Adding clans to battle_check_target

[Tzuridis]

I want to edit battle_check_target which determines who the player can attack.

As it is now:

 

battle_check_target

//which has these definitions set for it

    BCT_NOONE       = 0x000000, ///< No one
    BCT_SELF        = 0x010000, ///< Self
    BCT_ENEMY       = 0x020000, ///< Enemy
    BCT_PARTY       = 0x040000, ///< Party members
    BCT_GUILDALLY   = 0x080000, ///< Only allies, NOT guildmates
    BCT_NEUTRAL     = 0x100000, ///< Neutral target
    BCT_SAMEGUILD   = 0x200000, ///< Guildmates, No Guild Allies

    BCT_ALL         = 0x3F0000, ///< All targets

    BCT_WOS         = 0x400000, ///< Except self (currently used for skipping if src == bl in skill_area_sub)
    BCT_GUILD       = BCT_SAMEGUILD|BCT_GUILDALLY,  ///< Guild AND Allies (BCT_SAMEGUILD|BCT_GUILDALLY)
    BCT_NOGUILD     = BCT_ALL&~BCT_GUILD,           ///< Except guildmates
    BCT_NOPARTY     = BCT_ALL&~BCT_PARTY,           ///< Except party members
    BCT_NOENEMY     = BCT_ALL&~BCT_ENEMY,           ///< Except enemy
    BCT_ALLY        = BCT_PARTY|BCT_GUILD,
    BCT_FRIEND      = BCT_NOENEMY,
    BCT_CLAN        = BCT_SAMECLAN|BCT_CLANALLY ///< **What I added**

I added BCT_CLAN at the bottom which would reference these variables? int literals?

BCT_SAMECLAN    = 0x300000 or whatever it would be, ///< Clanmates
BCT_CLANALLY    = 0x280000, ///< Clan allies

The purpose is to add BCT_CLAN to the conditional which determines if a player can attack someone:

if( !state ) //If not an enemy, nor a guild, nor party, nor yourself, it's neutral.
        state = BCT_NEUTRAL;
    //Alliance state takes precedence over enemy one.
    else if( state&BCT_ENEMY && strip_enemy && state&(BCT_SELF|BCT_PARTY|BCT_GUILD|**BCT_CLAN**) )
        state&=~BCT_ENEMY;

    return (flag&state)?1:-1;
}

///> I also added the **BCT_CLAN**

My question is how would I go about finding out what those (0x000000) values are for the same clan and clan ally. How was this figured out for the BCT_GUILDALLY & BCT_SAMEGUILD?
