I don't think you can specify position by caste (you can specify by creature class, but I'm fairly sure creature classes are handled at the creature level, not the caste level).
Oh, allright, I'll try to look into that when I get the time (school's taking up quite some time, those teachers are even worse than the clowns!)
The wiki didn't say anything about that though, only df2010 mention of creature class is this, so maybe it's time to update the wiki?
Creature class. Can be anything, but only existing use is GENERAL_POISON. Appears to only be used for Syndromes. Supposedly can also be used for entity positions.
A queen is just a female monarch; if this race is truly insectoid, there shouldn't be any "kings".
"Kings" would be the Drones, they are the only male members of this species, the queens can't produce offspring without them. Or can they?
So right now I have something like this (note: all numbers are subject to change, these are excerpts from an unfinished creature's RAWs)
[CASTE:WORKER]
[FEMALE]
[LITTERSIZE:0:0]
[BABY:24]
[CHILD:34]
[POP_RATIO:90]
[CASTE:QUEEN]
[FEMALE]
[LITTERSIZE:100:200]
[BODY_SIZE:0:0:6000]
[BODY_SIZE:0:30:42000]
[BODY_SIZE:0:60:120000]
[BABY:30]
[CHILD:60]
[POP_RATIO:1]
[POPULATION_NUMBER:0:1]
[CASTE:DRONE]
[MALE]
[POP_RATIO:9]
[BODY_SIZE:0:24:14000]
[CHILD:24]
this'd mean that one percent of the total population will be of the Queen Caste right?And there will be only one queen on a map at the same time (I'm guessing this mean an Embark location map)? Would this work or would a code like this just mean that the Drones would waste their time trying to impregnate the infertile Workers that make up 90 percent of the populace?
Additional questions: -Are the offspring of a certain caste spread over multiple castes or will they all become part of their mother/father's caste? (So I don't just end up with 200 queens etc.)
-Is it possible for creatures to dig without using picks? eg: using body parts to dig, like insects do. (I'd like to make this race player civ-controllable, may have to lower birth rates though...)
-For [BABY:X] and [CHILD:X] are the X's counted as days or as years? If they are counted as years, is it possible to express days as [BABY:0:24]? (insects mature quickly, but never get older than 4~6 years)
Oh, and the insects have quite a hard exo-skeleton and never get tired or afraid. Except for the queen, who is the only one with wings and will flee when wounded in battle (but I'm thinking of just giving her a ranged attack instead of wings, or a toxin to cause leg paralysis/instant brain rot, or all of them), so if anything tries to kill the queen they'll first have to fight their way through a nest full of fanatic, armored, vicious, giant ants with claws. Who. Will. Never. Stop. Coming, especially if the queen has just given birth, after which they have to fight a bug of enormous proportions...
So I don't think the queens really risk getting killed, though old age might finish them off eventually (even with longer-than usual life spans)
