fetch assigned points for custom post

Hey.

If you are looking to get a users points balance then this Codex documentation is a great place to start: https://codex.mycred.me/the-mycred-logic/.

Basically you can get a users balance either by using get_user_meta which WordPress provides or use i.e. the mycred_get_users_cred function which myCRED provides:

$point_type = 'mytype';
$balance = mycred_get_users_cred( get_current_user_id(), $point_type );

If you need to handle multiple balances you can also have a look at the mycred function.
