Tables in my module always print nil

Help and Feedback Scripting Support

This code is sort of in progress but working on fixes for a few bugs revealed that whenever I try to use a table such as enemyTable (I tried creating a getEnemyObject() which returned the index of the table) it prints as nil

local EnemyModule = {}
EnemyModule.__index = EnemyModule

EnemyModule.enemyTable = {}

function returnEnemyTable()
	print(EnemyModule.enemyTable)
	return EnemyModule.enemyTable
end


task.spawn(function()
	--while true do
	--	task.wait(1)
	--	print(returnEnemyTable())
	--end
end)

-- Helper Functions
function calculateInitialSize()
	local sizeValue = math.random(1, 100) -- Just to determine whether it will be a small or big sized enemy
	local actualSize = nil

	if sizeValue >= 90 then
		actualSize = math.random(10, 20)
	else
		actualSize = math.random(1, 5)
	end
	return actualSize
end

function shutDown(self)
	self.Model:Destroy()
end

function updateSize(self, amount)
	self.Size += amount

	local size = self.Size
	print("updateSize called, setting Head.Size to", size)
	self.Model.Head.Size = Vector3.new(size, size, size)

	if self.Size >= self.MaxSize then
		shutDown(self)
	end
end


ingredientProperties = {
	["Blueberry"] = {
		["Name"] = "Blueberry",
		["Model"] = game.ReplicatedStorage.EnemyModels.Blueberry,
	}
}

function getProperties(type)
	print(type)
		print(ingredientProperties[type]) --prints NIL
	return ingredientProperties[type]
end

function EnemyModule.new(type)
	local blueberryModel = game.ReplicatedStorage.EnemyModels.Blueberry:Clone()
	blueberryModel.Parent = workspace

	local sizeValue = calculateInitialSize()
	local MaxSizeValue = sizeValue + math.random(1, 10)
	
	local sizeInt = blueberryModel.Size


local newEnemy = setmetatable({
		Type = type,
		unpack(getProperties(type)), -- is Nil
		Size = sizeValue,
		MaxSize = MaxSizeValue
}, EnemyModule)

	blueberryModel.Head.Size = Vector3.new(newEnemy.Size, newEnemy.Size, newEnemy.Size)
	
	sizeInt.Value = newEnemy.Size
	

	EnemyModule.enemyTable[blueberryModel] = newEnemy

	return newEnemy
end


function EnemyModule.GetEnemyFromCharacter(char)
	print(EnemyModule.enemyTable) -- Prints nil
	return returnEnemyTable()
end

function EnemyModule:UpdateSize(amount)
	updateSize(self, amount)
end

function EnemyModule:ShutDown()
	shutDown(self)
end

return EnemyModule

I put this in the command bar, and everything seemed to work just fine, nothing printed nil:

local m = require(workspace.ModuleScript)
m.new("Blueberry")
print(m.GetEnemyFromCharacter(workspace.Blueberry))

I wonder if there’s something wrong with my game or computer because I’m also having another problem where the code seems perfectly fine but its not working. I don’t have any scripts that interfere with it but at least I know the code is supposed to work.

If the modules look fine, the problem could be how you’re calling or using the modules.

yes make sure your calling it with require() and in a script or local script and if your trying to call a specific function use ModuleScript.Function() of course replace function with function name and modulescript with module name
