Error with MM Items / Mob Drops

Error with MM Items / Mob Drops

Summary

It seems that there is a bug concerning MythicMobs Items (so impacting custom mob drops). Every things that are concerning items is simply not working.

Steps to reproduce

I personaly used my items files which were working in 1.15 version and did /mm items give .

But I think you can simply create an item (even basic) and try to make a mob dropping it or trying to get it from MythicMobs give command.

Current behavior

In game, I got the message "An internal error occured while attempting to perform this command" and I get in console :

[13:50:28] [Server thread/INFO]: Damien0503 issued server command: /mm items give Damien0503 AgriBoots [13:50:28] [Server thread/ERROR]: null org.bukkit.command.CommandException: Unhandled exception executing command 'mm' in plugin MythicMobs v4.10.0-SNAPSHOT-SNAPSHOT at org.bukkit.command.PluginCommand.execute(PluginCommand.java:47) ~[patched_1.16.2.jar:git-Paper-141] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:159) ~[patched_1.16.2.jar:git-Paper-141] at org.bukkit.craftbukkit.v1_16_R2.CraftServer.dispatchCommand(CraftServer.java:800) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.PlayerConnection.handleCommand(PlayerConnection.java:1907) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.PlayerConnection.a(PlayerConnection.java:1718) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.PacketPlayInChat.a(PacketPlayInChat.java:47) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.PacketPlayInChat.a(PacketPlayInChat.java:5) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.PlayerConnectionUtils.lambda$ensureMainThread$1(PlayerConnectionUtils.java:23) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.TickTask.run(SourceFile:18) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.IAsyncTaskHandler.executeTask(IAsyncTaskHandler.java:136) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.IAsyncTaskHandlerReentrant.executeTask(SourceFile:23) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.IAsyncTaskHandler.executeNext(IAsyncTaskHandler.java:109) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.MinecraftServer.ba(MinecraftServer.java:1135) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.MinecraftServer.executeNext(MinecraftServer.java:1128) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.IAsyncTaskHandler.executeAll(IAsyncTaskHandler.java:95) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.MinecraftServer.a(MinecraftServer.java:1264) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.MinecraftServer.w(MinecraftServer.java:999) ~[patched_1.16.2.jar:git-Paper-141] at net.minecraft.server.v1_16_R2.MinecraftServer.lambda$a$0(MinecraftServer.java:177) ~[patched_1.16.2.jar:git-Paper-141] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_265] Caused by: java.lang.NullPointerException at io.lumine.xikage.mythicmobs.items.MythicItem.generateItemStack(MythicItem.java:439) ~[?:?] at io.lumine.xikage.mythicmobs.commands.items.GiveCommand.onCommand(GiveCommand.java:86) ~[?:?] at io.lumine.xikage.mythicmobs.utils.commands.Command.onCommand(Command.java:64) ~[?:?] at io.lumine.xikage.mythicmobs.utils.commands.Command.onCommand(Command.java:55) ~[?:?] at io.lumine.xikage.mythicmobs.utils.commands.Command.onCommand(Command.java:55) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:45) ~[patched_1.16.2.jar:git-Paper-141] ... 18 more

And if I try to kill a mob, nothing it dropped.

Intended correct behavior

Uh... items should be gave / dropped ? :D

    Im having the same error, IM using latest MMOitems and MM build on Paper 1.14.4 (bc I still got other plugins who need to be updated) the item drop is a core feature for my server, which I really need to make it work, I'd really like if they could priotize the item drops.

    Same issue here.

      In the provided logs, it's saying you're using a version of MM that isn't compatible with 1.16.2?

    Tried latest dev build, so I can approve, even default drop is not working (via /mm i get )

    Apologies, something seems to be broken with the build bot and it did not push the appropriate changes to the website. My local builds definitely have this fixed. Should have a resolution shortly.

    This issue should be fixed in the latest build. Please try it and reopen the issue if you encounter more problems!

    @ashijin Something still wrong, items can't be stacked with items dropped from prev. version Nothing changed in config https://youtu.be/-Vrph8iJ7Nc <--- demo what happend

    https://pastebin.ubuntu.com/p/mRmck5nRdG/ <--- item configuration

    Also new items cant be used as trade currency anymore (via Shopkeepers plugin) Item name, lore and NBT tags count is similar.

    Bogdan @Bodyash ·

    Screenshot_from_2020-08-31_04-01-14

    Using powerNBT plugin I've found the diff in display.Name NBT tag 2 similar items, first generated in MM 4.9.1 and second one in from 4.10 dev build

    I think now I should replace all my items.

  • Ashijin
    Ashijin @ashijin ·

    The change in NBT values is an unfortunate side-effect of the new 1.16 text formatting to support all the new colors

    I am still having this issue too.

    I create the following item in Items/items.yml:

    RedLeatherChestplate:
  Id: 298
  Data: 0
  Options:
    Color: 255,0,0

    And then here's the error I'm getting:

    This occurs for any and all items.

    I found the issue was because the latest free version of MM is not compatible with 1.16.4. I purchased the premium version and used the latest dev version which solved the problem.

    It may be useful to users to communicate which MM versions are compatible with which MC versions.
