A Source Engine interface is an object the engine exposes at runtime through its CreateInterface function. Each interface is basically a versioned pointer to a class with a virtual function table, implemented inside engine DLLs such as client.dll or engine.dll.
If you want to hack CSGO using CreateInterface, this is the tutorial for you! In this guide we are going to learn all about the CreateInterface function for the purposes of CSGO hacking and how it can be leveraged to call DLLs like engine.dll and client.dll without having to reverse engineer everything from scratch. These DLLs are used in the source engine to call commonly used functions that we can then use as game hackers to interact with these DLL files to obtain pointers to objects in the game such as the client entity list to manipulate them more efficiently.
What you will learn:
What an interface is in the Source engine
How CreateInterface works in CSGO
Which DLLs export CreateInterface
How to get an interface pointer
Calling vtable functions like GetClientEntity
Read entity health and other data
Add CreateInterface to your DLL project
Simple CreateInterface implementation
Now we're going to define our GetInterface() function. We're going to change our return value to typedef void*. This is going to be a __cdecal* tCreateInterface function pointer type. The arguments are const char* name, int* pointer returnCode.
We are going to create another function called GetInterface() with a void* return value. This is going to call our CreateInterface function. We're going to pass in const char* dllname and const char* interfacename as arguments. Then simply add the rest of the code below to return the interface. I'm not including any error checking here, but you can certainly do that.
Now we're going to get the function. This is just a function prototype, which we're going to cast to a pointer to the CreateInterface() function. Then we're going to pass in a dllname because each DLL has its own set of interfaces that it can export. GetModuleHandle() is going to get the address of the handle to the DLL for each module. Then we're going to cast that to a tCreateInterface pointer and assign that value to CreateInterface.
We're then going to call CreateInterface passing in interfacename and &returnCode, and then we're going to return the interface pointer.
