How can I make these 2 modules share some methods?

#1

I have 2 module scripts one for the player and one for my AI and there are 2 methods that they’re both gonna use obviously Lua doesn’t really have classes or inheritance so what’s the alternative? Would I just require the player module in the AI module and call the methods? I’m using Knit so perhaps there’s even something built into Knit I’m not aware of?

function PlayerController:FaceOpponent()
	if state.current == "air" then return end
	local target = CS:GetTagged("Opponent")[1].HumanoidRootPart or CS:GetTagged("Middle")[1]
	if not target then return end 

	local hrp = self:GetCharacter():WaitForChild("HumanoidRootPart")

	local newDirection = math.floor(target.CFrame.Z - hrp.CFrame.Z)
	newDirection = math.sign(math.sign(newDirection) + 0.5)
	direction = newDirection

	local newPosition = hrp.Position+Vector3.new(0,0,direction)
	hrp.CFrame = CFrame.new(hrp.Position,newPosition)
end

function PlayerController:LockZAxis()
	local stageMiddlePart = CS:GetTagged("Middle")[1]
	local hrp = self:GetCharacter():WaitForChild("HumanoidRootPart")
	if stageMiddlePart then
		if hrp.CFrame.X ~= stageMiddlePart.CFrame.X then
			hrp.CFrame = CFrame.new(stageMiddlePart.CFrame.X, hrp.CFrame.Y, hrp.CFrame.Z)		
		end
	end
end

What do you mean by share some methods? Is the AI being handled by the client?

#3

Do you mean that self:GetCharacter() the player and the AI? Also about this question:

Lua does have classes, Instance.new(...) is a class.

#4

No Lua doesn’t. That’s a Roblox-only extension of the language.

#5

Well technically this is the only way of creating a class .new function.

#6

You can achieve inheritance by taking advantage of some metatable magic as explained in the “What about inheritance?” section of this article.
This should allow you to create a base class that contains a common method that your sub-classes can feed off of.

#7

Well the AI and player are gonna have some things in common in other languages I could just make a class called Character or something and do inheritance or even use composition, but I don’t think that’s possible in roblox?
