[@strongforce8466]

@@1ninozinho That's what I was wondering, can it be finished already ?? I only watched a few but I been meaning to get into it, due to the complexity it feels like c# could need many more videos to cover but then again I don't know that much about it, if he didn't finish it though then it would feel almost heartbreaking !! he can't leave us like that ? "crying smiley"

[@lachy4565]

@StrongForce I get what you mean but I'm pretty sure this is just meant to be a beginners course. It teaches you the basics of c#, and from there you can pretty much learn whatever you want. You only need these few skills to actually start coding real programs that you can you and if you need or want to learn anything else you can just search up the documentation.

[@MiScusi69]

This is the best series I've ever followed. Now I've got a new skill!

[@KyuVulpes]

I know this is pretty petty, but, a bit of the styling you said is wrong. Underscores are to denote either a field (a class/object variable) is to not be touched outside the property, or that it is only meant to be seen either internally or private. You should never use underscores for field names because that will be confusing. I mean, look at the main method header or anytime you create an object using a parametered constructor. None of them use that underscore for any of the parameters. Also, Pascal Casing for a "field" would tell me it is not a static field, but a property. Which, too, is seen throughout libraries and other C# programs. Onto another issue I have with this. You have made fields public, this is a major no-no for classes. The only time a public field is acceptable is when it is a struct, not a class. The reason is that structs are a ValueType, this means that they reside on the stack when used inside a method, and in the heap when used outside the method. And whenever you pass a ValueType, you are making a copy of it. With a class, it is pass by reference. Classes only live in the heap and cannot live in the stack. Which means that no matter what, access to them is going to be slow since you have to go outside the stack (which is a linear region of memory) into the heap (which is not arranged in any way). If anyone who sees this wants to know how to choose between a struct (ValueType) and a class (ReferenceType), check out this StackOverflow answer (stackoverflow.com/a/1951243/9116918).

[@phoxsty]

I agree with the first paragraph you wrote, especially the part where he says "it is standard practice to always capitalize the first letter in a static variable". But in the second paragraph, there are some more subjective parts. Using public variables in a class is not all bad. While yes it might be slower it is still easier and you have to remember this is a beginner's course. There is optimization that can be done for sure but teaching that to someone who does not even know what a class is would just overwhelm them with information and it's better to let them use this "worse" way for now and then teaching them another way later.

[@menyus777]

Then how would you add a value type to a class, if not via a field?

[@phoxsty]

@@menyus777 That's the whole point. You don't. ValueType would have to be a Struct instead.

[@menyus777]

@@phoxsty Sounds kinda stupid a class should not contain value types? O.o

[@marc-antoinegirard2178]

​@@menyus777 It's because it is stupid. There are 3 basic rules to use a struct. 1: It should represent a single value (Unity, for instance, uses struct for Vector3, because it represents ONE coordinate, and for many other optimization reason). 2: It should be immutable. 3: It should not be boxed and unboxed frequently. Unless you are excessively certain that a struct is the best option for your application, and I mean it (like that you know what is a readonly struct, you understand clearly the "in" parameter modifier, that you understand boxing and unboxing, that the specific needs you have require a struct like in DTO pattern, that you understand the importance of passing a struct by ref, that you care immensely about optimization (like in ECS, which would mean you understand what is a cache miss and what the cache line is), you should not even use a struct. If you are a beginner, you should know what a struct is, how to use it, but not declare one because "it's optimal". A slight messup in its usage and it becomes slower than a class. So to conclude, value types in a class is as normal as clouds in the sky. If you pass a class as a parameter, you're only passing its reference (an int sized pointer), nothing else is passed, so chill.
