| Name | ObjectTags |
| Description | ObjectTags are a system put into place by Denizen that make working with things, or 'objects',
in Minecraft and Denizen easier. Many parts of scripts will require some kind of object as an argument, identifier/type, or such as in world events, part of an event name. The ObjectTags notation system helps both you and Denizen know what type of objects are being referenced and worked with. So when should you use ObjectTags? In arguments, event names, replaceable tags, configs, flags, and more! If you're just a beginner, you've probably been using them without even realizing it! ObjectTag is a broader term for a 'type' of object that more specifically represents something, such as a LocationTag or ScriptTag, often times just referred to as a 'location' or 'script'. Denizen employs many object types that you should be familiar with. You'll notice that many times objects are referenced with their 'ObjectTag notation' which is in the format of 'x@', the x being the specific notation of an object type. Example: player objects use the p@ notation, and locations use l@. This notation is automatically generated when directly displaying objects, or saving them into data files. It should never be manually typed into a script. Let's take the tag system, for example. It uses the ObjectTags system pretty heavily. For instance, every time you use <player.name> or <npc.id>, you're using a ObjectTag, which brings us to a simple clarification: Why <player.name> and not <PlayerTag.name>? That's because Denizen allows Players, NPCs and other 'in-context objects' to be linked to certain scripts. In short, <player> already contains a reference to a specific player, such as the player that died in a world event 'on player dies'. <PlayerTag.name> is instead the format for documentation, with "PlayerTag" simply indicating 'any player object here'. ObjectTags can be used to CREATE new instances of objects, too! Though not all types allow 'new' objects to be created, many do, such as ItemTags. With the use of tags, it's easy to reference a specific item, say -- an item in the Player's hand -- items are also able to use a constructor to make a new item, and say, drop it in the world. Take the case of the command/usage '- drop diamond_ore'. The item object used is a brand new diamond_ore, which is then dropped by the command to a location of your choice -- just specify an additional location argument. There's a great deal more to learn about ObjectTags, so be sure to check out each object type for more specific information. While all ObjectTags share some features, many contain goodies on top of that! |
