First set of questions no ideaTwo questions:
One: how do I get an actor that's living with the player, regardless of relationship? For that matter, how would I get the number of people living there?
Ok, that was two questions, but this is still my second question: In a scene's WHAT condition, how do I specify no activity, non-exclusively. For example, the scene should have a chance to fire when the player is performing specific related activities or isn't doing anything but passing time.
Second set you'd have to have a unique trigger and the What condition set to none.
As an example of a script that does this look up NPC_discovers_pregnancy.lpscene. You'll be able to find it in /content/modules/vin_Pregnancy/Scenes
