Racial Data[edit]
I shall use assembly language syntax instead of C, as that's what my disassembler delivers.
The race_data_vector is an array of pointers to instances of an object we will hereby call race_type. The instances are, of course, generated from the [CREATURE] entries in the raw files.
race_type appears to contain several custom sub-objects as well as standard ones such as strings.
This structure merely groups two strings, a singular noun and a plural noun.
00000000 s_p struc ; (sizeof=0x38) 00000000 singular string ? 0000001C plural string ? 00000038 s_p ends
This structure groups three strings, a singular noun and a plural noun and a noun I call "corpse" as it is used when displaying info about a corpse. (It is probably used in other ways as well.)
00000000 s_p_c struc ; (sizeof=0x54) 00000000 singular string ? 0000001C plural string ? 00000038 corpse_prefix? string ? 00000054 s_p_c ends
This structure groups color information. It is not obvious whether the original code has a color substructure, but I decided to make one anyway. I have not tested whether the red, green, blue fields are in the proper order. Edit: this appears to be foreground color, background color, and the bold flag, just like the raws define it.
00000000 color_type struc ; (sizeof=0x6) 00000000 red? dw ? 00000002 green? dw ? 00000004 blue? dw ? 00000006 color_type ends
This structure groups certain temperature-related information.
00000000 temperature_table struc ; (sizeof=0xE) 00000000 spec_heat dw ? 00000002 heatdam_point dw ? 00000004 colddam_point dw ? 00000006 ignite_point dw ? 00000008 melting_point dw ? 0000000A boiling_point dw ? 0000000C fixed_temp dw ? 0000000E temperature_table ends
Finally the (huge) race_type object. Note the lack of a vtable, implying that race_type is probably not subclassed.
00000000 race_type struc ; (sizeof=0x20A0) 00000000 token string ? ; TOAD, COW, EQUIPMENT_WAGON 0000001C name s_p_c ? ; cow:cows:bovine 00000070 chunk s_p ? ; remains:remains 00000070 ; chunk:chunks 000000A8 extract string ?

Most everything that the raws can set on a creature has been found. The arrays near the end are not set by the raws, and are currently unknown.
race_type.flags_ptr needs further explanation. The object does not contain the associated flags; instead it has a pointer to a bitvector of flags. To test a flag in the bitvector, divide the flag number by 8 (number of bits in a byte). The quotient is the byte to test, the remainder is the number of bits to shift the mask. Flag 0x43, for example, is tested by (BYTE *)(race.flags_ptr)[8] & (1 << 3) .

- A thought: If I was designing this structure, all of these seldom-used fields would be kept off in a vector of strings and parsed when needed. I mean,
remains_coloris used once in the entire game, and it's for a creature that (I think) can't even appear!demon_sphere_vector?cheese_liquid_density? Now, really.
