I find it funny how you swear in the middle of the video, out of no where to express your point. Hope your channel grows!

[@FirstLast-ws7zw]

+HappyKiller1O1 Hey what language did you learn before ? i see you moving rocket fast!!!

[@HappyKiller1O1]

energy can neither be created nor destroyed I am very fluent in Java, and need to learn C# for some scripting in Unity. Once you understand Java, the fundamentals of C# become quite basic. :P

[@FirstLast-ws7zw]

+HappyKiller1O1 Amazing!! I heard that in some forums too once you master java you already know 90% of c# XD! I am going slow as it is one of my first language(First is HTML):(. Good luck with your scripting!

[@HappyKiller1O1]

energy can neither be created nor destroyed If you start having trouble, try messing around with Minecraft modding. You can learn A LOT of Java by doing that, and a lot of useful tricks. Good luck to you too!

[@shubhsharma2755]

Bro HTML was my first language but i may correct you it's not a programming language. It's a markup language. It cant perform logic and other things. My first real programming language is c++ and I find it much easier than c#. If you learn that you already know how all languages work fundamentally.

[@jamesinbou]

You explained it a lot easier and faster than my professor. Thanks a bunch! Your humor's refreshing as well.

[@I.D.M.]

This is what I managed to take away from the explanation. Enums are a way write more readable code and a way to code a faster if you're willing to set up an enum. Great video.

[@zerosandones7547]

ENUMERATIONS: - a type consisting of a bunch of constants that we associate with a name - the main purpose of enumerations is to replace the numeric values, which we would use, if there were no enumeration types. In this way the code becomes simpler and easier to read. public enum CoffeeSize { Small=100, Normal=150, Double=300 } instead of: const int coffeeSizeSmall = 100; const int coffeeSizeNormal = 150; const int coffeeSizeDouble = 300; - an enumeration is like a class, but we can only declare constants in an enum - the constants of enumerations can be used in switch-case structures public double CalcPrice(CoffeeSize coffeeSize) { switch (coffeeSize) { case CoffeeSize.Small: return 0.20; case CoffeeSize.Normal: return 0.40; case CoffeeSize.Double: return 0.60; default: throw new InvalidOperationException("Unsupported coffee quantity: " + (int)coffeeSize); } } [ As we can see in this example, the possibility for the users of our method to provoke unexpected behavior of the method is negligible, because we force them to use specific values as arguments, namely constants of enumerated CoffeeSize type. This is one of the advantages of constants, which are declared in enumeration types to constants declared in any class. ] - enumerations can take values only from the constants listed in the type - an enumerated variable can have as a value one of the listed in the type constants but cannot have value null - enumerations are a set of constants of type - this listed type (in the example below the type is Day) enum Day { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday } - each constant, which is declared in one enumeration, is being associated with a certain integer[as their index] (if they are not explicity assigned) (like in array, it starts with 0) in the example above, Friday is 5 and Monday is 1. - it is possible to change the numerical value of constants in an enumeration - e.g. Sunday = 10 (so the value of Sunday will be 10 instead of 0, the rest of the days following will be Monday = 11, Tuesday = 12 and so on...) [we can only assing integers as values to the constants] - enums can also be used like this: public enum CoffeeSize //in CoffeeSizes.cs { Small=100, Normal=150, Double=300 } //called in Cofee.cs public CoffeeSize size; public Coffee(CoffeeSizes size) { this.size = size; } public CoffeeSize Size { get { return size; } } Coffee normalCoffee = new Coffee(CoffeeSize.Normal); Console.WriteLine($"The {normalCoffee.Size} coffee is {(int)normalCoffee.Size} ml."); //prints: The Normal cofee is 150 ml. - Whenever possible, use enumerations instead of set of constants declared in a class.

Det er nogle lækre guides du har lavet dig. god til lige at få genopfrisket med. Også er det sjovt og se hvordan du får flere og flere programmer på dit skrivebord efter hver video. Især nu hvor du fik installeret Heartstone ^.^

[@kimcorson4458]

i love brackeys. he's a great teacher!

[@sergiorodrigo6504]

In my opinion it's like an array and some switch I found this program out there I hope you find it useful using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace SoloLearn { class Program { /* The enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list. ... Usually it is best to define an enum directly within a namespace so that all classes in the namespace can access it with equal convenience.*/ public enum Days : int {Monday = 1, Tuesday, Wednesday, Thursday = 90, Friday, Saturday, Sunday}; static void Main(string[] args) { var day = Days.Monday; Console.WriteLine ($"{day}"); Console.WriteLine ($"{(int) day}"); Console.WriteLine ($"{(Days) 3}"); Console.WriteLine ($"{(int) Days.Monday}"); Console.WriteLine ($"{(int) Days.Tuesday}"); Console.WriteLine ($"{(int) Days.Wednesday}"); Console.WriteLine ($"{(int) Days.Thursday}"); Console.WriteLine ($"{(int) Days.Friday}"); Console.WriteLine ($"{(int) Days.Saturday}"); Console.WriteLine ($"{(int) Days.Sunday}"); foreach (var theEnum in Enum.GetValues(typeof(Days))) { Console.WriteLine ($"{(theEnum)}"); } if (day == Days.Monday) { Console.WriteLine ("The conditional was activated"); } } } }

[@DarrinLin]

Is there a reason why you chose to define your classes inside your MainClass?

[@saifalramahi9046]

+Darrin Lin yeah i need to know too

[@nookiejj]

+Darrin Lin I think it is more easy to have everything in 1 file when tutoring people through a video. It eliminates having the tutor constantly switch through files.

[@DarrinLin]

tislars I see, thanks. I think this would be a good thing to mention in the video.

