Hey there! Thanks for using Denizen for Bukkit and Citizens2. Looking for a quick starting guide? Here's the place!

So, what is Denizen? It's is best classified as a scripting platform. Denizen for Bukkit and Citizens2 utilizes the scripting, and various other components provided by DenizenAPI. The scripting component of Denizen features easy to use script containers, replaceable tags, commands, and a queue system. Built aside is a slew of components that deal with many kinds of event handlers, many additional NPC features, a fully-featured variable system (we call them 'flags'), and a rich object-oriented set of features. I encourage users to start small when first getting into Denizen, but rest assured there are tons of features to explore.

Denizen NPCs? Yep, that's right. Denizen is probably best known as a way to create scripted Citizen NPCs. In fact, this whole project started out as an extension to Citizens2. You can use it to make interactive NPCs with the use of Assignment Scripts and Interact Scripts. This is pretty easy to do, and there's a bunch of cool NPC specific (among many other) commands and tags that you can utilize as well.

Here's a small example I call 'cookies'. I normally like to comment my scripts, but this one below is presented without any as to show the flow.

  type: assignment 
  interact scripts: 
  - 100 Cookie Handler 

Cookie Handler:
  type: interact 
    'Spreading the Word*': 
      click trigger: 
        - random 3 
        - chat 'I like cookies!' 
        - chat 'MMmm.. cookies are favorite!' 
        - chat 'Cocoa and wheat me freak!' 
      chat trigger: 
          trigger: 'I love /cookie/s!' 
          - chat 'Me too!' 
          - narrate '<> gives you some cookies.' 
          - give i@cookie qty:6 
          - zap 'step:Cookies given' 
    'Cookies given': 
        click trigger: 
            - chat 'How were the cookies?' 
            - zap 'step:Spreading the Word'

It's a simple 2-step, multi-trigger script that creates a cookie loving NPC. For some reason I think it's funny to name the NPC 'Notch'. Making a NPC use this script couldn't be easier, either. Simply use a bukkit command while having the NPC selected. It looks like this:

/npc assignment --set cookies

Now clicking on your NPC will use Denizen Triggers to activate the script above. An instant Denizen NPC! Cookies is funny, but hardly useful, and it's my personal philosophy that NPCs should be useful. How 'bout a simple healer? This NPC will heal you, but only when you're seriously injured.

Basic Healer: 
  type: assignment 
  interact scripts: 
  - 100 heal me, bro! 

Heal me, bro!: 
  type: interact 
    "Need a heal?*": 
      click trigger: 
        - if '<>' < '<m:<> / 2>' { 
            - look <player.location> 
            - chat 'Woah dude, you are <>! You could use a heal!' 
            - chat 'Just give me another click to get some power!' 
            - zap "Healin'" duration:30s 
          } else { 
            - look <player.location> 
            - chat 'Nice an healthy. Keep it up!'  
      click trigger: 
        - ^zap 'need a heal?' 
        - ^engage 
        - chat "Here goes nothin'!" 
        - playeffect instant_spell <npc.location> qty:25 
        - playeffect heart <player.location> qty:25 offset:1 
        - heal <player> 
        - disengage

How do you make a Healer NPC with this script? You guess it! Just select that NPC, and type:

/npc assignment --set 'basic healer'

It's not just for NPCs. I guess I already told you that, but Denizen has some other script types that open up possibilities that extend far beyond it's core functionality of utilizing NPCs. One of my favorite 'simple scripts' that I like to show people is one that my friend Blankiito showed me. The one below is slightly modified, but basically it enables a 'rogue-like feature' that makes a player invisible when sneaking. It's a simple concept, but perfectly illustrates the flow of a Denizen Script.

  type: world 
  debug: false 
    on player starts sneaking: 
    - playeffect <p.location> magic_crit qty:10 
    - invisible <player> state:true 

    on player stops sneaking: 
    - invisible <player> state:false

Even small scripts can be incredibly useful for your server. Sometimes scripts can replace entire bukkit plugins, and since the 'code' is in Denizen Script, the end result is often times more flexible to you, the server operator. Have a plugin that run some commands every once in awhile? Replace it with a simple Denizen script.

Auto Save Event Handler: 
  type: world 
  debug: false 
    on 5:00 in w@world:  
    - announce 'Autosaving...' 
    - execute as_server 'denizen save' 
    - execute as_server 'citizens save' 
    - execute as_server 'save-all'

Use Denizen to solve problems, or to make features easier to use. Example: If you're familiar with Citizens, you may have realized that WorldGuard's /butcher command is not friendly to mob-type NPCs. It removes them, too, which can be a pain! Why not write your own /butcher command?

Safer Butcher Handler: 
  type: world 
  debug: false 
    on sbutcher command:  
    - narrate 'Removing all mob entities within 15 blocks... your NPCs are safe!'  
    - foreach <player.location.find.entities.within[15]> {  
        - if <%value%.is_mob>  
          remove %value%  

Denizen Quests are the best quests. If you're like me, this whole thing started by using the Quester for Citizens1. It featured a fairly simple questing structure to implement things like 'kill quests' and 'collection quests'. When Citizens went to version 2, that functionality was no longer 'core', but no worries Denizen can help! By utilizing Denizen's Player Listeners, simple questing can be done easily, and it's more robust because you can use all the other features implemented by Denizen, too!

So, how do you best get started? This is a question we get all the time. Because of the enormous amount of ways to use and customize Denizen, we suggest that you simply START SMALL! Checking out the videos, scripts, and articles on denizen-docs you're sure to find a comfortable place to start. While scripting, utilize the tools provided, such as the SublimeText2 grammar pack, and the reference and search for meta lookup on this site.

Like any programming language, there is a learning curve with code structure and syntax that will only be overcome by trial and error. While using some user-made scripts can be as easy as dragging-and-dropping, many scripts will likely require at least a basic understanding of the denizen-script structure to fully utilize their features. But don't worry! Denizen is purposefully made to be easy to read and easy to customize! Tags, commands and events are all very verbose, easy to follow. With a little bit of research we know you'll soon be drunken with power, just like us!

    Kind of a specific item, but for listeners is it possible to use meta info? I cant use names since this is FTB. It works with ID's that dont have meta, but something like this doesnt work

    - listen block type:break block:1475:3 qty:20 region:QCra1A script:QCra1A

    Is there a way to get it to work with ID with a sub meta like how pink wool is 35:6?

    @speedsnip: Go

    WorldGuard has to allow mob spawning in the region for you to be able to spawn entities there. (WorldGuard blocks even plugin-based spawning for some reason). It is most definitely an implemented command, and works fine outside WG regions.

    WorldGuard doit permettre mob frai dans la région pour vous d'être en mesure de frayer entités là. (Blocs WorldGuard même de frai plugin-base pour une raison quelconque). Ce est très certainement une commande mis en œuvre, et travaille fines régions WG extérieur.

    @junksintrunk: Go

    I'll add you on skype.

    @k2water: Go

    The latest version of craftbukkit is CB 1.7.10-R0.1 dev - and that is what the latest release is built against. If you do not have access to a copy of 1.7.10 craftbukkit, you'll have to use an older release of Denizen.

    If you look at the title of the Denizen release, it says (1.7.10) IE, built for CB 1.7.10. Use the one labeled (1.7.9)
