Я использую синглтон GameManager для обработки некоторых общих задач, необходимых для моей игры.Одна из таких задач - загрузка отдельных игровых сцен.Когда игра запускается, любая отображаемая комбо сцена / слой отображается неправильно;похоже, что координаты, относительно которых расположены элементы, неверны.
Не имеет значения, какой слой я выберу - все они отображаются неправильно.Если вы нажмете кнопку и загрузите другую сцену / слой, а затем вернетесь к рассматриваемой сцене / слою, все отобразится правильно.Это происходит только на устройствах отображения сетчатки, поэтому я думаю, что это может быть связано с масштабированием, которое я установил для разных типов дисплеев в диспетчере игр.Тем не менее, изменение масштаба для дисплеев Retina разрушает вещи еще больше (слои слишком малы).
