--------------------------------------- | +| Debug Build | Сборка проекта с отладочной информацией | +| GDB | Подключение к работающему процессу | +| Breakpoints | Точки остановки | +| Backtrace | Анализ стека вызовов | +| Variables | Просмотр значений переменных | +| Game State | Проверка состояния игровой логики | +| Server Debugging | Отладка игрового сервера | + +--- + +## 🔧 Почему нужна
