Alternatively, you can help the project by starring the repository or telling others about NPCLib. :smile:
## Roadmap
- :heavy_check_mark: Spawn and destroy NPC (version 1.8 - latest).
- :heavy_check_mark: Autohide NPC when out of range.
- :heavy_check_mark: Add support for 1.7.10 (1.7 R4).
- :construction: Option to rotate head to player (when nearby).
- :construction: Add support for animated text (update-able holograms).
- :x: Give NPC armor and items in hand.
- :x: Multi-line text support for 1.7.10 (1.7 R4).
### Roadmad Legend
:heavy_check_mark: Feature is fully implemented and functional. <br>
:construction: Feature is still in development (or experimental). <br>
:x: Development of feature has yet to be started. <br>
