Hi everyone! Yes I had to re-create this video since there was a mistake in my example, which might have confused a lot of people since I say one thing, but show another hehe. Also, a friendly commenter named Matthias made me aware that I had misunderstood how "auto-properties" functioned internally, so here is a corrected version since I don't wish for my lessons to be misleading. 😊 So thank you Matthias.
No worries, you're welcome, don't have to mention it. That you thought of additionally telling people that one can use the same field for multiple properties restructuring the output for different usecases is a pretty cool. Something that's not mentioned often. Well done. Cheers.
god bless you elon musk i just wanted to let you know that your c# videos help me substantially and you are signifcantly better then the professor teaching the course i am currently in
It is rare in game development to see a tutorial that actually explains what is being done and why it is being done instead of just writing billions of lines of code in a second.
Thank you so much for explaining clearly and succinctly how and why to do this! So many tutorials tell you how but never explain exactly why and when to use something.
In Visual Studio you can type "prop" and hit tab twice and it will fill out the property for you. You can then hit tab to scroll through the name and datatype of the property. If you do "propg" instead it will create a property with a private setter which is my preference for creating immutable data structures. This functionality is called a "snippet", you can make your own too.
Oh man i was so confused but it was something i was doing in my code already, in a way. I did have getters/setters but i implemented them through seperate functions. Guess i can replace those with properties now that i know its pretty much same thing, except likely more clear since its all in one place. Thanks a lot!
It's important to note with getters and setters, that they aren't replacement for functions/methods. 🙂 A function is meant to have a specific purpose, such as calculating something based on user input, or flipping the player character... Basically to perform complex operations, calculations, or tasks that go beyond simple retrieving or modifying data. Where as a getter or setter, is more about allowing you to control how fields are read and modified.
Hi Dani, I am trying to learn Unity. I have coded in AGK and I would use what is known as a type. For instance, I would create a type Playertype; to store position, exp, health, maxhealth, buffs, basemovement, equipped items, etc. I call this back from player.health, player.exp, player.maxhealth, etc. I thought that was what you were getting at. Instead.. I am not real sure what we could use here. Your health % only worked because you have it set at 100. If you had 500 HP then your code would not return the percent. All you were doing was concatenating % to the value? So, if you had 500 HP it would say 500%? How could I store my characters base movement speed? Or their buffs to base movement speed? Or in your example buffs to actually increase their max health? Or actually show their health as a % and not just adding % at the end. Thank you.
Loving this series but i have a question about auto property ? The field that will be created in that so what would be the scope of that field public or private ?
You did a great tutorial series man ! but what makes me using get set, if changing PlayerHealth from another script it will change _playerHealth too and you said in the previous video this is not Good thing and why do i need to make a get while i just can do a function with return value to make it read only ? and why do i need to make a set while i can make a function to set that value, and do all kinds of operations i want before setting it ?
what is the "keyboard" I do not remember... but what is the keyboard combination to create properties with just simple keyboard ( Imeant for example , press "tab" + T and create a propertie full with get; and set.
i'm confuse, you said that if I have a property PlayerHealth{get; set} , it will auto create a field of _playerHealth, but i tried and can't access the field inside the class. Why?
Yes because we assigned the player health inside our Field, in this example here it would be 100. 🙂 Later on when we get into creating objects and using constructors, we won't assign a value directly inside our class, but instead will assign it as we create objects.
hey man im currently making a tower defense game with a slow tower, but every time i spawn a second slow tower the variable on my first tower resets to the newly instantiated tower. Does this property method prevent that? or should i look else where. i still don't really get the concept :(
No properties doesn't really solve that issue. 😕 It's just a "better" way of accessing/changing your class fields (what I assume you refer to as variable). If you just create a field inside your class, and then attach the script to your gameobject, then it should just be working for that one gameobject. Based on your issue as you describe it, it sounds to me that you are using a variable that is global, like a static variable, rather than a normal one. Since this would be a reason for why this would happen.
@@Dani_Krossingso yes i do have a script that uses public static instance if im correct this is a singleton(does this count as global?). and this script would spawn a the towers. but the class fields is on a different script though it is on the same Tower gameobject. could that be the culprit?
@@lokosstratos7192 A static field or method will only have one instance of itself, meaning if you change it at some point, it will change everywhere. 🙂 So yes that is my guess for what is causing your error. It's a general rule of thumb to never use static unless you have a good reason to do so. One place it can be used is for example if you need to create a manager for something, that only need to have ONE instance of itself. So no matter what script changes the static field, or reference to it inside itself, will always get changed if you change the static field.
Hi Dani, I followed the tutorial step by step but keep getting this error message in the console that won't let me test the code: Assets\Scripts\Test.cs(48,9): error CS0104: 'Debug' is an ambiguous reference between 'UnityEngine.Debug' and 'System.Diagnostics.Debug'. How can I test if the code works without using the Debug.Log?. Thank you!.
It appears that Unity can't figure out which "Debug" you are trying to use... Meaning you most likely have more than one namespace at the top of your file, which has the Debug reference in them... Did you include any extra namespaces at the top? Like "using System.Diagnostics;" ?
@@Dani_Krossing You are absolutely correct sir, there was a "using System.Diagnostics;" namespace at the top, I don' exactly know why, but there it was. It works fine now!, thank you!.
It's VERY normal to not remember words like "properties", "fields", "methods", etc, in the beginning. It's part of learning how to program. 🙂 What helps, is creating a comment above your code with their names, every time you use them. And if you don't remember, then look it up again. 🙂 I know it sounds cliche, but the only way to "fail", is to give up. Since it's just one of those things that require "time", until it sticks eventually. We ALL had to go through this hehe.
Hello everyone, I'm at 8:23 of the video when he's showing us how to display the players health on the console but for whatever reason it is not displaying it.

