Помогите Пример кода как использовать RCON

[XjCyan1de]

Хотел бы посмотреть пример кода как можно выполнять RCON команду на другом сервере, гугли не нашёл

По RCON у меня подключается, а вот команду say Hello World не отправляет.
Погуглил и всё таки нашёл api для RCON: https://github.com/Kronos666/rkon-core
Но всё равно спасибо. Тема закрыта
