Python-基于Pygame的小游戏(天空之战)（一）

news 2025/2/24 4:01:59

前言:不久前接触了Python的游戏制作的相关第三方库，于是学习了pygame的相关内容，想制作一款基于pygame的小游戏。因为还不太熟悉游戏制作和pygame，部分内容我参考了《Python-从入门到精通》这本书。那么好，话不多说，我们直接进入今天的Python学习之旅-制作基于Pygame的小游戏(天空之战)。

一：准备游戏相关图片

制作pygame小游戏天空之战时，我们需要事先准备好相关的图片（如自己的战机，敌机，子弹等），最好是png或jpg格式。我这里用的是Windows自带的"画图"功能来制作自己的战机，敌机，子弹等图片，大家可以自行制作（需要我的原图片的话私信我发也行）。（如下所示）

敌机图片

战机图片

子弹图片

制作好图片好后我们将图片放在python项目下。（如下圆圈标注所示）