@@Dani_Krossing Hey Dani, thank you for responding but yes. Everything worked fine up to this point. I was following your code and went to unity when you did to see the changes and everything was working fine up to this point. I don't know what other information I can provide. I want to really understand your tutorials before moving on the rest of your videos.
Best advice I can give you, is that the error is with Unity, and not the code, since I can’t find any errors on my 2nd look through. So check anything Unity related, that could have gone wrong. 🙂 Things like making sure you saved your document, that the script is attached to a game object, and that it is the correct script in case you accidentally created multiple at one point while following the video… etc…
@@Dani_Krossing So I continued with the tutorials and I'm on the 5th video. Something must be wrong with unity some kind of setting because nothing is showing up on the console. I'm at the 9:00 minute mark where it shows the players health as 90. I wish I could post a screenshot of unity but the document is saved, the script is attached to the game object and I only have one script as you do in the video. lol idk what's going on.

Hi, is array work with get/set method?
like this one public int[] Playerhealth { get; set; }
Something that others may have asked, and I''m surprised you didn't add, is what DOES the clamping look like? Is it as simple as PlayerHealth
god bless you elon musk i just wanted to let you know that your c# videos help me substantially and you are signifcantly better then the professor teaching the course i am currently in
LMAO
🤣🤣🤣
This is the BEST explanation of 'Properties' I have ever come across.
These are actually great videos that help me understand what I’m doing instead of just doing it

you teach a lot better than those paid teachers on udemy, you saved my day !
You’re here from the rpg course aren’t you?
You can type out "prop" and hit tab to use intellisense to create an auto property quickly. Default behavior creates a public integer property.
Dude, thanks to you, now I feel like I can make any website, I’m goin go to new languages already, thank you very much sr
I think I've found the perfect tutorial. Thank you very much and do not stop doing it, please.
Thank u so much for everything, I am just starting up and follow all ur step, and it was really beginner friendly! Absolutely splendid!
Just started watching this series, very good you tech me ehat to do instead of just me copying code.
Thanks a lot sir, we need more ppl like you. i like ur way to explain every step :DDDDD
The C# syntax for get and set methods (properties) is something I will have to get used to. I'm used to the way that Java creates get and set methods.
Earned a new subscriber, master. Looking farward to gain more knowledge

@@Dani_Krossing noted, thanks! Will make sure to visit some of your other tutorials aswell.
By the way, it is possible to expose properties to the Unity inspector by adding the tag [field: SerializeField] above the property.
The quick code change at 9:19 made me think I was going crazy for a second.
Hi Dani, I am trying to learn Unity. I have coded in AGK and I would use what is known as a type.

Quick question: why was the variable in the Field called _playerhealth = 100 set to private, but the property Playerhealth set to public?
Thanks bro for this series. 😀🙌🏻
Loving this series but i have a question about auto property ? The field that will be created in that so what would be the scope of that field public or private ?
That’s a really good question. 🙂 I’m assuming the field is private, seeing that if it is public, then it defeats the purpose of using properties.
@@Dani_Krossing Thanks alot you're a absolute banger
love the inheritance joke
Really helpful video, thank you!
You did a great tutorial series man !
but what makes me using get set, if changing PlayerHealth from another script it will change _playerHealth too

and why do i need to make a get while i just can do a function with return value to make it read only ?
and why do i need to make a set while i can make a function to set that value, and do all kinds of operations i want before setting it ?
i finally understand it
Top quality!

Guess what I just realized : You look just like Elon Musk man! :)
Elon musk little brother is teaching code, what else you want??
Btw, nice explanation!
he should go and make a withdrawal from a certain bank acct 🤣
i'm confuse, you said that if I have a property PlayerHealth{get; set} , it will auto create a field of _playerHealth, but i tried and can't access the field inside the class. Why?
Because the field is private 🙂 you have to use the property to access it.
great video
does "playerhealth = value;" mean the value of the playerhealth?
so the value would be 100?
Yes because we assigned the player health inside our Field, in this example here it would be 100. 🙂 Later on when we get into creating objects and using constructors, we won't assign a value directly inside our class, but instead will assign it as we create objects.
Good video, but was too distracted by your low cut shirt.
