✅ random current value?
Hello, I'm using a naïve Random generator, and I'd want to display the current seed used, in the hope to replicate the current state for some later replay.
How can I achieve that, apart from having a second Random seeding its
.Next() int to the actual Random?19 Replies

Hmm, I'll have a thought about that, thanks.
Setting the seed explicitly alos has uses. And yep, you can get that seed from another Random
Yeah, basically, what I told in the opening: getting a "seeding seed" that I borrow (and save) to be used as actual seed.
That's not that much inconvenient, but isn't it possible to get the
.Current value of a random?(although use
Random.Shared.Next() to avoid newing up a new instance)
Well, the internal state is an implementaiton detail, and in fact the amount of state which is stored got changed a few .NET versions agoTo be fair, I already have the seeding in place:
Random rand = seed is null ? new() : new(seed.Value);, just in that "non-seeded" case, I'd want to borrow the value.
It'll be a random seed buffer then.
Yeah, I've seen that...

That's totally what I call a random buffer, not in the randomness sense but in buffer name use. 😄
I'd wish I could just
.Current() to get the current value tho.Unknown User•3mo ago

Yes, but that's a hassle on my end!

I love when someone else has the responsibility for my storage.
There is no problem though, thanks for the help. 🙂

If
Random.Current() was a thing, I'd not have to store the picked value on my side. 🙂Unknown User•3mo ago

Yea, the value source doesn't really matter, I may use any source I'd wish as a source for
.Next.
LPlateau[i] = new(this, new(i_x, i_y), (rand.Next(iMax - i) < mines - minées) && minées == minées++); //Référencement de la case
It's actually used here (and only there), at lPlateau initialization, in a foreach loop.
I know this is a bit hard to read, but there's the lowest I could get to not having rands everywhere on multiple lines.
So, when no seed is set as a base, I'll generate one, and use it as a (spoofed) set down the line. 👍
It works, thanks.int graine = seed ?? Random.Shared.Next();Nice catch.
