From a0d1cba8b421d1536b09fb97f3e089d64aeb3c26 Mon Sep 17 00:00:00 2001 From: Aikar Date: Fri, 29 Apr 2016 20:02:00 -0400 Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes Maps used a modified version of rendering to support plugin controlled imaging on maps. The Craft Map Renderer is much slower than Vanilla, causing maps in item frames to cause a noticeable hit on server performance. This updates the map system to not use the Craft system if we detect that no custom renderers are in use, defaulting to the much simpler Vanilla system. Additionally, numerous issues to player position tracking on maps has been fixed. diff --git a/src/main/java/net/minecraft/server/EntityHuman.java b/src/main/java/net/minecraft/server/EntityHuman.java index 1a41a9c1d9..1a1b1dd1e8 100644 --- a/src/main/java/net/minecraft/server/EntityHuman.java +++ b/src/main/java/net/minecraft/server/EntityHuman.java @@ -590,6 +590,12 @@ public abstract class EntityHuman extends EntityLiving { return null; } // CraftBukkit end + // Paper start - remove player from map on drop + if (itemstack.getItem() == Items.FILLED_MAP) { + WorldMap worldmap = ItemWorldMap.getSavedMap(itemstack, this.world); + worldmap.updateSeenPlayers(this, itemstack); + } + // Paper end return entityitem; } diff --git a/src/main/java/net/minecraft/server/WorldMap.java b/src/main/java/net/minecraft/server/WorldMap.java index fc08158937..090d3dbd31 100644 --- a/src/main/java/net/minecraft/server/WorldMap.java +++ b/src/main/java/net/minecraft/server/WorldMap.java @@ -31,6 +31,7 @@ public class WorldMap extends PersistentBase { private final Map l = Maps.newHashMap(); public final Map decorations = Maps.newLinkedHashMap(); private final Map m = Maps.newHashMap(); + private org.bukkit.craftbukkit.map.RenderData vanillaRender = new org.bukkit.craftbukkit.map.RenderData(); // Paper // CraftBukkit start public final CraftMapView mapView; @@ -43,6 +44,7 @@ public class WorldMap extends PersistentBase { // CraftBukkit start mapView = new CraftMapView(this); server = (CraftServer) org.bukkit.Bukkit.getServer(); + vanillaRender.buffer = colors; // Paper // CraftBukkit end } @@ -115,6 +117,7 @@ public class WorldMap extends PersistentBase { this.l.put(mapiconbanner.f(), mapiconbanner); this.a(mapiconbanner.c(), (GeneratorAccess) null, mapiconbanner.f(), (double) mapiconbanner.a().getX(), (double) mapiconbanner.a().getZ(), 180.0D, mapiconbanner.d()); } + vanillaRender.buffer = colors; // Paper NBTTagList nbttaglist1 = nbttagcompound.getList("frames", 10); @@ -190,6 +193,7 @@ public class WorldMap extends PersistentBase { this.b(); } + public void updateSeenPlayers(EntityHuman entityhuman, ItemStack itemstack) { this.a(entityhuman, itemstack); } // Paper - OBFHELPER public void a(EntityHuman entityhuman, ItemStack itemstack) { if (!this.humans.containsKey(entityhuman)) { WorldMap.WorldMapHumanTracker worldmap_worldmaphumantracker = new WorldMap.WorldMapHumanTracker(entityhuman); @@ -425,6 +429,21 @@ public class WorldMap extends PersistentBase { public class WorldMapHumanTracker { + // Paper start + private void addSeenPlayers(java.util.Collection icons) { + org.bukkit.entity.Player player = (org.bukkit.entity.Player) trackee.getBukkitEntity(); + WorldMap.this.decorations.forEach((name, mapIcon) -> { + // If this cursor is for a player check visibility with vanish system + org.bukkit.entity.Player other = org.bukkit.Bukkit.getPlayerExact(name); // Spigot + if (other == null || player.canSee(other)) { + icons.add(mapIcon); + } + }); + } + private boolean shouldUseVanillaMap() { + return mapView.getRenderers().size() == 1 && mapView.getRenderers().get(0).getClass() == org.bukkit.craftbukkit.map.CraftMapRenderer.class; + } + // Paper end public final EntityHuman trackee; private boolean d = true; private int e; @@ -441,9 +460,12 @@ public class WorldMap extends PersistentBase { @Nullable public Packet a(ItemStack itemstack) { // CraftBukkit start - org.bukkit.craftbukkit.map.RenderData render = WorldMap.this.mapView.render((org.bukkit.craftbukkit.entity.CraftPlayer) this.trackee.getBukkitEntity()); // CraftBukkit + if (!this.d && this.i % 5 != 0) { this.i++; return null; } // Paper - this won't end up sending, so don't render it! + boolean vanillaMaps = shouldUseVanillaMap(); // Paper + org.bukkit.craftbukkit.map.RenderData render = !vanillaMaps ?
