Math.random vs game.rnd

Recommended Posts

game.rnd is an instance of Phaser.RandomDataGenerator which as well as having a lot of nice convenience methods, is also a seeded pseudo-random number generator, meaning you can get repeatable results from it. See this example: http://examples.phaser.io/_site/view_full.html?d=misc&f=repeatable+random+numbers.js&t=repeatable%20random%20numbers (check the developer console to see the output)

It's great if you want to create 'random' levels which always play out the same, or use 'random' events in multiplayer games and ensure the same things happen on each client. Minecraft's world generation is driven by a seeded PRNG as well, which is why the same level seed will always produce the same virtually infinite world.
