python - TypeError : argument 1 must be pygame. Surface, not pygame.Rect 在我的 Python 游戏中

Question

好吧，所以我正在尝试制作一个可以在屏幕上跳转的矩形，但是每当我运行该程序时，我都会收到此错误:

Traceback (most recent call last):
  File "Z:/Programming Projects/Learning/Basic Game.py", line 102, in <module>
    drawGameWindow()
  File "Z:/Programming Projects/Learning/Basic Game.py", line 72, in drawGameWindow
    win.blit(player.sprite, player.x_position, player.y_position)
TypeError: argument 1 must be pygame.Surface, not pygame.Rect

我明白这是什么意思，我不能使用 Rect 来 blit 和图像到窗口，而且我必须使用 Surface，但我不确定该怎么做，即使在查阅了文档之后.我将如何解决这个问题？

错误是由与问题中的错误相同的问题引起的:Convert rectangle to surface in pygame - 这部分是重复的。

但要解决这个问题，还有一些事情要做:

blit()的第一个参数必须是 pygame.Surface第二个必须是位置。 position 是一个由 x 和 y 坐标组成的元组。

创建一个 Surface 而不是在表面上绘制矩形并用 RED 颜色填充表面:

player_sprite = pygame.draw.rect(win, RED, (player_x_position, player_y_position, player_width, player_height))

player_sprite = pygame.Surface((player_width, player_height))
player_sprite.fill(RED)

第二个参数是一个元组:

win.blit(player_sprite, player.x_position, player.y_position)

win.blit(player_sprite, (player.x_position, player.y_position))
