This isn't a sourcemod plugin, there's no smx file to give you. The "builds" page linked on the first post has links to the compiled extension for all platforms, though.

I'm having a server crash with my feeble attempts to learn how to use DHooks. I'm trying to hook the act of hitting a building with a wrench in TF2. I found the following:

CBaseObject::OnWrenchHit(CTFPlayer*, CTFWrench*, Vector)

My gamedata looks like this:

"Games"
{
    "tf"
    {
        "Offsets"
        {
            "OnWrenchHit"
            {
                "windows"    "356"
                "linux"    "358"
                "mac"    "358"
            }
        }
    }
}

And my actual code looks like this:

public OnPluginStart()
{
    AddNormalSoundHook(Hook_EntitySound);
    
    new Handle:temp = LoadGameConfigFile("tf2.blunderatts");
    
    if(temp == INVALID_HANDLE)
    {
        SetFailState("Why you no has gamedata?");
    }
    
    new offset;
    
    offset = GameConfGetOffset(temp, "OnWrenchHit");
    hOnWrenchHit = DHookCreate(offset, HookType_Entity, ReturnType_Void, ThisPointer_CBaseEntity, OnWrenchHit);
    DHookAddParam(hOnWrenchHit, HookParamType_CBaseEntity);
    DHookAddParam(hOnWrenchHit, HookParamType_CBaseEntity);
    DHookAddParam(hOnWrenchHit, HookParamType_Int);
    
    CloseHandle(temp);
}

public OnEntityCreated(entity, const String:classname[])
{
    if (StrEqual(classname, "obj_dispenser")
        || StrEqual(classname, "obj_sentrygun")
        || StrEqual(classname, "obj_teleporter"))
    {
        SDKHook(entity, SDKHook_SpawnPost, OnSpawnPost);
    }
}

public void OnSpawnPost(entity)
{
    DHookEntity(hOnWrenchHit, false, entity);
}

public MRESReturn OnWrenchHit(pThis, Handle:hParams)
{
    PrintToChatAll("Hit with wrench.");
    //PrintToChatAll("DHooksHacks = Building %d, Player %d", pThis, DHookGetParam(hParams, 1));
}

The moment an active building is struck with a wrench, the server crashes without even reaching the PrintToChatAll. I tested removing Teleporters from the list, and then the server wouldn't crash when hitting a Teleporter, even when having another building active. I've tried a few different Return Types and have put in the Handle:hReturn when necessary, but no dice. Given the specificness of the crash, it sounds like I'm on the right track. But I'm completely new to DHooks, so I just need a shove in the right direction.

Thanks in advance!

The last param is a vector not an int and the return type is a bool

[Blunderstab]

    hOnWrenchHit = DHookCreate(offset, HookType_Entity, ReturnType_Bool, ThisPointer_CBaseEntity, OnWrenchHit);
    DHookAddParam(hOnWrenchHit, HookParamType_CBaseEntity);
    DHookAddParam(hOnWrenchHit, HookParamType_CBaseEntity);
    DHookAddParam(hOnWrenchHit, HookParamType_VectorPtr);

public MRESReturn OnWrenchHit(pThis, Handle:hReturn, Handle:hParams)
{
    PrintToChatAll("Hit with wrench.");
    //PrintToChatAll("DHooksHacks = Building %d, Player %d", pThis, DHookGetParam(hParams, 1));
}

Changed to these things, same result.

Tried myself, can't get it to work without crashing either.

Its not a vector ptr it is a vector.

[Blunderstab]

There's no HookParamType_Vector though. What do I use for vectors? (And for the record, not adding this parameter or having it be HookParamType_Float crashes the server as well.)

[Dr!fter]

HookParamType_Object and set the size to 12 and pass by val

[Blunderstab]

That fixed it! Thanks a bunch. While I'm still learning this though, I'd really like to know why size is "12". I'd expect vectors to be "3" since they should be storing three numbers.
