Hey everyone,

As I am trying to add an old multiclass code from Lost Prophecy files. To the 1.9.3 smaug mud.h file I notice that I cannot find the exact location of the first changes.

It states:
in mud.h

to char_data below

sh_int class;
add
sh_int dualclass;

Add to your defines:
#define IS_DUAL(ch) ((ch)->dualclass > -1)

change IS_VAMPIRE

#define IS_VAMPIRE(ch) (!IS_NPC(ch) \
&& ((ch)->class==CLASS_VAMPIRE \
|| (ch)->dualclass==CLASS_VAMPIRE))

Add the following prototypes in:

bool DUAL_SKILL args((CHAR_DATA *ch, int sn));
int dual_adept args((CHAR_DATA *ch, int sn));
int find_skill_level args((CHAR_DATA *ch, int sn));
int hp_max args((CHAR_DATA *ch));
int hp_min args((CHAR_DATA *ch));
bool use_mana args((CHAR_DATA *ch));


When I look in mud.h I do not see a reference that looks like:

sh_int class;
under a char_data field. Is it possible to still add
multiclass to the new version or am I not seeing where the proper field is?

If anyone has attempted this recently and can give info it would help me greatly.

-------
Could this be referring to the this section of mud.h

In the Github version at line 2163 there is a “short Class” field which is what they would be referring to:

https://github.com/Arthmoor/SmaugFUSS/blob/master/src/mud.h#L2163

The instructions you found must have had “sh_int” (short integer) as a typedef. “short” is more normal.

Note that “class” is a reserved word in C++ which is why it is capitalized as “Class” unlike most of the other variable names.

Yeah, it looks like they changed from C to C++ in 1.6 and renamed a bunch of things because of that:

https://github.com/Arthmoor/SmaugFUSS/commit/187e5d7f19ec31719b030296f3bd479f06502d9a#diff-0bdc8797a7da6e7e9d8e1713622c827ad00b5e33c9f820a5169d0ee3a72e2794R2145

Like Nick says, start with just replacing all instances of “sh_int” with “short” and “class” with “Class” in your instructions and in the code you want to add.

Ok I made it past a few of the steps with no problem so far.. This would seems like it is written differently though. What are your thoughts about this - looking at my version it seems something has changed.

In update.c, within advance_level find and change:

add_hp = con_app[get_curr_con(ch)].hitp + number_range(
class_table[ch->class]->hp_min,
class_table[ch->class]->hp_max );
add_mana = class_table[ch->class]->fMana
? number_range(2, (2*get_curr_int(ch)+get_curr_wis(ch))/8)
: 0;

Into:


add_hp = con_app[get_curr_con(ch)].hitp + number_range(
hp_min(ch),
hp_max(ch) );
add_mana = use_mana(ch) ?
? number_range(2, (2*get_curr_int(ch)+get_curr_wis(ch))/8)
: 0;



-------
MY VERSION:

void advance_level( CHAR_DATA * ch )
{
char buf[MAX_STRING_LENGTH];
int add_hp, add_mana, add_move, add_prac;

snprintf( buf, MAX_STRING_LENGTH, "the %s", title_table[ch->Class][ch->level][ch->sex == SEX_FEMALE ? 1 : 0] );
set_title( ch, buf );

add_hp = con_app[get_curr_con( ch )].hitp + number_range( class_table[ch->Class]->hp_min, class_table[ch->Class]->hp_max );
add_mana = class_table[ch->Class]->fMana ? number_range( 2, ( 2 * get_curr_int( ch ) + get_curr_wis( ch ) ) / 8 ) : 0;
add_move = number_range( 5, ( get_curr_con( ch ) + get_curr_dex( ch ) ) / 4 );
add_prac = wis_app[get_curr_wis( ch )].practice;

add_hp = UMAX( 1, add_hp );
add_mana = UMAX( 0, add_mana );
add_move = UMAX( 10, add_move );



---- Ok I might understand it now.. looks like they cut the lines short when they wrote it? It should be as long as the ones in mud.h

It looks like your instructions wrap the lines in a weird way. It should compile though because, by and large, extra newlines don't matter in C. (It would in a #define).

