Question

我最近得到了pygame，并且遇到了blitting某个矩阵的问题。该计划本身是一个（未完成）的长期战斗。当我运行程序并按下FIGHT（进入FIGHT模式）时，我应该将attackBarRect与attackLineRect一起移到左侧，但它不会显示。但是，一段时间后退出FIGHT模式，因此矩形在那里，但没有出现。我研究了blitting rect的问题，但只找到了带有错误信息的主题（我没有任何问题），以及backround对项目进行了blitted（为此测试不起作用）的事实。请帮我。完整代码：

                attackLineRect=attackLineRect.move(546,246)
                break
            if attackLineRect.right<304:
                attackPowerSelf+=attackPower
            else:
                attackPowerSelf-=attackPower
            attackLineX-=1
            attackLineRect=attackLineRect.move(attackLineX,attackLineY)
            screen.blit(attackBar,attackBarRect)
            screen.blit(attackLine,attackLineRect)
            pygame.event.pump()
            pygame.display.flip()

您需要大步向下移动attackLineRect向右和向右移动。

attackLineX = 546
attackLineY = 246

# This moves the rect to the right by 546 pixels and down by 246 px.
attackLineRect = attackLineRect.move(attackLineX, attackLineY)

尝试打印attackLineRect，您会发现它很快离开了屏幕。

将其更改为，例如move(-1, 0)，将其慢慢向左移动。

attackLineRect = attackLineRect.move(-1, 0)

此外，您的计划结构奇怪，我建议您在Code Review或Reddit发布该计划，以获取一些提示。但代码应该正常工作，因此首先解决问题并将完整的代码与图像一起发布。

您应该已经使用的一件事是pygame.time.Clock来限制帧速率，例如：

clock = pygame.time.Clock()

while True:
    # In each while loop call `clock.tick(30)` to limit the frame rate to 30 fps.
    clock.tick(30)

pygame中的Rect似乎在那里，但没有blitting
