Item Research 'n' Spawn

🎮 **Hey, a new version is here! ** 🎉

---

✨ Module Features

This mod introduces a mechanic similar to Terraria's Journey Mode and Minecraft's ProjectE mod, where you can "research" items and then create more items for free or for the cost of some currency. There are multiple modes and settings to choose from, allowing you to play the way you like, whether that's progression-friendly or straight-up cheating 😉

  • Place the item into the research area (a small animated hunger book)

Install & use Install: SMAPI mod (Stardew Valley standard)

  1. Install SMAPI first (Stardew Valley's mod loader): download it from smapi.io, run 'install on Windows.bat' and pick your game folder.
  2. Unzip the archive from playbuff and find the folder that contains manifest.json — that folder is the mod.
  3. Copy that whole folder into Stardew Valley/Mods/.
  4. Launch the game through SMAPI (run StardewModdingAPI.exe or set it as the launch option). The console before the title screen lists each mod's load result.

Cheat-style tools may not need SMAPI — unzip and run them as the readme describes. Back up your save before editing it; SMAPI lists failed mods in its console.
