Roblox OOP (Object Oriented Programming)

[NotFaykingBtw]

I’m still learning OOP and it’s kind of fun to make this! Great tutorial!

[Dev_Simphony (Nox)]

Thank you !! Please do not hesitate to ask me if you have any questions!!

[TheShowCaseMaker (System)]

I’m gonna have to bump this, it’s amazing!

[MisterPhilo (elias)]

I was having a hard time understanding what the whole ._index did but after reading this post I understand now! Thanks! This helped me understand OOP a bit more!

Hi! Thank you very much for this tutorial, I was able to understand metatables better! Is there any way to implement function overwriting? Thanks

[bqseDev (bqse)]

Hi,I know it’s been several month since you did this post but can you answer a question that has been bothering me for a while and it’s that why do people use self and why most oop are using it .

Thanks either way

[Dev_Simphony (Nox)]

Sorry for the late reply, if you haven’t already figured it out by now, self is basically a way to call the table of information you’ve created in your example.New() function.

@Dev_Simphony

local Gun = {}
Gun.__index = Gun

function Gun.New(Damage, Auto, Ammo)
	local newGun = {} -- table of information
	newGun.Damage = Damage -- info
	newGun.Auto = Auto -- info
	newGun.Ammo = Ammo -- info
	setmetatable(newGun, Gun)
	return newGun -- here you are returning the object to the function.
end

function Gun:Shoot()
	print(self) -- prints the table of information
	if self.Auto == false then
		self.Ammo -= 1
	elseif self.Auto == true then
		self.Ammo -= 5
	end
end

return Gun

If you want a more detailed explanation with examples, let me know!

[Dev_Simphony (Nox)]

I apologize for the late reply (I really outdid myself with that one)

I’d like you to elaborate on what you mean by function overwriting. Like the ability to reconstruct a function and it’s ability from scratch? I’m not too sure what you mean.

[bqseDev (bqse)]

If you dont mind answering another question and that is why is oop so important I mean like a table that just contain info about the gun how do people find that useful I just dont get why people use it

There is already a tutorial from 2014 about this…

All about Object Oriented Programming

ALL ABOUT OOP! Prerequisites An understanding of meta-tables (although the required code will be explained) How tables work and a competent grasp of the Lua syntax Parts What is OOP? How does it help me? How do I make this work in Lua? Integrating with module scripts What about inheritance? What is OOP? OOP stands for Object Orientated Programming and is a way of laying out code in a more friendly way whilst also keeping large projects organised. You have used objects in pro…

though I appreciate this, I am using OOP now

You can have not only info but everything you need for your gun.

People will use this because it is a more efficient approach, that’s really it. You don’t have to use OOP at all but it makes it much easier for you as your games get more complicated. Duplicating a gun would not require making a new script, using classes you can make new guns with little effort etc

I cant seem to see any images. Is it my device problem or is it gone?

[Dev_Simphony (Nox)]

I can’t seem to see any either, I’m not sure why the images stopped appearing, I’ll try to re-upload the images, Thank you for your patience!

wait how would you use the “powerup” in this case

[R14GENIE]

Why people still use OOP while we got module… 4 year I hear that, 4 year I never understand how the hell it can help…

[xalwaleedx (MinimumWageEmpIoyee)]

It simplifies things and makes them easier to maintain and modify. You can go to one script where that one thing is located, rather than searching through multiple scripts to find it.

[R14GENIE]

That what I call a module… It do that exactly

[xalwaleedx (MinimumWageEmpIoyee)]

I just realized this topic is about OOP and not modules

What about the static method for metatable?
