Tracking Entities
During a playback or a recording, specific Entities can be 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. The length (and information thereby conveyed) of Entity Trails can be set in Tools > Options (see Setting the length of Entity Trails).
To select Entities to track:
- Click or select Playback > Play.
- When Entities that you want to track enter the simulation, click or select Playback > Pause.
- Select Entities by holding down the <Ctrl> key and dragging the cursor around them. Pan or zoom within the display to isolate required Entities.
- To display the trails
of the tracked Entities, click
or select Display > Tracked
Entity Trails. This displays a coloured trail behind each of the Entities,
which makes their pattern of progress easier to follow. Trail colour
corresponds to Entity Type.
- To change the length of Entity trails, see Setting the length of Entity Trails.
- Repeat step 3 for any other Entities that need to be tracked.
- Click or select Playback > Play to continue with the simulation.
- The number of tracked Entities is displayed in the Output Bar.
Tracking Entities by Filter
Specific Entities can be tracked by creating a tracking filter. To track Entities by filter:
- Click the Track Entities by Filter icon.
- Create a filter as described in Entering Advanced Filters.
- Click OK.
- To cancel the Entity tracking filter, tick the box labelled Stop tracking entities which satisfy this filter.
