NPC Creator

“NPC Creator” is a mod that lets you create NPCs for your game, making it a tool for map creators. The unique feature of this mod is that it uses JSON scripts, which work from your config folder. This means that every world the player launches will have these NPCs at predefined locations, and be updated whenever you push a update to the scripts in a update to your modpack.

This is especially useful for map creators who want to allow players to use old saves while updating certain NPCs. With this mod, players don’t have to lose their saves, they can simply update the modpack as usual, and any changed NPCs will be updated automatically.

We may add more features over time, but for now, the mod supports:

• Conversations
• Skins
• Custom shops

To use this mod: 

• Launch a world to generate the “npccreator” folder.
• Manually create a folder called “skins” inside the “npccreator” folder, alongside the “npc”, “dialog”, and “shop” folders.

Creating an NPC with Dialog:

To create an NPC with dialog, make a JSON file and format it like this:

{
  "name": "Test",
  "posX": 286,
  "posY": 38,
  "posZ": 1106,
  "direction": "south",
  "skin": "Test",
  "dialog": "Chat1"
}

This creates an NPC named “Test”, places it at specific coordinates, and assigns it the skin “Test” (if a corresponding image is placed in the skins folder). The NPC will use the dialog file “Chat1” when interacted with.

Creating Dialog Conversations:

To create a conversation, go to the “dialog” folder and create a file called “Chat1” (as referenced in the NPC setup). This defines an interaction where the NPC says “Welcome”, and the player can respond with two choices:

• “Eeeeeh, okay?” → Redirects to another dialog file (“Chat2”)
• “Bye” → Ends the conversation

{
  "question": "Welcome! TEXT TEXT TEXT",
  "responses": [
    {
      "answer": "Eeeeeh, okay?",
      "type": "next",
      "action": "Chat2"
    },
    {
      "answer": "Bye",
      "type": "close"
    }
  ]
}

Creating an NPC with a Shop:

If you want an NPC to have a shop instead of dialog, use a similar format, but include a “shop” tag with a shop name:

{
  "name": "TestShop",
  "posX": 296,
  "posY": 27,
  "posZ": 1056,
  "direction": "south",
  "skin": "TestShop",
  "shop": "TheShop"
}

Creating a Shop:

To create a shop called “TheShop”, make a JSON file named “TheShop”. In this example, players can buy an Enchanting Table using a currency item called “minecraft:dirt”:

{
  "items": [
    {
      "name": "Enchanting Table",
      "costOne": {
        "item": "minecraft:dirt"
      },
      "type": "itemstack",
      "data": {
        "item": "minecraft:enchanting_table"
      }
    },
    {
      "name": "Bookshelf",
      "costOne": {
        "item": "minecraft:dirt"
      },
      "type": "itemstack",
      "data": {
        "item": "minecraft:bookshelf"
      }
    },
    {
      "name": "Anvil",
      "costOne": {
        "item": "minecraft:dirt"
      },
      "type": "itemstack",
      "data": {
        "item": "minecraft:anvil"
      }
    }     
  ]
}

You can also set the “type” to “Command”, allowing commands to be executed when the shop is used.
