描述

This function will clear the (previously created) ds_map of all key/value pairs, but it will not delete the ds_map itself from memory. For that you should use the function ds_map_destroy.

语法：

ds_map_clear(id);

返回：

N/A（无返回值）

例如：

if global.new_game
   {
   ds_map_clear(inventory);
   ;

The above function will check a global variable to see if it is true and, if it is, then the ds_map indexed in the instance variable "inventory" will be cleared of all key/value pairs (but it is not destroyed).
