    • getBlockAt

      public int getBlockAt​(GeyserSession session, int x, int y, int z)
      Description copied from class: WorldManager
      Gets the Java block state at the specified location
      Specified by:
      getBlockAt in class WorldManager
      Parameters:
      session - the session
      x - the x coordinate to get the block at
      y - the y coordinate to get the block at
      z - the z coordinate to get the block at
      Returns:
      the block state at the specified location

    • getBlockAtAsync

      public CompletableFuture<Integer> getBlockAtAsync​(GeyserSession session, int x, int y, int z)
      Overrides:
      getBlockAtAsync in class WorldManager

    • getBlocksAt

      public int[] getBlocksAt​(GeyserSession session, org.geysermc.erosion.util.BlockPositionIterator iter)
      Overrides:
      getBlocksAt in class WorldManager

    • hasOwnChunkCache

      public boolean hasOwnChunkCache()
      Description copied from class: WorldManager
      Checks whether or not this world manager requires a separate chunk cache/has access to more block data than the chunk cache.

      Some world managers (e.g. Spigot) can provide access to block data outside of the chunk cache, and even with chunk caching disabled. This method provides a means to check if this manager has this capability.

      Specified by:
      hasOwnChunkCache in class WorldManager
      Returns:
      whether or not this world manager has access to more block data than the chunk cache

    • sendLecternData

      public void sendLecternData​(GeyserSession session, int x, int z, List<com.github.steveice10.mc.protocol.data.game.level.block.BlockEntityInfo> blockEntityInfos)
      Description copied from class: WorldManager
      WorldManager.sendLecternData(GeyserSession, int, int, int) but batched for chunks.
      Specified by:
      sendLecternData in class WorldManager
      x - chunk x
      z - chunk z
      blockEntityInfos - a list of coordinates (chunk local) to grab lecterns from.

    • sendLecternData

      public void sendLecternData​(GeyserSession session, int x, int y, int z)
      Description copied from class: WorldManager
      Sigh.
      So, on Java Edition, the lectern is an inventory. Java opens it and gets the contents of the book there. On Bedrock, the lectern contents are part of the block entity tag. Therefore, Bedrock expects to have the contents of the lectern ready and present in the world. If the contents are not there, it takes at least two clicks for the lectern to update the tag and then present itself.
      We solve this problem by querying all loaded lecterns, where possible, and sending their information in a block entity tag.

      Note that the lectern data may be sent asynchronously.

      Specified by:
      sendLecternData in class WorldManager
      Parameters:
      session - the session of the player
      x - the x coordinate of the lectern
      y - the y coordinate of the lectern
      z - the z coordinate of the lectern

      Specified by:
      shouldExpectLecternHandled in class WorldManager
      Returns:
      whether we should expect lectern data to update, or if we have to fall back on a workaround.
