PRNG

Generic typessource

PRNG (short for Pseudo-Random-Number-Generator) holds 10 128bit wide buffers of memory that are mutated on every generation of a random number. The game uses specific buffers for specific scenarios, for example the third buffer is used every time particles are spawned to determine a random velocity. The used buffer is determined by PRNG_CLASS. If you want to make a mod that does not affect level generation but still uses the prng then you want to stay away from specific buffers. If you don't care what part of the game you affect just use prng.random.
