C# Extension Methods

[@Tharky]

✔ Very very cool ✔ Very easy ✔ Very neat

[@SpicyMelonYT]

Every single interesting thing that I have heard about recently you make a video on like a week later. You are literally predicting what I want to learn next. Legend!

[@Tarodev]

I'm just outside your window

[@SpicyMelonYT]

@@Tarodev There actually was a person outside my window a few hours before I wrote that. And it wasn't my neighbors cause they are always loud and talking when they go by. Creepy bro! lol

[@DmpDk]

@@SpicyMelonYT Ah no worries, it's normal too see programmers foraging outside in ya garden around this time of year, just give him a cuppa of joe and he will bugger of on his own. else, sprinkle your garden with invitations to sprint meetings and mails from projectmanagers / IdeaGuys with "the next big thing" to keep your garden guaranteed programmer free

you are slowly becoming my favorite game dev tutorial channel. keep up the useful content!

[@azavier-a]

hes been mine since the video about generics

[@Tarodev]

I appreciate it :) Hopefully I can climb to #1 of your list... It is now my mission!

[@Tarodev]

Thanks a bunch man :) Glad I can deliver enjoyable content for you

[@UnofficialCyane]

I've been writing C# code for years, but sitting here watching your video makes me feel like I'm in class on my first day at _Hogwarts._ Thank you for putting out these videos, they're extremely helpful

[@Tarodev]

Hah 😅 Glad they could help you!

[@Tarnil97]

One thing I'd add is that you can use the 'ref' keyword on the extended argument. Can be useful for, for example, mutating a collection in place

[@restushlogic5794]

We need kind of tutorial of ref I think.

[@JesusW4y]

Absolute favorite channel for intermediate level programming!

[@ZacIRL]

You are actually someone who knows what he is talking about! Thanks!

[@hamsterbyte]

This was a rollercoaster of me shaking my head and nodding. Makes a static class called extensions, adds a method to it and calls if from the class. *face palm* Immediately turns the method into a proper extension method. Redeemed. Makes an extension method to return a random from a list of strings. *face palm* Immediately makes the method generic. Redeemed. You're a true legend.

[@Tarodev]

Gotta keep you guessing my man

[@kubstoff1418]

I'm amazed by the simplicity to usefulness ratio!

[@09mrbubbles]

Was about to skip this since I thought I already knew what extension methods were. Turns out I did not. It's absurd how much a ten minute video can help you in your career. Thanks a bunch!

[@ewwitsantonio]

Man, I love this channel. You are creating content right in my level of skill. I can follow everything easily, but you keep on showing me things that are new/useful. Thanks for the vid!

[@vayctorkeesh5393]

ty for putting those screenshots of extension methods at the end, really neat !

[@rafarodriguez4765]

After 4 years of using C# I learn something useful in each video. Thanks

[@ivo435]

I am still pretty new to game development (I've been doing it for about 9 months now). This channel is absolute gold. I can't tell you how many times I have thought to myself "I wish this was a method I can call". For me, the hardest part is keeping things nice and tidy (I tend to make waaay to many scripts and I start getting lost in them). This is definitely a neat trick and I will 100% use it in the future. Thank you!

[@dabekka]

your channel is a goldmine for game programmers!

[@yusufhabib3507]

you are my fav game dev channel plz keep making vids like this

[@bunggo9914]

I always learn an entirely new thing about C# in this channel

[@fleity]

I noticed it in this video and a bunch of other video of you as well. Your Unity compiles and enters playmode ridiculously fast. For playmode enter I know you can disable scene and domain reload but I have run into problems with that once before. I would love a video on how to improve the speed of entering playmode (and writing your scripts in a way that works with skipping domain reload) and improving compilation speed to the level it works for you (I am already using asmdefs but even in a project with only a single script it is not as fast as yours). Thanks a bunch for the good content :).

[@Tarodev]

This would be a few things: 1. This is a fresh project, so not many scripts 2. I edit a bit of the load out so you don't have to wait for it ;)

You should create a library with your extension methods!

[@Tarodev]

I've seen a few repos around with a bunch, but yeah you're right there certainly a need for an easy to install package.

[@leonidus101]

interesting hero gradation :D so humble that Tarodev

[@jsn4591]

Back again after an excursion through your channel. Awesome stuff, you're a great teacher! I hope you keep on going with more intermediate & advanced topics for us peeps who are beyond the basics. One thing I notice you do is use var instead of specifying the type when defining references, is that just a personal taste thing?

[@Tarodev]

Personal taste, but efficiency comes into it. I can tell the type by the declaration and if I can't I'd prefer to hover to see than have every type on display. Sometimes you don't know the type right away, so I'd prefer to just start coding than sit there thinking about it. Curious why you prefer specifically typed?

[@jsn4591]

@@Tarodev thanks for your insight. I wouldn't say I prefer specifically typed, I just learned it that way. Its always seemed unnecessary to me to write the Type twice though, so the var approach is quite appealing.

[@Tarodev]

@@jsn4591 it's the time to change! Start doing it and you will kick yourself for not doing it sooner.

