Cheat Engine

[Bytzz]

So im new to programing and this type of things, Im trying to compile and make my own CE, saw a few old post of how to do it but I have problems with the compilaton, I got rid of some problems but I dont find any answer looking for google and cant manage to find it myself.
I have a lot of C4242 errors when I try to compile [conversion from 'unsigned __int64' to 'UINT_PTR', possible loss of data] (Also got this with QWORD TO UINT_PTR)Looking for internet found that its a warning and not an error, but as I dont know much about programing not sure what I should do
Also Im getting a lot of C4013 errors, that as well saw that are warnings and not errors, I should try to solve them or leave them like that its okay?
I dont really want someone to take my hand and say me what to do, it would be cool if anyone can give me some hints so I can test and try, but I will probably end asking again, hopefully I won.
Sorry for my bad english but it isnt my native lenguaje and I dont practice often

*Update*
So got rid of c4013 and c4242 errors tho idk if I do it correctly at least now the compile doesnt give me any error there, not I have errors with some .obj files with the error LNK2019 and LNK2001 so found that for LNK2019 Its probably an error in a header file but cant figure out where
