From 0000000000000000000000000000000000000000 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 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/BaseBlockPosition.java b/src/main/java/net/minecraft/core/BaseBlockPosition.java index 25fdd55a7548cfaa45a541ad77f22f33c33e7471..4b56683336fdab06804efdc8ca1f7c130b77291f 100644 --- a/src/main/java/net/minecraft/core/BaseBlockPosition.java +++ b/src/main/java/net/minecraft/core/BaseBlockPosition.java @@ -22,6 +22,15 @@ public class BaseBlockPosition implements Comparable { private int b;public final void setY(final int y) { this.b = y;
