Я продолжаю получать ошибки для учебника UE4 FPS Раздел 3.1. Что я должен делать?

Question

Для следующих кодов я должен добавить снаряд и уметь стрелять им, но строки кода, предоставленные UE4 для этого, не компилируются. Всякий раз, когда я компилирую, он выдает несколько кодов ошибок. Ниже приведены коды, используемые для этого проекта.
