Hey guys,   I'm back in the saddle working on my game but since updating my existing game to Phaser 2, I'm scratching my head on a few things.   The first thing is that my grouped sprites are not registering the touching.down as they hit the layer. What am I doing wrong here? JumperBot.prototype = Object.create(Phaser.Group.prototype);JumperBot.prototype.constructor = JumperBot;JumperBot.prototype.update = function() { this.forEach(updateJumperBots, this, true);}// Update for each JumperBotfunct
