The only logic that's ran inside the ServerEntity#sendChanges for maps +now is just updating dirty map/decoration data. + +When no bukkit renderers are added to the map, we also re-use the same packet for all players who are tracking it which avoids a lot of work. + +diff --git a/src/main/java/net/minecraft/server/level/ServerEntity.java b/src/main/java/net/minecraft/server/level/ServerEntity.java +index 196280f54e397c69d32bd4d1f6ae666efdd93773..8ef1c11969310f64d06c8421969d171b6c399ab6 100644 +--- a/src/main/java/net/minecraft/server/level/ServerEntity.java ++++ b/src/main/java/net/minecraft/server/level/ServerEntity.java +@@ -108,29 +108,42 @@ public class ServerEntity { + + Entity entity = this.entity; + +- if (!this.trackedPlayers.isEmpty() && entity instanceof ItemFrame) { // Paper - Only tick item frames if players can see it ++ if (!this.trackedPlayers.isEmpty() && entity instanceof ItemFrame frame && frame.cachedMapId != null) { // Paper - Only tick item frames if players can see it // Paper + ItemFrame entityitemframe = (ItemFrame) entity; + + if (true || this.tickCount % 10 == 0) { // CraftBukkit - Moved below, should always enter this block +- ItemStack itemstack = entityitemframe.getItem(); ++ //ItemStack itemstack = entityitemframe.getItem(); // Paper - skip redundant getItem + +- if (this.level.paperConfig().maps.itemFrameCursorUpdateInterval > 0 && this.tickCount % this.level.paperConfig().maps.itemFrameCursorUpdateInterval == 0 && itemstack.getItem() instanceof MapItem) { // CraftBukkit - Moved this.tickCounter % 10 logic here so item frames do not enter the other blocks // Paper - Make item frame map cursor update interval configurable ++ if (this.level.paperConfig().maps.itemFrameCursorUpdateInterval > 0 && this.tickCount % this.level.paperConfig().maps.itemFrameCursorUpdateInterval == 0 /*&& itemstack.getItem() instanceof MapItem*/) { // CraftBukkit - Moved this.tickCounter % 10 logic here so item frames do not enter the other blocks // Paper - Make item frame map cursor update interval configurable // Paper - skip redundant getItem + Integer integer = entityitemframe.cachedMapId; // Paper + MapItemSavedData worldmap = MapItem.getSavedData(integer, this.level); + + if (worldmap != null) { ++ // Paper start - re-use the same update packet when possible ++ if (!worldmap.hasContextualRenderer) { ++ // Pass in a "random" player when a non-contextual plugin renderer is added to make sure its called ++ final Packet updatePacket = worldmap.framedUpdatePacket(integer, worldmap.hasPluginRenderer ?
