Getting started with internals.

I've been making external cheats exclusively since I've been making cheats, in C# and C++. I don't like to copy/paste since I actually want to learn. I guess I just don't know where to start with making internal cheats. I get there are a lot of sources to look at, but I don't really know what I'm looking for in them lol. I've googled and searched mpgh/uc, but can't seem to find anything about the first steps towards making an internal cheat. So I'm hoping I can get some help with that, any little bit of information or just point me in the right direction would be awesome.

Also on a side question, can injectors be detected? I'm asking since I don't know if i should try to make my own injector as well.

Injectors can be detected, it's really easy to write your own (or paste). Use a CSGO internal base. Really helps

You could use for example the base from MarkHC. or you could google "coding your first hack", theres a pretty easy tutorial in UC to understand to concept, altough it doesnt work. To make it work, you first have to get and initialize the ICvar pointer Now you can do something like cvar->ConsolePrintF("Test)
Also, it should be .dll, but somehow that counted as a link and i could not post it.
