Хранитель Каражана.

[Karazhan]

Здравствуйте.Так как к сожалению эвент Шахматы в рейде Каражан неработают,решил маленькую альтернативу предложить.Признаюсь сразу честно,взял скрипт https://github.com/scriptdev2/script...the_pallid.cpp
и решил переделать его.В Ядре и в СкриптДев2 я документацию прочел,стало уже понятнее.Копирайты сохранены,я уважаю чужое творение.
Мне непонятен только один метод это DoUseOrButton,в скрипте инстанса это есть,а для чтобы существо открывало эту дверь после своего уничтожения,примеров ненашел к сожалению.Прошу подсказать,где ошибка.
