|map||a ds_map with the information to encode|
json_encode takes a ds_map that you have previously
created and encoded as a JSON string which you can then use as (for
example) part of an http_post_string()
call, or so it can be stored externally, written to a file.
NOTE: The hierarchal functionality of JSON is available through special ds_map and ds_list functions, so you are able to encode sub-lists and maps.
var hiscore_map, i, str;
hiscore_map = ds_map_create();
for (i = 0; i < 10; i ++;)
str = json_encode(hiscore_map);
get = http_post_string("http://www.angusgames.com/game?game_id=" + string(global.game_id), str)
The above code creates a ds_map and then loops through the name and score arrays, adding each key/value pair to the new map. Next, this map is encoded using json_encode and stored as a string in the variable "str". This string is then sent to a web server using http_post_string and the ds_map is destroyed to prevent a memory leak as it is no-longer needed.
