This would result in + main thread chunk loads when they weren't really necessary, especially + on low view distances or "slow" async chunk loads after teleports or + other prioritisation. + + This changes it to only try to render already loaded chunks based on + the assumption that the chunks around the player will get loaded + eventually anyways and that maps will get checked for update every + five ticks that movement occur in anyways. + +diff --git a/src/main/java/net/minecraft/world/item/MapItem.java b/src/main/java/net/minecraft/world/item/MapItem.java +index 339dfd9fdffbc1c49b9112ba43ef6f05d85bdf86..44bfc5560a1b43925aabfd8137495e169da32fa2 100644 +--- a/src/main/java/net/minecraft/world/item/MapItem.java ++++ b/src/main/java/net/minecraft/world/item/MapItem.java +@@ -131,9 +131,9 @@ public class MapItem extends ComplexItem { + int k2 = (j / i + k1 - 64) * i; + int l2 = (k / i + l1 - 64) * i; + Multiset<MaterialColor> multiset = LinkedHashMultiset.create(); +- LevelChunk chunk = world.getChunkAt(new BlockPos(k2, 0, l2)); ++ LevelChunk chunk = world.getChunkIfLoaded(new BlockPos(k2, 0, l2)); // Paper - Maps shouldn't load chunks + +- if (!chunk.isEmpty()) { ++ if (chunk != null && !chunk.isEmpty()) { // Paper - Maps shouldn't load chunks + ChunkPos chunkcoordintpair = chunk.getPos(); + int i3 = k2 & 15; + int j3 = l2 & 15; |
