I'm looking to check the x value of all children of an emitter and kill it if x > 200. Here's my immediate non-phaser method solution (this is in the update loop) for (var i = 0, j = windEmitter.children.length; i < j; i++) { var s = windEmitter.children[i]; if (s.x > 200) { s.kill(); }}Seems like there's got to be a more efficient way to use a Phaser.Group method ( like checkAll() or callAll() ) but I can't figure out how to format them and still include my conditional. Thoughts?
