direction source code

[Fojam]

I am working on a project in another programming language for a class, and it would be really helpful if someone could share the source code for the direction function? Does anybody know what it is?

It is defined in ./gameEngine/Script.cpp.

Code: Select all

double direction(double x1, double y1, double x2, double y2)
{
   /*
   Direction between (x1, y1) and (x2, y2)
   (0 to 360, from x axis, counterclockwise, in degrees)
   */
   
   double angle = 0.0;
   
   if(x1 != x2 || y1 != y2)
   {
      if(y1 == y2)
      {
         if(x2 < x1) angle = 180.0;
         else angle = 0.0;
      }
      else if(x1 == x2)
      {
         if(y2 > y1) angle = 270.0;
         else angle = 90.0;
      }
      else
      {         
         angle = atan2(y1 - y2, x2 - x1)*180.0/Script::PI;
         if(angle < 0.0)
         {
            angle = 360.0 + angle;   
         }
      }
   }

   return angle;
}


There are other ways to do it. This seems a bit lengthy considering you just want the direction between point a and point b.
