From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Spottedleaf Date: Mon, 6 Apr 2020 17:53:29 -0700 Subject: [PATCH] Remove streams from Mob AI System The streams hurt performance and allocate tons of garbage, so replace them with the standard iterator. Also optimise the stream.anyMatch statement to move to a bitset where we can replace the call with a single bitwise operation. diff --git a/src/main/java/net/minecraft/world/entity/ai/goal/Goal.java b/src/main/java/net/minecraft/world/entity/ai/goal/Goal.java index d92ddc8a4c0f5249b7ff4f97af1ea3db413b2983..8c2ec30a35e86f2b30863045b586a67e485c624b 100644 --- a/src/main/java/net/minecraft/world/entity/ai/goal/Goal.java +++ b/src/main/java/net/minecraft/world/entity/ai/goal/Goal.java @@ -3,7 +3,8 @@ package net.minecraft.world.entity.ai.goal; import java.util.EnumSet; public abstract class Goal { - private final EnumSet flags = EnumSet.noneOf(Goal.Flag.class); + private final EnumSet flags = EnumSet.noneOf(Goal.Flag.class); // Paper unused, but dummy to prevent plugins from crashing as hard.
