Laby

Laby is an easy to use IDE to program a rock-carrying ant-robot trapped in a maze. Usually there is a door the robot wants to reach, but before that, it needs to sort out several traps on its way. Help the robot by writing a program that guides it out of the maze. Even if you have not programmed before this is a great game to start. Help the robot and learn to program several languages at the same time: Ruby, Pascal, Perl, OCaml, and Java. They are mini-versions of the original languages, but you will still learn the fundamental of loops, conditionals and functions and what is better you will have fun while doing that.

Enjoy!

Example

Here is a code example and everything you need for Ruby, let us know if you want this example in the other languages too. It is the solution of the level 2b. We are planning adding a lot of levels and some AI for complex path finding.

require "./robot"

# Level 2a
#   ....+....1....
# 1 +-------------
# . |a           d
# . +-------------
# a = Ant Robot
# d = Door
#
# Help:
#
# Constants:
#   Void - empty space
#   Rock - there is a Rock
#   Web - there is a Web
#   (more...) later :)
#
# Built-in functions:
#   look() - look forward and returns and object name
#
# Basic Movement:
#   forward
#   left
#   right
#   escape - open door
#
# Rocks:
#   take - take rock in front
#   drop - drop rock to front
#
# Loops:
#   while look() == Void
#     ...
#   end
#
# Conditionals:
#   if look() == Web
#      ...
#   else
#      ...
#   end
#
# Functions:
#   def f
#     ...
#   end

# Example Code to solve Level 2b:
class Ant < Robot
  def ant
    while look() == Void
      forward
    end
    escape
  end
end
