The mod is still in public test, please submit an issue if you find any problems. If you want to use the latest version, please compile the source code yourself, see Build.

Chinese Version

1. Introduction

Chat With NPC allows players to freely chat with NPCs, who will answer questions based on his setting (Basic Prompt) and the setting of their Groups (Nation, City, Town ,etc.). Suitable for RPG maps or puzzle maps. The NPCs would not change the game rule (if you don't use the advanced features). NPC can also perform some actions based on the chat content if you define it.

In the future version, we will add innovative features such as NPCs chatting with each other, NPCs' viewpoints on events, etc., so that NPCs in the same Group can interact with each other.

2. How to use

Any player can talk to NPCs by shift+clicking on them, if the NPC has been registered by OPs. Then the NPC will greet with players.

The NPC's speech can be seen by everyone (in the chat bubble above their head), or by players within a certain range around NPC (in the Chat bar).

Any nearby players can reply to the NPC in the chat bar directly (or the nearest NPC if there are multiple NPCs near the player).

If you are administrator, see the Installation for more information.
