Hi there! I've been sitting here for 30 minutes trying to figure out why Code (Text): format.getWriter(new FileOutputStream(schemFile)).write(clipboard); is null. Here's my code: Code (Text): public void savePreviousArea(Location loc, int counter) { World w = ConfigManager.getWorld(); com.sk89q.worldedit.world.World weWorld = new BukkitWorld(w); Location startLoc = loc; startLoc.setZ((startLoc.getZ() - 4)); startLoc.setX((startLoc.getX() - 5)); //4 blocks back //5 blocks left' //Select 2 //7 blocks forward //6 blocks right //6 blocks up WorldEditPlugin worldEdit = (WorldEditPlugin) Bukkit.getServer().getPluginManager().getPlugin("WorldEdit"); Location s1Loc = new Location(w, (startLoc.getX() - 5), startLoc.getY(), (startLoc.getZ() + 4)); Location s2Loc = new Location(w, (startLoc.getX() + 6), (startLoc.getY() + 6), (startLoc.getZ() - 7)); CuboidRegion region = new CuboidRegion(BlockVector3.at(s1Loc.getX(), s1Loc.getY(), s1Loc.getZ()), BlockVector3.at(s2Loc.getX(), s2Loc.getY(), s2Loc.getZ())); File restoresFolder = new File(this.getDataFolder(), "restores"); File schemFile = new File(restoresFolder, "restore" + counter + ".schem"); if(!restoresFolder.exists()) { makeRestoreFolder(restoresFolder); } if(!schemFile.exists()) { makeRestoreFile(schemFile); } try { BlockArrayClipboard clipboard = new BlockArrayClipboard(region); Extent source = WorldEdit.getInstance().getEditSessionFactory().getEditSession(new BukkitWorld(w), 99999); Extent destination = source; ForwardExtentCopy copy = new ForwardExtentCopy(source, region, clipboard.getOrigin(), destination, BlockVector3.at(s1Loc.getX(), s1Loc.getY(), s1Loc.getZ())); copy.setSourceMask(new ExistingBlockMask(source)); Operations.completeLegacy(copy); ClipboardFormat format = ClipboardFormats.findByFile(schemFile); format.getWriter(new FileOutputStream(schemFile)).write(clipboard); }catch(IOException | MaxChangedBlocksException e) { e.printStackTrace(); } } Error: Code (Text): [18:42:06] [Server thread/ERROR]: Error occurred while enabling RandomTreasure v1.0 (Is it up to date?) java.lang.NullPointerException: null at me.caleb.RandomTreasure.Main.savePreviousArea(Main.java:198) ~[?:?] at me.caleb.RandomTreasure.Main.generateStructures(Main.java:94) ~[?:?] at me.caleb.RandomTreasure.Main.onEnable(Main.java:50) ~[?:?] at org.bukkit.plugin.java.JavaPlugin.setEnabled(JavaPlugin.java:263) ~[spigot.jar:git-Spigot-56f8471-6567017] at org.bukkit.plugin.java.JavaPluginLoader.enablePlugin(JavaPluginLoader.java:352) ~[spigot.jar:git-Spigot-56f8471-6567017] at org.bukkit.plugin.SimplePluginManager.enablePlugin(SimplePluginManager.java:417) ~[spigot.jar:git-Spigot-56f8471-6567017] at com.rylinaux.plugman.util.PluginUtil.load(PluginUtil.java:366) ~[?:?] at com.rylinaux.plugman.util.PluginUtil.load(PluginUtil.java:318) ~[?:?] at com.rylinaux.plugman.util.PluginUtil.reload(PluginUtil.java:380) ~[?:?] at com.rylinaux.plugman.command.ReloadCommand.execute(ReloadCommand.java:122) ~[?:?] at com.rylinaux.plugman.PlugManCommandHandler.onCommand(PlugManCommandHandler.java:95) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:45) ~[spigot.jar:git-Spigot-56f8471-6567017] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:149) ~[spigot.jar:git-Spigot-56f8471-6567017] at org.bukkit.craftbukkit.v1_14_R1.CraftServer.dispatchCommand(CraftServer.java:710) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.PlayerConnection.handleCommand(PlayerConnection.java:1641) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.PlayerConnection.a(PlayerConnection.java:1481) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.PacketPlayInChat.a(PacketPlayInChat.java:47) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.PacketPlayInChat.a(PacketPlayInChat.java:1) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.PlayerConnectionUtils.lambda$0(PlayerConnectionUtils.java:19) ~[spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.TickTask.run(SourceFile:18) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.IAsyncTaskHandler.executeTask(SourceFile:144) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.IAsyncTaskHandlerReentrant.executeTask(SourceFile:23) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.IAsyncTaskHandler.executeNext(SourceFile:118) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.MinecraftServer.aX(MinecraftServer.java:909) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.MinecraftServer.executeNext(MinecraftServer.java:902) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.IAsyncTaskHandler.awaitTasks(SourceFile:127) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.MinecraftServer.sleepForTick(MinecraftServer.java:886) [spigot.jar:git-Spigot-56f8471-6567017] at net.minecraft.server.v1_14_R1.MinecraftServer.run(MinecraftServer.java:819) [spigot.jar:git-Spigot-56f8471-6567017] at java.lang.Thread.run(Unknown Source) [?:1.8.0_231] What i'm doing: Writing to a schematic file
I don't remember what the solution was, but i can link you to my GitHub and perhaps you could see what I did.
