This interface is extended by all Events that relate to projectiles (suchs as fireballs, arrows and throwable items).

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

This interface extends IEntityEvent, which means that all functionality that IEntityEvent offers is also present in IProjectileImpactEvent.
