MUD Coding

Hello. I installed a FirstMud server, and have modified it a bit. I want to get imms/res/vulns to weapon materials working, and have churned out some code. In handler.c I've got this:

Code:

immune_t check_material(CharData * ch, ObjData * obj, weap_material)
{
    immune_t immune, def;
    flag_t bit;

    immune = IMMUNE_NONE;
    def = IS_NORMAL;
    
    obj = get_eq_char(ch, WEAR_WIELD);
    weap_material = obj->material;
    if (obj != NULL)
    {
        switch (weap_material)
        {
            case iron:
            case silver:
            case gold:
                if (IsSet(ch->imm_flags, IMM_IRON))
                    def = IS_IMMUNE;
                else if (IsSet(ch->res_flags, RES_IRON))
                    def = IS_RESISTANT;
                else if (IsSet(ch->vuln_flags, VULN_IRON))
                    def = IS_VULNERABLE;
                else if (IsSet(ch->dire_vuln_flags, DIRE_VULN_IRON))
                    def = IS_DIRE_VULNERABLE;
                if (IsSet(ch->imm_flags, IMM_SILVER))
                    def = IS_IMMUNE;
                else if (IsSet(ch->res_flags, RES_SILVER))
                    def = IS_RESISTANT;
                else if (IsSet(ch->vuln_flags, VULN_SILVER))
                    def = IS_VULNERABLE;
                else if (IsSet(ch->dire_vuln_flags, DIRE_VULN_SILVER))
                    def = IS_DIRE_VULNERABLE;
                if (IsSet(ch->imm_flags, IMM_GOLD))
                    def = IS_IMMUNE;
                else if (IsSet(ch->res_flags, RES_GOLD))
                    def = IS_RESISTANT;
                else if (IsSet(ch->vuln_flags, VULN_GOLD))
                    def = IS_VULNERABLE;
                else if (IsSet(ch->dire_vuln_flags, DIRE_VULN_GOLD))
                    def = IS_DIRE_VULNERABLE;
                break;
                default:
                def = IS_NORMAL;
                break;
        }
    }

    switch (weap_material)
    {
        case (silver):
            bit = IMM_SILVER;
            break;
        case (iron):
            bit = IMM_IRON;
            break;
        case (gold):
            bit = IMM_GOLD;
            break;
        default:
            return def;
    }

    if (IsSet(ch->imm_flags, bit))
        immune = IS_IMMUNE;
    else if (IsSet(ch->res_flags, bit) && immune != IS_IMMUNE)
        immune = IS_RESISTANT;
    if (IsSet(ch->dire_vuln_flags, bit))
        immune = IS_DIRE_VULNERABLE;
    else if (IsSet(ch->vuln_flags, bit) && immune != IS_DIRE_VULNERABLE)
    {
        if (immune == IS_IMMUNE)
            immune = IS_RESISTANT;
        else if (immune == IS_RESISTANT)
            immune = IS_NORMAL;
        else if (immune == IS_VULNERABLE)
            immune = IS_VULNERABLE;
    }

    if (immune == IMMUNE_NONE)
        return def;
    else
        return immune;
}

In fight.c, the damage modifier is checked like so:

Code:

switch (check_material(victim, weap_material))
    {
        case (IS_IMMUNE):
            immune = true;
            dam = 0;
            break;
        case (IS_RESISTANT):
            dam -= dam / 3;
            break;
        case (IS_VULNERABLE):
            dam += dam / 2;
            break;
        case (IS_DIRE_VULNERABLE):
            dam += dam;
            break;
        default:
            break;
    }

In defines.h, I set up material types (I think):

Code:

typedef enum
{
    iron,
    silver,
    gold
}
weap_material;

And lastly, in proto.h, the check_material function is defined:

Code:

Proto(immune_t check_material, (ObjData * weap_material));

I've just begun coding, and I'm using the functions already in place, as well as whatever I can find on the net, to guide my modifications. I have managed to achieve most of what I've started, but right now the compiler complains that

Quote:

fight.c:1183: error: cannot convert `CharData*' to `ObjData*' for argument `1' to `immune_t check_material(ObjData*)'

The referenced line is the first one from fight.c:

Code:

switch (check_material(victim, weap_material))

I'd appreciate any help anyone could give me. Thanks in advance!

Your CharData is a string pointer and your ObjData is an object pointer. You can't do that without a Mixed array.
