Как исправить ошибку в скрипте?

Question

[Данил Афанасьев]

ПРивет всем. Вот приобрел на просторах ассет стора такой замечательный ассет под названием TRUE VK!
Купил. Сразу после экспорта юнити выдал ошибку! Все файлы из ассета кому надо тут: https://yadi.sk/d/nl0huRk93NXYwd

Данил Афанасьев: А текст ошибки кто писать будет? Раз ошибка при импорте, то хорошо было бы ещё и версию юнити написать.

[Данил Афанасьев]

Даниил Басманов, Assets/TrueVK/Core/VK.cs(123,17): error CS0266: Cannot implicitly convert type `TrueVK.Core.Permissions' to `int'. An explicit conversion exists (are you missing a cast?)

Версия 5.6.1f1

Answer 1

Код немножко странный, ну да ладно.
Замените это:

var settings = 0;
foreach (var permission in permissionsArray)
{
    settings += permission;
}

На это:

var settings = 0;
foreach (var permission in permissionsArray)
{
    settings += (int) permission;
}

После этого должно скомпилироваться.
