From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 3 Mar 2016 02:07:55 -0600 Subject: [PATCH] Optimize isInWorldBounds and getBlockState for inlining 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/core/Vec3i.java b/src/main/java/net/minecraft/core/Vec3i.java index 0000000000000000000000000000000000000000..0000000000000000000000000000000000000000 100644 --- a/src/main/java/net/minecraft/core/Vec3i.java +++ b/src/main/java/net/minecraft/core/Vec3i.java @@ -0,0 +0,0 @@ public class Vec3i implements Comparable { });
