DXWrapper with ImGui (d3d9)

[lightyyt]

Is it possible to use DXWrapper with ImGui? (Preferably it's DX9 Backend)? And If so, how would I do it? Do I need to use something from the dxwrapper dll instead of the d3d9 dll which obviously doesn't exist in my project? (The project is kinda old and would be a hassle to port to newer versions of anything)

Yes. The debug version of dxwrapper already has ImGui built in. It just requires a setting EnableImgui to enable it.

What's the use case? What do you want to use ImGui for?

I just want to use it for some of my own Developer Tools. Does that mean I need to use the dxwrapper.dll file or the ddraw.dll?

I assume you are using dxwrapper for either Dd7to9 or D3d8to9 to covert the game to Direct3D9. dxwrapper already has a Direct3D9 wrapper that integrates ImGui. You can use the code I already have or you can copy my code to integrate it into your own wrapper.

Here is some of my code:

dxwrapper/d3d9/IDirect3DDevice9Ex.cpp

Lines 95 to 103 in 5a80bc9

	#ifdef ENABLE_DEBUGOVERLAY
	// Teardown debug overlay before destroying device
	if (Config.EnableImgui && ref == 1 && DOverlay.IsSetup() && DOverlay.Getd3d9Device() == ProxyInterface)
	{
	ProxyInterface->AddRef();
	DOverlay.Shutdown();
	ref = ProxyInterface->Release();
	}
	#endif
