No one here is gonna answer you step by step guide on how to re-create the hack to the nearest update, and even if you do change all offset's the strings the source use's will most likely get you banned. First thing you should do is start watching some C++ tutorials. There are some really good tutorials on Youtube such as Bucky's, Second, find out what offset's are, watch some tutorials, in fact search up a Youtuber named FleepHacks, He show's his viewers a good amount of content teaching you how to find offset's on game's and he also show's you some good source and what you need to do to make these hacks. (It's not going to step by step give you instruction like i said before, that is where your brain comes in), Thirdly, Search MPGH or other forums for question that could possibly already be answered.
Good Luck, Jake
