Ok, this code is for a morph skill I added to my mud; it basically lets a
player mimic an object of their level or lower, anywhere in the game
world. It has the following restrictions:
-You cannot save, cast, or fight while morphed.
-You are still a player, so can't use object commands on a morphed player.
-At auto-save you are forced to reform (to avoid odd pfile names).
-When morphed, you are not parsed in as a true object is. This is because
I didn't want morph to stand up under careful inspection.
Now, this code is easily configurable for however you want it to work on
your mud. If you find bugs, or need help with this code, contact
Ferric@uwyo.edu. I realize this code could have been simplified, or made
more elaborate; feel free to make alterations as you see fit. I treat it
as a command for thieves/mages on my mud. Perhaps a spell would have made
more sense, but I like this.
Enjoy; feel free to drop me a line at ferric@uwyo.edu if you use this
code.

First:
-----------
At the top of: act_comm.c,
fight.c,
magic.c,
save.c, add:
void do_reform args( (CHAR_DATA *ch) );
----------
Next: Merc.h
----------
In merc.h find #define COMM_AFK. Under it add:
#define COMM_MORPH (bb)
/*I used Comm because it was open, and you can use any open flags instead
of bb.*/
---------
then: merc.h
---------
find: extern sh_int gsn_enhance;
and under it add:
extern sh_int gsn_morph;
---------
then: merc.h
---------
/*This is ugly code, and could be done nicer. But, it works! :) -Ferric*/
Find:
char * name; /*in struct char_data*/
and
char * description;/*same place*/
and add below each (respectively):
char * backup_name;
char * backup_desc;
--------
then: merc.h
--------
In struct pc_data find:
char * title;
add below it:
char * backup_title;
--------
Next: act_info.c
--------
Add the following bits of code. I used act_info.c for no real reason,
but you may as well add it there.
void do_reform(CHAR_DATA *ch)
{
/*This code is used to retake your shape. -Ferric*.
if(IS_NPC(ch))
return;
if(!IS_SET(ch->comm,COMM_MORPH))

send_to_char("You are in your origional shape.\n\r",ch);
return;
}
REMOVE_BIT(ch->comm,COMM_MORPH);
ch->name = ch->backup_name;
ch->pcdata->title = ch->pcdata->backup_title;
ch->description = ch->backup_desc;
act("$n regains $s real shape.\n\r",ch,NULL,NULL,TO_ROOM);
send_to_char("You retake your familiar shape.\n\r",ch);
}
void do_polymorph(CHAR_DATA *ch, char *argument )
{
OBJ_DATA *obj;
int number = 0, max_found;
int skill;
number = 0;
max_found = 200;
if(IS_NPC(ch))
return;
if ((skill = get_skill(ch,gsn_morph)) < 1)
{
send_to_char("You are unable to morph!\n\r",ch);
return;
}
smash_tilde(argument);
if (argument[0] == '\0')
{
send_to_char("Polymorph into what?\n\r",ch);
return;
}
if(IS_SET(ch->comm,COMM_MORPH))
{
send_to_char("You must wait until you regain your shape.\n\r",ch);
return;
}
/*Don't ask me why I duplicated this code.
But since it's already here, I'll leave it.
Shouldn't be a prob if you cut the next 3 lines.

Done!
------------
Ok, as I've said, this code could certainly used a clean-up. Basically I
wrote it, and when it worked, I never looked back. And if you should find
any bugs in this, *please* email me with them so that I can fix them up
and re-release this code. Last thing; you needn't credit me in any way
you don't want to, although an email to ferric@uwyo.edu letting me know
you are using it will certainly be appreciated, and might even encourage
me to release some more of my more interesting code.
-----------
Note
-----------
If you are using mahntor.are, obj #1336 (a golden altar) has no
description; so, any player morphing into it is effectivly super-invis.
A couple of fixes: either add a description, or up the level high enough
that it's impossible for anybody to morph into it.
------------
To-do list
------------
-change 'where' to be more accurate with this.
-allow a more efficient way for imms to see morphed chars.
-clean the code up a great deal.
-parse the name in so that it matches up w/ other objects.
-allow for (glowing) (humming) flags on chars morphed to appropriate
objects.
-fix tell so that you can tell to morphed players w/out knowing their
current shape.
So, thanks for your time/attention, and happy mudding/Admining.
