Unity – c# get, set 키워드

c++ 에서 private 멤버 변수에 접근하기 위해

아래 소스 처럼 접근자를 만들어 사용했다.

class CppStyle { private : int data; public : int GetData() { return data; } void SetData( int data ) { this ->data = data; } };

c# 에서는 get 과 set 키워드를 이용해 이를 해결한다.

class CsStyle { private int _data; public int data { get { return _data; } // _data 반환 set { _data = value ; } // value 키워드 사용 } }

data 뒤에 괄호가 없으므로 메소드가 아니며 코드 사용시에

CsStyle csst = new CsStyle(); csst.data = 10 ; // set int a = csst.data; // get

변수 쓰듯 사용하면 된다.

3.0 버전부터 가능한 방법으로 다음과 같은 방법도 있다.

class CsStyle { public int data { get ; private set ; } }

data 을 읽을 수는 있지만 변경은 불가능 하다.

반대로 읽을 수 없고 변경은 가능하게도 할 수 있지만 전자를 많이 쓰게 될 듯 함.

C# “Get and Set” functions and the Unity Inspector

Code (csharp): [ SerializeField ] private float privateBackingField = 0 ; public float PublicAccessibleProperty { get { return privateBackingField ; } set { privateBackingField = Mathf . Clamp01 ( value ) ; } } void OnValidate ( ) { PublicAccessibleProperty = privateBackingField ; }

I’ve not used it myself, but the OnValidate method in a MonoBehaviour could be useful for using setter methods via a default Inspector.My untested assumption is that we could mark the backing fields with [SerializeField], make public setter methods which enforce whatever rules we want to have, and have an OnValidate method similar to the following:I believe this would mean that every backing field is re-applied via its public property each time an Inspector value is changed. As long as you don’t have any complex interdependencies between your properties this should be a pretty straightforward solution, in theory. (And even with complex interdependencies it shouldn’t be that much more difficult, since you can just call whatever you’re using to enforce them anyway.)Heck, I bet you could even use reflection magic to automate this from a common subclass of MonoBehaviour.Tested the above code. Works great.I will totally be using and abusing this from now on.Of course the downside to this is that the getter isn’t actually being used by the Inspector, so if we’ve got any kind of data transformation going on there it’ll be getting ignored. So contrary to what I initially had written above, this is handy for applying rules on set but not so useful on get. For that I believe you would indeed need a custom Inspector, because you’re looking to change the basic rules by which Unity displays stuff in there. (Or… hacky approach… have separate private backing fields for the Inspector and for runtime, and update the Inspector fields via their getters at the end of OnValidate… but that’s really getting funky and I wouldn’t want to maintain it on a large codebase, and it still wouldn’t be particularly reliable for derived getters… I think a custom Inspector would be a clearer approach.)

What does “{ get; set;}” in Unity mean?

\$\begingroup\$

I have seen people doing things like ‘public int xyz { Get(); }’ but i dont understand how that would work.

These are called properties. They’re a language construct that allows you to expose data from a type that looks like a field when you access it, but acts like a pair of functions in that you can have behavior execute whenever the property is read (the “getter”) or assigned to (the “setter”).

Consider this:

class Thing { private int secret; // This is a field. public int Secret { // This is a property. get { Debug.Print(“Somebody is accessing the secret!”); return secret; } set { Debug.Print(“Somebody is writing to the secret!”); secret = value; // Note the use of the implicit variable “value” here. } } }

The Secret property has both a getter and a setter; these are really just functions that can execute any code you want. You can then do:

Thing thing = new Thing(); thing.Secret = 23; // Use the setter. Debug.Print(“Set the secret to {0}.”, thing.Secret); // Use the getter.

Note that it looks like you’re accessing a field here (no () is used to get or set Secret ), but you’re still actually calling the get and set functions you wrote above.

C# supports quite a bit of shorthand around properties. For example, declaring a property like you’ve seen:

public int Secret { get; set; }

Tells the compiler to generate a backing field for Secret for you, and set the getter/setter to some code that just returns or writes to that backing field.

Quite a bit more detail can be found at the MSDN link I shared at the start of this post.

Is the way I’m doing ok (it does seem long-winded to me) or should I investigate these Getter Setters some more?

What you are doing is fine, if you are happy with it. It will be worth your while to learn about C# properties, however. If nothing else, you will encounter them often in code other people have written even if you prefer not to use them yourself, so it will be good to understand them. It is also useful to know how to use properties because they are treated differently from regular fields in reflection, and many tools (Unity included) use reflection to find and identify data associated with your types. Some of those techniques will not work with simple fields because they assume the use of properties, and so you may need to use properties if you want to take advantage.
