Random Number Generator

Description

The cRandom library replaces and extends the standard random number generator. A 64-bit number is used as seed, which ensures sufficient randomness of the number. The limited randomness of the standard 32-bit generator can be observed, for example, when generating terrain - it will appear as waves in the terrain. You can either use the global variable Rand and the functions belonging to it, or create another local generator cRandom. The following functions refer to the global Rand generator. It is recommended to use the RandInitSeed() function when starting the program to ensure the generator is non-repeating.
