===================================================

Getting a npc companion to lie down is actually easy if you can setup even the most basic dialogue. What you do is just make a couple of topics name them what you want such as "sleep" and "wakeup".

In the results box in the dialogue editor in the sleep topic type in "PlayGroup DeathknockOut" (there are other animations this one was just the most suitable) (this does not kill the npc it just plays the animation and they lie there blinking and alive as if resting) after that It's just a matter of dropping the bedroll on top of them (the game automatically raises them on top of the bedroll (you could put the bedroll down first, but it would take a while hoping the npc falls on it the way you want so it's easier to drop the bedroll after.

To get them to wakeup in the "wakeup" topic you made type in "Playgroup Idle" and they'll standup. These are just commands to play animations that came with the game. (I don't know if I'm the first to implement this particular animation for this purpose) But, this has been done before with other mods to get npcs to dance ect. You can experiment with different animations and multiple animations to get some interesting results.
