参数 描述 permissions The permissions you want to have from the user.
With this function you can request additional read permissions for Facebook. These permissions are added (as strings) to a previously created ds_list which is then used in the function to send the request. The user must be successfully logged in (ie. they have called facebook_login) and the facebook_status should be "AUTHORISED" before you call this function. the functon returns a unique ID value for the request call or -1 if the request was not sent (for example, the user is not logged in).
This function will trigger an Asynchronous Social Event, which contains the ds_map async_load. This ds_map will be populated with various key/value pairs to report the success or failure of the request.
var permissions = ds_list_create();
request_ID = facebook_request_read_permissions(permissions);
The above code checks som eof the Facebook read permissions, and if the game has not requested them, a request is sent.
