I am stuck with challenge XX.
Perhaps the code i wrote broke the template which was given at the beginning. I can't reset the challenge, it always shows me the code I wrote and not the initial template
Generally speaking RoboMind remembers the last solution.You can use the "undo" button (open the control on the lower left of the script window by pushing the cross button, then push the "half-circel-to-the-left" button in the margin. See picture below) to reverse your changes, but this only works in one session.
Between sessions the changes are not remembered. The last solution (the last time you pushed the play button) is remembered though.
When the script window has the focus, Ctrl+Z (undo) and CTRL+Y (redo) will also work.
