Particles.Arcade.Emitter#filter()

filter(predicate, checkExists) → {Phaser.ArraySet}

Find children matching a certain predicate.

For example:

var healthyList = Group.filter(function(child, index, children) {
    return child.health > 10 ? true : false;
}, true);
healthyList.callAll('attack');

Note: Currently this will skip any children which are Groups themselves.

Parameters

Name	Type	Argument	Default	Description
`predicate`	function			The function that each child will be evaluated against. Each child of the group will be passed to it as its first parameter, the index as the second, and the entire child array as the third
`checkExists`	boolean	<optional>	false	If true, only existing can be selected; otherwise all children can be selected and will be passed to the predicate.

Returns

Phaser.ArraySet -

Returns an array list containing all the children that the predicate returned true for
