【问题描述】：
我删除了之前的帖子，因为有类似的帖子。我很感激，但是因为我对 pygame 非常缺乏经验（我实际上是上周开始使用它的），所以我无法确定代码的正面或反面。另外，我发现很难应用到我的游戏中。首先，我不需要它与移动的玩家角色相关，因为他们总是从设定的位置（400、450）移动。另外，当按下鼠标左键时，我最好需要它来执行此操作，但是如果使用键更容易，那很好。我根本不具备使用过去帖子并将其应用于我的程序的专业知识。谢谢。澄清一下，我的游戏将是一款类似于猎鸭的目标射击游戏。

【问题讨论】：
-
您想使用鼠标单击，但您甚至没有尝试在代码中使用
pygame.MOUSEBUTTONDOWN。而且您的代码中没有向任何方向射击的子弹。 -
顺便说一句：您可以将目标保留在列表中，然后您可以使用
for-loop 来创建它们、移动它们、绘制它们并检查与项目符号的碰撞 - 代码会更短。跨度> -
@Rabbid76 这个问题说明了我为什么转发。我真的不知道如何将这些其他解决方案应用于我的程序。我不懂语言。不要删除问题，也许人们可以建议不要使用光标瞄准，因为它太复杂了？
