BOLO: I bet you may/may not have known how to do this. Either way, if you copy cvars and rename them, KAC queries will only get the old value, while the client operates on the new value.

Also, there are mathlib functions to clamp angles. KAC checks that as well.

void HideCvar(const char* origCvarName, const char* defaultValue, int origFlags)
{
    ConVar* pCvar = g_pCVar->FindVar( origCvarName );
    if (!pCvar)
    {
        Msg("[MS] ERROR: Could not find cvar %s\n", origCvarName);
        return;
    }
    ConVar* pNewVar = (ConVar*)malloc( sizeof ConVar );     //Create new convar pNewVar

    memcpy( pNewVar, pCvar,sizeof( ConVar ));           //Copy old var into new var
    pNewVar->m_pNext = 0;                               //Link new var?
    g_pCVar->RegisterConCommand( pNewVar );             //register new var
    pCvar->m_pszName = new char[50];                    //rename old var

    char tmp[50];
    Q_snprintf(tmp, sizeof(tmp), "ms_%s", origCvarName);//rename to ms_[origCvarName]

    strcpy((char*)pCvar->m_pszName, tmp);               //LOL UNINITIALIZED MEMORY IS LAME
    pCvar->m_nFlags = FCVAR_NONE;                       //eh...

    new ConVar(origCvarName, defaultValue, origFlags, "BYPASSED CVAR"); // lol

    Msg("[MS] Successfully created cvar bypass %s from %s\n", tmp, origCvarName);
}
