local module = {}
module.Plots = {}
return module

Oh it worked! Thanks so much, your a life saver.
