Now, before i say anything. I want to show you this. -CLICK HERE- I have only realized that MineCraft existed last week. And am loving it, So much that I made my own private server for me and my friends to play on. But something is lacking. There is no Life in the world! I want to discuss the possibility, predicted requirements, ideas and/or predicaments of creating a plug-in for bukkit which creates NPC's that not only Move and interacts with players. But also builds, gathers and defends themselves when attacked by mobs/players?. If you were going to make a plugin like this, how would you do it? what programs would you use? Does it require a database? ( 99% chance it probably will ). I have tried substituting my current server with Citizens and npcx to try and recreate even a portion of Millenaire, Which works out fine. ( I have shops and Guards with a few bandits running around). But its still not at a point where they will surprise you when you go mining for a few days and come back just to see that there is now a massive castle in the middle of town! I am calling out to all Developers and forum members to share your Thoughts and Ideas about this topic.
