From 80c13ed0dab738b2741d02291129c231a6e415a6 Mon Sep 17 00:00:00 2001 From: Aikar Date: Tue, 19 Dec 2017 16:28:32 -0500 Subject: [PATCH] ExperienceOrbs API for Reason/Source/Triggering player Adds lots of information about why this orb exists. Replaces isFromBottle() with logic that persists entity reloads too. diff --git a/src/main/java/org/bukkit/entity/ExperienceOrb.java b/src/main/java/org/bukkit/entity/ExperienceOrb.java index c286edfd..f847543b 100644 --- a/src/main/java/org/bukkit/entity/ExperienceOrb.java +++ b/src/main/java/org/bukkit/entity/ExperienceOrb.java @@ -1,5 +1,7 @@ package org.bukkit.entity; +import javax.annotation.Nullable; + /** * Represents an Experience Orb. */ @@ -18,4 +20,94 @@ public interface ExperienceOrb extends Entity { * @param value Amount of experience */ public void setExperience(int value); + + // Paper start + /** + * Check if this orb was spawned from a {@link ThrownExpBottle} + * + * @return if orb was spawned from a bottle + * @deprecated Use getSpawnReason() == EXP_BOTTLE + */ + @Deprecated + default boolean isFromBottle() { + return getSpawnReason() == SpawnReason.EXP_BOTTLE; + } + + /** + * Reasons for why this Experience Orb was spawned + */ + enum SpawnReason { + /** + * Spawned by a player dying + */ + PLAYER_DEATH, + /** + * Spawned by an entity dying after being damaged by a player + */ + ENTITY_DEATH, + /** + * Spawned by player using a furnace + */ + FURNACE, + /** + * Spawned by player breeding animals + */ + BREED, + /** + * Spawned by player trading with a villager + */ + VILLAGER_TRADE, + /** + * Spawned by player fishing + */ + FISHING, + /** + * Spawned by player breaking a block that gives experience points such as Diamond Ore + */ + BLOCK_BREAK, + /** + * Spawned by Bukkit API + */ + CUSTOM, + /** + * Spawned by a player throwing an experience points bottle + */ + EXP_BOTTLE, + /** + * We do not know why it was spawned + */ + UNKNOWN + } + + /** + * If this experience orb was triggered to be spawned by + * an entity such as a player, due to events such as killing entity, + * breaking blocks, smelting in a furnace, etc, this will return the UUID + * of the entity that triggered this orb to drop. + * + * In the case of an entity being killed, this will be the killers UUID. + * + * @return UUID of the player that triggered this orb to drop, or null if unknown/no triggering entity + */ + @Nullable java.util.UUID getTriggerEntityId(); + + /** + * If this experience orb was spawned in relation to another + * entity, such as a player or other living entity death, or breeding, + * return the source entity UUID. + * + * In the case of breeding, this will be the new baby entities UUID. + * In the case of an entity being killed, this will be the dead entities UUID. + * + * @return The UUID of the entity that sourced this experience orb + */ + @Nullable java.util.UUID getSourceEntityId(); + + /** + * Gets the reason that this experience orb was spawned.
