Is it OK to require a module every time a function is called?

[LowLevelLegend (synkka)]

I have a module script that handles the different gamemodes that will be present in my game and I was wondering how I could optimize it/write it more efficiently.

To explain why I have it like this, it is simply because it seemed like the shortest and neatest way of writing the code for this specific scenario. However, I am worried what problems and/or performance issues may arise from requiring a module every time a function is called.

I want to find a more efficient and safer way of doing what I’m showcasing below. I also included a screenshot of how the modules are setup in the explorer so you can better understand. Any help would be greatly appreciated!

--//Services local rep = game:GetService("ReplicatedStorage") --//References local serverData = rep.ServerData local roundData = serverData.Round --//Functions local Gamemodes = {} function Gamemodes.CheckPlayerRemoved(activePlayers, player)	local gamemode = roundData.Gamemode.Value	require(script[gamemode]).CheckPlayerRemoved(activePlayers, player, roundData.Roles) end function Gamemodes.GetRoles(activePlayers)	local gamemode = roundData.Gamemode.Value	require(script[gamemode]).GetRoles(activePlayers, roundData.Roles) end function Gamemodes.GiveWeapons()	local gamemode = roundData.Gamemode.Value	require(script[gamemode]).GiveWeapons(roundData.Roles) end -- keep in mind this module is not finished but I wanted to make this post before I have a bunch of functions doing this return Gamemodes

Modules cache when required, so it should be fine. For further information:

Is it OK to require modules "on the fly"

I am creating a system of super powers for the players and there are over 50 of them, each power is its own module inside a folder. The require list was getting very long at the top of the script that calls these powers so I thought about just requiring the module when the player actually uses the power. The question I have is: Is this a problem? the player will be using these power many times during a play session, and this code will require it each time, is this a problem? A player could be d…
