    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

对我的问题有什么见解吗？我一直在测试和搜索很长一段时间。

Answer 1

应该是 screen.blit(image, (x coordinate, y coordinate)) 您传递的是矩形而不是坐标。如果您想在矩形中使用坐标，它们是 self.rect.x 和 self.rect.y.
