My issue with default interface method is that it starts to blur the line between abstract classes and the classical definition of an interface (i.e. interface is a contract). I've honestly ran into interesting design pattern problems where I really wanted to have a default interface method, but then I thought it was a bad design from my part that trapped me in that corner. Even though I know that this is more of C# discussion rather than Unity discussion, but I'm curious to hear/read your opinion about it :)

I imagine that the only difference now is that there is no multiple inheritance in C# so you can only inherit 1 abstract class. But your class can have more than one interface implementations.

@LeMustache, I already see what you are saying, but what about the possibility of diamond shaped interface implementation in this case (is that even possible now?) I didn't try it yet to see how the compiler handles it. And interfaces are no longer "contracts" unless you inforce it when you are developing with a team. So yeah, very interesting language design decision. Probably not introducing that feature and tell developers to write extension methods is a better idea? I don't know what would be the right answer in this case tbh.

If you do "-1" you're still passing an integer to the indexer, which is handled by implementing something like public T this[int index] We could always do this. Meanwhile, ^1 is special syntax for "new Index(value: 1, fromEnd: true)" and would be handled by implementing an indexer like public T this[Index index] Also, protip, use Index.End or Index.First instead of ^1

Good point. And refactoring how arrays and indexing works to include out of range indices could not only break things (and not be backwards compatible), but may also slow down arrays a little bit as they'd have to do an extra step to parse the index. Guess they've thought of this 😅

It's kinda weird why wouldn't they utilize unity tiny project to build something like Open fuse ( app development framework uses opengl) I believe unity could cut down app size , using .net core runtime or by new platform with burst compiler just like open fuse but with c# and all the tools we like in Unity editor.

Correct me if I am wrong, because it appears you have lost the plot. Unity introduce C#8 into Unity 2020.2, or at least the vast majority of that support. And as of Unity 2021.2, they introduce a small subset of C# 9.0, so I am confused how they then snuck this up to C#10 when not even all of C#9 is supported as yet? And C#11 is not even finalised and no work has even begun on that as yet. Did you have too much to drink New Years Eve? And 2 of the 3 things you mentioned I have specifically been using since Unity 2020.2, the other I am not 100% certain it was in that version of Unity.

readonly on a property or method looks a lot like class member function “const” in C++, but there a “mutable” keyword on a data member is needed in order to implement optimisations like memoisation and logging. In this video, to be analogous, the LastDistanceUpdated time stamp should somehow be allowed to be modified even though Distance is readonly - does C# 8 provide for this?

@MidnightSt

2 жыл бұрын

readonly on a (public) property means it's read-only *from the outside*. it's a shortcut for Property { public get; private set; } You can still change its value from the inside of the class that owns the property.

@meowsqueak

@@MidnightSt in the video the readonly keyword is applied to a method / member function, and the “fix” shown to get it compile is to remove a change to a non-readonly property. What I’m asking is how to mark that property as mutable so that a readonly method can modify it internally. Edit: I suspect what I’m asking isn’t possible due to the way C# handles value types - a mutable internal field of a struct modified by a “readonly” method would break the compiler’s ability to avoid a copy, so probably doesn’t make sense like it does in C++.

Nice Video, Thank you! Can anyone tell me why C# allows Methods in Structs? I learned that structs are only for data. I dont even think other languages allow this.

@GiraPrimal

2 жыл бұрын

That "only struct for data" convention kinda makes sense in languages like C++ where there’s almost no difference between classes and structures. In C++, only the default member accessor changes. Things work a bit differently in C#. Structs are value types, meaning they are copied when passed to a function or to a variable, and instantly destroyed when you no longer need them. They do not support inheritance, but they do support interface implementation. Classes are reference types, which means you’re only passing a reference to the same instance of a class when calling a function or changing a variable. The instance is only destroyed later by the garbage collector when all references to it are lost. They support class inheritance and interface implementation. There are other subtle differences, but that’s the basics. In C#, it’s good practice to use structs only to hold small amounts of data, or in some cases when you want to keep full control of memory usage. With both types, it’s a good idea to define methods to manipulate them easily.

I worked with C++ for years, and recently moved to C#, honestly this is night & day, it's a lot of time saving, C# is way easier and more modern to program with, the only issues is on the security aspect, it's way easier to obfuscate and protect your code from piracy/reverse engineering when working with C++, because it's a closer language to assembly. C# on the contrary it's really easy to decompile and stole your code. EDIT: Forget about visual scripting, you will never become a real dev if you do visual scripting, maybe it's worth as a begineer to start with, but as soon as you're familliar with some programming concepts move to real programming, it's way better and possibilities are endless !

Oh. So Interfaces have now become almost classes, in the name of having one of their main points removed =D. "Nice". Changing an interface is difficult, because it breaks all implementors. YES, that's the point. It's a contract. Changing a contract SHOULD be difficult and anger everyone who is currently bound by it. That's the point of a contract. If you need to change the contract when it's already in use... You have failed at making the contract, and no amount of turning Interfaces into Classes will save you. The only thing that putting functionality into interfaces will do, is shoot you in the foot even further.
