Denizen is a great way to add complex interactive role-playing NPCs to your server. Denizen NPCs use scripts with steps and events to interact with the player and world. Imagine interactive gate-keepers, magical wizards, experience trainers, bankers, talking townspeople and more! They can be used in thousands of different ways, from tutorials, to questing, to administrating.. your imagination is just about the limit! Though Denizen uses Scripting, it is not to be confused with Citizens2 Core Scripting which utilizes JavaScript and other major scripting languages to implement Goals. Instead, Denizen uses its own YML scripting language which is designed to be easily read and edited by hand.

How it works

Denizen is an extension of Citizens2 that adds an incredible amount of interactivity and automation to NPCs and Players with some of these major features:

• The Script Engine carries out and sends all the commands to be executed in an orderly and predictable fashion; this is the backbone of Denizen. Currently has 3 queues, one for the Player, one for Denizens, and one for Tasks. There's not much to see on the outside, this is the interworkings of Denizen, but rest assured that this is high performance machine behind the scenes!
• Interact Scripts are the meat of Denizen, allowing Players and NPCs to interact with each other and the world. These are highly customizable with 20+ requirement types, 40+ script commands, and thousands of different ways to use them together. This with the Denizen Script Engine also allows commands to help control the rest of Denizen with script flow commands and such.
• Activity Scripts are exciting. Imagine Johnny Appleseed planting trees, on his own, or simple villagers wandering around and socializing. Activities, of course, work with the rest of Denizen's other functions and features, allowing hundreds of ways to use Activities to add automation and liveliness to your world.
• Activity Scheduler takes Activity Scripts one step further, allowing Denizen NPCs to have daily schedules, based on the Minecraft day, to allow certain functionality to different times of the day. This also enables certain Script Commands to be executed and carried out, as well.
• Task Scripts are simple scripts that can be carried out in a variety of different ways. These can be used along side both Activity and Interact Scripts, but perhaps the most powerful way to use them is by allowing your plugin to utilize them, if you're a developer, or using other plugins that harness the ability to run a Denizen Task Script as well.
• Listeners are currently in an 'experimental phase', but are already allowing control over minecraft and bukkit events like nothing other. This already allows scripts to keep track of and assign 'quest-like' objectives, such as a 'kill quest', if you're familiar with the C1 Quester. But whereas many quest plugins are limited to this feature alone, Denizen, of course, allows you to use this in addition and along side the rest of the plugin, making room for extremely dynamic and intricate 'quest scripts'.
• Flag System is the key to Denizen being dynamic. An intricate, yet easy to learn 'Flag/Variable' system has been implemented into Denizen to help keep track of events, items, numbers, players, and more. The new Flag System is still getting more powerful each and every day.. it's the key to a spectacular script is sure to have a flag or two.
• Extensible Commands/Requirements/Activities and more make it easy to add-on to Denizen with very little Java knowledge. This also makes it extremely easy to let users utilize your plugin with script commands. Denizen also has API Events to use.
• Denizen Debugger' is an extremely friendly and informative way to test out scripts and interactions. Commands, events, and interactions are all logged in an easy to read format to show the exact progression of a script and its surroundings. No more guessing! Less headaches!

Seem overwhelming? Stop! Start small! Denizen is easy, Denizen is simple. But. Denizen is hard, Denizen is complex. Simply put: Denizen is what you make it! Our advice? Start small, and build upon what you have. Read the wiki articles, watch the youtube videos, test our your scripts, and test out some of the sample scripts! Before you know it, you'll be a Denizen poweruser, drunken with power, just like us!
