delegate inside our outside class?

delegate void ADelegate(); // here?
public class PlayerShip : MonoBehaviour
{
    delegate void ADelegate(); // or here?
    event ADelegate DelegateHandler;
}

delegate void ADelegate(); // here?
public class PlayerShip : MonoBehaviour
{
    delegate void ADelegate(); // or here?
    event ADelegate DelegateHandler;
}

Should I create a delegate inside or outside a class? Is there a difference?

Being inside a class, you can give it more access modifiers But unless accessing it from the declaring class, you'll need the full name PlayerShip.ADelegate

you can put delegates outside of classes?

TheBoxyBear•3y ago

Like how you can have classes inside classes

i haven't been using them at all lol i've never seen a use for them

They are useful. It's like a redirect or a shortcut to piece of code, a pointer to particular methods Yeah, I know when it's inside a class and when I want to use it from other class I use class name dot variable name e.g. System.Random or UnityEngine.Random I was asking though if there is a difference if I put a delegate outside class, like in the 1st line

It's the same as declaring a class inside another class, vs directly in a namespace The general advice is not to have public nested types, and that includes delegates and enums So avoid public nested delegates

Do you mean public delegates inside a class? So I should put them in a namespace like in the 1st line?

canton7•3y ago

Yes Nested means defined inside another type

// PlayerShip.cs
delegate void ADelegate();
public class PlayerShip : MonoBehaviour
{
    internal delegate void BDelegate();
}


// OtherShip.cs
public class OtherShip : MonoBehaviour
{
    ADelegate habazi = () => Debug.Log("");
    PlayerShip.BDelegate wdwds = () => Debug.Log("");   
}

// PlayerShip.cs
delegate void ADelegate();
public class PlayerShip : MonoBehaviour
{
    internal delegate void BDelegate();
}


// OtherShip.cs
public class OtherShip : MonoBehaviour
{
    ADelegate habazi = () => Debug.Log("");
    PlayerShip.BDelegate wdwds = () => Debug.Log("");   
}

Okay, so I guess this is the only difference? Different way of accessing them?

Yeah, pretty much. The other is that nested types can be private/protected, which can be handy. That's the one time I would nest one
