MyNPC

MyNPC 1.1 User Guide

Requirements

• Minecraft 1.20.1
• Forge 47.x
• MyNPC 1.1

Installation

1. Put the MyNPC jar into your instance mods folder.
2. Start the game once.
3. The mod will create config folders automatically.

Important folders:

• config/npc_types stores NPC definition JSON files.
• config/mynpc_custom_assets/textures stores custom NPC skin textures.
• config/mynpc_custom_assets/sounds stores custom NPC sound files.
• config/mynpc_custom_assets/lang can be used for extra language entries.

Default Guide NPC

The built-in guide NPC is village_guide.

By default, the guide:

• Spawns in vanilla villages.
• Has a 100% spawn chance when the village spawn check succeeds.
• Spawns at most one guide per village area.
• Knows a random set of structures.
• Can sell structure location help and teleport scrolls.
• Can fight hostile mobs, retaliate when attacked, and avoid creepers.
• Stays near its home village instead of wandering freely.

If the default config was already generated before updating, delete config/npc_types/village_guide.json and restart the game to regenerate the latest default version.

NPC Manager

Press H in game to open the NPC manager.

Main actions:

• + creates a new NPC from the default template.
• Select an NPC from the left list to edit it.
• Use the small box beside NPC entries for multi-select.
• Save saves current changes.
• Copy duplicates the selected NPC. The copy keeps most settings but gets a unique id.
• Cancel discards the current edit session.
• Delete removes selected NPC definitions after confirmation.
• Reset restores selected NPCs to the built-in default guide settings.

Tabs:

• Look: skin, name, entity id, and sounds.
• Behavior: spawn structures, spawn chance, and min/max spawn count.
• Structure: known structures and structure hint behavior.
• Trade: teleport scroll trades and custom item trades.
• Chat: random chat lines and structure-related dialogue.

Custom Skins

1. Put PNG skin files into config/mynpc_custom_assets/textures.
2. Open the NPC manager with H.
3. Select an NPC.
4. Go to Look.
5. Use the custom skin button to choose a texture.
6. Save the NPC.

The skin should use the normal Minecraft player skin layout.

Custom Sounds

1. Put sound files into config/mynpc_custom_assets/sounds.
2. Open the NPC manager with H.
3. Select an NPC.
4. Go to Look.
5. Choose sounds for interaction, hurt, death, or ambient slots.
6. Use the preview button to test sounds.
7. Save the NPC.

Structure Selection

Structure lists support:

• Search by keyword.
• Clicking the structure name for single selection.
• Clicking the small box for multi-selection.
• Scrolling when the list is longer than the panel.

Structure names use language keys where available. Unknown structures fall back to a readable id-based name.

Trading

NPCs can offer:

• Teleport scroll trades for known structures.
• Structure location hint trades.
• Custom item trades.

For each structure trade, you can configure:

• The structure name.
• The item used as currency.
• The required item count.
• Whether the structure trade is disabled.

Chat And Hints

NPCs can have general chat lines and structure-specific hint text.

Structure hint text can use:

• {structure} for the translated structure name.
• {direction} for the direction text.

Example:

If my memory serves, {structure} lies somewhere to the {direction}.

Spawn Eggs

Spawn egg NPCs use the same base initialization as naturally spawned NPCs:

• Default known structures can be generated.
• Home position is set when spawned.
• Random equipment can be assigned.
• Combat behavior is enabled.

Troubleshooting

If a custom skin shows as missing texture:

• Check that the file is inside config/mynpc_custom_assets/textures.
• Make sure it is a valid PNG.
• Reopen the selector and save the NPC again.

If a custom sound does not play:

• Check that the file is inside config/mynpc_custom_assets/sounds.
• Use the sound preview button in the Look tab.
• Restart the game if the asset pack was just created for the first time.

If the default guide settings look old:

• Delete config/npc_types/village_guide.json.
• Restart the game.
• The mod will regenerate the latest default config. ——————————————————————————

MyNPC 1.2 Update Guide

This guide covers the main new workflows added or changed in MyNPC 1.2.

Opening the NPC Manager

• Press H to open the custom NPC manager.
• Use the NPC list on the left to select an NPC.
• Use the search box under the NPC list to filter NPCs.
• Use the + button beside the search box to create a new NPC.
• The selected NPC now appears pressed in the list, matching the selected page tabs.

NPC Ids and Defaults

• The built-in guide NPC still uses the display name village_guide.
• Its internal id is now npc.
• New custom NPCs use ids like npc1, npc2, and npc3.
• Reset restores the shared default guide settings while keeping a safe unique id for the edited NPC.

Spawn Eggs

• MyNPC spawn eggs are now placed in their own creative tab.
• Use /mynpc egg <npc_id> to create a spawn egg for a specific NPC.
• The command supports suggestions, so you can type part of an NPC id and pick it from the command list.

Commands

/mynpc egg <npc_id>

Gives the player a spawn egg for the selected NPC definition.

Examples:

/mynpc egg npc

Gives the default guide NPC spawn egg.

/mynpc egg npc1

Gives the spawn egg for the custom NPC with the id npc1.

The command supports Minecraft-style suggestions. Type part of an NPC id, then use the command suggestion list to choose the correct NPC without typing the full id.

This is useful when a pack contains many custom NPCs and you do not want every spawn egg mixed into the normal creative inventory workflow.

Appearance Page

• Set the NPC display name and entity id.
• Choose a custom skin from the custom asset folder.
• Reset the skin back to Steve when needed.
• Configure interaction, hurt, death, and ambient sounds.

Behavior Page

• Use Spawn Structures to edit where an NPC can naturally spawn.
• Each spawn rule contains:
  • Structure id
  • Minimum spawn count
  • Maximum spawn count
  • Spawn chance
• Use the search field and + button in the spawn rule screen to add structures.

Structure Page

The Structure page is now simplified.

• View Known opens the known-structure rule list.
• Random known max controls the maximum number of known structures selected for a naturally spawned NPC.
• Random known min controls the minimum number of known structures selected for a naturally spawned NPC.

Known-structure rules can be used to control which structures an NPC can know about and how likely each structure is to be selected.

Trade Page

• Use the custom trade list to add and manage normal item trades.
• Custom trades are shown before scroll trades in the right-click trade GUI.
• Use the teleport scroll price list to configure structure scroll trades.
• Item id fields can be typed manually or selected with the item icon button.
• Trade text can be customized for before-trade and after-trade messages.

Chat Page

• The old separate Add Text button has been removed.
• Use View Text to manage chat lines.
• In the text list editor, add, edit, or delete chat lines from one place.
• Use the structure text tools to configure structure-related dialogue.

Structure Guide

• Press G to open the structure guide.
• When the player reaches a tracked structure, the guide entry is marked as visited.
• The guide can show the tracked structure name and distance using the config options.

Custom Assets

Custom skins and sounds are loaded from the custom asset folders under the MyNPC config area.

• Put textures in the texture folder.
• Put sounds in the sound folder.
• Reopen the relevant picker screen to refresh and select the asset.

Notes for Modpack Authors

• Existing NPC JSON files are not deleted automatically.
• New installs use npc.json for the default guide definition.
• Older village_guide.json files remain compatible.
• For large NPC packs, use the /mynpc egg command and the dedicated MyNPC spawn egg creative tab to avoid clutter.
