public interface Friend extends Entity {

  String getName();
  void setName(String name);

Friend f = jalse.newEntity(Friend.class);


Filtering entities by type (using inheritance)

public interface Animal extends Entity{}
public interface FlyingAnimal extends Animal{}


jalse.streamEntitiesOfType(Animal.class).foreach(/* Feed */);

Creating an EntityListener

jalse.addEntityListener(new EntityListener() {

  public void entityKilled(EntityEvent event) {
    if (event.getEntity().isMarkedAsType(Evil.class)) {
      /* Spawn more */

Creating an AttributeListener

entity.addAttributeListener("danger", Attributes.BOOLEAN_TYPE, new AttributeListener<Boolean>(){

  public void attributeAdded(AttributeEvent<Boolean> event) {
    if (event.getValue()) {
      /* Run like hell */

Creating and scheduling an Action

StrandedSurvivors living = jalse.newEntity(StrandedSurvivors.class);
for (int i = 0; i < 10; i++) {

living.scheduleForActor(new Action<StrandedSurvivors>() {

  public void perform(ActionContext<StrandedSurvivors> context) {
}, 0, 1, TimeUnit.SECONDS);

Adding and removing attributes

entity.setAttribute("falling", Attributes.BOOLEAN_TYPE, true);


entity.removeAttribute("falling", Attributes.BOOLEAN_TYPE);
entity.setAttribute("death", Attributes.newTypeOf(Date.class), new Date());
