A100:

It depends on where - you need a complete example to answer the question

Anywhere that fits into the context. I find the entry itself somewhat absurd, despite its validity.

Before // the entry is normal... afterwards it's absurd.

I don't see anything absurd in wanting to assign a function field to a pointer to a method

typedef void (*fn)();

void g() { Print(__FUNCSIG__); }

struct A
{
  fn f;
  
  A() : f(g) {}
};

struct B : A
{
  void f() { Print(__FUNCSIG__); }
  
  void A100()   { this.f = this.f; } // не присвоить полю-функции указатель на одноименный метод, а на другой метод - пожалуйста:
  void A100_2() { this.f = this.h; } // 'h' - pointer to this function type is not supported yet
  
  void h() { Print(__FUNCSIG__); }
};

void OnStart()
{
  B b;
  
  b.f(); // void g()
  
  b.A100();
  
  b.f(); // void g()
}

What is absurd is that the compiler does not support pointers to simple methods, and even if it did, a pointer to a simple method and a pointer to a simple function will have a different signature, all other things being equal

 
A100:

a function pointer and a simple method pointer have a different signature

how is a static method different from a function in terms of signature?

 
fxsaber:

static methods are no different than functions when the signature matches

 
A100:

Static methods are no different in signature from conventional functions

How is that a bad thing, then?

typedef void (*fn)();

void g() { Print(__FUNCSIG__); }

struct A
{
  static fn f;
};
static fn A::f = g;

struct B : A
{
  static void f() { Print(__FUNCSIG__); }
  
  void A100() { this.f = this.f; } // по смыслу ничем не отличается от A::f = B::f
};

void OnStart()
{
  B b;
  
  b.f(); // void g()
  
  b.A100();
  
  b.f(); // void g()
}
My point is that such hobbies lead to ambiguities. Which are useful except as one of the tests of language comprehension in job interviews.
 
fxsaber:

What's wrong with that, then?

The bad thing is that in C++ the result will be different

So it's not justified either.

What is it?


After selecting "Save Version", the current parameters are saved to the built-in MT list, which can be used from the "Load Version" menu. The list is different for each EA.
