# Follow (of `Motion`)

class `Follow`

  Defined in Follow.sc.

  A motion class that is used to make an Actor move so it stays within a certain distance of another (possibly moving) object.

  Example usage:

      ; Make the dog follow the ego at a distance of 20
      (aDog setMotion: Follow gEgo 20)

  Note that this class doesn’t intelligently move the Actor around polygon obstacles. For that, use `PFollow`.
