Do anyone know Dumping Libunity.so file like Libil2cpp.so in readable format?

[bs6489570]

I have a game thats main game functions thats affect the game are in libunity.so.  The game has also libilcpp.so.  But in game collision wallhacks, fly hacks all are in libunity. 

 

Now i want to find the offset for them.  I have ida and radare2.  But they don't show me function name.  That why i am unable to find offsets. 

Is there any proper way to find offset from libunity.so. 

 

I don't want to stuck on normal trial and error fuzzy serach method that kills time.
