如何在后台模拟对 DirectX 应用程序的鼠标点击？

Question

I need to send some mouse clicks to a DirectX application covered by other windows while doing stuffs in the foreground. To other applications I uses SendMessage and it works well, however it won't work with DirectX apps. SendInput doesn't make sense because it controls your cursor directly and requires the window to be foreground. I want it does that completely background. Is there a way to achieve this? Thanks!

UPDATE 20191226: Just discovered that the Nox Android emulator listens mouse click events on the parent window rather than the rendering window. PostMessage to the parent window solves my problem.

00151044 "NoxAppPlayer" Qt5QWindowIcon                 <--Outmost window
└─ ...
└─ 00151264 "ScreenBoardClassWindow" Qt5QWindowIcon    <--PostMessage mouse event to this window
   └─ 002A05EA "sub" subWin                            <-- Screen renders on this window
└─ ...

Finally I used a completely different method: using ADB provided in Android emulator. Just adb connect to the port which the emulator used and simplly adb shell input tap [x] [y] solves my problem.
