Different payout amount for each role

Hey Gabriel, how can we have different payout for each role?
This code give to only one role:

add_action( 'mycred_init', 'mycred_pro_monthly_payouts' );
function mycred_pro_monthly_payouts() {

	if ( defined( 'DOING_AJAX' ) && DOING_AJAX ) return;

	$this_month = date( 'n' );
	if ( get_option( 'mycred_monthly_payout', 0 ) != $this_month ) {

		// Grab all users for the set role
		$users = get_users( array(
			'role'   => 'subscriber', // The role
			'fields' => array( 'ID' )
		) );

		// If users were found
		if ( $users ) {

			$type = 'mycred_default';
			$mycred = mycred( $type );

			// Loop though users
			foreach ( $users as $user ) {

				// Make sure user is not excluded
				if ( $mycred->exclude_user( $user->ID ) ) continue;

				// Make sure users only get this once per month
				if ( $mycred->has_entry( 'monthly_payout', $this_month, $user->ID, '', $type ) ) continue;

				// Payout
				$mycred->add_creds(
					'monthly_payout',
					$user->ID,
					10,
					'Monthly %_plural% payout',
					$this_month,
					'',
					$type
				);
			}

			update_option( 'mycred_monthly_payout', $this_month );

		}

	}

}

There’s a way to give different amount for each role?
And how to change this monthly to weekly?
