I created a turtle and added "pen-down" to see how the turtle traveled and once the turtle stopped, it was hard to spot its final location with all the traces. I need help removing traces left by turtles in "pen-down" mode in order to see the turtles final location. I'd like to do this by pressing a button on the interface that removes the traces, however, I don't know the exact code to be able to do that.
Any help would be appreciated, thanks.
Sounds like you want clear-drawing, http://ccl.northwestern.edu/netlogo/docs/dictionary.html#clear-drawing.
