title: Custom Random Number Generator
body: <p>Is it possible to get an extremely fast, but reliable (Same input = same output, so I can't use time) pseudo-random number generator? I want the end result to be something like <code>float NumGen( int x, int y, int seed );</code> so that it creates a random number between 0 and 1 based on those three values. I found several random number generators, but I can't get them to work, and the random number generator that comes with Unity is far to slow to use. I have to make about 9 calls to the generator per 1 meter of terrain, so I don't really care if it's not perfectly statistically random, just that it works really quickly. Does anyone know of an algorithm that fits my needs? Thanks :)</p>
