Patient takes an elevator to a floor with a negative Z

Hi,

Open the attached model Patient + Elevator v1.fsm.

The patient takes the elevator down to the floor spot:

Open the attached model Patient + Elevator v2.fsm.

The patient walks towards the elevator, but the elevator does not go up. The patient walks down to the elevator.

Here is the difference between these 2 models:

• version 1: the floors are at z = 5m and z = 0m
• version 2: the floors are at z = 0m and z = -5m

Should there be a fix ?

Or is it forbidden to use elevators with floors at negative Z locations ?

In the properties of an A* grid, typing a negative value in the Z position field is not allowed, the value is set back to 0:

However, if you set the 3D view Grid Z field at a negative value you can actually create an A* grid at a negative Z location:

So having an A* grid at a negative Z seems like "half forbidden / half allowed".

There seem to be some assumptions in the code that A* grids would never be at a negative Z height. I'll add this to the dev list to discuss allowing negative z heights. For now though, I would stick to positive Z heights for the grids.

Thanks Matthew for the new update in 23.0:

Allowed A* grids Z height to be negative.
