Denizens are a great way to add MUD-style RPG Citizens to your server. Denizen NPCs use mini 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.

Denizen grants Citizens NPCs 2 major abilities: Interactions and Activities. Interactions occur when the player interacts with the NPC in some way, clicking, attacking, walking near, etc. These interactions trigger scripts based on conditions called 'Requirements'. Each interact script will run a series of commands to make the Denizen do or say something. Very complex gameplay can be created using these scripts. The other half of Denizen is activities. These scripts give the NPC continuous tasks to do that make them feel alive and provide useful functions. Wandering around, mining blocks, collecting items are all assignable activities. Denizens can perform multiple activities at one time, such as wandering and collecting garbage.

If you are coming from Denizen 0.6, we've attempted to compile a list for helping with migration for users upgrading who need a brief on what needs to be changed to become compatible.

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 and '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!

Change Log

Here's what's changed!

0.7.5 BETA build #455

• New! OWNER requirement will require ownership of the NPC interacting. Could be used for 'command interfaces' that only the owner can access.

• New! SNEAKING requirement requires the player be crouched when clicking. Careful on conflict with info-click for ops! Info-click can be disabled in the config.

• New! Queue-time flag replacement can let you dynamically use flag data in a script entry. For example: - GIVE <FLAG:ExampleItemFlag> QTY:<FLAG:ExampleQtyFlag>

• Experimental! Denizen NPCs now have their own Command Queue, and a TASK activity. This allows NPC's to use the activity scheduler to do tasks at certain times of the day.

• Experimental! LISTEN command implemented, KILL type implemented. Return of the 'Quester'. More types coming soon. Example usage: - LISTEN KILL ID:UniqueId TYPE:ENTITY NAME:ZOMBIE QTY:5 SCRIPT:FinishIt would require the player to kill 5 zombies. When completed, it will run the task script 'FinishIt'.

• New! Use <*> to use Chat Trigger text in EXECUTE or talk commands.

• New! Use <*> in FLAG command to remember player input. Example usage: - FLAG PLAYER_RESPONSE:<*>

0.7.5 BETA build #440:

• New! API Events make extending Denizen more powerful than ever!

• New! RUNTASK/CANCELTASK allows delayed tasks to be set, and cancelled.

• New! HOLD command can change what a Denizen NPC is wielding.

• New! Replaceable data for dynamically putting flags into texts!

• New! ISLIQUID requirement can sense if a block bookmark is solid, or liquid.

• New! IF command can evaluate a FLAG and run a TASK script.

0.7 BETA builds #125 - #280:

• Updated! Less bugs! We're still in beta, but there has been some major code cleanup!

• New! Triggers, Commands, Requirements and Activities are now extensible by plugin programmers. See: Custom Denizen Commands on the Citizens2 Wiki. Documentation coming soon!

• New! Debug Mode will let you see the logic of interaction and script execution to help you find problems in scripts faster than ever. I'm striving to make this as informational and clean as possible to help you test your scripts and get good feedback on behavior.

• New! Info-Click lets you see Denizen stats and specifics, such as script assignments, trigger status, activity schedule and associated bookmarks with just a crouch and a click. Requires OP.. use this!

• New! Proximity Triggers can trigger a script when a Player comes near. The most requested trigger type I got during the previous betas.

• New! Location Triggers can trigger a script when a Player walks over a Location Bookmark. This is kind of like a PLAYERTASK LOCATION, but better! :)

• New! Damage Triggers separate the left and right clicks for more control over interaction. Look forward to a whole new set of commands to go along with this!

• New! Script Overlay mode is a whole new way to assign a script. Less copying/pasting when working with multiple scripts, not to mention more control! If you're an advanced script-user, this is for you!

• New! ANNOUNCE command can make global server announcements.

• New! RANDOM command will leave command execution to chance. Duck-duck-goose.

• New! HINT command will hint to the Player acceptable Chat Triggers for the current step and script. Language support coming soon!

• New! FLAG command lets you set 'flags', on players to store progress, important information, or other variables that can be used with the FLAG requirement. This is HUGE!

• New! FLAG requirement can require special flags and values to be set in order to be eligible for a script. Again, this is HUGE!

• New! POWERED requirement can check if a block bookmark has redstone power. Great idea, instinx!

• New! The activity engine has been implemented which will allow your Denizens to do things on their own. There's a whole lot more to this concept, but you can try out the new WANDER activity in all its glory. This thing is cool, and customizable!

• New! In-game commands now let you easily manage triggers, bookmarks, and debug info.

• Updated! Extended/unified command syntax for almost every existing command. Once you get over the pain of upgrading, you will drop a jaw at the new capabilities!
