Activity Checklist

  • To make a wheel appear to move, we want to rotate it by a small amount and move it by a small amount when we receive a movement broadcast.

    when I receive
    change x by
    move speed
    *
    -1
    turn
    15
    degrees
    when I receive
    change x by
    move speed
    turn
    15
    degrees
  • If you wanted, you could replace the values with variables like move speed, so you could control the speed in all directions from one place.

(Notice how we have to multiply moveSpeed by -1 to get the negative value?)
