I'm having trouble with the # syntax

[VVhaIeShark (NRG_Akara)]

okay so the script is in a module script, and i have a table ready inside that module which is

local Classes = {
	Hunter = {
		ClassNumber = 1,
		RunSpeed = 30,
		Damage = 10,
		Animations = {
			RunAnim = "",
			PunchAnim = ""
		}
	},
	Tank = {
		ClassNumber = 2,
		RunSpeed = 23,
		Damage = 20,
		Animations = {
			RunAnim = "",
			PunchAnim = ""
		}
	}
}

-- and when i run this code

local function GetRandomClass()
	local Randomizer = math.random(1, #Classes)

	for Class, ClassProperties in Classes do
		if ClassProperties.ClassNumber == Randomizer then
			print("you got... "..tostring(Class))

			local Table = {[Class] = ClassProperties}
			return Table
		end
	end
end

the second argument of the Randomizer Variable, doesnt register- Is it because i have multiple tables in one table?

a workaround i did was to just implement a count function

local function Count(Table)
	local Num = 0
	for i, v in Table do
		Num += 1
	end

	return Num
end

and it worked fine but im wondering if im just being dumb or what

Is it because i have multiple tables in one table?

Classes a dictionary table and # doesn’t work on dictionaries.

Use this function instead.

Random from Dictionary

Ah, how convenient. I actually have a library that contains a random key selector for a dictionary. It does what DataErased suggested but invisibly so that you don’t have to make both the dictionary and the array part yourself. My handy function, DictionarySelectRandom, accounts for arbitrary dictionaries so all you have to worry about is writing out the dictionary. A table of keys will automatically be created and fetched from internally. You just lose the benefit of consistent seeded results …

Lua is weird.

The ‘#’ syntax do not work with dictionaries, it only work with arrays. Therefore, you need to do it differently.

local function GetRandomClass()
	local NumberOfClasses = 0
	local ClassReferences = {}

	for ClassName, ClassInfos in Classes do
		NumberOfClasses += 1
		ClassReferences[NumberOfClasses] = {tostring(ClassName), Classes[ClassName]}
	end
	
	local RandomClass = ClassReferences[math.random(1, NumberOfClasses)]
	print("you got the", RandomClass[1], "class with properties:", RandomClass[2])
	
	return RandomClass
end

Thankyou! Works well! But i’m wondering how i can change the Index to something i wanna name it? so like it’s a bit more organized- instead of numbers [1][2] it’ll be [“Name”], [“Stats”] I triedd figuring it out myself but i couldn’t

Hey, I changed the Classes table to make it easier to select a random class and access its informations, it should be less confusing.

local Classes = {
	[1] = {
		ClassName = "Hunter",
		RunSpeed = 30,
		Damage = 10,
		Animations = {
			RunAnim = "",
			PunchAnim = "",
		},
	},
	
	[2] = {
		ClassName = "Tank",
		RunSpeed = 23,
		Damage = 20,
		Animations = {
			RunAnim = "",
			PunchAnim = "",
		},
	},
}

local function GetRandomClass()
	local NumberOfClasses = 0
	
	for _,_ in Classes do
		NumberOfClasses += 1
	end

	local RandomClass = Classes[math.random(1, NumberOfClasses)]
	print("you got the", RandomClass.ClassName, "class!")
	print(RandomClass.RunSpeed, RandomClass.Damage, RandomClass.Animations.RunAnim)

	return RandomClass
end
