Я использую следующий код, просто чтобы нарисовать спрайт и установить границы экрана. И к этому спрайту я создаю тело и добавил определение тела к телу. А затем я использовал физический соединитель для объединения спрайта. и тело. Но я не могу видеть, как тело движется. В результате я получаю только спрайт на экране, но тело и его свойства не были интегрированы в спрайт. Может кто-нибудь пройти код, который я написал, и поправьте меня Я следовал всем правилам, доступным в примерах,
