Re: Orpheu: How to make signatures (of bytes)

It means you retrieve the first byte of the instruction (the mnemonic 'push', 'mov', etc., you see it in the above screenshot) and that's not something which will change at runtime.

Re: Orpheu: How to make signatures (of bytes)

Well, I don't have enough knowledge in assembly to affirm whether this opcode is static. As I said in the tutorial, it's easier to take just the first byte of each line until you have a unique...

Re: Orpheu: How to make signatures (of bytes)

I've restored the images but I should probably update the tutorial to simplify things.

Essentially, once you know how to display/retrieve bytes, it's just a matter to retrieve the first bytes of...

Re: Orpheu: How to make signatures (of bytes)

I said ONLY first byte, and disregarding everything else, so :

51 56 8B ? 8B ? ? ? ? ? 83 ? ? 89

Re: Orpheu: How to make signatures (of bytes)

Forget the picture.

Follow this rule, which is more simple :

- Always keep the first byte
- Disregard anything else.

Do that until you get an unique signature when checking in IDA.

What do you mean by "the rest of the functions" ?

Re: Orpheu: How to make signatures (of bytes)

InstallHostageManager() doesn't return. Inside it sets directly g_pHostages.

Re: Orpheu: How to make signatures (of bytes)

Here another way, can be useful if you want to support linux and don't want to make signatures :

#include <amxmodx>
#include <orpheu>
#include <orpheu_memory>
#include <orpheu_advanced>
...

Re: Orpheu: How to make signatures (of bytes)

It works for me.

#include <amxmodx>
#include <orpheu_memory>

public plugin_init()
{
new mod_numknown = OrpheuMemoryGetAtAddress( OrpheuMemoryGet( "mod_numknown" ), "int" );

Re: Orpheu: How to make signatures (of bytes)

Tell me what you want to retrieve exactly, I will have a better view of the issue, because dword_xxxx or sub_xxxx doesn't help much.

Re: Orpheu: How to make signatures (of bytes)

Better to start to 8B, then you would +2.

Your sig should start like : 8B ? ? ? ? ? etc..

Re: Orpheu: How to make signatures (of bytes)

You can either make a signature of this function sub_1D5B210, retrieving its address, then adding some bytes as displacement to point to the address of this var, or making a signature direcly on the...

Re: Orpheu: How to make signatures (of bytes)

You would need to retrieve its address from a function where it's used.

You should create a new thread in scripting help because your problem has nothing to do with this tutorial.

Re: Orpheu: How to make signatures (of bytes)

The header is : void SV_CountPlayers(int *);

So it doesn't return something, result is passed by reference.

Not sure if it will work, but you can try to hook as post, then using...

Re: Orpheu: How to make signatures (of bytes)

Spawn is a virtual function. Prefer the use of Ham, more simple. The tutorial is not for such functions since it doesn't require signatures.

1. Why what ? If you're talking about why my signature works is because you don't have really understood my tutorial and you don't have put enough "*" for instructions/value which can change. If you...

Re: Orpheu: How to make signatures (of bytes)

Don't remember the error exactly ; this file should be put inside functions/ at the root (not in a sub-directory).
If not about parsing, show your code so.

Re: Orpheu: How to make signatures (of bytes)

You forget , et put spaces when you should not in the signature :

Try :


{
"name" : "SV_SendServerinfo",
"library" : "engine",
"identifiers":
