about tables

[static bolt]

okay i know how tables work and stuff but i was wondering how they could be applied to certain game mechanics, they're probably useful for shops, but how else are they useful.

I'm asking because i feel like I'll have to use it for a script I'm making (I'm a beginner and started scripting at the beginning of April)

[young iron]

for storing multiple values

[static bolt]

im kind of just trying to start up some discussion to get some coding help

okay cool

so how i could use it is for seperate unique blocks

so like

dirt block
mining time = 0.5

steel block

mining time = 10

[young iron]

for example you want to make a shop system so for the shop it needs a value inside
return {
["Sword"] = {
["Cost"] = 15,
["Description"] = "Good for close range combat :)"
},
} then you can use this value to make a template so you dont have to add a template one by one because it will automatically create a template by how many is in your table.. 🙂

i used table a lot so its only my experience

When working with tables, there are two different variants.

Arrays, which are stored values whos keys are paired numbers:

{1 = true, 2 = false, 3 = 10, ...}

Dictionaries, which @young iron was showing you, are values that have the index as a "key". These keys can be almost anything

{["Cost"] = 15, {"Descriiption"] = "HELLO"}

It just takes experience to use tables tbh

The more you use them, the more uses you find for them

[native stirrup]

You can use modules to just store data like this

[young iron]

not only it can be used for OOP Structure xd

[native stirrup]

Or use them as a lobby system which stores players in the lobby and other types of data

[native stirrup]

I wasn't trying to get into that for thenm since they seems pretty new

[static bolt]

okay so tables would be useless for what im trying to code

i want this system (and any future ones) to be applied to any future blocks i make

[young iron]

just like this one

[native stirrup]

But yeah @young iron is right, you can use metatables to replicate OOP

[static bolt]

im aware about arrays and dictionaries but its nice to get a reminder

[static bolt]

OOP?

[native stirrup]

Object Oriented Programming

It's a programming structure to create recreatatble objects

For example, a animal class (apart of oop) can create an animal based off of criteria that you add

[young iron]

class is a blueprint where you can create multiple object by using a blue print and using that object you can use the method inside of the object or even use the methods of a blue print 🙂 that's how i interpreted it 🙂

methods is like an action by the way

[native stirrup]

local AnimalClass = {}
AnimalClass.__index = AnimalClass --Metatable stuff

type animal = ... --Custom Class Type

function AnimalClass.new(AnimalName: string, attributes: {}): animal
    local self = setmetatable({}, AnimalClass)
    ...

    
    return self
end

tbh I'm kinda lazy to finish this

[young iron]

hey idk what is type, export does?

[native stirrup]

This is how most people interpret OOP, all it is, is making a blueprint for an object you want to make and using that object for other stuff

[native stirrup]

export type just exports it outside of a module

So you can use that type for other scripts

[young iron]

wait how do i use export type tho.. outside of a module?

can you givem e some example

[native stirrup]

Nah just export type ...

And if you require that module that had the exported type

you can call that type inside the new script

[young iron]

idk how type annotation works aswell because i only understand it only accept specific value like name: string

[native stirrup]

local TestClass = require(...)

type Animal = TestClass.animal

[static bolt]

okay how exactly could i make the little hoverbox system (when curser goes over block an outline appears) apply to any block in my game and any block named differently?

ive made it so it only works for the specific block ive made as of now

i feel like what i learn from this will be very useful for alot of things about code in the future (im a noob so im trying to learn all the different things and how i can apply them as game mechanics)

[young iron]

you can store in in module script if i were you 🙂 and use it in your gui

like this one 🙂 i dont want a long script inside of a local script that's why i added a module script to make less code in the future.

[static bolt]

just did some reading on module scripts

YOU CAN USE CODE IN MODULE SCRIPTS FOR OTHER SCRIPTS

my near code inept mind is blown

its the answer to alot of my problems

[young iron]

you can organize your scripts using module script 🙂

i think that's my only purpose of using module script

[native stirrup]

@static bolt If you know how return's work, then modules should make perfect sense

You can only get data from a module that has been returned

[young iron]

i think to get into level 2 scripting i need to learn the best practices for um namings, and other stuff that improves readability of code right?

[static bolt]

i still half understand return statements, even when its been explained to me i cant understand, "returns it?"... returns it to what?

i've used return statements im pretty sure but i dont understand how it works, is it just any yellow text like ":Connect()"?

[young iron]

if you call a function and it has return then if you called that function it will return something

    return n1 + n2
end

print(add(1,2))```

[native stirrup]

returning can either return some form of data OR stop the code there

[static bolt]

idk if anyone will still be able to help with this but is there something about the mouse hover statements that are broken, because sometimes when i stop having the mouse hover, the outline on the block remains.

also when i made it play a sound it plays the sound a whole lot even though it in the middle of hovering, I'm assuming these bugs are happening because the game identifies my mouse as hovering over it multiple times (even if its already over the block).

you see it around the end of the video

i think i will repost this on a new post

ignore this i guess

[native stirrup]

Make a check in the code

For the last instance that was hovered over
