将密钥发送到 DirectX 游戏
本文关键字：DirectX 游戏 密钥 | 更新日期: 2023-09-27 18:32:55
我在发送密钥时遇到了一点麻烦。好像每当我想发送密钥它不起作用时。
我正在考虑发送字母字符（例如 T）以从示例中引入聊天，但是如果我将其写入枚举，则每当我使用它们时都不会发生任何事情。有什么想法吗？

似乎这个问题引起了很多观点，所以这是我之前做过的解决方案（我从一个站点收集了输入，并将其制作成枚举以便于使用。

您的代码未发送击键。它发送一条消息，指出密钥已更改，而无需实际发送输入。如果目标窗口仅查看消息并忽略实际的密钥状态，则这可能有效。DirectX 应用通常会注意实际的键盘状态，并忽略已发送的消息。
而是使用 SendInput API 将密钥注入输入流。在此级别注入的输入将经过正常的输入处理，并像真正的键盘输入一样。根据目标应用程序，您可能需要在 KEYBDINPUT 结构中设置扫描码，而不仅仅是虚拟键。这可能适用于 DX 应用。
有关详细信息，请参阅 MSDN 键盘输入概述中的模拟输入部分。
