Özel olaylar

You can write your own event classes and dispatch those events using the method described above. An event class must extend the Event class. Depending on the exact nature of the event, more interfaces should be implemented, like Cancellable for events that can be cancelled by a listener or interfaces like AffectEntityEvent clarifying what sort of object is affected by your event.

You can extend AbstractEvent for common methods to be implementated for you

Örnek: Özel Olay Sınıfı

The following class describes an event indicating a ServerPlayer has come in contact with FLARD and is now about to mutate in a way specified by the event. Since the event can be cancelled by listeners, it implements the Cancellable interface.

Genellikle özel olayların diğer eklentiler tarafından dinlenmesi amaçlandığından,bunları uygun bir şekilde belgelemek sizin yararınızadır.Bu, tipik olarak: javadoc: `Cause`de bulunan nesnelerin listesini içerir. Aşağıdaki örnekte,muhtemelen ana sebebin hayali “FLARDSource” sınıfının bir nesnesi olduğu söylenebilir.

import org.spongepowered.api.entity.living.player.server.ServerPlayer;
import org.spongepowered.api.event.Cancellable;
import org.spongepowered.api.event.Cause;
import org.spongepowered.api.event.impl.AbstractEvent;

public class PlayerMutationEvent extends AbstractEvent implements Cancellable {

    public enum Mutation {
        COMPULSIVE_POETRY,
        ROTTED_SOCKS,
        SPONTANEOUS_COMBUSTION;
    };

    private final Cause cause;
    private final ServerPlayer victim;
    private final Mutation mutation;
    private boolean cancelled = false;

    public PlayerMutationEvent(ServerPlayer victim, Mutation mutation, Cause cause) {
        this.victim = victim;
        this.mutation = mutation;
        this.cause = cause;
    }

    public ServerPlayer victim() {
        return this.victim;
    }

    public Mutation mutation() {
        return this.mutation;
    }

    @Override
    public boolean isCancelled() {
        return this.cancelled;
    }

    @Override
    public void setCancelled(boolean cancel) {
        this.cancelled = cancel;
    }

    @Override
    public Cause cause() {
        return this.cause;
    }
}

import org.spongepowered.api.event.Cause;
import org.spongepowered.api.event.EventContext;
import org.spongepowered.api.event.EventContextKeys;
import org.spongepowered.api.Sponge;

    // Mutation code
}

Boş olmayan bir neden vermeniz gerektiğini unutmayın. Etkinliğiniz İptal Edilebilir ise, olay tarafından açıklanan işlemi gerçekleştirmeden önce iptal edilmediğinden emin olun.
