Я только начинаю программировать, и у меня проблемы.XNA- возникли проблемы с перемещением спрайта назад к предыдущему экрану
Мне нужно иметь возможность перемещать изображение 64x64 (челнок1) через 4 места. Я настроил его как квадрант I, квадрант II, квадрант III, квадрант IV. Пока я могу перейти от квадранта I к квадранту II и от квадранта I к квадранту IV, но я не могу вернуться. Спрайт/изображение просто отключается от экрана. Любая помощь будет принята с благодарностью.
Это то, что я до сих пор:
