Problems decompiling Unity game
I am trying to disassemble the game "Among Us" on mobile, which is written using Unity. It has also been obscured using IL2CPP. I have decompiled the APK into C# files, but they all either have nothing in them or have only a return value. They also have instruction offsets, but when I looked at some of the functions in assembly they only consisted of a ret instruction.
Example: Vending Machine Minigame Code
using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
using Il2CppDummyDll;
using UnityEngine;

Example: Vending Machine Code Enter in Assembly:
.method public hidebysig instance void EnterDigit(string s) cil managed
{
.custom instance void [Il2CppDummyDll]Il2CppDummyDll.TokenAttribute::.ctor() = ( 01 00 01 00 53 0E 05 54 6F 6B 65 6E 09 30 78 36 // ....S..Token.0x6
30 30 30 32 36 33 ) // 000263
.custom instance void [Il2CppDummyDll]Il2CppDummyDll.AddressAttribute::.ctor() = ( 01 00 03 00 53 0E 03 52 56 41 08 30 78 38 39 34 // ....S..RVA.0x894
41 34 30 53 0E 06 4F 66 66 73 65 74 08 30 78 38 // A40S..Offset.0x8
39 34 41 34 30 53 0E 02 56 41 08 30 78 38 39 34 // 94A40S..VA.0x894
41 34 30 ) // A40
// Code size 1 (0x1)
.maxstack 8
IL_0000: ret
} // end of method VendingMinigame::EnterDigit
How would I be able to see the functionality of the code (either in C# or in assembly)?
