GetFieldId

This function converts coordinates into a field id.

The field id is a number between 0-63999. Each number directly corresponds to a square on the 800x800 grid map. The game server uses field ids to reference all the squares on the map... 0,0 has field id of 0.... 1,0 has field id of 1... 799,0 has field id of 799... 1,1 is field id 800... and so on. Many of the advanced scripting functions require you to convert your coordinates into fieldIds to use them.

This example finds the coordinates of a field id:

• coords = "460,355"
  echo GetFieldId(coords)
  
  Result:
  15:07:40 Starting script
  15:07:40 Running line 1
  15:07:40 coords = 460,355
  15:07:42 Running line 2
  15:07:42 284460
  15:07:43 Script stopped

FieldIdToCoords

This function converts a field id into coordinates.

This example finds the coordinates of a field id:

• fid = 284460
  echo FieldIdToCoords(fid)
  
  Result:
  14:58:01 Starting script
  14:58:01 Running line 1
  14:58:01 fid = 284460
  14:58:02 Running line 2
  14:58:02 460,355
  14:58:03 Script stopped

FindField

See also: FieldTypes

This function can find objects on the map within a specified radius of the searching city. You can for example use FindField to generate a list of all players near you, or all npcs level 10 within 20 miles, or whatever. The FieldTypes usable with FindField are linked above. The level is optional and can be omitted, or you may use "0" for any level. You can echo the results directly, or find and manipulate them from $result.

This example finds all the flats within a specified radius around your city, then echos the level of each:

• radius = 20
  execute "rescanmap {city.coords} {radius}"
  flats = FindField(city.x,city.y,radius,10)
  echo "There are {flats.length} flats around {city.name} ({city.coords})."
  
  label checkFlat
  thisFlat = flats.shift()
  if thisFlat == null end
  echo  "Coord: {FieldIdToCoords(thisFlat)} is a level {GetLevel(thisFlat)} flat."
  if flats.length goto checkFlat
  
  Result (debug off to reduce confusing/spam):
  17:02:45 SCAN COMPLETED: 422,319 radius 20
  17:02:46 There are 12 flats around MyCity (422,319).
  17:02:49 Coord: 410,321 is a level 3 flat.
  17:02:53 Coord: 414,320 is a level 5 flat.
  17:02:57 Coord: 414,327 is a level 4 flat.
  17:03:01 Coord: 419,331 is a level 9 flat.
  17:03:05 Coord: 421,306 is a level 1 flat.
  17:03:09 Coord: 422,309 is a level 3 flat.
  17:03:13 Coord: 423,301 is a level 2 flat.
  17:03:17 Coord: 423,308 is a level 1 flat.
  17:03:21 Coord: 424,301 is a level 10 flat.
  17:03:25 Coord: 424,311 is a level 3 flat.
  17:03:29 Coord: 425,302 is a level 9 flat.
  17:03:33 Coord: 425,306 is a level 1 flat.

This example gets a list of all npcs level 10 within 20 miles of your city, and then sorts them into an array of nearest to furthest from your city. Note - these are fieldIds not coordinates. You can turn the fieldIds into coordinates using FieldIdToCoords.

• list = FindField(city.x,city.y,20,12,10).sort(city.compareByDistanceToCastle)
  echo list
  
  Result:
  17:09:36 251614,250815,250014,250813,251613,250015,252412,254818,246020,250823,243621,247602,237221,244396

MapDistance

This function finds the distance between two sets of coordinates on the map.

This example finds the distance between your own city and target coordinates, rounded to 2 decimal places:

• targX = 123
  targY = 456
  distance = round(MapDistance(city.x,city.y,targX,targY),2)
  echo "Distance from {city.coords} to {targX},{targY} is {distance} miles."
  
  Result:
  15:36:13 Starting script
  15:36:13 Running line 1
  15:36:13 targX = 123
  15:36:14 Running line 2
  15:36:14 targY = 456
  15:36:15 Running line 3
  15:36:15 distance = 351.81
  15:36:16 Running line 4
  15:36:16 Distance from 460,355 to 123,456 is 351.81 miles.
  15:36:17 Script stopped

FormatDistance

This function finds the distance between two field ids and displays it in a nice readable format.

Basic example:

• echo FormatDistance(12345,23456)
  
  Result:
  15:27:46 Starting script
  15:27:46 Running line 1
  15:27:46 90.09 miles
  15:27:47 Script stopped

This example finds the distance between your own city and a target coordinates:

• targ = "123,456"
  targetId = GetFieldId(targ)
  distance = FormatDistance(city.fieldId,targetId)
  echo "Distance from {city.coords} to {targ} is {distance}.
  
  Result:
  15:29:56 Starting script
  15:29:56 Running line 1
  15:29:56 targ = 123,456
  15:29:57 Running line 2
  15:29:57 targetId = 364923
  15:29:58 Running line 3
  15:29:58 distance = 351.80 miles
  15:29:59 Running line 4
  15:29:59 Distance from 460,355 to 123,456 is 351.80 miles.

GetLevel

This function returns the level of whatever is located at a certain field id.

• echo "The object on the map at {FieldIdToCoords(1234)} is level {GetLevel(1234)}." //This is a level 1 desert at coords 434,1 on the map
  
  Results: 
  16:28:35 Running line 1