Thanks for the support guys. You guys are great. I am going to try to finish the rest of it when I get home from work. I know I still have to make a multiclass command in game as well. Will let you know how it goes.

Thanks

Another step that doesn't look like it exists in 1.9.3 act_info.c

inside act_info.c inside do_practice find:

change

if ( ch->level < skill_table[sn]->skill_level[ch->class]
|| (!IS_IMMORTAL(ch) && skill_table[sn]->skill_level[ch->class] == 0) )
continue;

into:

if (( ch->level < skill_table[sn]->skill_level[ch->class]
&& !DUAL_SKILL(ch, sn) )
|| (!IS_IMMORTAL(ch) && skill_table[sn]->skill_level[ch->class] == 0
&& !DUAL_SKILL(ch, sn) ) )
continue;

---- I've been unable to find the mentioned line, I know
they are wrapped sentence i'll unwrap if i can just find what they are saying lol. My act_info.c looks like:

void do_practice( CHAR_DATA* ch, const char* argument)
{
CHAR_DATA *mob;
char buf[MAX_STRING_LENGTH];
int sn;

if( IS_NPC( ch ) )
return;

for( mob = ch->in_room->first_person; mob; mob = mob->next_in_room )
if( IS_NPC( mob ) && xIS_SET( mob->act, ACT_PRACTICE ) )
break;

if( argument[0] == '\0' )
{
int col;
short lasttype, cnt;
bool is_ok;

col = cnt = 0;
lasttype = SKILL_SPELL;
set_pager_color( AT_MAGIC, ch );

for( sn = 0; sn < num_skills; ++sn )
{
const SKILLTYPE *skill;
int normalSn;

// the first num_sorted_skills are sorted by type, so we don't want
// to index into skill_table -- that is sorted alphabetically -- so
// we need to do the following dance to check if we are in the
// sorted section or the unsorted section.
if( sn < num_sorted_skills )
{
skill = skill_table_bytype[sn];

// we are looping over the skills sorted by type.
// So, we need to get the normal sn as well.
normalSn = skill_lookup( skill->name );
}
else
{
skill = skill_table[sn];
normalSn = sn;
}

if( !skill || !skill->name || skill->name[0] == '\0' )
continue;

if ( strcmp( skill_table[sn]->name, "reserved" ) == 0 && ( IS_IMMORTAL( ch ) || DUAL_SKILL(ch, sn) ) )
{
if( col % 3 != 0 )
send_to_pager( "\r\n", ch );
set_pager_color( AT_MAGIC, ch );
send_to_pager_color( " ----------------------------------[&CSpells&B]----------------------------------\r\n",
ch );
col = 0;
}

if( skill->type != lasttype )
{
if( !cnt )
send_to_pager( " (none)\r\n", ch );
else if( col % 3 != 0 )
send_to_pager( "\r\n", ch );
set_pager_color( AT_MAGIC, ch );
pager_printf_color( ch,
" ----------------------------------&C%ss&B----------------------------------\r\n",
skill_tname[skill->type] );
col = cnt = 0;
}
lasttype = skill->type;

if( !IS_IMMORTAL( ch )
&& ( skill->guild != CLASS_NONE && ( !IS_GUILDED( ch ) || ( ch->pcdata->clan->Class != skill->guild ) ) ) )
continue;

The next half mentions mobs...

Template:codetag To make your code more readable please use [code] tags as described here.


Your posted code looks pretty rough if you don't do that.


Your problem is that a posting that says "change line X to read Y" for code that is years old probably won't work. The code base will have been updated, improved, and things moved around.

Your best bet would be to read the intention of the changes, and then replicate them as best you can.

Alternatively, just work out what you want to happen and just code it. So you want multiclass? What will that mean to the player? Will they get spells/skills from both classes? You would need to try to (say) use a spell from the second class, and then see what error message you get. Find that part of the code and change it to allow for the second class. And so on.
