DX9 ImGui unresponsive

[vars1ty]

The DirectX9 ImGui doesn't react nor detect proper mouse position in the same game as in #132.
It logs the position as "100, 100" and never recognizes any change, apart from sudden 1-frame drops to like 0, 0.

Code is the sample code from examples.

I can't work on this at the moment, but could you try deleting the first #[cfg] statement and the entirety of the second block here?

hudhook/src/hooks/dx9.rs

Lines 39 to 51 in bebcddc

	#[cfg(any(target_arch = "aarch64", target_arch = "x86_64"))]
	let wnd_proc = std::mem::transmute::<_, WndProcType>(SetWindowLongPtrA(
	renderer.get_hwnd(),
	GWLP_WNDPROC,
	imgui_wnd_proc as usize as isize,
	));
	#[cfg(target_arch = "x86")]
	let wnd_proc = std::mem::transmute::<_, WndProcType>(SetWindowLongA(
	renderer.get_hwnd(),
	GWLP_WNDPROC,
	imgui_wnd_proc as usize as i32,
	));

So that only this part remains:

hudhook/src/hooks/dx9.rs

Lines 40 to 44 in bebcddc

	let wnd_proc = std::mem::transmute::<_, WndProcType>(SetWindowLongPtrA(
	renderer.get_hwnd(),
	GWLP_WNDPROC,
	imgui_wnd_proc as usize as isize,
	));

Let me know if that fixes things; in that case, please open a PR so I can merge that in.

Hi, sorry for the late response, been busy.
I tried that just now, and it makes no difference from what I can tell.
The game in question is an offline RPG which does some very weird hacky things to its window, here it is if you'd like to take a look when you've got the time: https://archive.org/download/star-stable-win-iso-en.-cz.-fi.-hu.-de.-no.-se_202011/Star_Stable_Win_ISO_EN.CZ.FI.HU.DE.NO.SE.zip

No worries!

In all honesty, I'm not sure we should support programs which have weird unintended usages of the windows API, sounds like a game of cat and mouse against an API surface which is already difficult to work with. I'll give it a try though!
