Display direction

[Jayshree Sarma]

Hi,

In my application the agents have a notion of direction in which they
are moving.  They can move only in four directions (NEWS). The agents
change their heading direction based on some actions.  Right now the
display only shows the dots moving around.

What I would like to do is display the direction they are moving by
adding a line to the dots displayed on the zoomraster. The line
indicates the direction in which the agent is moving (or headed).
This makes it more visually appealing, at least we can see which way
the agent is headed.  But I am not sure if this can be done. I looked
at the documentation for line and not sure if I can use it. Any pointers
will be greatly appreciated.


Thanks,

Jayshree Sarma
