Dynamic Delegate (C++)

Define a dynamic delegate like in the Unreal framework, but without using the Unreal framework! The delegate can be subscribed by a pair of a YourBaseClass* and a function to call on the base class. Broadcast() will call the functions on the respective objects. You will find the useage below and the source code in the repository.

DECLARE_DELEGATE(DestroyDelegate)

int main()
{
	DestroyDelegate Destroy;
    
	GameObject* gameObject2 = new GameObject("GO 1");
	GameObject* gameObject3 = new GameObject("GO 2");
	GameObject* gameObject4 = new GameObject("GO 3");
    
    printf_s("Adding function GameObject::Destroy of GO 1, 2 & 3 to delegate Destroy...\n");
	Destroy.Add<GameObject>(gameObject2, &GameObject::Destroy);
	Destroy.Add<GameObject>(gameObject3, &GameObject::Destroy);
	Destroy.Add<GameObject>(gameObject4, &GameObject::Destroy);
    
    // ...
    
    printf_s("Broadcasting delegate Destroy...\n");
	Destroy.Broadcast();
    
    return 0;

Output

Adding function GameObject::Destroy of GO 1, 2 & 3 to delegate Destroy…
Broadcasting delegate Destroy…
GO 1 was destroyed
GO 2 was destroyed
GO 3 was destroyed
