Checking coordinates
The InputCoordinate method is within the Simulation class, see below:
1 private int InputCoordinate(char Coordinatename)
2 {
3 int Coordinate;
4 Console.Write(" Input " + Coordinatename + " coordinate: ");
5 Coordinate = Convert.ToInt32(Console.ReadLine());
6 return Coordinate;
7 }
This is called everytime a coordinate is required. It can easily be validated because at the LandscapeSize variable could be used. So:
1 private int InputCoordinate(char Coordinatename)
2 {
3 do
4 {
5 Console.Write(" Input " + Coordinatename + " coordinate: ");
6 Coordinate = Convert.ToInt32(Console.ReadLine());
7 }
8 while (Coordinate < 0 || Coordinate >= LandscapeSize);
9 return Coordinate;
10 }
The Coordinate is invalid if it is less than zero or greater than or equal to the LandscapeSize (ie first element is 0).
