c++ - 使用 Oblita/Interception 库发送鼠标点击/发送坐标？

Question

我目前在一些项目中使用 Interception 库，如果我能够在现有代码中发送坐标并模拟鼠标点击，它将非常有用。我知道当前库中有一些东西支持做这样的事情，但由于缺乏文档(以及与开发人员的联系)，我担心我可能永远无法实现我的目标。

到目前为止我唯一的线索是鼠标坐标函数使用真实的鼠标坐标(意味着将某个变量设置为 -1 会反转鼠标，诸如此类)但我希望能够将屏幕坐标传递给它反而。此外，它具有某些鼠标标志(INTERCEPTION_MOUSE1_DOWN、INTERCEPTION_MOUSE1_UP 等)，但在尝试使用 SendInput 传递这些标志后似乎失败了。

如果有人能提供任何帮助，那将是一件幸事，谢谢大家!

P.S - 我确实看到另一个问题，有人问了与此类似的问题，但仍然有些复杂，并且缺少一些信息。再次感谢。
