It would be nice to have a repository of such signatures, like CS entity offsets in Alliedmodders wiki.

I think one thing that can be done with orpheu is to manage func_ladder so anyone can dynamically create ladders that will be managed by engine.

As Arkshine said, hlsdk is not enough and we need more specific sdk (CS, DOD, etc) to fully understand how to do things.

    {
        OrpheuMemoryReplace("engineString",0,"Connection accepted by %s^n","Welcome %s to porn server !!!^n")
    }

Does Orpheu actually changes that string on memory or just change pointers to a new stack of strings?
Because if it changes strings and the new one is larger than the first one, what happens with the original memory alloc? Could happen a memory alloc error?

Quim somehow your example doesn't work for me, it says

Memory object identifier type "string" is invalid

What is weird since I put

Code:

 {
    "name"        : "engineString",
    "library"     : "engine",
    "type"        : "string",
    "memoryType"  : "data"
}

@joropito : Already talked about that with Quim, I think I will start a page on the wiki. About the strings, it changes the strings so yes, like Quim has warned "you should not use replacement strings longer than the original.", because obviously you will overwrite the next area and you will get probably a crash.

@01101101 : Wait for Quim, it seems the type is not included yet. I'm not sure.

About the type "string" not being recognized, It seems that I didn't posted an update where I changed the type to "string". Before, the type was called "char []" but I made it "string" to be better looking. I'm adding some stuff to Orpheu I will post an update latter.

Will there be more tutorials about using Orpheu?
This helped me learn some about it, but I'm kind of lost as to what this module can do and how to use it.

I was making a tutorial of virtual functions and it was like 70 or 80% done and I was writing it for some hour and half and then my firefox crashed. If only I could have back that text. It had some 7 screenshots and will be a pain to remake.

That's why I use Chrome

When I write large posts, I always save a copy at least in notepad.
Even when I submit the post I have a copy... just in case.
