Mental exercise:
cast spell at target <argument>
command name seperator vict optional arguments
[_CMD_] [_____________arg________________________]
Okay..
first we look for a spell name... we could have two, or more word
spells. Since we dont' have a delimiter (like double quotes), we can't use
the built in function 'one_word', instead we have to assume much trouble,
and use at.
--random mailer code --
char *at,*scratch,*dup;
char *spell_name, *vict_string, *opt_string;
int spell_number;
/* make a duplicate of arg since strtok alters string just in case */
dup=strdup(arg);
if(at=strstr(dup,"at")) { /* good we found an at */
spell_name = strtok(dup," ");
while(dup != at && *spell_name && *dup &&
((spell_number=find_skill_num(spell_name)) > 1 &&
find_skill_num(spell_name) < MAX_SPELLS)) {
scratch=strtok(NULL," ");
strcat(spell_name,scratch);
}
} else {
send_to_char("Syntax is : cast <spellname> <target> [options]\r\n",ch);
return;
}
if(spell_number < 1 || spell_number > MAX_SPELLS) {
send_to_char("Syntax is : cast <spellname> <target> [options]\r\n",ch);
return;
}
/* great, we have the spell number, now for the victim (remove at first) */
strtok(NULL," "); /* throw out 'at' */
vict_string=strtok(NULL," "); /* grab the vict_string */
opt_string=strtok(NULL," "); /* grab the options string */
/* put in the normal rest of cast i'd suppose */
Now, this may be wrong, cause i'm tired, and can't figure
out how to get a car to the auto shop this early in the morning, without
transportation back. I'm sure theres errors, or even an easier way to do
it, but this is pretty dry.
