Ok so im makeing a time management game and you buy trucks and planes and send them off to different parts of the world and it takes real time so i made a timer to keep tract of stuff and every vehicle will have its own timer but i want to know how do i create multiple timers without copying and pasting in the code?

Use a class that is in charge of managing all your timers. Also I would recommend you look into the time header for a better timer, and look into using classes.

but the player will be allowed to have an unlimited number of vehicles so how would that work? I dont know how to set that up in a class anyways.

Oh and im facing another problem, my timer is not running unless im in the function, can i make it run while im in other functions without making it global?

Yes that is why I am telling you to make a timer class, and a timer manager class and to look into the time header (time.h).

That way you can have multiple timers running in the background.


Here is some links that might help

Ok im going to be honest here, i looked at that documentation and am not any further along with my project, I need to see examples, maybe someone could start me off with a shell of a timer class and see if i can fill in the rest, i have a learning disability so it takes me a while to grasp something.

Take a look at the example for
http://www.cplusplus.com/reference/ctime/clock/

clock_t t;
makes a timer object.

t = clock();
sets it to the current time.

elapsedtime = clock() - t;
gives you the time that has passed

Play with the example on that page to get to grips with it.

You don't need multiple timers, but you do need classes:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
class Clock {
private:
  unsigned int time_in_seconds;

public:
  Clock(void) : time_in_seconds(0) {}
  Clock(unsigned int seconds) : time_in_seconds(seconds) {}

  void increase(void) {
    time_in_seconds++;
  }
  unsigned int time(void) {
    return time_in_seconds;
  }
};


Your shipments should be classes too:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
 
class Shipment {
private:
  unsigned int shipping_date;
  unsigned int distance_in_seconds;
  bool         arrived;
  unsigned int recieved_date;
public:
  Shipment(unsigned int date, unsigned int dist_seconds)
    :shipping_date(date), distance_in_seconds(dist_seconds)
  ,arrived(false), recieved_date(0)
  {}
  bool hasArrived(unsigned int time_in_seconds) {
    if (arrived) return true;

    if (time_in_seconds < shipping_date + distance_in_seconds)
      return false;

    recieved_date = time_in_seconds;
    arrived = true;
    return true;
  }
  unsigned int time_recieved(void){
    return recieved_date;
  }
};


To use these classes:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
 
int main(void)
{
  // Create the clock
  Clock myClock;

  // Make some shipments
  Shipment myFirstShipment(myClock.time(), 5);
  Shipment mySecondShipment(myClock.time(), 7);

  // Pass the time
  while (!myFirstShipment.hasArrived(myClock.time())
      || !mySecondShipment.hasArrived(myClock.time()))
  {
    myClock.increase();
  }

  // Results
  std::cout << "F Shipment @ " << myFirstShipment.time_recieved() << '\n';
  std::cout << "S Shipment @ " << mySecondShipment.time_recieved() << '\n';

  return 0;
}

Ok now in my game there will be tons of different vehicles all with their own timers and stuff, this code will be able to handle that?

That means you don't understand what it does. I would recommend you figure out exactly what his classes do before you use them :)

Vehicles don't have timers. They have times they expect to arrive, and given a time, know if they have arrived or not.

Ok well I guess i need to understand the clock function and time stuff before i continue, is there any videos or really good tutorials about that stuff anywhere besides the ones on this site?
