Mycred feature: Changing point type.

Overriding the ARM_mycred_feature class like this works for me:

function arm_mycred_feature_override() {
	
	if (!class_exists('ARM_mycred_feature_custom') && class_exists('ARM_mycred_feature') && class_exists('myCRED_Hook') ){
		
		class ARM_mycred_feature_custom extends ARM_mycred_feature{
			
			function arm_get_mycred_points_by_user($user_id) {

				$mycred_current_balance = 0;
				if($user_id > 0 && function_exists('mycred_get_users_balance') ) {
					//$mycred_current_balance = mycred_get_users_balance( $user_id );
					$mycred_current_balance = mycred_get_users_balance( $user_id , 'my_custom_type');
				}
				return $mycred_current_balance;
			}
			
			function arm_update_mycred_points_by_user($user_id, $mycred_exchange_rate, $plan_id) {
				$return_val = false;
				if($user_id > 0 && $plan_id > 0) {
					$mycred_current_balance = $this->arm_get_mycred_points_by_user( $user_id );

					if ($mycred_current_balance > $mycred_exchange_rate){

						//$mycred_exchange_rate = -1 * ceil(((float)$mycred_exchange_rate));
						$mycred_exchange_rate = -1 * floatval($mycred_exchange_rate);

						$key = 'arm_mycred_point_key_' . $plan_id;
						$return_val = ($this->core->add_creds(
							$key,
							$user_id,
							$mycred_exchange_rate,
							$this->prefs[$key]['log'],
							$plan_id
						));
						//$return_val = true;

						$arm_debug_log_data = "UserID=".$user_id.", exchange rate=".$mycred_exchange_rate.", plan id=".$plan_id;
						do_action('arm_payment_log_entry', 'mycred', 'Update mycred points for user '.$user_id, 'armember', $arm_debug_log_data, $arm_debug_payment_log_id);
					}
				}
				return $return_val;
			}
		}
		
		global $arm_mycred_feature;
		$arm_mycred_feature = new ARM_mycred_feature_custom(array(), 'my_custom_type');
	}
}
add_action( 'mycred_load_hooks', 'arm_mycred_feature_override' , 999);

Not super safe incase there’s an update to the module and these functions in particular.
