Alright, I wrote up a races code for my MUD that runs on tbaMUD 3.63. Since I have heavily modified my code I'm going to do my best to properly explain where certain things go. I can tell you use your best judgement. I did look at the TBA stock code so I was able to directly put things from it into there. Here goes.
Code:
1. make a file called race.c 2. add this: /************************************************************************** * File: race.c Part of tbaMUD * * Usage: Source file for class-specific code. * * * * All rights reserved.

Type cd .. and make :)

This is a bare races code. I didn't add any extra features for them. This is just to get you started. Also, I didn't touch the db.c file as I tend to always mess it up(Vatiken want to tackle that). Hopefully this transfers easily into stock tbaMUD.

10/30/2012 Edit: Fixed some small errors. Fixed dwarfs not being defined correctly for shops. Fixed instruction errors. Add how to add race to plrtoascii. Updating to snippets page.

Hmm... getting some errors in trying to compile after adding in this snippit. At first it was with act.informative.c, but got that fixed and now it's with dg_variables.c. it's having an issue with this part:

case 'r':
if (!str_cmp(field, "race")) {
if (subfield && *subfield) {
int ra = get_race_by_name(subfield);
if (ra != -1) {
GET_RACE(ch) = ra; // Error here snprintf(str, slen, "1");
} else {
snprintf(str, slen, "0");
}
} else
sprinttype(GET_RACE(ch), pc_race_types, str, slen); // Error here }
else if (!str_cmp(field, "room")) { /* in NOWHERE, return the void */

Here are the compiling errors.
dg_variables.c:972:13: warning: statement with no effect
dg_variables.c:972:26: error: expected expression before ‘=’ token
dg_variables.c:978:22: error: expected ‘)’ before ‘;’ token
dg_variables.c:978:22: error: too few arguments to function ‘sprinttype’

I noticed that there were a few instances of 'c' being used instead of 'ch' so I changed those. Errored out before and after the change. (e.g. GET_RACE(c) instead of GET_RACE(ch))

Looks like a missing ; or {}. Something similar to what you had to do to fix the previous post. Doublecheck everything and post using the code blocks so it is easier to read. You might need to include a few more lines before the error to catch the bad formatting.

Please post the fixes so we can correct it for the next person.

case 'r':
if (!str_cmp(field, "race")) {
if (subfield && *subfield) {
int ra = get_race_by_name(subfield);
if (ra != -1) {
GET_RACE(ch) = ra; // Error here snprintf(str, slen, "1");
} else {
snprintf(str, slen, "0");
}
} else
sprinttype(GET_RACE(ch), pc_race_types, str, slen); // Error here }


It looks like it may of copied wrong. It should look exactly like this:
Code:
case 'r': if (!str_cmp(field, "race")) { if (subfield && *subfield) { int ra = get_race_by_name(subfield); if (ra != -1) { GET_RACE(c) = ra; snprintf(str, slen, "1"); } else { snprintf(str, slen, "0"); } } else sprinttype(GET_RACE(c), pc_race_types, str, slen); }

Also change the instances back to c, in dg_variables uses c as the target I believe.

Hmmm... yeah, I double-checked and it looks exactly like that.

Oh yeah, thanks for saying that Rumble, I would've forgotten otherwise. There were a couple errors, one in act.wizard.c in which #include "race.h." should have been #include "races.h" (to match the races.h file I have). Same thing in the interpreter.c.

Here's case 'r' and I also included case 'q' and the else if that comes after case 'r'.
Code:
case 'q': if (!IS_NPC(c) && (!str_cmp(field, "questpoints") || !str_cmp(field, "qp") || !str_cmp(field, "qpnts"))) { if (subfield && *subfield) { int addition = atoi(subfield); GET_QUESTPOINTS(c) += addition; } snprintf(str, slen, "%d", GET_QUESTPOINTS(c)); } else if (!str_cmp(field, "quest")) { if (!IS_NPC(c) && (GET_QUEST(c) != NOTHING) && (real_quest(GET_QUEST(c)) != NOTHING)) snprintf(str, slen, "%d", GET_QUEST(c)); else strcpy(str, "0"); } else if (!str_cmp(field, "questdone")) { if (!IS_NPC(c) && subfield && *subfield) { int q_num = atoi(subfield); if (is_complete(c, q_num)) strcpy(str, "1"); else strcpy(str, "0"); } else strcpy(str, "0"); } break; case 'r': if (!str_cmp(field, "race")) { if (subfield && *subfield) { int ra = get_race_by_name(subfield); if (ra != -1) { GET_RACE(c) = ra; snprintf(str, slen, "1"); } else { snprintf(str, slen, "0"); } } else sprinttype(GET_RACE(c), pc_race_types, str, slen); } else if (!str_cmp(field, "room")) { /* in NOWHERE, return the void */ /* see note in dg_scripts.h */

I've never done code blocks on here. Hope it looks Ok and is easier to read. Seems that way in the preview window.

Interesting I copy your exact code into my compiler and it compiles fine. It looks fine. Did you include your race file?
