Shoots boats, not arrows!

BoatArrows.js

function entityAddedHook(entity) {
	if(Entity.getEntityTypeId(entity) == EntityType.ARROW) {
		var entity2 = Level.spawnMob(Entity.getX(entity), Entity.getY(entity), Entity.getZ(entity), EntityType.BOAT);
		Entity.setVelX(entity2, Entity.getVelX(entity));
		Entity.setVelY(entity2, Entity.getVelY(entity));
		Entity.setVelZ(entity2, Entity.getVelZ(entity));
		Entity.remove(entity);
	}
