DWORD GameBase = 0x400000;
DWORD* SomePointer = (DWORD*)(GameBase+0x4C62FC);
DWORD SomeValue = *(DWORD*)(*SomePointer+0xC); // Change the variable
(SomeValue) type accordingly to what the value type is that you're
reading at 0xC

could anyone please explain what this code is doing..... btw DWORD =
unsigned int -thx for the help!!! (explain as simply as possible)

It is reading a pointer from a known address...

DWORD* SomeOtherPointer = *SomePointer+0xC

Then reading the value at SomeOtherPointer

DWORD SomeValue = *SomeOtherPointer

The first statement assigns the value 0x400000 to GameBase.

The second statement is best explained in parts: (GameBase + 0x4C62FC)
results in the value 0x8C62FC. The cast converts this value to a pointer
type (DWORD *). That converted value is assigned to SomePointer.

The third statement finds the DWORD value at that address (0x8C62FC) and
adds 0xC (decimal 12) to it. It then converts the value to a DWORD
pointer, and reads the DWORD at that address into SomeValue.

Basically, the code is looking for a pointer value at a certain offset
into an array. That pointer value points to a DWORD, and the code is
looking up that DWORD value and assigning it to SomeValue.
