Хорошо, вот что я хочу. До сих пор он показывает карту с местоположением пользователя
и он находит точное местоположение, которое указано на этикетке ... правильно, если я делаю что-то не так ..
Что я хочу сделать, это запустить видео, когда пользователь достигает определенного места ...
ИАМ приближается, верно?
