The CONCOMMAND is just an example, if you were to use it and do wazz_weapons tf_weapon_minigun 2 you would have a minigun that shoots rockets. Changes are instant but this method effects all weapons of that type. To have a per-weapon setup you should detour `CTFWeaponBase::GetTFWpnData(void)const` and return your own instance of CTFWeaponInfo... I guess.

Edit: Include weapon_parse.h from the HL SDK for the FileWeaponInfo_t class.

Also, <3 and :3

-------------------------------------------------------------------

0 - projectile_none (lowers ammo, does no damage)
1 - projectile_bullet (bullets)
2 - tf_projectile_rocket (rocket launcher)
3 - tf_projectile_pipe (grenade)
4 - tf_projectile_pipe_remote (sticky)
5 - tf_projectile_syringe (needlegun -- doesn't always work)
6 - tf_projectile_flare (flaregun)
7 - tf_projectile_jar (doesn't work)
8 - tf_projectile_arrow (huntsman)


-------------------------------------------------------------------

DO NOT CHANGE THE PIPEBOMBLAUNCHER'S PRIMARY FIRE. If anyone right-clicks the server crashes...
(You could use TF2Items to kill alt-fire on the stickylauncher, but why nerf it? =\)

-------------------------------------------------------------------

There are two groups of projectiles (as far as I'm concerned). Those which require force (2, 3, and 8), and those which don't. Those which require force (not sure how this works, haven't really looked) will drop straight down (so arrows -- 8 -- will shoot straight into the ground). The rest fire from any gun. Obviously, the guns from which these weapons originally spawn -- pipebomb launcher (stickies), grenade launcher (pipes), and huntsman (arrows) -- will shoot these weapons (and the others) fine. The arc appears to belong to the weapon, so with any luck it's a ctx attribute.

From what I've gathered (based on how these projectiles spawn) the reason for this is likely to be tied to "CBaseEntity::ApplyLocalAngularVelocityImpuls e". What this does isn't something I've looked into... but it's used by pipes and jars (which both arc). There's likely to be something similar for arrows and stickies, but I haven't looked yet.

in TF2 it doesnt seem to work ... here my console output:

wazz_weapons tf_weapon_minigun
Address: 10AFC8C0
Count: 44
Wrong number of args u slag
wazz_weapons tf_weapon_minigun 2
Done

no rocket-miniguns ... what could be wrong ?

[Wazz]

Changes still seem to work for me however I just tested it using a slightly different function.

PHP Code:

CON_COMMAND(wazz_replaceweapon, "Wazz Environment :: Weapon info replacing. Format <weapon1> <weapon2>")
{
    if (args.ArgC() == 1)
    {
        META_CONPRINTF("Wazz Environment :: Weapon info replacing. Format <weapon1> <weapon2>\n");
        return;
    }

    if (!g_pWeaponInfoDatabase)
    {
#ifdef _WIN32
        void *addr;
        int offset;

        if (!g_pGameConf->GetMemSig("ReadWeaponDataFromFileForSlot_SubCall_01", &addr) || !addr)
        {
            META_CONPRINTF("NULL 1\n");
            return;
        }

        if (!g_pGameConf->GetOffset("WeaponDatabase_Offset", &offset))
        {
            META_CONPRINTF("NULL 2\n");
            return;
        }
        
        g_pWeaponInfoDatabase = *(WeaponDatabase **)((uint32)addr + offset);
#else
        void *addr;
        if (!g_pGameConf->GetMemSig("m_WeaponInfoDatabase", &addr) || !addr)
        {
            META_CONPRINTF("NULL 1\n");
            return;
        }
        
        g_pWeaponInfoDatabase = (WeaponDatabase *)addr;
#endif
        
        META_CONPRINTF("Address: %p\n", g_pWeaponInfoDatabase);
        META_CONPRINTF("Count: %i\n", g_pWeaponInfoDatabase->Count());
    }

    if (args.ArgC() != 3)
    {
        META_CONPRINTF("Not enough args. Format <weapon1> <weapon2>\n");

        return;
    }

    const char *pszWpn = args.Arg(1);
    const char *pszSwap = args.Arg(2);

    int iIndex1 = g_pWeaponInfoDatabase->Find(pszWpn);

    if (!g_pWeaponInfoDatabase->IsValidIndex(iIndex1))
    {
        META_CONPRINTF("Invalid Name: %s\n", pszWpn);

        return;
    }

    int iIndex2 = g_pWeaponInfoDatabase->Find(pszSwap);

    if (!g_pWeaponInfoDatabase->IsValidIndex(iIndex2))
    {
        META_CONPRINTF("Invalid Name: %s\n", pszSwap);

        return;
    }

    char *pszClassname = new char[80];
    strncpy(pszClassname, g_pWeaponInfoDatabase->Element(iIndex1)->m_achClassname, 80);

    memcpy(g_pWeaponInfoDatabase->Element(iIndex1), g_pWeaponInfoDatabase->Element(iIndex2), sizeof(CTFWeaponInfo));

    // Player cannot switch to weapon if classname isn't preserved
    strncpy(g_pWeaponInfoDatabase->Element(iIndex1)->m_achClassname, pszClassname, 80);
    delete pszClassname;

    META_CONPRINTF("Done\n");

    return;
} 


[Tauphi]

with your your i get the following now:

PHP Code:

\extension.cpp(290): error C2039: 'm_achClassname' : is not a member of 'CTFWeaponInfo' 


maybe it does not work cos the weapon info struct is not correct?

[Wazz]

Ah, I rebuilt FileWeaponInfo_t because I didn't like its naming convention. http://wazz.ampaste.net/d76b20ba4

[Seta00]

Are changes to FileWeaponInfo_t replicated on TF2? Can somebody change iSlot/m_nBucket for me and see if it works?

[Wazz]

Doesn't look like it
