Hi

The enumerated Dlls and Symbols for the unity game is mainly showing the EXE file and mono.dll (using latest CE beta)
Managed Dlls are not showing up

having the code reversed using "JetBrains dotPeek", I have found many interesting functions that I want to hook in UnityEngine.dll

could someone plz tell me"
1) Why not all Dlls are showing up
2) is there a way to locate the dll and enumerate it
3) is there a way to do "foreign function interface" FFI in CE Lua on that DLL

My target is to locate the function in memory and call it with my parameters

Thanks

Edit:
I have just learned that Managed .Net Dlls are not native.
what are my options here?

1: The enumerate dll's and symbols window only shows dll's loaded using the windows dll load mechanism.
Mono doesn't use that mechanism to load dll's (as it has a way to load them nor non-windows systems, there's no need for it)

2: yes.
activate the mono features, and then go to dissect mono.
There you can find the dll you're interested in

3: I have no idea what you mean (I don't use official names). There are some functions available that allow you to load a new .net dll into the target domain and do stuff if you like.

If you mean editing an method, you could compile (JIT) a method you're interested in (there's a lua function for it in the monoscript.lua file and mono dissect window) and then edit the native code. (Or before it's jitted find the native code, and then edit the IL code )

yes, you could jit that metbod and then call it

you do need the class instance (in ecx) before you can call it though. (code injection on a method of that same class is the easiest)
