That's because argument is null... this is a timer function, remember . . . you don't always have data in the char*argument to the function! you have to retrieve victim from those temporary pointers you created, or, from the who_fighting call.

Besides... your argument handling in do_handseal is wrong. Look at what you do with arg2 and argument, and think about what the value of 'argument' is as you pass it in to the do_chidori function...

Ok, here's the full code as it is right now. Right now, I only get the 'They aren't here' messages, because the victim is NULL.

void do_chidori( CHAR_DATA *ch, char *argument/*, CHAR_DATA *victim*/)
{
	CHAR_DATA *victim = ch->victim_ptr;
//	CHAR_DATA *victim;
	switch (ch->substate)
	{
	default:
		if (ch->level <= 50)
		{
		send_to_char("You cannot perform Chidori\n\r", ch);
		return;
		}
		if ( (victim = get_char_world( ch, argument ) ) == NULL )
		{
			send_to_char( "They aren't here.\n\r", ch );
			return;
		}
		if ( argument[0] == '\0' && (victim = who_fighting(ch)) == NULL )
		{
        ch_printf( ch, "You can't seem to focus for Chidori.\n\r" );
        return;
		}
		else if ( argument[0] != '\0' && (victim = get_char_room(ch, argument)) == NULL )
		{
        send_to_char( "You can't seem to focus for Chidori.\n\r", ch );
        return;
		}
		if ( ch == victim)
		{
		ch_printf( ch, "Using Chidori on yourself? Are you suicidal?\n\r");
		return;

If you're going to paste code, you should probably paste all of it so that we don't have to play guessing games with what you left out. :-) If you omit stuff, who knows if it might be doing something wrong that we should know about as we read your code?

Yea, it misses a small part. I removed it because it took up quite a few lines, but doesn't affect the call to do_chidori. All it did was remove some affects if you had them on you

Very true, I was simply refering to this
void do_handseal( CHAR_DATA *ch, char *argument)
{
char arg1[MAX_INPUT_LENGTH];
//char arg2[MAX_INPUT_LENGTH];

argument = one_argument( argument, arg1 );
//argument = one_argument( argument, arg2 );

CHAR_DATA *victim;
victim = ch;

    if ( arg1[0] == '\0' )
    {
		send_to_char("&YWhat would u like to perform?\n\r", ch);
		return;
    }
    if ( !str_cmp( arg1, "mfbtobs" ) )
    {
		ch->victim_ptr = victim;
		do_chidori(ch, argument);
		return;
    }
}
All I meant was to get this to work would be to initialize(with the appropraite checks, of course) victim to who_fighting(ch) instead of ch. Though setting up ch->victim_ptr to who_fighting(ch) would be pointless here, and should just be done and checked in do_chidori anyways.


As to how the other was working... yeah, your right, it shouldn't have been. Looks like these are not full functions anyways, as the one above really does very little anyways except call do_chidori. I would assume, possibly erroneously, that there is more that is not posted.

The error I pointed out is one of syntax, not semantics:

void do_handseal( CHAR_DATA *ch, char *argument)
{
     char arg1[MAX_INPUT_LENGTH];
     // char arg2[MAX_INPUT_LENGTH];

     argument = one_argument( argument, arg1 );
     // argument = one_argument( argument, arg2 );

     CHAR_DATA *victim;
     victim = ch;

     // Where is the opening if statement here?
     else if ( arg1[0] == '\0' )
     {
          send_to_char("&YWhat would u like to perform?\n\r", ch);
          return;
     }
     ...
It shouldn't have even compiled to begin with.

The reason that it was working before and not now was this part
victim = who_fighting(ch)
This was reseting victim to the proper setting. You can put something like that back in.

I don't see how the 'old code' could work in the first place because it starts out with an else if - but where's the if?

It does have a victim = ch at the top, but if you look carefully you'll see that victim gets changed right afterwards - the victim = ch seems to be a useless statement.

Ahh, now I see what went wrong, lol. I'll try coding it in tomorrow, but I think you're right.
ty :)

Edit: hmm, didn't seem to solve the problem.
The old code was posted 1 post above the new code. The old 'code' was the old version of handseal, and it also had that victim = ch; in it.
But that didn't seem to make a difference, because the attack still hit the 'real' victim instead of ch.

I have a concern. You do victim = ch;, but then later you do ch->victim_ptr = victim. Thus, arent you pointing to your own structure? As in, ch->victim_ptr->name would be the same as ch->name? Seems rather pointless to point to yourself.

Also, what exactly is the "old" code? What you should do, is when they specify the name of the victim, do something like,

if ( (victim = get_char_world( ch, arg2 ) ) == NULL )
{
  send_to_char( "They aren't here.\n\r", ch );
  return;
}


This will then give a pointer to the correct person, and if that person isn't found it will tell you "They aren't here."

The problem is the fact that the CHAR_DATA *victim contains the same information as CHAR_DATA *ch.
Which is understandable because in the beginning of the handseal function, there is a 'victim = ch;'
I'm wondering why the old code is able to attack the victim, even with that 'victim = ch;' part.
So my question kinda is: "Why does the old code have a good 'victim' and the new code doesn't, as it has about the same code."

Ok, I made a new pointer (victim_ptr), and I can get CHAR_DATA's to the new function now. But it seems like there is no way to get the char data of the victim passed on. I don't know why, because in the old function, it didn't have anything extra, but it did target the victim.
I didn't change anything in the code (so didn't remove the messages and all)
Old Code:

void do_handseal( CHAR_DATA *ch, char *argument)
{
char arg1[MAX_INPUT_LENGTH];
// char arg2[MAX_INPUT_LENGTH];

argument = one_argument( argument, arg1 );
// argument = one_argument( argument, arg2 );

CHAR_DATA *victim;
victim = ch;

     else if ( arg1[0] == '\0' )
     {
      send_to_char("&YWhat would u like to perform?\n\r", ch);
      return;
     }
     if ( !str_cmp( arg1, "mfbtobs" ) )
     {
     if (ch->level <= 50)
      {
       send_to_char("You cannot perform Chidori\n\r", ch);
       return;
