Are there any disadvantages to this approach? (re-calling a method from a method on a condition)

Unity Engine

I have a simple if statement:

public void AMethod()
{
     //AMethod works and does its thing
     if (something == some value)
     {
            AMethod();
     }
}

something is equal to some value very rarely and after running AMethod() stops being equal to some value.
AMethod() is also called rarely.

My questions are:

  • what are the disadvantages of doing so?
  • what are the alternatives if a method needs to be re-called from within the same method?

Thank you for your answers!

Having a method call itself is fine, as long as you’re careful to ensure it can’t get caught in an infinite loop. Remember that anything in your function that’s after the self-call won’t happen until the self-call is completely finished (but will still happen, if you don’t do anything to stop it).

This is called recursion, as Anti points out above.

To understand recursion, you must first understand recursion.
