From 5372e9c03d78bdb92741561ef1c5d2f63c8621f7 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 3 Mar 2016 02:07:55 -0600 Subject: [PATCH] Optimize isValidLocation, getType and getBlockData for inling Hot methods, so reduce # of instructions for the method. Move is valid location test to the BlockPosition class so that it can access local variables. Replace all calls to the new place to the unnecessary forward. Optimize getType and getBlockData to manually inline and optimize the calls diff --git a/src/main/java/net/minecraft/server/BaseBlockPosition.java b/src/main/java/net/minecraft/server/BaseBlockPosition.java index e2a7b4be2..58f8b4b72 100644 --- a/src/main/java/net/minecraft/server/BaseBlockPosition.java +++ b/src/main/java/net/minecraft/server/BaseBlockPosition.java @@ -10,6 +10,14 @@ public class BaseBlockPosition implements Comparable { private final int a;
