Adapt twinject to other games about twinject HOT 6 CLOSED

Definitely, as long as the game uses DirectX 9.0. th_d3d9_hook, which is the sub-component of twinject that handles DirectX hooking, should work in theory with any DirectX 9 game. It can hook the entry point regardless of whether the DirectX is loaded statically (link-time) or dynamically (LoadLibrary).
th_d3d9_hook hooks BeginScene, EndScene, and CreateDevice, so custom code can be run in each of these methods while exposing the underlying IDirect3D9Device.

If the game does not use DirectX 9.0, then adaptations must be made to the wrapper methods (such as Direct3DCreate9) to the appropriate methods in the other version.

Also note that the code containing th_d3d9_hook must be injected into the target game.

Good. As I was looking at twinject 1.2.86 release version and testing with Touhou 10, I could see it works perfectly. I've done a good job man.

So I'd like to integrate a simpler twinject version to my project, so that:

• Neither all that initial UI windows overlaying the game will be needed nor all that render targets
• The my own 'bot' will need to start feeding fake input when the game start playing.

Thanks, I'm glad it worked the way it's supposed to (I've never tested twinject on another system).

If you need to fake input too, that is a separate component (th_di8_hook). It only supports DirectInput8, supporting any other versions of DirectInput would require similar changes as I mentioned above with other versions of DirectX. If the game uses the Windows Event Loop to handle input, you can probably adapt the Windows Event Hook code used for the IMGUI integration.

If you want to integrate twinject functionality into your project there are a few major components you will need to consider:

Injection

This is the job done by the injector portion using Microsoft Detours to create the game process and inject the hook DLL, this code should be easy to abstract for your case since it is very generic.

Hooking

You also need to initialize the hooks so that the code trampolines are created and the detours are set, this should be done in the injected DLL right after injection (DllMain).

Frame processing

The code that the hook calls is in this file, and can be modified (you said you didn't need the IMGUI functionality or rendering, which is in d3d9EndHook). you will probably need to modify this code to suit your needs.

The input hooking is very generic, and probably doesn't need to be modified, you can check the method names should be fairly self explanatory.

You should be able to figure out how most of the components work by inspecting how they are used for Touhou games.

Such a great information!

Really thanks.
