What exactly are &attacker and &inflictor - entity ids? user ids? Of whom or what?

Attacker will be the entity/client id of the client attacking (or entity id if an l4d common-infected). Inflictor can vary from being same as the attacker, the ent id of a weapon, the ent of a projectile, or even something else.

For example, in TF2:

For instant-hit weapons, this will be the client id, and the weapon will be the one they are currently holding.
For the syringe gun and blutsauger, this will be the ent id of the weapon.
For other projectiles (flare, arrow, rocket, nade, sticky), this will be the ent id of the projectile. The weapon will be the projectile's owner.

Re: [EXTENSION] SDK Hooks 1.1 (Updated 11/03/09)

This crashes my windows server, a few seconds ingame

PHP Code:


		
			
public OnClientPutInServer(client)
{
    Damage[client] = GetConVarFloat(g_playermultiplier);
    SDKHook(client, SDKHook_OnTakeDamage, OnTakeDamage);
}

public OnEntityCreated(entity, const String:classname[])
{
    if (StrEqual(classname, "infected") || StrEqual(classname, "witch"))
    {
        SDKHook(entity, SDKHook_OnTakeDamage, OnTakeDamage);
    }
}

public Action:OnTakeDamage(victim, &attacker, &inflictor, &Float:damage, &damagetype)
{
    if(!GetConVarBool(g_enabled)) return Plugin_Handled; // is this thing even on?

    decl String:sWeapon[32], Float:mWeapon, Float:amountWeapon;
    GetEdictClassname(inflictor, sWeapon, sizeof(sWeapon));
    
    new bool:changed;
    new Float:changemulti = 1.0;
    new Float:globalmulti = GetConVarFloat(g_multiplier);
    
    if(globalmulti != 1.0) //check for a global damage multiplier setting
    {
        if(globalmulti == 0.0) damage == 0.0; //nullify setting?
        else changemulti += globalmulti - 1.0; //else add multi
        changed = true;    
    }
    
    if (attacker > 0 && attacker <= MAXPLAYERS)
    {
        if(Damage[attacker] != globalmulti) //check for a player specific multiplier setting
        {
            if (Damage[attacker] == 0) damage == 0.0; //nullify setting?
            else changemulti += Damage[attacker] - 1.0; //else add multi
            changed = true;
        }
    }
    
    if(GetTrieValue(trieWeapons,sWeapon,mWeapon)) // check for the gun multiplier setting
    {
        if (mWeapon == 0) damage == 0.0; //nullify setting?
        else changemulti += mWeapon - 1.0; //else add multi
        changed = true;
    }
    
    if(changed && damage > 0.0) damage *= changemulti; //add all multipliers if not nullified yet
    
    if(GetTrieValue(trieAmount,sWeapon,amountWeapon)) //check for gun damage amount setting
    {
        damage += amountWeapon; //add gun specific damage amount
        changed = true;
    }
    
    if(changed) return Plugin_Changed;    
    return Plugin_Continue;
}

Any ideas? Just crashes, no error messages.

Re: [EXTENSION] SDK Hooks 1.1 (Updated 11/03/09)

try this:

PHP Code:


		
			
    //GetEdictClassname(inflictor, sWeapon, sizeof(sWeapon));

    GetClientWeapon(attacker, sWeapon, sizeof(sWeapon));

Re: [EXTENSION] SDK Hooks 1.1 (Updated 11/03/09)

Also, add l4d2 support? Ive looked up the Virtual adresses for you, but i have no idea about the signature

Weapon someone is hit by is not always the weapon the attacker is still holding.

Re: [EXTENSION] SDK Hooks 1.1 (Updated 11/03/09)

I've dumbed it down a lot, and narrowed it down to the OnEntityCreated Hook crashing

PHP Code:


		
			
public OnClientPutInServer(client)
{
    SDKHook(client, SDKHook_OnTakeDamage, OnTakeDamage);
}

public OnEntityCreated(entity, const String:classname[])
{
    if (entity < MAXPLAYERS+1) return;
    if (StrEqual(classname, "witch", false) || StrEqual(classname, "infected", false))
    {
        SDKHook(entity, SDKHook_OnTakeDamage, OnTakeDamage);
    }
}

public Action:OnTakeDamage(victim, &attacker, &inflictor, &Float:damage, &damagetype)
{
    if(!GetConVarBool(g_enabled)) return Plugin_Handled; // is this thing even on?

    decl String:sWeapon[32], Float:mWeapon;
    GetEdictClassname(inflictor, sWeapon, sizeof(sWeapon));
    
    if(GetTrieValue(trieWeapons,sWeapon,mWeapon)) // check for the gun multiplier setting
    {
        damage *= mWeapon;
        return Plugin_Changed;
    }

    return Plugin_Continue;
}

The signature you posted (the l4d1 one) looks like it will probably work. It is found in the binary, so, try it.

Re: [EXTENSION] SDK Hooks 1.1 (Updated 11/03/09)

Tried putting the Entity Hook behind a 0.1 Timer and checking for a valid entity -

No dice. Still causes instant crash
