Detailed Description

A random number generator.

Each objects that needs a random number uses its own number random generator. They are all seeded with number provided by the server. This guarantees that in a network game all 'random' values are actually identical among all machines. The formula used is x(n+1)=(a*x(n)+c) % m, but m is assumed to be 2^32, so the modulo operation can be skipped (for 4 byte integers).
