Friend or Foe 1.2 (2012-11-26)

The Friend or Foe system will allow groups of ships to work as a team independently without being setup as escorts. There is no concept of a leader or escorts/wingmen in this system. Each ship has complete autonomy and can call on help from any other team member. Each ship keeps track of who has attacked them and will ignore stray shots, ie friendly fire. Also if an attacker disappears off the scanner and later comes back the team will remember them and restart the attack run.

Ship installation HOWTO
-----------------------
For a basic installation, create a ship script that follows this template,
change the standard public variables as needed...

---- START CODE (copy all up to the END CODE block) ----
(function () {
    "use strict";

    /* Standard public variables for OXP scripts. */
    this.name = "yourshipscripthere.js";
    this.author = "Your Name";
    this.copyright = "© 2012 Your Name";
    this.license = "CC BY-NC-SA 3.0";
    this.description = "Ship script for your ship.";
    this.version = "1.0";

    /* Identifies this as a friendly to the 'Friend or Foe OXP'.
     * This is needed.
     */
    this.$fof_ship = true;

    /* Group name for your ship. Remember to set the same group name as the mother for an escort ship.
     * Optional/Not needed.
     */
    this.$fof_groupName = "yourgroupnamehere";

    /* Ship event callbacks. */

    /* The spawnedAsEscort handler is called for newly added escort ships. It does trigger on adding the ship and
     * before the shipSpawned() handlers is activated. It has the mothership as argument.
     *
     * INPUT
     *   mother - entity of the mothership.
     */
    this.spawnedAsEscort = function (mother) {
        /* No longer needed after setting up. */
        delete this.spawnedAsEscort;

        /* Register this escort as a friendly. Delay it to allow the system to do it's stuff. */
        if (worldScripts["Friend or Foe"]) {
            this.$addFriendlyTimerReference = new Timer(this, function () {
                    worldScripts["Friend or Foe"].$addFriendly(this.ship, mother);
                    delete this.$addFriendlyTimerReference;
                }, 2);
        }
        this.$isEscort = true;
    };

    /* The shipSpawned handler is called for newly added ships. It does not trigger on adding but on the first update
     * after adding. On a witchspace jump it means that first all ships are added to the system, then afterwards all
     * the shipSpawned() events are triggered.
     */
    this.shipSpawned = function () {
        /* No longer needed after setting up. */
        delete this.shipSpawned;

        if (this.$isEscort) {
            /* Already been setup as a friendly. */
            return;
        }

        /* Register this ship as a friendly. Delay it to allow the system to do it's stuff. */
        if (worldScripts["Friend or Foe"]) {
            this.$addFriendlyTimerReference = new Timer(this, function () {
                    worldScripts["Friend or Foe"].$addFriendly(this.ship);
                    delete this.$addFriendlyTimerReference;
                }, 2);
        }
    };
}).call(this);
---- END CODE ----

Place the above code in the Scripts directory of your ship OXP. In shipdata.plist add a reference to the script.
Rememeber to save the above code with a .js extension.

The player, thargoids and tharglets are ignored.

Police and Interceptors are also ignored because of the way bounties are hard-coded into the system. When Oolite v1.78 is released, it should be possible to integrate them.

== Ship script event handlers ==
This is a list of all the ship script event handlers that a ship registered with the Friend or Foe OXP will respond to. If the ship already has code for these handlers in it's ship script then they will be called afterwards.

    shipAttackedWithMissile
    shipBeingAttacked
    shipDied
    shipTargetDestroyed
