我正在制作一个控制台应用程序游戏 (C#)，但我遇到了堆栈溢出错误。 如何避免？

Question

My game has multiple methods for each state of the game and these methods call each other where applicable. This is causing a Stack Overflow Error after a while. Is there any way to avoid this, perhaps a workaround?

Edit: As the user below suggested my code is basically:

void a()
{
    b();
}

void b()
{
    a();
}

In this code I intended to use recursion in order to change game states. Is there any way to reset the stack so it doesn't cause an overflow error and then return to the methods.

Possible Fix: (Did this just delay the Stack Overflow or has it gotten rid of it?)

int tracker;
void start()
{
    a();
    resetter();
}

void a()
{
    b();
}

void b()
{
    if (tracker > 10)
    {
        tracker = 0;
        return;
    }
    else
        tracker++;
    a();
}

void resetter()
{
    start();
}

I assume you're doing something like:

void A()
{
  B();
}
void B()
{
  A();
}

This, by definition, will always cause a stack overflow. This is basicly because of how the stack works. Say you call A first, the moment this method calls B , the parameters/variables/... for this method are put on the stack. Then, this method ( B ), calls ´A´; the moment that happens, it will put its parameters on the stack.

The data on the stack is cleared after a method returns. But these two methods will never ever return... They keep on calling one another, something like:

A()
  --> B()
    --> A()
      --> B()
        --> A()
          --> B()
            --> A()
              --> B()
               --> A()

As you can see, more and more stuff is put on the stack, causing your overflow.

You will want your recursion to stop to fix this. You can do this by introducing a stopping condition in either method which will return .

If you wish a more concrete answer to your question, please add some code. But since you're talking about A calling B, which is calling A, the above pseudocode should be adequate.
