Listing 19-14 shows the code for the Evaluate method.
Listing 19-14. AttackEnemyOption::Evaluate
void AttackEnemyOption::Evaluate(Player& player)
{
std::cout << std::endl << "You have chosen to " << m_outputText
<< std::endl << std::endl;
if (player.HasWeapon())
{
if (m_enemy->IsAlive())
{
m_enemy->Kill();
std::cout << "You killed it!" << std::endl << std::endl;
}
}
else
{
std::cout << "You need to find a weapon before attacking monsters!"
<< std::endl << std::endl;
}
}
The Player::HasWeapon method is put to good use here to make sure that the user can only attack
enemies when they are armed. The final changes required to tie everything together are in the Game
class, which is shown in Listing 19-15.
