Так что в основном я пытаюсь создать немного сложного (для моего уровня программирования) и пытаясь использовать kinect для запуска разных ничьих. Я так жаль этого большого кода, но ошибка медленно сводит меня с умаjava.lang.RuntimeException: java.lang.NullPointerException PROCESSING

Вы пытались использовать отладчик? – Biffen
@ Биффен У меня еще нет, как использовать отладчик в обработке? Спасибо за быстрый ответ! –
@ У вас есть объект под названием hotbox7? – robin
