by AshPapi

Players who want scripted characters with dialogue trees, quests and story chains can use interactEntity, a Forge mod for 1.20.1 that turns mob entities into NPCs configured through JSON.

What it does

A mob can be turned into a scripted NPC with branching dialogues, quests and conditional choices, all defined in simple JSON files. Dialogue options can be hidden or shown based on conditions, and one NPC's actions can trigger another, which lets authors build multi-NPC story chains. NPCs can also appear in the world on join, or when a player walks into a defined zone.

The mod targets 1.20.1 on Forge only, with the latest file 2.2.2-1.20.1 published 2026-07-05. Because it runs on client and server, both the server and every player need it. Java is required to use it, and the author notes that file-based coding is needed to write the scripts. The project is open source under the MIT License and first appeared 2026-04-28.

Key features

  1. Branching dialogues

    Dialogue options carry visibility conditions, so a player sees only the choices that apply to their progress.

  2. Quest system

    Quests are tracked on a HUD tracker and in a journal opened with the J key.

  3. Conditions and actions

    19 conditions test values such as health, hunger, time, weather, biome and kills, while 28 actions give or remove items, run commands and play effects.

  4. Shared progress

    Variables and reputation are kept in a global scope, so progress is shared across players on a server.
