Клиентская Entity не соответствует серверной

Собственно, делал я метательное копьё. И всё бы нормально, но вот как дело дошло до рендера, я заметил, что оно при выстреле улетает куда-то вправо вверх, притом после выстрела втыкается в землю именно там, где и должно втыкаться по-нормальному.
Я решил выводить координаты копья каждый тик. И получил, что координаты на сервере и на клиенте отличаются, причем чем дольше летит - тем больше отличаются, как будто направление выстрела на сервере и клиенте разные. В коде я не нашел различий между запуском стрелы на клиенте и на сервере. Почему так получается и как это исправить?
Код копья и рендерера был скопирован из стрелы Minecraft и немного изменен.

Вот я стреляю:

И вот они втыкаются(именно там, куда я стрелял):

Решение
Motion entity не может превышать 3.9D. В ином случае оно просто клампится до этого значения. Почему 3.9? Потому что майнкрафт синхронит моушн ентитей через short (умножая motion на 8000).
Фикс тут. (ну и из-за того, что хук либа доработана, можно вставлять хуки только в сами пакеты)

В теме хуклибы написано, как ею пользоваться.
Ну у меня нет проекта 1.8. Классы, которые нужно фиксить есть в той теме, что я скинул. Придется пошаманить ручками, если хочешь пофиксить.

Адаптировать этот код под 1.8 у меня не получилось. Пока что сделал немного костыльный вариант - просто уменьшил скорость полета копья.
Спасибо за помощь, может быть когда-нибудь я буду настолько пьян, чтобы сесть за этот фикс снова :LOL:
