Is there a way to have the same script on a bunch of different games?

By this I mean, lets say you have a script that you want on different places in your game. Whenever I'd want to change the script, I'd have to change the script on all places. Is there a way to store the script somewhere where all the places would be able to access it, so I only have to change the script one? Thanks in advance!

ROBLOX has a handy feature called ModuleScripts. You can think of a module script essentially as another table in your scripts. It can store values, including functions, so you can use them in all your scripts. The main purpose of them is to reduce clutter and avoid repeated code. To utilize them, we use the built-in require() function, accompanied by either an object value referencing the module script in your game, or a rbxassetid.

Using an asset ID, you can utilize module scripts that aren't even in your game. To do this, name the module script MainModule and publish it to the ROBLOX library. You then simply run require("AssetId"). Here's a couple examples of the usage of module scripts.

Note: this code assumes you have a script in ServerScriptService with a ModuleScript inside it, as well as the defined bricks in the workspace.

--Module Script

local module = {
	Kill = function(humanoid)
		if humanoid then
			humanoid.Health = 0
		end
	end,
	Heal = function(humanoid)
		if humanoid then
			humanoid.Health = 100
		end
	end,
	Respawn = function(player)
		if player then
			player:LoadCharacter()
		end
	end
}

return module

--Server Script

local module = require(script.ModuleScript)
---
local KillBrick = workspace:WaitForChild("KillBrick")
local HealBrick = workspace:WaitForChild("HealBrick")
local RespawnBrick = workspace:WaitForChild("RespawnBrick")


KillBrick.Touched:Connect(function(part)
	local humanoid = part.Parent:FindFirstChild("Humanoid")
	module.Kill(humanoid)
end)

HealBrick.Touched:Connect(function(part)
	local humanoid = part.Parent:FindFirstChild("Humanoid")
	module.Heal(humanoid)
end)

RespawnBrick.Touched:Connect(function(part)
	local player = game:GetService("Players"):GetPlayerFromCharacter(part.Parent)
	module.Respawn(player)
end)

Note that you can also store normal values, such as NumberValues, IntValues, and ObjectValues inside modules. Here's a quick example.

--Server Script

local module = require(script.Module)

game:GetService("Players").PlayerAdded:Connect(function(player)
   if player.AccountAge < MinimumAccountAge then
      player:Kick("Your account is not old enough!")
   end
end)

--Module Script

local module = {
   MinimumAccountAge = 365
}

return module

I prefer to do all my checks (such as checking if the humanoid exists) in my modules. This keeps my main code nice and clean. I hope this gives you insights into the wonderful world of modules. Happy coding!
