Universal graphical and input hook for a D3D9-D3D12, OpenGL and Vulkan based games
💠 Please leave a Star to the repository ✅ if you liked it. ✨

Installation / How to use.

1. Create a .NET Framework >=4.6 Project: Open Visual Studio and create a new Console application targeting .NET Framework >=4.6.

2. Install RenderSpy via NuGet:

   • Package Manager Console:

     Open the Package Manager Console and run:

     Install-Package RenderSpy -Version 1.7.8

   • .NET CLI:

     If you prefer using the .NET CLI, run:

     dotnet add package RenderSpy --version 1.7.8

   • Visual Studio Package Manager GUI:

     • Right-click on your project in the Solution Explorer.
     • Select Manage NuGet Packages.
     • Search for RenderSpy.
     • Install version 1.7.8.

3. Write your hook code using RenderSpy, see Samples

4. Build your dll and inject it into the game process. you can use my projects : Unmanaged.Net Or NETBuilderInjection

Samples

Sample	Description
Universal.FPS.Counter	A Universal FPS Counter for games
RenderSpy.Imgui	Easily use imgui in your favorite game
d3d11 SpriteText Render	Create a window with sharDX and render text in directx 11 using SpriteTextRenderer

Features

Note: The objectives of the list that have: [❌] - It means I have no idea how to solve it.

It includes all the libraries you need to draw, RenderSpy after compilation joins all the dependencies using ILMerge which means it appears to offer hooks, it also offers all the libraries you need to draw your overlay.

• OpenGL.Net
• SharpDX and its Wrappers [SharpDX.Direct3D9 - SharpDX.Direct3D10 - SharpDX.Direct3D11 ... and more!!]
• MinHook.NET [For your custom hooks.]

RenderSpy when incorporating these libraries has a weight of approximately 5mb, but if you use Costura.Fody in your assembly the weight is considerably reduced to approximately 1mb.
