robocode-js

LiveScript (Javascript) implementation of Robocode. Original from http://gumuz.nl/projects/robojs/

• I created this project for students in NCCUCS Software Engineering Course (2014) to learn teamwork in git/github. For more information, please refer to http://nccucs-se.github.io/

• The final idea is to donate this project to g0v, for begineers of open source developers to learn git/github in a fun way.

• The project is now lack of UI, to fight your own robots, you may need to edit the HTML pages to add your robot scripts to it.

• Demo: http://youchenlee.github.io/robocode-js/

• Report issues to https://github.com/youchenlee/robocode-js/issues

Creating a robot is even simpler

importScripts('base-robot.js')

class TestRobot1 extends BaseRobot
  onIdle: ->
    @turn_turret_left 30
    @move_forwards 100
      if Math.random! > 0.5
        @turn_right 30
      else
        @turn_left 30

  onWallCollide: ->
    @move_opposide 10
    @turn_left 90

  onEnemySpot: ->
    @shoot!

  onHit: ->
    for d from 20 to 30
      @move_backwards d
      @turn_right d

bot = new TestRobot1("My test robot")

Advanced:

  onEnemySpot: ->
    @my-var = @enemy-spot # remember it
    @shoot!

TODO: need more bot actions and callback events

Robot HOWTO

Available info:

• Self info

  • @me.id
  • @me.x
  • @me.y
  • @me.hp
  • @me.angle - Your current angle (tank angle + turret angle)
  • @me.tank_angle
  • @me.turret_angle

• Enemy info

  • @enemy-spot[N].id
  • @enemy-spot[N].hp
  • @enemy-spot[N].angle - The angle (direction) to the enemy

Sequential Actions:

• @turn_left (angle)
• @turn_right (angle)
• @move_forwards (distance)
• @move_backwards (distance)
• @move_opposide (distance) - This action can only be used in OnWallCollide()

Parallel Actions:

• @turn_turret_left (angle)
• @turn_turret_right (angle)
• @shoot()
• @yell(message)

Events:

• OnIdle() - Triggered when idle (MUST implement)
• OnWallCollide() - When the tank collide the wall
• OnHit() - When hit by a bullet
• OnEnemySpot() - When your turret is directly face to an enemy (there seems no reason not to fire!)

Build from LiveScript

• To compile from LiveScript, first, install nodejs from http://nodejs.org/
• Second, make sure you got npm and run command exetable on your console. (If you are on MS Windows, make sure the PATH environment variable is setting correct to run npm and node)
• If you have make command, i.e. on Linux or Mac OSX, just go to the repository root directory and type make, everything will be done.
• If you do not have make command, run the following command manually. (haven't test on MS Windows.)
  • npm install
  • node_modules/.bin/lsc -c *.ls
  • node_modules/.bin/lsc -c -b log.ls
  • node_modules/.bin/lsc -c robot/*.ls
• Done. Use your browser to open index.html file.

Run directly without compiling anything

• switch to gh-pages branch, you will got everything to run this program.

  git checkout gh-pages

Note

• google-chrome is not allow to run a web worker of a local javascript file. Please use the --allow-file-access-from-files option to start chrome. If you run this project on a web server, this won't be a problem.

Licensing

• The first version of my LiveScript codes are converted from CoffeeScript, which is the work from Guyon at Gumuz. Guyon has agreed to release this project in a opensource license, but we havn't decide the license yet. It will be likely to be MIT. I'll update later.

• All the arts in this project are under the Eclipse Public License (EPL).
