And next we wait for IDA to finish analyzing our ELF, this can take a few minutes, once done you'll see "idle" at the bottom left
After that is done, you'll go into Views, Open sub views, then click "Strings"
Once it's done loading the strings you need to press ALT+T or go to Search, then Search
And in that dialog box that will open you up, we will write "numPlayers" then hit enter or OK
It should then bring you to a string which contains numPlayers, but that's not what we want, we want just the whole string.
So, to get there, all you have to do is press CTRL+T or go to Search, then Search again, until you see just the whole string.
Once found, double click it. You'll then see something like this
Double click the sub_* on the right of your string (numPlayers), should bring you to something like this.
Once done, you'd want to scroll up until you see something like(Doesn't have to be exactly the same) this..
But what if you when you scroll up, it doesn't look similar to that? What do you do then?
You'll go back to the string, and click the part on the left near the address, then press X or right click and click "Jump to xref to operand"
After that, you'll get a dialog with all of these places where the string was referenced, we'd simply click each of them
and check to see if they look similar to that other screen shot from above. Luckily here it was the second one.
Once you find the correct one which looks similar to the one above, you found your address.
The first part that is highlighted is the size of G_Client (interval) and the second is the actual address.
And that's all for now!

It's not advanced, its basic. If people actually learnt what memory is, and looked more into the subject, stupid (not personal) tutorials like this, detailed to one situation wouldn't have to exist.
But...seeing as people can't seem to do that, good job!
