the list can be expanded only with its own variable eg var i in the program code.

my problem was a wrong port number, i used port=3333 instead of port=33333.
Now my project works fine.
But i cant understand why in my project appear little variable for my e-puck than the challenge ?
So, in my projetc i can see "speed.left" but in challenge there are more variable for example "wheel.left_speed"
How could i add a new variable in that list ??

Aseba playground used asebaswitch?. Is it into the installation Directory from aseba studio?

the Aseba playground file has been changed?

look them in the file at the end unifr.playground
is <e-puck x="15" y="30" port="33334"/> or <e-puck x="15" y="30" />
you can edit the port there.

Im a newbie, and i have some problems to simulate only one e-puck.
I clicked on Simulation > Aseba Playground and load unifr.palyground.
But i open Aseba studio and "Aseba target selection" dont let me enter on studio.
I selected network(TCP) and localhost, port 3333 and click on connect but dont go.

Thank´s and excuse me i dont write in english very well.
