Where you can find other functions - MRandyPE/Addon-Functions GitHub Wiki

To get all mangled function names, you can simple run 'objdump -d libminecraftpe.so | grep "_ZN"' in folder with libminecraftpe.so.

To automatically demangling, you can use http://creepworks.herokuapp.com/cpp/demangle.html, or other online tools.

Another way to find all of the functions is to use IDA which let's you decompile the libminecraftpe.so file with ease.
