what context to pass for weapon.fire function

[ghclark2]

Hi,

I am really confused why I am getting errors with this code from the weapon plugin:
 

  create: function() {
    //load current level
    this.loadLevel();

    this.weapon = this.game.add.weapon(-1, 'explode');
    this.weapon.fireFrom.setTo(300,300, 1, 1);

    this.weapon.bulletKillType = Phaser.Weapon.KILL_CAMERA_BOUNDS;
    this.weapon.bulletGravity.y = -1000;

    this.input.keyboard.addKey(Phaser.KeyCode.SPACEBAR)
        .onDown.add(this.weapon.fire, this);

The error is:

phaser.js:100951 Uncaught TypeError: Cannot read property 'width' of undefined
    at Object.Phaser.Weapon.fire (phaser.js:100951)

It seems to be an issue with the context, but I have tried this.weapon, this.state, this.game all to no avail. Annoyingly if I run ZPlat.GameState.weapon.fire() from the console it shoots fine.

If anyone can see what I'm doing wrong I'd be very grateful.

Thanks, Gordon

add(this.weapon.fire, this.weapon)

should be the right context, but probably that's passing the signal's arguments into fire, where they don't match. So try it just as

add(function () { this.weapon.fire(); }, this)

That's great - many thanks!
