Welcome to the documentation for the CommandAPI. The CommandAPI lets you create vanilla Minecraft commands which utilize the new command features which were implemented in Minecraft 1.13, including but not limited to:
- Having commands compatible with the vanilla
- Having commands which can be run using Minecraft functions
- Having better auto-completion and suggestions
- Having command type checks before execution (e.g. ensuring a number is within a certain range)
This is a pretty important section, I would recommend reading before implementing the CommandAPI in your own projects. This section tells you about setup which is not stated anywhere else in the documentation. Think of it as the "knowledge you should know before using this API".
The CommandAPI does not follow the "standard" method of registering commands. In other words, commands which are registered with the CommandAPI will be registered as pure vanilla Minecraft commands as opposed to Bukkit or Spigot commands. This means that the following implications exist:
- Commands do not need to be declared in the
- Commands are not "linked" to a certain plugin. In other words, you cannot look up which commands are registered by which plugin.
This documentation is split into the major sections that build up the CommandAPI. It's been designed in such a way that it should be easy to find exactly what you want to help you get started with the CommandAPI, and how to make effective use of it. Each step of the way, the documentation will include examples which showcase how to use the CommandAPI.
You can use the side bar on the left to access the various sections of the documentation and can change the theme to your liking using the paintbrush icon in the top left corner.
Using the search icon in the top left corner, you can search for anything in this entire documentation. For example, typing "Example" will show a list of examples which are included throughout the documentation.
