Question

我开始在pygame中创建一个新游戏。首先，我制作了游戏的窗口和背景。我制作了背景（bg和fg）。当我的角色精灵移动时，我将保留fg并保留第二个背景bg作为滚动背景。之后，我粘贴了之前的pygame项目中的代码，该项目只是一个简单的sprite角色，可以在背景前行走和跳跃。当我粘贴它时，窗口出现，仅显示我的背景，根本不显示我的精灵角色。它也没有引发任何错误。发生了什么？我的精灵只是隐藏吗？

pygame.quit()

Answer 1

我无法对其进行测试，但是如果您更好地组织代码，则应该看到运行了两个while循环。在第一个循环中，您仅显示背景。而且您永远不会结束第一个循环，因此它永远不会运行第二个循环，从而在背景上绘制精灵。您应该删除第一个循环。

pygame精灵不会出现
