This interface is extended by all events that have a player.
That means you can use the getter below to access the player.

It might be required to import the class to avoid errors.
import crafttweaker.event.IPlayerEvent;

This interface extends ILivingEvent, which means that all functionality that ILivingEvent offers is also present in IPlayerEvent
