Talk:WORLD.DAT

  // World.Dat = World Map Terrain
  
  typedef struct worlddat
  {
     short         QuadData[4][2]; // Coordinates of quadrilateral
     unsigned long texture;        // Terrain texture of quad
  } WorldDat;
  
  #define MaxQuads 768      // Observed values, XCOM = 666, TFTD = 733

QuadData/8 = realworld latitude and longitude numbers.

if QuadData[3][1] = -1 then the shape is a triangle and that entery is not used. (for you non programers QuadData[0] is the first so [3] is the forth.)

This may not be usefull for the wiki but I once wrote a program to detect what world.dat entry a givin ship was located in and therefor what texture/terrain file used to create the battlescape map. I have the function if anyone is interested in the math.
