The
RunGame
function returns a
bool
, the
shouldEnd
variable. This function is designed to be called
from a loop and simply calls the other functions that represent the different stages of our game at
the moment. The return value from
EvaluateInput
is checked to determine if the player has decided
to quit the game.
bool RunGame()
{
bool shouldEnd = false;
GivePlayerOptions();
string playerInput;
GetPlayerInput(playerInput);
shouldEnd = EvaluateInput(playerInput) == PlayerOptions::Quit;
return !shouldEnd;
}
Our program's entry point is still the
main
function. This function calls
WelcomePlayer
then executes a
while
loop that will iterate until the player has selected the quit option.
int main(int argc, const char * argv[])
{
Player player;
WelcomePlayer(player);
bool isPlaying = true;
while (isPlaying)
{
isPlaying = RunGame();
}
return 0;
}
We have now written a program that is beginning to resemble a game. We have put the core game
loop into place and from here we will be able to add new functionality to our existing functions.
