Stardew Predictor As many are aware, several of Stardew Valley's mechanics aren't all that random. The most well-known is probably the way "mushroom levels" and infestations in the mines persist throughout a day and seemingly travel "upward" through the mines as the days progress. This app reads a save file (or takes a game ID number) and simulates the pRNG calls to predict such events. It is somewhat cheaty, but hopefully still interesting and useful to those who choose to try it. Since all the predictions are based on the game ID and other information from the save file, it's only useful for people playing on the PC & Mac versions. Currently, the following items are predicted: All mushroom levels, regular monster infestations, and slime-only infestations in the mines. This is presented in a calendar format and is scrollable a month or year at a time. Items available from the Traveling Merchant Cart. This is browsable by week or searchable within various timeframes. The Wednesday fish and Saturday cooked item sold by Krobus in the sewers. Searchable. Wallpaper and flooring items sold by Pierre and the Joja Mart. Contents from cracking open geodes at Clint's shop. Currently only browsable by geode count, I'll probably be adding searching to this too as well as adding an indicator on those minerals which still need to be donated. Note that both of those features are available in-game using the Geode Info Menu mod. Trains passing by at the Railroad. Note that if you load/reload a save on the day of an expected train, the train will not spawn. Various overnight events on the farm. This is just the chance that the event is chosen and checked; additional spawning conditions could still prevent the event from happening. Feast of the Winter Star gifting assignments. Primarily useful if you didn't write down your designated gift recipient or want a sneak peek at who will be giving a gift to you. The app is accessible at https://mouseypounds.github.io/stardew-predictor/. To see a preview without running your own save through it, you can supply an ID to the URL like this: https://mouseypounds.github.io/stardew-predictor/?id=157948696. For anyone who uses it, please let me know here about any feedback or suggestions. Also special thanks to @margotbean whose comments over on the wiki helped get development moving again. Frequently Asked Questions (FAQs) Can you add the Dish of the Day sold at the Saloon? Unfortunately, the RNG seed used for that includes the number of steps taken, so that is not predictable long-term.
