Ladies and gentlemen, Maybe I am doing something wrong, but it seems to me that the function chanceRoll() is missing as of the latest update (it does not show up among the available functions under math when I look at "Game" in the browser console). It is clearly referenced in the documentation (http://phaser.io/docs/2.4.2/Phaser.Math.html#chanceRoll) and from what I can tell it is not deprecated. Am I missing something? // Majtorp
