You can get the same result by hashing seed+level_id+some_counter, you don't really need a prng.

  The _advance function in this prng is also way too weak, purely linear with a tiny bit of output mixing. Replacing self.state with the (64-bit) result of the xorshifts would help a lot.

    Are you claiming that PCG is a bad pseudorandom number generator? If so, you are mistaken

      Yes, I predict it will fail most of the DieHard tests.

        I like your murmur work, but you're getting it wrong today
        • aappleby 5y ago
          Getting it wrong is part of the job.
          • 37ef_ced3 5y ago
            Agreed. No one should hold it against you But we have to be careful about claiming that a generator is unreliable. PRNGs are very susceptible to rumor and uncertainty and doubt, because almost nobody understands them
