Overview

This is a game playing a match using an aircraft operating with a JavaScript program called sourcer.

Rule

The goal of a game is for attack the opponent's shield to 0, winning the game.

Attack

Laser: The laser flies straight. The laser ammo is unlimited.
Missile: The missile can be operating with a JavaScript program like sourcer. The missile ammo is 20. Missiles can be shot down with a laser.

Status

Shield: Initial value 100. The shield will decrease when attacked. When the shield of your sourcer runs out, you lose.
Temperature: Initial value 0. It will rise when you attack or get damaged. When the temperature exceeds 100, the shield gradually decreases. The temperature gradually decreases.
Fuel: Initial value 100. Fuel is reduced as you move. When the fuel runs out, it can not move.
Missile ammo: Initial value 20.

Other

There is a ground at a position where the altitude is 0, Touching the ground reduces shielding.
Sourcer is pulled by gravity and gradually attracted to the ground unless it moves. Lasers and missiles are not affected by gravity.

Program

You can operate with the controller of the argument.

var bot = function(controller) {
  if (controller.altitude() < 100) {
    // ascent when the altitude goes down.
    controller.ascent();
  }
  controller.ahead();
};
return bot;

Entry commands by the controller => Command execution => Entry command => Execution => ... will be repeated.

Behavior that can be done with the controller.

Move: Ahead, back, ascent, descent.
Radar: Scanning enemies, Scanning flying attacks.
Attack: Laser launch, missile launch.
Check status: Check shield, temperature, fuel, missile ammo.

If you use radar, the time to the next action will be longer.

Only one attack is accepted in a single action.

The missile program is specified as an argument when fire command.

var missile = function(controller) {
  if(controller.scanEnemy(90, 180)) {
    controller.turnLeft();
  } else {
    controller.turnRight();
  }
  controller.speedUp();
};
var bot = function(controller) {
  if (controller.altitude() < 100) {
    controller.ascent();
  }
  if (controller.frame() % 16 === 0) {
    controller.fireMissile(missile);
  }
};
return bot;

	return function(controller) {
		if (controller.altitude() < 100) {
	    controller.ascent();
	    return;
	  }
	};

var missile = function(controller) {
  if(controller.scanEnemy(90, 180)) {
    controller.turnLeft();
  } else {
    controller.turnRight();
  }
  controller.speedUp();
};

var bot = function(controller) {
  // ...
  controller.fireMissile(missile);
  // ...
};
return bot;

fireLaser(direction, power)

Fire the laser.

{number} direction: Direction of the radar. The direction of Sourcer is 0, the upward direction is a positive value, the downward direction is a negative value.
{number} power: Power to launch.

fireMissile(source)

Fire the missile.

{function} source: Function for controlling missiles.

log(message)

Show the message to the screen.

{string} message: Message to output

You can also use console.log()

scanDebug(direction, angle, renge)

Show the circular sector for the specified direction, range and distance.
