How do outcomes to events get determined?

[JackHazardous]

I've noticed that while trying to save scum (all i want is some living fucking apocalypse survivors from the fucking vault) is that if you save a day or two before the project would complete, you will always get the same outcome,anyone else with similar experiences.

Likely they save the random seed in the save file, so that you can't save scum like that.

you can still save scum, you just have to go back a month or two, all it does is make savescumming more tedious.

Actually you have to know how they use random numbers to save scum. Generating a different random event first is enough to possibly change the outcome.

I'm not sure what you mean.

I'm not sure what you mean.

A game typically doesn't generate true random numbers (a series of numbers that cannot be predicted), but a series of pseudorandom numbers that if you try hard enough you can determine where in the sequence you are, and predict what the next number will be. Every time you generate a random value, the computer simply will serve up the next number in sequence. Where it starts in the sequence is the seed, and when you get a new random number, the next value given is the new seed value.

To generate a new outcome, you must first make the game roll a different random number, thus advancing the seed to the next number, then have it try to roll for what you want to change. How you do this is your challenge though, not mine. I don't save scum.

I still don't get what you mean. I'm saying there is a point where if you try to save scum, you'll no longer get unique results. As if the outcome is determined a few days in advance.

The outcome is determined when the last random number was generated prior to the event happening. If you somehow generate another event in that time when you reload, you will get a different event instead.
