About
This is a proof-of-concept, clone of Robocode. Built using Javascript & CoffeeScript using HTML5 Canvas and Web workers.

How does it work?
Every Robot runs in it's own Web Worker thread. A robot sub-classes a base robot which handles the worker/event-loop communication and event propagation. The new robot just has to implement behaviour using call-backs, reacting on possible events:
importScripts('base-robot.js');
ScanBot = BaseRobot;
ScanBot.run = function() {
var robot = this;
robot.shoot();
robot.turn_turret_right(45);
robot.move_forward(Math.random()*400, {
DONE: function() {
robot.shoot();
robot.turn_right(Math.random()*90, {
DONE: function() {
robot.shoot();
robot._run();
}
});
},
ENEMY_COLLIDE: function() {
robot.shoot();
robot.move_backward(100, {
DONE: function() {
robot._run();
},
WALL_COLLIDE: function() {
robot._run();
}
});
},
WALL_COLLIDE: function() {
robot.turn_left(180, {
DONE: function() {
robot.shoot();
robot._run();
}
});
}
});
}
CoffeeScript
A preliminary CoffeeScript port is also included, making the whole base-bot extending and callback handling a bit cleaner:
importScripts('base-robot.js')
class TestRobot1 extends BaseRobot
run: () ->
@move_forwards 10, =>
@move_backwards 10
@turn_left 45, =>
@_run()
tr = new TestRobot1("My first test robot")
