You can have her walk and then fall.
You would code the walk first
@YOU walks to spot 0.853 89 180 in zone 1
I would add a time, ex. 1 second
@YOU walks to spot 0.853 89 180 in zone 1 in 1 THEN YOU is fall
If you’re not happy with her spotting after she falls, put
THEN YOU spot xxx AND YOU is fall
Make sense?
