Я испытываю некоторые трудности с частью моего кода.Netlogo reort "Невозможно использовать GO в контексте наблюдателя, потому что только патч"
Я предполагаю, что это потому, что в части go я прошу процедуру (CACULATEWILANDATRAC), которая не начинается с "ask Patches",Однако продукт (CACULATEWILANDATRAC) предназначен для вычисления одной из собственных переменных патчей, поэтому запрос исправлений здесь не подходит.
Я все еще пытался решить эту проблему, помещая исправления запроса перед извлечением, но затем получаю другойошибка при запуске модели: «только наблюдатель может задавать ASK набор всех исправлений. ошибка, когда исправление 1079 509 выполняет ASK, вызванное (анонимная команда: [[the-Land-use the-Senario] -> ask patches [if count patches)with [the-Land-use]> the-Senario [set Willingstochange True]]]), вызываемый процедурой CACULATEWILANDATRAC "
Таким образом, проблема заключается в том, где вызывать процедуру CACULATEWILANDATRAC?Теперь это часть процедуры go, но это дает ошибку «Не удается использовать XXX в контексте наблюдателя, потому что только черепаха».
