Как я могу создать двухмерную прокрутку плитки в Pygame? ⇐ Python

[Anonymous]

Я создаю игру RPG, как и игра, однако, я абсолютно понятия не имею, как прокручивать карту, чтобы игрок был в центре. Любые другие предложения, которые у вас могут иметь, также будут высоко оценены! Спасибо за вашу помощь! Вот мой код: < /p>
