Modules & Plugins

Modules

Modules are meant to hook into any of Orion's internal classes so that they may extend and/or add additional functionality. For example, PVP will not be part of Orion out of the box; but instead, a module for PVP will be created. This means servers that do not need PVP, such as lobbies, simply ignore any PVP mechanics clients attempt and therefore, save resources. On the other hand, servers that need PVP can simply load the module.

Plugins

Plugins do not have access to Orion's internal classes and instead will use the api package to interact with the server. This is a high level API that is meant to be 100% safe. A good use case for a plugin would be modifying chat format, tracking player stats, etc.
