Dhooks 2.2.0-detours9 extension has something or codes related to collision?
That's nice!

I looked and there the signature is not correct for windows.
Try this one.

PHP Code:

\x55\x8B\xEC\x57\x8B\x7D\x0C\x85\xFF\x75 


One of the hardest signatures I've been looking for.

Edit: Works without errors

Spoiler

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <dhooks>

public OnPluginStart()
{
    GameData hData = new GameData("SomeData");
    
    Handle hDetour = DHookCreateFromConf(hData, "PassEntityFilter");
    if( !hDetour ) SetFailState("Failed to find \"PassEntityFilter\" offset.");
    if( !DHookEnableDetour(hDetour, true, detour) ) SetFailState("Failed to detour \"PassEntityFilter\".");
    delete hData;
}


public MRESReturn detour(Handle hReturn, Handle hParams)
{
    PrintToServer("Entity 1 %i Entity 2 %i", DHookGetParam(hParams, 1), DHookGetParam(hParams, 2));
    return MRES_Ignored;
} 


PHP Code:

"Games"
{
    "left4dead2"
    {
        "Functions"
        {
            "PassEntityFilter"
            {
                "signature"        "PassEntityFilter"
                "callconv"        "cdecl"
                "return"        "int"
                "this"            "ignore"
                "arguments"
                {
                    "a1"
                    {
                        "type"    "cbaseentity"
                    }
                    "a2"
                    {
                        "type"    "cbaseentity"
                    }
                }
            }
        }
        "Signatures"
        {
            "PassEntityFilter"
            {
                "library" "server"
                "windows"        "\x55\x8B\xEC\x57\x8B\x7D\x0C\x85\xFF\x75"
            }
        }
    }
}

Huh, that's strange. There's nothing wrong with how the gamedata is constructed yet the detour is somehow trying to grab something from a pointer that doesn't exist even if it's ignored. It might be a valid entity becoming invalid when that happens. I could be wrong but try adding a validity check for both entities.

[Peace-Maker]

That's a general problem with post-detours in dhooks. Check the paragraph about "Accessing parameter values in post-hooks" in the release post.

[cravenge]

If I can remember properly, getting/changing the parameters should be done in pre-detours right? And it goes for the same for return values in post-detours?
