rwx!

rwx! is a class that wraps the D3D11 API to make drawing internally easier. It achieves this level of functionality by:

• Automatically hooking IDXGISwapChain::Present through a mixture of signature scanning and/or VMT manipulation
• Dynamically resolving pointers to important Direct3D 11 interfaces

How to use?

Before using the rwx! render class, it must be initalized. Please note that rwx! should only be used in dynamic link libraries (DLLs).

// Renderer::Renderer(const wchar_t* process, void* present_replacement) 
const auto renderer = std::make_unique<Renderer>(L"RustClient.exe", hooks::hk_present);

const wchar_t* process - The name of the executable you wish to hook Direct3D 11 on. void* present_replacement - The function that will be used in the trampohline hook for IDXGISwapChain::Present.

Within your IDXGISwapChain::Present hook, you should call Renderer::init as fast as possible. If the function call succeeds, you can call Renderer::begin and begin rendering.

HRESULT __stdcall hooks::hk_present(IDXGISwapChain* _this, UINT interval, UINT flags)
{
	if (renderer::begin(_this))
	{
		// Begin drawing
		D3DXVECTOR2 center{ renderer->get_viewport() };
		D3DCOLOR color{ 255, 255, 255, 1 };
		center.x /= 2;
		center.y /= 2;
		
		renderer::draw_box({center.x - 100, center.y - 100}, {100, 100}, color, 1.0f);
	}

	return hooks::o_present(_this, interval, flags);
