Так что для моей сцены у меня есть сценарий Item и Slot. Если сценарий Slot применяется к пользовательскому интерфейсу в GridLayoutGroup, он не читает, даже если он завис или нет. Однако, если объект Slot UI находится не внутри GridLayoutGroup, он отлично читается.
Ниже приведены сценарии. Сейчас я использую масштаб на 35 пикселей для тестирования.

}
