From 0c5d5c8f8863549c7b36e7d557a76889765f5961 Mon Sep 17 00:00:00 2001 From: md_5 Date: Sat, 23 Mar 2013 19:08:41 +1100 Subject: [PATCH] Limit Custom Map Rendering The default CraftBukkit render sequence for maps is ridiculously slow. By only using it when a custom renderer has been added (rarely in most cases), we can fallback to the Vanilla renderer for general usage. This leads to a much higher effiency overall, especially if no plugins are rendering such maps. diff --git a/src/main/java/net/minecraft/server/WorldMapHumanTracker.java b/src/main/java/net/minecraft/server/WorldMapHumanTracker.java index bf3e6fe..305dceb 100644 --- a/src/main/java/net/minecraft/server/WorldMapHumanTracker.java +++ b/src/main/java/net/minecraft/server/WorldMapHumanTracker.java @@ -41,23 +41,29 @@ public class WorldMapHumanTracker { int i; int j; - org.bukkit.craftbukkit.map.RenderData render = this.worldMap.mapView.render((org.bukkit.craftbukkit.entity.CraftPlayer) trackee.getBukkitEntity()); // CraftBukkit + // Spigot start + boolean custom = this.worldMap.mapView.renderers.size() > 1 || !(this.worldMap.mapView.renderers.get(0) instanceof org.bukkit.craftbukkit.map.CraftMapRenderer); + org.bukkit.craftbukkit.map.RenderData render = (custom) ? this.worldMap.mapView.render((org.bukkit.craftbukkit.entity.CraftPlayer) trackee.getBukkitEntity()) : null; // CraftBukkit if (--this.g < 0) { this.g = 4; - abyte = new byte[render.cursors.size() * 3 + 1]; // CraftBukkit + abyte = new byte[((custom) ? render.cursors.size() : this.worldMap.g.size()) * 3 + 1]; // CraftBukkit abyte[0] = 1; i = 0; // CraftBukkit start - for (i = 0; i < render.cursors.size(); ++i) { - org.bukkit.map.MapCursor cursor = render.cursors.get(i); - if (!cursor.isVisible()) continue; - abyte[i * 3 + 1] = (byte) (cursor.getRawType() << 4 | cursor.getDirection() & 15); - abyte[i * 3 + 2] = (byte) cursor.getX(); - abyte[i * 3 + 3] = (byte) cursor.getY(); + // Spigot start + for (Iterator iterator = ((custom) ? render.cursors.iterator() : this.worldMap.g.values().iterator()); iterator.hasNext(); ++i) { + org.bukkit.map.MapCursor cursor = (custom) ?
