Copy Stream

[lucassunalt]

Is it possible to copy a stream such that the new stream can be interacted with as if it were an initial state? Code:

stream.write(>start {"formatid":"gen9randombattle"});
stream.write(>player p1 {"name":"Player 1"});
stream.write(>player p2 {"name":"Player 2"});

function randomGame(stream, depth){
const streams = PS.getPlayerStreams(stream);

omniscient = streams.omniscient;
spectator = streams.spectator;
p1 = streams.p1;
p2 = streams.p2;
p3 = streams.p3;
p4 = streams.p4;

const logging = (depth == 0);
const p1bot = new RandomBattlePlayer(p1, logging);
const p2bot = new RandomBattlePlayer(p2, logging);

void p1bot.start();
void p2bot.start();

void (async () => {
    for await (const chunk of omniscient) {
        var lastmessage = chunk.split('|');
        if (lastmessage.slice(-2, -1) == 'win' && logging){
            console.log(lastmessage.slice(-2, -1) + ' ' + lastmessage.slice(-1));
            return lastmessage.slice(-1);
        }
    }
})();

}

// Somehow copy stream 2 so that the battle states are the same, but different RNG seed.

winner = randomGame(stream, 0);
winner2 = randomGame(stream2, 0);
