RequireDerivedAttribute

설명

When the type is marked, all types derived from that type will also be marked.

using System;
using UnityEngine;
using UnityEngine.Scripting;

public class NewBehaviourScript : MonoBehaviour
{
    void Start()
    {
        new Foo();
    }
}

[RequireDerived]
class Foo {}

// UnusedFoo is not used, however, it will survive managed code stripping due to Foo having the [RequireDerived] attribute.
class UnusedFoo : Foo
{
    // Note that unused members of UnusedFoo will still be removed by managed code stripping
    public static void UnusedMethod() {}
}


// Bar is not used so it will be removed by managed code stripping
[RequireDerived]
class Bar {}

// Because Bar is not used, the [RequireDerived] attribute on Bar has no impact.  UnusedBar will also be removed.
class UnusedBar : Bar {}
