Le Twitch 4 Report post Posted July 26, 2014 Math.floor(Math.random() * 2); VS game.rnd.intergerInRange(0, 1); how does "game.rnd" work compared to "Math.random"? which one is preferred? Quote Share this post Link to post Share on other sites
lewster32 616 Report post Posted July 26, 2014 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) 1 Yehuda Katz reacted to this Quote Share this post Link to post Share on other sites

lewster32 616 Report post Posted July 26, 2014 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.

hoskope 2 Report post Posted January 24, 2016 Yeah, this is great. I created my own random and find out later that it's inside framework Quote Share this post Link to post Share on other sites
