Thread: Linker errors with static abstract class...

I never understood that error message until now.

Thanks Elysia!

You're welcome
Btw, it doesn't have to be a function. It can also be a variable, as you just witnessed. But it's the same in that it wasn't able to find it!

Also, if you're all curious, I'm working on getting rid of this mess:

Code:

void Card_Game::play_game()
{
	using namespace std;
	int gameloop = 1;
	int result = 0;
	int controller = 0;
	
	while (gameloop != 0)
	{
		IO::instance().clear_screen();
		switch(controller)
		{
		case 0: // main menu
			std::cout << "Welcome to the Casino!\n";
			std::cout << "What would you like to do?\n";
			std::cout << "1. Play Blackjack\n";
			std::cout << "2. Quit\n";
			result = IO::instance().get_input();
			controller = main_menu(result);
			if (controller == 4)
			{
				gameloop = 0; // end game
			}
			break;
		case 1:	// blackjack function
			cout << players[0].show_hand();
			std::cout << players[1].show_hand();
			std::cout << "The current jackpot is " << pot->get_pot() << " dollars!\n";
			std::cout << "\nWhat would you like to do?\n";
			std::cout << "1. Hit me\n";
			std::cout << "2. Stay\n";
			std::cout << "3. Fold\n";
			result = IO::instance().get_input();
			controller = blackjack(result);
			break;
		case 2: // deal again?
			for (unsigned int loop = 0; loop < players[0].hand->card_list.size(); loop++)
			{
				players[0].hand->card_list[loop].flip_card(true);
			}
			std::cout << players[0].show_hand();
			std::cout << players[1].show_hand();
			if (player_wins == true)
			{
				std::cout << "You win!!\n"
						  << "You've won " 
					      << calculate_winnings()
						  << " dollars!\n\n";
				players[1].cash += calculate_winnings();
			}
			else
			{
				std::cout << "You Lose!!\n"
					      << "You've lost "
						  << pot->get_pot()
						  << " dollars!\n\n";
			}
			std::cout << "Would you like to deal again?\n";
			std::cout << "1. Yes\n";
			std::cout << "2. No\n";
			result = IO::instance().get_input();
			controller = deal_again(result);
			break;
		case 3: // place bets
			std::cout << players[0].show_hand();
			std::cout << players[1].show_hand();
			std::cout << "How much would you like to bet?  You have "
				      << players[1].cash
					  << " dollars.\n";
			controller = place_bets(IO::instance().get_input());
			if (controller == 4)
			{
				controller = 3;
			}
			break;
		}
	}
}

I've decided to do some research on gamestates and I figure that I could easily simplify my code to something like this:

Code:

int main ( int argc, char *argv[] )
{
  State_Manager state_manager;

  // initialize the engine
  state_manager.init();

  // load the intro
  state_manager.change_state( Menu_State::instance() );

  // main loop
  while ( state_Manager.running() )
  {
    state_manager.update();
    state_manager.draw();
    state_manager.handle_events();

  }

  // cleanup the engine
  state_manager.cleanup();
  return 0;
}

Wonders of classes, no?

YES, it's quite amazing, thats why I'm trying to make this work though, because the result is something close to perfection bwahhaha
