Class EntityBuilder

java.lang.Object

com.artemis.utils.EntityBuilder

public class EntityBuilder
extends Object

Non-reusable entity creation helper for rapid prototyping. Discouraged for use other than rapid prototyping and simple games. Use ComponentMapper instead. Example: new Builder(world) .with(Pos.class, Anim.class) .tag("boss") .player("player1") .group("enemies") .build();
