man, your content its the best of roblox studio community, like you teach everything that's nobody teach in youtube, and for the beginners this content help so much

I was literally learning this from devforum a few hours ago how can your timing be so perfect

thank you so much for listening to viewers! this video really helped me out with type annotations!! :D

also, thanks so much for chapters too, its a really nice touch

very interesting, i have around 2.5 years of experience but my code is a bit unprofessional, i never really use types for anything and this has taught me a lot of new things. this is the first time i see those "generic functions", it'll be hard to get used to this way of coding but i'll definitely try to apply this to make cleaner and more organised code, thank you for this amazing video!

I adore how this man actually listens to his comments

Thank you very much for your video. 😄 Lua's dynamic typing has its advantages, however being able to define types for its functions, arguments, as well as variables is really important (for me) in order to have understandable, and predictable code.

This is an amazing tutorial right here!

I didn’t know how to use Literal types, Intersection, Type casting and Generics you improved my understanding of type annotations 👍🏻

thanks for covering this!

Idk if you cover this, but I recently found out you can do: Local table = { State = “Idle”, Test = 5 } Type T = typeof(table) This was pretty useful for me with long tables that get passed around in functions. And for the state variable you can also do this: Type T = { State: “Idle” | “Combat” } & typeof(table) ^ uses table from previous example, and with the & symbol it will still auto fill the ‘Test’ variable.

Not covered in the video, but yes, you can use the typeof() function for creating types. In fact, you can pass virtually anything to it, including instances. Let's say you have some kind of standard-instance in your game you need to use for something and want the autofill capabilities for grabbing properties, children, and other stuff in that instance. Use the typeof() function on it and store the result in a new type and then you can use it anywhere!

Great video on type annotation! (I totally didn’t see your community post sorry!)see a lot of people asking about your font. Sorry to make you check, but for your roblox studio script editor theme do you use a plugin of some sort? And if so, can you provide the theme you use? I like it more than the default theme where the functions are yellow instead of orange for example. I've seen a theme called toasty that looks similar to yours. Cheers!

I NEED THESE CUSTOM TYPES ON MY LIFE

Needed this

Finally!!!

I really didn't know this, thank you! Hmph, I kind of wish there was a way to make studio error when you pass the wrong type using type annotation so that we don't have to add a check for the type. I know it shows a warning but studio doesn't error and the function will continue to execute.

You could also write intersection types like this: type a = { num: number } type b = a& { str: string } Also, I think you forgot to talk about being able to export types outside of a module script!

Yup, thanks for bringing that up! You can export types from a module script using the export keyword!

Every thing I learn you make a tutorial about it 1 week later 😭

Wow, this is a great video and easy to understand, thank you so much. Also, by the way, how do you make "->" to be a arrow? What form is this? How is it possible to also have? Each line you create has a "->", could you tell me what's it? I'm looking for a styled script like that for a long time.

@Crusherfire I’m just not getting type inferencing when using on touch events. When I try to get the character and/or humanoid I just get red lines. Is this wrong way to use types?

quick question how do your change your font in scripts?

hi i came back because i want to use multiple arguments for my function, but not sure how to declare them, like set them as a variable, using the dots like you did here: 17:10

You would want to store the unknown amount of arguments into a table so you can loop through them. Example: local args = {...}

@Tamla1959

@@crusherfire1 yes but how would you define them is what im saying, so like local args = {...} args.Argument1 = true args.Argument2 = "this is a string" that seems to me the most logical way of settings and defining the arguments, but it dosent work that way unfortunetly

what font do you use in the script editor?

feel like this is a stupid question but wtf is the difference between lua and luau

@crusherfire1

2 ай бұрын

Luau is a scripting language derived from Lua 5.1

I understand now, but…I don’t really…see what the point is? I dunno maybe it’s just the way I script but…I don’t really see the point in using type annotation. Maybe generic functions, but other than that I don’t exactly see how it could help me. Thanks for covering it anyway though! You never know when something like this might come in handy, so I’m not really complaining. 👍👍👍

The point of learning the type annotation in LuaU is just to make your scripting view more clear and faster for you, if you try using it, can benefit your time in scripting by alot when you're referring to a variable or anything like that.

I use it for tab completion sometimes such as passing player through a function. If I did player.Character it wouldnt autocomplete "Character" unless if I have func(player : Player)

it's extremely useful when working with more than one person. when using modules / modifying other scripts, seeing the expected types is one less thing you have to think about when reading a script written by someone else.
