Я видел вопросы, похожие на то, что я задаю, но они не совсем дают мне ответ, который я ищу. Я хочу, чтобы 5 экземпляров моих спрайтов отображались на экране и появлялись в разных местах. Однако по какой-то причине вместо 5 экземпляров каждый «экземпляр» спрайта увеличивает значения одного спрайта, который появляется на экране.
