最近设计了一款简陋游戏的雏形
本帖最后由 孤星8 于 2024-6-7 16:42 编辑在命令行窗口下，执行我的程序可以用左键和右键移动太空船（其实只是^符号），暂时不能发射武器。
我是用汇编写的，用的GetKeyState来读取键盘。

作为一个web开发者，很敬重游戏开发者，哪怕只是雏形，而且还是汇编语言编写的，哈哈{:10_453:} 加油 simonzhd 发表于 2024-6-5 05:24

站长过奖了，你准备学Flutter用Xcode编译iOS应用更让我敬佩你的毅力。哈哈。 james007 发表于 2024-6-5 06:34
加油
谢谢james007，也期待你的作品。 看不太明白 蓝莓糖 发表于 2024-6-6 21:41
看不太明白
很是高兴得到蓝莓糖的重视。你是指源代码看不明白吧? 这个程序打开后中间只有一个^ 符号，可以左右移动，迟点希望可以完善它，射出子弹，再迟点可以有外星飞船，给玩家对准射击。中文有个名称，不知道是什么了，英文名有几个名称，泛称Alien Shooting game / Galaxy spaceship.... 总觉得会编程写码的人很牛。为你点赞！ green5 发表于 2024-6-7 13:03

很高兴得到绿姐的称赞！:D 本帖最后由 孤星8 于 2024-6-7 16:52 编辑
我上传了shooter.zip，内含一个文件shooter.exe，可以用Windows打开运行。(已扫描电脑病毒)
