Racial Data

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)

000020A0 race_type ends

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_color is 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.
