ds_list_mark_as_map(id, pos);
| Argument | Description |
|---|---|
| id | The id of the list to mark. |
| pos | The position within the list to mark. |
Returns: N/A
This function will "mark" (or "flag") a given position within a
previously created ds_list as holding a previously created ds_map.
This functionality is designed only for use when encoding JSON
strings (which you can create using json_encode)
and the complimentary ds map
functions.
NOTE: Once a ds_list has had a value within it flagged as
another list or map, destroying the list will also destroy the
marked lists and maps too. This means that you do not have to
manually go through the list contents and destroy the marked data
structures individually before destroying the "parent"
list.
var sub_map = ds_map_create();
ds_map_add(sub_map, "player", player_array);
ds_map_add(sub_map, "enemy", enemy_array);
ds_list_add(j_list, sub_map);
ds_list_mark_as_map(j_list, 0);
The above code creates a ds_map and then populates it with two keys, each containing an array of values. This map is then added into the given ds_list, and the position "marked" as such so that it can be correctly encoded later.
