Looking for ESP source code for reference.

I really liked the Gopnik ESP so I was wondering if anyone had anything like that or possibly had the source code for it. I am trying to make my own ESP for dead by daylight and I could really use reference material. I wont use the same source code but it would be nice. It can be old that does not matter. Thank you for your time. Also I wont charge money for this I am going to release it on here when its working. Thank you all for your time. Before someone asks I do know c++, java and objective c for coding so I do know code just not the hacking side of it.

There is a old hack, it included the dll, so you can look at the source code. Just google it Ring0 dead by daylight hack. Or maybe go ask Hure and Morritz directly.
