LUA Reversing need help

[Pete550]

Hi

I am looking for the flag LUA_IsSwimming and need some help.
reversed with IDA:

test    dword ptr [eax+0B00h], 200000h
jz      short loc_460159

So in C#:

public bool IsSwimming
        {
            get
            {
                return (Memory.Read<uint>(ObjectPointer + 0xB00)) & 0x200000) != 0;
            }
        }

Now i get Ingame this Value for:
not Swimming
(ObjectPointer + 0xB00) = x:
(342703568 + 0xB00) = 202179840

Swimming
(ObjectPointer + 0xB00) = x:
(342703568 + 0xB00) = 204276992

my question is how does it check with 0x200000 ?
2097152

It's basic math... How do you even able to reverse without knowing such basics...

Hi TOM_RUS

yes of course i can check it but sry my question was incorrectly worded.
i ask becouse IsMounted is also 0xB00 but with the checksum 0x10000000

test    dword ptr [eax+0B00h], 10000000h
jnz     short loc_460262

but the value doesnt change when mounted (its the same like IsSwimming and Toon is not swimming)
so something must be wrong with my memory reading.

[TOM_RUS]

but the value doesnt change

Values you provided above for IsSwimming says otherwise... (I mean
202179840=0xC0D0500 and
204276992=0xC2D0500)
