Error in bulletClass of the Phaser.Weapon

[ArmTwo]

Hi,

In the documentation of the Weapon, the property bulletClass speak the follow:

bulletClass : Object => "The Class of the bullets that are launched by this Weapon. Defaults Phaser.Bullet, but can be overridden before calling createBullets and set to your own class type."

that could be written:

class MyWeapon extens Phaser.Weapon {
  contructor(){
    super();
    
    this.bulletClass = MyBulletClass; /*error here*/
    this.createBullets(30, imgSprite);
  }
}

the problem is that que the method bulletClass executes internally the code:

https://github.com/photonstorm/phaser/blob/v2.6.2/src/plugins/weapon/WeaponPlugin.js#L1130

this.bullets.classType = this._bulletClass;

But this.bullets still not was instantiate(null), so throws the error "can not read property 'classType' of undefined".

If i comments the line, everything works.

Would this line really necessary?

I'm using Phaser 2.6.2.

It's necessary if the bullet pool already exists, but it creates this problem if it doesn't. A workaround is

this._bulletClass = MyBulletClass;
this.createBullets(30, imgSprite);

Hi @samme, the problem is that the typescript accuses error, saying that the property not exists. But works anyway.

could have a conditional for check if this.bullets is null. i looked the Phaser CE and it have this:

//prevent crash if weapon's bullets have not yet been initialized
if (this.bullets) {
    this.bullets.classType = this._bulletClass;
}
