From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Tue, 30 May 2023 12:59:10 -0700 Subject: [PATCH] Refresh ProjectileSource for projectiles Makes sure the value returned by Projectile#getShooter in the API matches the owner UUID specified in the entity nbt. Previously, after the entity reloaded, Projectile#getShooter would return null, while the entity still had an owner. diff --git a/src/main/java/net/minecraft/world/entity/Entity.java b/src/main/java/net/minecraft/world/entity/Entity.java index 64068958a29f5e867932d6c23ab504a2fafdd3f1..b38c4cbcf0405d82c7b6e018e80a3174e460c1a4 100644 --- a/src/main/java/net/minecraft/world/entity/Entity.java +++ b/src/main/java/net/minecraft/world/entity/Entity.java @@ -382,6 +382,7 @@ public abstract class Entity implements Nameable, EntityAccess, CommandSource { public boolean valid; public boolean generation; public int maxAirTicks = this.getDefaultMaxAirSupply(); // CraftBukkit - SPIGOT-6907: re-implement LivingEntity#setMaximumAir() + @Nullable // Paper public org.bukkit.projectiles.ProjectileSource projectileSource; // For projectiles only public boolean lastDamageCancelled; // SPIGOT-5339, SPIGOT-6252, SPIGOT-6777: Keep track if the event was canceled public boolean persistentInvisibility = false; diff --git a/src/main/java/net/minecraft/world/entity/projectile/Projectile.java b/src/main/java/net/minecraft/world/entity/projectile/Projectile.java index 6d7ac0c8c171834fa8da94f158258a4774d80ec4..1b7cf6d06bdf36f146656727511a461f2520762e 100644 --- a/src/main/java/net/minecraft/world/entity/projectile/Projectile.java +++ b/src/main/java/net/minecraft/world/entity/projectile/Projectile.java @@ -49,14 +49,24 @@ public abstract class Projectile extends Entity implements TraceableEntity { this.ownerUUID = entity.getUUID(); this.cachedOwner = entity; } - this.projectileSource = (entity != null && entity.getBukkitEntity() instanceof ProjectileSource) ?
