path problem

Hi,
I'm new to breve so my question is very simple.
I'm trying to make simulation where an agent walks on the floor and where 
I can see its trace (I mean the path he walked through). Is it possible? 
How can I make it? The only way I found is to make it walk on the objects 
(the 
floor is made up of objects)and to change the objects color when it (the 
agent) reaches it. Is there any other solution?

Thanks,
Agnieszka
