Phaser.Group#iterate: Cannot set property '0' of undefined

[tasos-ch]

Example

var group = new Phaser.Group();
group.iterate('name', 'test', Phaser.Group.RETURN_NONE, function(item) {})

The above code fails with the message:

Uncaught TypeError: Cannot set property '0' of undefined

The Problem

Line 1468 of the Phaser.Group file is causing the problem. This line reads:

args[0] = this.children[i];

The problem is that the args argument is not initialized anywhere inside the iterate method before that call.

Possible Solutions

For me it would be enough a relevant description of the args parameter to be added in the documentation where it would be mentioned that when a callback is set, then a value for the args parameter should be set as well.

This is now fixed in dev.
