В файле контракта Mentoring.sol возникли ошибки в методах breakMentoring, becomeMentor
Менторство нужно для повышения уровня персонажей
Есть студен и есть ментор
becomeMentor - вызываем если пользователь хочет обучать студенов. Он может указать стоимость обучения за 1 level
startLecture - вызывается когда студент нашел подходящего ментора для обучения
breakMentoring - пользователь перестают быть ментором
changeLevelPrice - меняем цену за 1 level
withdraw - вывод денег из игры
В коде контракта достаточно коментов, поэтому я думаю вам будет легко ориентироваться в нем
Нужно выпустить персонажей с помощью HEROES::mintTo
Нужны только токен и менторство в данный момент.
Выгружать в VM можно только их.
В миграции менторства нужно в ручную прописать адрес перед её выгрузкой.
migrate -f 1 —to 2
// Тут прописываем адрес
migrate -f 5 —to 5
Примерно так будет выгрузка выглядеть.
Шаги могут быть такие:
- Выгрузить два контракта
- Выпустить в токене HEROES персонажа (HEROES::mintTo)
- Вызвать для него глючные функции из Mentoring про которые Антон написал
Увидеть ошибку и постараться с ней разобраться
