Generando una Entidad

Necesitaras tres cosas para generar una Entity: una Location, una Extent, y una EntityType. El proceso para obtener estos es bastante simple, solo necesitas tener tu``Location``de algun lugar de tu codigo de complemento y elegir el tipo de``Entity`` que deseas generar.

Por ejemplo, intenta crear un Creeper:

import org.spongepowered.api.entity.Entity;
import org.spongepowered.api.entity.EntityTypes;
import org.spongepowered.api.event.CauseStackManager.StackFrame;
import org.spongepowered.api.event.cause.entity.spawn.SpawnTypes;
import org.spongepowered.api.world.Location;
import org.spongepowered.api.world.World;

import java.util.Optional;

public void spawnEntity(Location<World> spawnLocation) {
    World world = spawnLocation.getExtent();

    Entity creeper = world.createEntity(EntityTypes.CREEPER, spawnLocation.getPosition());

    // We need to push a new cause StackFrame to the stack so we can add our own causes
    // In previous versions of the API you had to submit a Cause parameter
    // that would often not contain the real root cause
    // By default the current plugin's PluginContainer is already pushed to the stack.
    try (StackFrame frame = Sponge.getCauseStackManager().pushCauseFrame()) {
        frame.addContext(EventContextKeys.SPAWN_TYPE, SpawnTypes.PLUGIN);
        world.spawnEntity(creeper);
    }
}

Esto tomara del mundo nuestra``Location``, la cual necesitaremos para generar actualmente. Despues, usa EntityUniverse#createEntity(EntityType, Vector3d)`para crear la entidad, pero tenga en cuenta que esto no generara la entidad dentro del mundo,solo va a crearla, nosotros necesitaremos especificar el tipo de``Entity` a generar, y las co-ordenadas de su``Location``.

Once we have created our Entity we can then use the world for spawning the Entity. We should specify a Cause for the spawning so other plugins can handle it accordingly. For spawning Entitys, it is best to use a SpawnType as part of the context. In this example, we stated that our entity was spawned from a plugin, however we can make it any cause/context that best describes why we are spawning this in, such as a mob spawner (See SpawnTypes#MOB_SPAWNER), or spawn egg (See SpawnTypes#SPAWN_EGG).
