I'm currently running experiments with evolved robot controllers and
I'm trying to see the robot's trails during multiple attempts at
navigating towards a light source. At the moment this involves
randomizing the robot's initial state, placing it in the environment
and letting it run, and repeating the process several times with
different randomizations. The problem is that whenever I reset the
position of the robot, the trail vanishes, and the movement from the
final position of one trial to the initial position of the next trial
becomes the first segment of a new trial.
Is there a way to have trails persist in the environment between
resets? I've tried to piece together how the code is running, and it
seems like I would need to store every generated trail separately, so
they can be drawn independent of the robot's position. I have no
problem doing that, but is there a better way?
