Hi all.. here's my newest issue:

Entire code segment (from magic2.c):

//Undead barricade.. call_bonewall in ability.c
void spell_bonewall( int sn, int level, CHAR_DATA *ch, void *vo, int target )
{
	EXIT_DATA *pexit;
    ROOM_INDEX_DATA *room1;
	ROOM_INDEX_DATA *room2;
    char arg1[MAX_INPUT_LENGTH];
	int door1, door2;
	int wall1, wall2;
	bool dual_walls = TRUE;

	target_name = one_argument(target_name, arg1);

	if (arg1 == NULL || arg1 == "\0")
	{
		send_to_char ("In which direction would you like to cast this bonewall?\r\n");
		return;
	}

//not for npc's
	if (IS_NPC (ch))
	{
		return;
	}

    if (!str_prefix (arg1, "north"))
	{
		door1 = DIR_NORTH;
		door2 = DIR_SOUTH;
		wall1 = BONEWALL_DIR_NORTH;
		wall2 = BONEWALL_DIR_SOUTH;
	}
    else if (!str_prefix (arg1, "east"))
	{
		door1 = DIR_EAST;
		door2 = DIR_WEST;
		wall1 = BONEWALL_DIR_EAST;
		wall2 = BONEWALL_DIR_WEST;
	}
    else if (!str_prefix (arg1, "south"))
	{
		door1 = DIR_SOUTH;
		door2 = DIR_NORTH;
		wall1 = BONEWALL_DIR_SOUTH;
		wall2 = BONEWALL_DIR_NORTH;
	}
    else if (!str_prefix (arg1, "west"))
	{
		door1 = DIR_WEST;
		door2 = DIR_EAST;
		wall1 = BONEWALL_DIR_WEST;
		wall2 = BONEWALL_DIR_EAST;
	}
    else if (!str_prefix (arg1, "up"))
	{
		door1 = DIR_UP;
		door2 = DIR_DOWN;
		wall1 = BONEWALL_DIR_UP;
		wall2 = BONEWALL_DIR_DOWN;
	}
    else if (!str_prefix (arg1, "down"))
	{
		door1 = DIR_DOWN;
		door2 = DIR_UP;
		wall1 = BONEWALL_DIR_DOWN;
		wall2 = BONEWALL_DIR_UP;
	}
    else
    {
        send_to_char ("That is not a direction.\n\r", ch);
        return;
    }

	room1 = ch->in_room;

//no exit from room1
    if ((pexit = ch->in_room->exit[door1]) == NULL
		|| (room2 = get_room_index (pexit->u1.to_room->vnum)) == NULL)
    {
        send_to_char ("No one can go there anyway.\n\r", ch);
        return;
    }

//no exit from room2
    if ( (!room1->exit[door1]) || (!room2->exit[door2]) )
    {
		dual_walls = FALSE;
    }

//already wall1 in room1
	if (get_mob_vnum_room(ch, wall1))
	{
		send_to_char("There is already an undead barricade constructed in that direction!\r\n", ch);
		return;
	}

//already wall2 in room2 START
	char_from_room( ch );
	char_to_room( ch, room2 );
	if (get_mob_vnum_room(ch, wall2))
	{
		dual_walls = FALSE;
	}
   char_from_room( ch );
   char_to_room( ch, room1 );


//call mobs.
	if (dual_walls)
	{
		call_bonewall (ch, wall1, room1);
		call_bonewall (ch, wall2, room2);
	}
	else
		call_bonewall (ch, wall1, room1);

	return;
}

It compiles fine, and everything works real good.. except if there is no "target" direction given.. it doesn't work properly…

Problem piece:

target_name = one_argument(target_name, arg1);

	if (arg1 == NULL || arg1 == "\0")
	{
		send_to_char ("In which direction would you like to cast this bonewall?\r\n");
		return;
	}

It doesn't "send_to_char ("In which direction……etc", and instead continues and ends up targeting 'north'…

Any suggestions?

For one check:

arg1[0] == '\0'

And where is "target_name" coming from? Is it just a floating variable within your spells file? I don't see it being passed into that function anyplace.

At the top of magic2.c:

extern char *target_name;

Thanks for the fix on that one Kline, seems to be working now!
