Tracking Entities
During a playback
or a recording, you can select specific Entities to track within the
simulation. This can be useful for checking that Entities are behaving as
expected or intended. Displaying Entity Trails makes them even more
distinctive. You can set the length (and information conveyed by) of Entity
Trails in
(see
Setting the length of
Entity Trails).
The number of tracked Entities at any point is displayed in the Output Bar.
To select Entities to track:
-
Click
or select
.
-
When Entities that you want to track enter the simulation, click
or select
.
-
Select Entities by holding down the <Ctrl> key and
dragging the cursor around them. You may need to pan or zoom within the display
to isolate certain Entities.
Each selected Entity is now marked by yellow cross-hairs (to de-select Entities, hold down the <Shift> key and draw around them to remove their cross hairs). The number of tracked Entities is also displayed in the Output Bar.
- If you also want to
display the ‘trails’ of the Entities you are tracking, click
or select
. This displays a red trail behind each
of the Entities, which makes their pattern of progress easier to follow. If you
want to change the length of Entity trails, see
Setting the length of
Entity Trails.
- If you also want to
display the ‘trails’ of the Entities you are tracking, click
- Repeat step 3 for any other Entities you want to track.
-
Click
or select
to continue with the simulation.
To track Entities by filter:
- 1. Click the 'Track Entities by Filter' icon.
- Create a filter as described in Entering advanced filters .
-
Click
OK.
The software will automatically track any Entities captured by your filters.
- If you want to exclude Entities captured by your filter, check the box labelled 'Stop tracking entities which satisfy this filter'.
