    pygame.display.flip()
    screen.fill(screencolor)

这是我正在处理的一个小项目的代码但由于某种原因我收到了这个错误：

File "C:\Users\Isaac\Desktop\python kick\game\game.py", line 186, in <module>
screen.blit(image, imagerect)
TypeError: invalid destination position for blit

对我的问题有任何见解？我一直在测试和搜索。

Answer 1

你应该screen.blit(image, (x coordinate, y coordinate))通过矩形而不是坐标。如果您想使用矩形中的坐标，请self.rect.x和self.rect.y。

为什么我收到错误？ Pygame blits
