Most (if not all) games will remember the things (money, village size, manager amount, etc.) that you have so that when you start the game again, you still have everything you had obtained when you last left off. I am programming a game that needs to remember values, and I declare them initially at the beginning of the program. But since money equals zero, every time the user comes back to play the game, their earnings will be reset.
I will ultimately need this for most of my variables but I am actively working on Tutorial();. I am going to need the tutorial to only run once so I need the program to check whether the user has completed the tutorial every time the program begins. I have tried setting up a boolean value called isTutorialCompleted and having it check that in main when I run my functions. Code:
#include <iostream>
#include <string>
#include <vector>
using namespace std;
//Game Variables
int money = 0;
string existingManagers = { "Benny, Rachel, Barnes, Flora, Gregory" };
string createManager = "";
vector<string> createdManagers {""};
bool isTutorialCompleted = false;
void initApp () {
}
void Tutorial() {
cout << "Please Enter your name" << "\n";
cin >> createManager;
createdManagers.push_back(createManager);
cout << "\n" << "You have created Manager " << createManager;
}
int main() {
initApp();
if (isTutorialCompleted == false) {
Tutorial();
}
}
This did not work due to the fact that every time I restarted the program the boolean value would reset so I tried making the boolean value undefined initially and then having it change in Tutorial. Code:
#include <iostream>
#include <string>
#include <vector>
using namespace std;
//Game Variables
int money = 0;
string existingManagers = { "Benny, Rachel, Barnes, Flora, Gregory" };
string createManager = "";
vector<string> createdManagers {""};
bool isTutorialCompleted;
void initApp () {
}
void Tutorial() {
isTutorialCompleted = false;
cout << "Please Enter your name" << "\n";
cin >> createManager;
createdManagers.push_back(createManager);
cout << "\n" << "You have created Manager " << createManager;
isTutorialCompleted = true;
}
int main() {
initApp();
Tutorial();
}
The problem with this is that it would not keep the value. isTutorialCompleted would go back to undefined in the program and ultimately change to false when tutorial begins. Finally, I tried checking for the boolean value in initApp();. Code:
#include <iostream>
#include <string>
#include <vector>
using namespace std;
//Game Variables
int money = 0;
string existingManagers = { "Benny, Rachel, Barnes, Flora, Gregory" };
string createManager = "";
vector<string> createdManagers {""};
bool isTutorialCompleted;
void initApp () {
//Check if tutorial is completed
if (isTutorialCompleted = true) {
Tutorial();
}
}
void Tutorial() {
cout << "Please Enter your name" << "\n";
cin >> createManager;
createdManagers.push_back(createManager);
cout << "\n" << "You have created Manager " << createManager;
isTutorialCompleted = true;
}
int main() {
initApp();
}
So the ultimate question is: How do you permanently store a variable so that when you restart the program, the stored variable does not reset?
