This should be able to create cheating plugins, right

UPDATE:

• DirectX 8 Support.
• WantCaptureMouse, WantCaptureKeyboard fixes.

 

 

Known Problems:

• Directx 8 doesn't support D3DRS_SCISSORTESTENABLE.
• You cannot take Imgui off screen in DirectX 8 version.

Wanted to point out that on device reset, you might get your whole client frozen. That happens because the imgui's objects aren't invalidated & created again.

To fix it, use Imgui's own implementations inside CGraphicDevice::Reset:

 

bool CGraphicDevice::Reset()
{
	HRESULT hr;
	if (FAILED(hr = ms_lpd3dDevice->TestCooperativeLevel()))
	{
		if (hr == D3DERR_DEVICELOST)
			return false;
		
		if (hr == D3DERR_DEVICENOTRESET)
		{
			__DestroyPDTVertexBufferList();
			ImGui_ImplDX9_InvalidateDeviceObjects();
			
			if (FAILED(hr = ms_lpd3dDevice->Reset(&ms_d3dPresentParameter))) {
				TraceError("Failed to reset device");
				return false;
			}
			
			m_pStateManager->SetDefaultState();
			if (!__CreatePDTVertexBufferList())
				return false;
			
			ImGui_ImplDX9_CreateDeviceObjects();
		}
	}
	
	return true;
}

Don't forget to include imgui.h and imgui_impl_dx9.h (or imgui_impl_dx8.h depending on what you're using)

Hi Mali, first of all, this is super cool, thank you. I noticed a problem with this.

If you click on ImGui window, you can't open ESC menu on Release client or directly close the game on Debug client using the X button of Metin2 window anymore.

Could someone please share some example menus and buttons? It would help code illiterates like me a ton to create new functionality.