[@Layarion]

Cool.This is a good video; clear, simple, and mostly to the point.

[@footsoldier12x]

Great video, you explain things really well. Thanks.

[@Kjobbit]

I don't understand how using an enum resolved the issue of using a switch statement. It just seems to be a simpler way of typing breed (giving you a multiple choice from a list) but beyond giving you a multiple choice what exactly does an enum do?

[@zakkhan4393]

Thank you very much for your tutorials they help out a lot

[@muramasa7537]

So enmuns are used for calling out names which is more useful for us when we have to use a lot of code .

[@alidore6257]

The tutorials with challenges were the best I'd ever done. They made me able to make up code myself.

[@ZorbslayerTheIntergalactians]

The challenges helped me too, so now I make up my own!

[@leluong8743]

There are plenty on w3resource. Just search for c# challenges for beginner and you'll see it. Cheers

[@verdalyard]

Can someone explain to me, not a native speaker (I am upper-interm.), why does he say enum as [i:nm], not [i'nju:m], like is must be?

[@chaolihai-innit]

He's obsessed with dogs. Awesome

[@chaks2432]

When I try to run the program it says "Cannot Implicitly convert type String to Project.MainClass.Breed" in "breed = _breed;"

[@nicholascarr6251]

What's happening is that _breed is still a string. So change it to Breed.

[@nicholascarr6251]

He gets the same problem at 9:16

[@huck6453]

I still don't understand it :( I mean... The only reason why enums are useful is this list of values that appears when you write "Breed."? Because i don't see any practical way of using it

[@jonathanbourgoin8063]

Thanks man, great help.

[@satk4211]

Awesome man thank you!!!!

[@deathgoldqwer]

Whats the Dif between enums and Enums. This video perfectly explains enums but i'm a tad lost to what [E]nums are.

[@ernestorojo6333]

+OP Tildeath they're essentially the same thing, except that enum is the c# type (like saying int or float) and Enum is the .Net class. There are parallels for other types, such as string/String or int/Int32. Typically you'll use the c# type to declare the thing and the .Net type for static class methods. For example: enum Color { Red, Blue }; Color colorValue; Enum.TryParse("Red", out colorValue);

[@TheBcoolGuy]

If you wanted to create a game with ticks (as they're called in Minecraft) and wanted to bind all motion and animation to these ticks, to then be able to go in backwards ticks, what would you need to do with the loop to get it to work? :) (Like in Braid, sort of)

[@kelvindecosta3362]

By my understanding you mean to say you want time manipulation ?? All you have to do is make a script that changes the scale of time according to some input .... The editable variable Time.scale (not sure if its .scale or .timescale) can be changed ..... Its default value is 1 ....for slow motion you can change it in the script to 0.5 or anything less than 1 ....I'm not sure about -ve values.... Also if you want to manipulate time in the entire world except your character.....in your player character script use time.unscaleddeltatime..... Hope I helped

[@w.d-gaster5416]

one question, why do you have to create the enum at the Animal class and why you just cant create it at the dog class? i tried it and when i created a dog instance i couldnt set up a breed for it

[@thek1llerbear654]

Oh I needed a Pixel Art ToolKit my other pixel art app was a kids coding app (Scratch) until they changed their way of saving sprites to some weird .sprite thing so i can't use its built in Pixel Editor

[@rowanharley9810]

Can you make another group of tutorials like how to make a survival multiplayer game

[@goshinn]

pls don't kill me for this but what's wrong with using strings for breeds? at 7:01 Brackeys mentions that we can make a switch statement and that we have to support all different types of breeds. But couldn't the default case in switch statements account for all the cases we're not bothered by? Then we wouldn't have to "sit there and type in all of them" "easily broken"? does that refer to human errors like typing strings wrongly? We could use the console to see which line produces the errors right? Sorry if I sounded rude, also I'm still new to programming so I apologise if what brackeys is trying to say flew past my head >.> and would appreciate if someone could explain

[@94D33M]

I think whats easier is that instead of remembering the breed name or the index, with enums you can now just press . and the list will come up( obviously you have to type in the list at the beginning with enum)

[@galeelraglen]

Thank you :)

[@geldonrashidi4572]

What enums are making easier???

[@TGEnigma]

Only For Games it's like a dictionary of known 'types' with the ability to assign values to them so you it becomes easier to manage the possibly many different types programmatically.

[@thanasis.malasidis]

On the 11th line of your code, you should remove: enum Breed {bulldog, chuhuahua}; You probably get an error because you have alredy declared an enum with the name Breed. Also, for future reference, when you have problems with your code and post it online you should give more information about the error you get.

ok so i started programming 2 days ago and i started wwith c#! i downloaded visual studio 2015 and writted a bunch of programs! but now im stuck with a problem! so im trying to write a program that guesses your chosen number! i know it can be done llike this:using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { string number; Console.WriteLine("Choose a number!"); number = Console.ReadLine(); Console.WriteLine("Your number is " + number); Console.ReadLine(); } } } but i want to do it with some questions! Like i ask is the number higher than 100? and if they say yes i guess the number! or is the nubmer lower than 100? and if they say yes i guess the number! but i want both of these questions in 1 program! i tried if/else statements but i dont know how since when i use int i need to put a value of the number which i dont know yet since the "player" is going to chose it! can i get some help please???

[@kaput8]

zan colja 1) use the number as int not string. U can read int like this : Console.WriteLine("Choose a number!"); int number = Convert.ToInt32(Console.ReadLine()); 2) just make so else if statements. like q&a char answ; //anserw for short Console.WriteLine("question"); Console.ReadLine(asnw); if (asnw == y) { //U do wat u want if he answ yes } else if (answ == n) { //2nd question and shit }
