Entity Interface. Used to obtain and modify information entities' data.
Entities are everything that is freely movable in the world such as players, monsters, items on the ground any many more.

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import.
import crafttweaker.entity.IEntity;

IEntity extends ICommandSender. That means that all methods that are availabel to ICommandSender Objects also are available to IEntity Objects!
