В верхней части я добавил две новые статические переменные:
static int numofconversations;
static int oldnumofconversations;
Затем внутри статического метода GetWindow я сделал:
oldnumofconversations = numofconversations;
Затем внутри OnGUI:
if(oldnumofconversations != numofconversations)
{
m_Initialized = true;
oldnumofconversations = numofconversations;
}
Но при использовании точки останова, показывающей, что старые numofconversations всегда имеют то же число, что и numofconversations, при изменении числа в поле int.
