stop a moving agent

[Arend Ligtenberg]

Dear all,

I would like to halt an individual moving agent heading on a network to its destination for a while, triggered by a random event.  I implemented  the moving skill  along with the standard 'goto' action which works fine. Setting the speed to 0.0 in a reflex doesn't work. 

So, is there a way to stop a moving agent for x amount of steps/tics via a reflex or other workaround? 

Any ideas are highly appreciated.

Thanks a lot!

Cheers

Dear Arend,

I think that there is a misunderstanding about the functioning of the goto action. Basically, this action has to be triggered each step (using a reflex for instance) so the agent "move" toward its destination considering how long a step represent (1s is default) and how fast it goes (speed which is 1m/s default). In fact, the location of the agent is simply changed to reflect this movement. Hence, you cannot stop an agent within a step. Whereas you are free to decide whether or not the goto action is triggered within your reflex. Meaning that you'll have to implement an if statement to prevent the goto action to be triggered for a given number of steps. In the following exemple, agent won't move for 3 step:

int stopmove <- 3;

reflex movement {

if (stopmove = 0) { do goto on:the_graph target:target speed:1.0; }

stopmove <- max(0, stopmove-1);

}

After that you'll have to implement a way to manage your stopmove condition elsewhere.

Best,

Kevin