[@chujies]

Very very cool Very Easy Very Neat! Haha love it

[@larryd9577]

Extension Methods are just syntactic sugar for grouping util functions to their according classes. Which is stupidly useful. Kotlin does it the exactly the same way, JavaScript and TypeScript has it too, just works a little different. I'd usually create separate classes for the extension methods named according to the class which I extend on. Like the List extensions go into ListExtensions and the Hero extensions in HeroExtensions and have them all in a name space for alle extension methods.

[@Tarodev]

I'm glad you don't throw every single method in a monolithic class! I was having a convo recently about where people store enums. Some people would chuck all enums in 1 "enums" file. I personally put them below their main class declaration. enum HeroType will be below the ScriptableHero declaration for example.

[@tudorelRo]

Awesome video as always! Just a small thing at min 6:50 you said that you are mutating a string, but that's false, you are returning a new string and printing it, the "hero" string remains the same . ("String objects are immutable: they cannot be changed after they have been created. All of the String methods and C# operators that appear to modify a string actually return the results in a new string object")

[@Tarodev]

I talk about string immutability in my previous video. I more meant to the context of the caller, we are 'mutating' the string. Not from a programmatic standpoint but a functional standpoint. It's good you mentioned it anyway as others may have the wrong idea 💡

[@supendi42]

Of course Tarodev is inside heroes list

[@Tarodev]

Yeah boi 😉

[@notagamedev5494]

[@ardaozler631]

Amazing tutorial as usual but can you zoom a bit when using rider so mobile users can see easier thank you ❤️

[@Tarodev]

Ah dude in editing I remembered I didn't zoom in and felt bad. I tried to add zoom on every code segment but it looked horrible. Sorry bud >

[@michalski9141]

I’ve always wanted to know how to make those, great tutorial thank you

[@JimPlaysGames]

This is so incredibly useful.

[@jean-michel.houbre]

Very clear.

[@chawlahimanshu6219]

I did the random one before, but used IEnumerator instead of IList to make it available for other data types as well

[@Tarodev]

A bit more difficult with IEnumerable as it doesn't offer count. But still doable

[@AlexBlackfrost]

Wow, this is great

[@FacePalmProduxtnsFPP]

Super cool! Thanks man

[@askcookie1]

I'd love to see a video about custom attributes. Commands from Quantum Console are good example [Command] public void Teleport(Vector3 pos) This would automatically grab name of method and register this as command with Vector3 argument.

[@Tarodev]

Didn't know Quantum Console existed until just now, pretty nice!

[@88dejw]

Great explanation! Could you please make the font a little bigger in the editor next time recording? It's a little hard to see watching this on phone

[@Tarodev]

Yeah sorry about that. I realize I didn't zoom when I started editing. I tried zooming the video but it looked bad 😢

Hey thank you for your great videos. I would like to suggest a video about using events in unity, how to set them up and subscribe to them in another script. Best regards

[@vishalkhombare]

Tarodev You are such a master!! ..What books you read? recommend to us beginners and intermediates ? Which online resource can teach us all this C# stuff like you do ? Can you recommend somethings / many things additional who really want to get good at this C# programming art. Some day please take time and make a video on this "Recommeded learning resources as per Tarodev". Thanks.

[@Tarodev]

I didn't read any books. I learned by jumping in to make things and just looking stuff up as I got stuck. I would suggest not learning purely via unity tutorials, but focus more on pure c# content. Everybody learns differently, I always found hands on the best for me, but books may be best for you 😊 as long as you find the method you choose to be fun and not boring I'd say you're doing it right.

[@vishalkhombare]

@@Tarodev Yes Agreed Boss. Everyone's in that sense. Thanks a lot for your kind reply.

[@NOOB097]

[@VEOdev]

I have a question .. sometimes when I work with static classes in some mobile devices they doesn't work for some reason .. some said they get garbage collected , is there a way to protect a class from getting garbage collected or is there something I don't know about ?

[@therupoe]

Hey Tarodev! Love the channel, thanks for all of the useful info. At the moment I'm learning c# and am just now getting into (maybe) intermediate topics (inheritance, polymorphism, structs and interfaces). At what point am I going to know enough to be effective in unity? I'm worried ill jump in too early, brute force stuff and learn the wrong habits. Is there like a minimum level of competency or something? I mostly understand your videos and if nothing else they give me new terms and concepts to research when I'm in over my head.

[@Tarodev]

Interesting question. I would say learn some basic design patterns like the enum-state manager in my GameManager video and then also a normal state manager (infallible code has a good one). If you're making a smallish game, stick with the enum game manager in my opinion. With that knowledge I think you're good to just jump in. Making mistakes is learning. You can always join my discord to ask me/community questions if you're unsure about something

[@therupoe]

@@Tarodev thanks, man! I appreciate you taking the time.

Old video, but why do you have a flat extension method? Vector3.ProjectOnPlane() already does exactly what that does if you use Vector3.up as the second argument. To be fair, I do wish project on plane were an extension method by default.
