Inside pack_tentacle_dreams\init\stories\tentacle_dreams\chars\saiko\brain\code\run there are a bunch of run.dats each of these run_states is a different part of the story if you open them up you will get some idea of where in the story, run2_state.dat is where Saiko goes to sleep.
These dat files control everything the NPCs do and editing them is pretty easy.
Each task is divided up into cases like the one shown below and when its called it will run that case.
Code:
[EVENT]
{//code goes here}
Set the current case with.
Code:
state.dyn.me.do.state2 = EVENT;
So if you were to add the [SLEEPING] code from above to one of the run files then call "state.dyn.me.do.state2 = SLEEPING;" Saiko would drop like a rock and go to sleep.
What part of the story you want her to sleep at is up to you.
