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):
