Hello, I am trying to create multiple spawn points for my mini-game plugin but I am having an issue when trying to add a spawn point then saving it to the "arenas.yml" file. Command Code (Text): arena.addSpawn(user.getPlayer().getLocation()); user.sendMessage(getPlugin().getStrings().getPrefix() + "&aSpawn point added for Arena ID: " + getPlugin().getArenaManager().getNumOfArenas()); Arena#addSpawn Method (By the way: the first 2 lines in the addSpawn method work correctly. The issue is coming when I try writing to the file) Code (Text): public void addSpawn(Location location) { this.getSpawns().add(location); this.setNumOfSpawns(this.getNumOfSpawns() + 1); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".NumOfSpawns", this.plugin.arenasConfig.getInt("Arenas." + this.getId() + ".NumOfSpawns") + 1); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".World", location.getWorld().getName()); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".X", location.getX()); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".Y", location.getY()); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".Z", location.getZ()); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".Yaw", location.getYaw()); this.plugin.arenasConfig.set("Arenas." + this.getId() + ".Spawns." + this.getNumOfSpawns() + ".Pitch", location.getPitch()); this.plugin.saveArenasFile(); } Error in Console Code (Text): [17:04:10] [Server thread/INFO]: Rega issued server command: /oitc addspawn 1 [17:04:10] [Server thread/ERROR]: null org.bukkit.command.CommandException: Unhandled exception executing command 'oitc' in plugin ????Oitc v1.0.6-BETA at org.bukkit.command.PluginCommand.execute(PluginCommand.java:46) ~[spigot.jar:git-Spigot-c5146ba-01930e2] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:141) ~[spigot.jar:git-Spigot-c5146ba-01930e2] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.dispatchCommand(CraftServer.java:646) ~[spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.PlayerConnection.handleCommand(PlayerConnection.java:1135) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.PlayerConnection.a(PlayerConnection.java:970) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:45) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.PacketPlayInChat.a(PacketPlayInChat.java:1) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.PlayerConnectionUtils$1.run(SourceFile:13) [spigot.jar:git-Spigot-c5146ba-01930e2] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [?:1.8.0_45] at java.util.concurrent.FutureTask.run(Unknown Source) [?:1.8.0_45] at net.minecraft.server.v1_8_R3.SystemUtils.a(SourceFile:60) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.MinecraftServer.B(MinecraftServer.java:718) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.DedicatedServer.B(DedicatedServer.java:367) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.MinecraftServer.A(MinecraftServer.java:657) [spigot.jar:git-Spigot-c5146ba-01930e2] at net.minecraft.server.v1_8_R3.MinecraftServer.run(MinecraftServer.java:560) [spigot.jar:git-Spigot-c5146ba-01930e2] at java.lang.Thread.run(Unknown Source) [?:1.8.0_45] Caused by: java.lang.NullPointerException at com.REMOVED.oitc.games.arenas.Arena.addSpawn(Arena.java:56) ~[?:?] at com.REMOVED.oitc.commands.CommandOITC.onCommand(CommandOITC.java:152) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[spigot.jar:git-Spigot-c5146ba-01930e2] ... 15 more Line 56 Code (Text): this.plugin.arenasConfig.set("Arenas." + this.getId() + ".NumOfSpawns", this.plugin.arenasConfig.getInt("Arenas." + this.getId() + ".NumOfSpawns") + 1);
Oops, forgot to specify that. Code (Text): this.plugin.arenasConfig.set("Arenas." + this.getId() + ".NumOfSpawns", this.plugin.arenasConfig.getInt("Arenas." + this.getId() + ".NumOfSpawns") + 1);
This is my arenas.yml Code (Text): Arenas: '1': Lobby: World: world X: -468.56551973482806 Y: 4.0 Z: -288.33136441801497 Yaw: 208.19998 Pitch: 90.0 NumOfSpawns: 0 Spawns: [] EDIT: Just changed it so "Spawn" does not define as a list.
arenaConfig is set to the FileConfiguration for the arenas.yml (Which is confirmed to work) and this.getId() returns the Arena's ID as a Integer (Confirm works)
Have you tried setting the value BEFORE you try to write it? To see if maybe the issue is trying to get the value while in the writing method?
You need to set that equal to something. private Main plugin = Bukkit.getServer().getPluginManager().getPlugin("MyPluginName"); EDIT: Change Main to Plugin
Also... in your config, you have the number listed as '1' and not 1. does getInt worked on quoted numbers?
