ch_ret projectile_hit in fight.c :P

..and that's called by ch_ret ranged_got_target, which is called by ch_ret ranged_attack, which is called by whatever skill/spell you're using :P

Ok i have read through this peice of code a number of times and still dont make sence of where the damage values are comming from, tho i hazzard a guess that this is is what is happening,


 if ( !wield )       /* dice formula fixed by Thoric */
	dam = proj_bonus;
    else
	dam = number_range(wield->value[1], wield->value[2]) + (proj_bonus / 10);

that if the MOB is shot by the projectile then the damage done is the values from the projectile, otherways if your wacking the MOB over the head with your ranged weapon then the damage done is the values from the ranged weapon + some from the projectile??
Im not much of a coder, but just need to work out how its working so i can work out some sort of game balance for ranged weapons when i add in new types for guns, rocket launchers and the like.
If anyone can help me decifer this would be greatly apreciated.

If a weapon is wielded then do the weapon's damage. Otherwise do proj_bonus damage.

If you look above in your function:

    if ( projectile->item_type == ITEM_PROJECTILE 
        ||   projectile->item_type == ITEM_WEAPON )
    {
        dt = TYPE_HIT + projectile->value[3];
        proj_bonus = number_range(projectile->value[1], projectile->value[2]);
    }
    else
    {
        dt = TYPE_UNDEFINED;
        proj_bonus = number_range(1, URANGE(2, get_obj_weight(projectile), 100) );
    }

There you go...
