Extend Weapon Plugin (TypeScript)

Recommended Posts


I'm trying to make separate weapon classes in an Asteroids-type game, for example a Missile.ts, Laser.ts, etc.

What I have so far is this (Missile.ts):

module Spaceroni {

    export class Missile extends Phaser.Weapon {

        constructor(game: Phaser.Game) {

            super(game, game.plugins);
            this.bulletKillType = Phaser.Weapon.KILL_LIFESPAN;
            this.bulletSpeed = 1500;
            this.fireRate = 20;




In my Player.ts I have

weapon: Spaceroni.Missile;

up top and I'm adding a weapon in its constructor with

this.weapon = game.add.weapon(30, 'missile');

This isn't working (bulletSpeed and fireRate aren't changing), I think because game.add.weapon() creates a new weapon instance, separate from my Missile class. I would like to avoid putting all of this Missile-specific code directly into the Player class since I want to be able to change the weapon based on power-ups, as well as add the Missile weapon to enemies.

Any ideas on how to properly extend the weapon plugin?

Thanks in advance!

Hi, you need a helper similar to game.add.weapon:

Phaser.GameObjectFactory.prototype.missile = function (quantity, key, frame, group) {
  var missile =;

  missile.createBullets(quantity, key, frame, group);

  return missile;

// …

this.weapon = game.add.missile(30, 'missile');
