A real little map engine for the Stardew World Workshop: paint with layers and tile rules, fill and undo, take on challenges, walk-test your world, set a doorway warp, write your files, debug a SMAPI log, save or share your world, then download your mod. It runs on a locked-down school computer.
Ground goes on Back, objects on Buildings, things that draw over the player on Front.
In Stardew a doorway is a Warp value on the map: fromX fromY toArea toX toY. Set the two doorways below, then test the walk. A doorway with no way back strands the player.
The Farm door is at tile 8,4. Its value 8 4 Cabin 2 4 means: step on 8,4 and arrive on Cabin at 2,4. The Cabin door does the trip back.
This loads your map over the game's Maps/<name> without touching the original. Format tells Content Patcher which fields you use.
Click the red line, then choose the fix. White lines are normal.
This bundles everything you made into a real mod folder and downloads it as a zip: manifest.json, content.json, your map as a .tmx, and a README. Drop the unzipped folder into Stardew Valley / Mods.
Tip: the target area must already exist. To send the player to a brand-new area, register it in Data/Locations first (see Episode 8).
This is a little map editor. In a few steps you will paint a world, set its rules, play it and save it.
