    Old description (open)
    If you enjoy fighting monsters for glorious prizes or just the sheer thrill of battle, you and your friends can now join forces against hordes of Minecraft evils in the exciting gladiator-style survival mini-game MobArena!

    Heavily inspired by Deminetix' Fight-plugin, MobArena is a PvE-take on arena-gameplay, with a similar class-based system. Instead of fighting other players, you team up with them to beat oncoming waves of monsters, earning rewards in the process. MobArena can be played alone, or with as many friends as you like!

    • Fight oncoming waves of monsters
    • Play alone or team up with friends
    • Earn glorious prizes
    • Customizable classes, rewards and waves
    • Easy to set up
    • Extremely easy to use
    • Very few user commands
    • Supports Permissions and all major economies
    • Supports Spout
    • Supports Heroes
    Note: When you post a bug report, please provide a stacktrace/error from the server log/console window. Post this stacktrace in either a pastebin, a pastie, or a CODE-block! The same applies for config-files, permissions-files, etc! Please don't put them directly in your posts, as they become gigantic and annoying to read. If you don't follow this guideline, I might ignore your post!

    Wiki - Instructions, commands, FAQ, etc.
    I have set up a Wiki for MobArena. It contains a bunch of information and guides on how to set up and customize arenas, an overview of all the commands, how to set up Permissions, as well as frequently asked questions.

    New: MobArena now has its own IRC channel (#mobarena @ EsperNet). Click here for a web-based IRC client. Feel free to stop by to get help setting everything up if you really don't understand the Wiki and the instructional video, or to have a chat about MobArena (or anything else, for that matter) :)

    Getting started with MobArena, by Flamers
    Flamers made this really easy-to-follow, simple video of how to get started with MobArena. It covers installing the plugin, defining an arena region and setting up basic leaderboards, as well as a few pointers for arena design.

    To avoid wasting not only your own time, but mine as well, I expect everyone to do some extensive troubleshooting before posting bug reports. What does this mean?

    Try MobArena on a fresh server.
    MobArena works perfectly fine when I release it. Sure, there are a few bugs, but it works. If it doesn't work for you, something is most likely wrong on your end. Set up a local test-server, and verify that MobArena works before claiming that it doesn't. When you have verified that MobArena does indeed work, you can start adding other plugins and settings until something conflicts.

    Disable other plugins.
    The first thing you need to do is disable all other plugins. If you can't reproduce the bug with other plugins disabled, you know that you have a conflicting plugin. Now perform a binary search on the other plugins, or if you don't know how to do that, just add a couple of plugins back to the plugins-folder, try to reproduce the bug, and if you can't, the conflicting plugin must be in the remaining set of plugins.

    Write down reproduction steps.
    Figure out the exact steps to reproduce/trigger the bug. I need precise steps, and as much information as possible, because there are often many things that could be going on. An example of reproduction steps could be:
    1. Type /ma join
    2. Punch the Archer class sign
    3. Wait for someone else to join
    4. Punch the iron block
    5. Type /ma leave before the other player picks a class

    Check the console window/server.log
    Make sure you check the server.log file for any MobArena errors or exceptions. If you find any, copy the ENTIRE exception (including all the lines that say "at com.garbagemule.MobArena...") and paste it (with the other information) in a CODE-tag here in the thread.

    I develop MobArena for the fun of it and the positive feedback is all it takes to make me happy, but a few people have asked for a link, so if you're one of them, here's a link: Donate - You can donate as much as you want, even down to a few cents! If I get enough donations, I will spend the money on an extra Minecraft account to aid me in developing/testing/debugging MobArena :)


    • Updated for CB 1337.
    • The repair-delay node is now unused! The reason for this is that it is now possible (with the release of 1317) to cancel block damage in explosions, and still retain the animation and sound! This also means that arenas should be fully pistons-compatible (for arenas that don't use soft-restore or force-restore)! I'm hoping to see some screenshots and videos of shifting arenas! :)
    • You can now right-click signs in the lobby! I finally found a super easy solution to the improperly updating inventory issue with right-clicking class signs. The result is that players can now left- or right-click as they please. This should solve all issues related to players not being able to choose classes, due to spawn region and WorldGuard/Factions/whatever conflicts.
    • It is no longer possible to warp out of the lobby.
    • New per-arena setting: final-wave - Allows for setting a final wave, meaning on that wave, the arena will end, regardless of how many players are alive.
    Version (open)

    • v0.94.3.11 - Updated Register, built against CB 1240.
    • v0.94.3.8 - Added basic leaderboards.
    • v0.94.3.6 - Fixed MagicSpells support - MobArena no longer supports MagicSpells pre-v1.1!
    • v0.94.3.5 - Fixed a bunch of bugs introduced with CB 1185, as well as a couple of minor MobArena bugs.
    • Updated for CraftBukkit #1185
    • Updated economy support (now supports iConomy 6).
    • Added the three new mob types, Enderman/Endermen, CaveSpider/CaveSpiders, Silverfish. They can be used just like the other mob types in the waves.
    • Endermen cannot pick up arena blocks (this is why).
    • Endermen cannot place blocks in arena regions.
    • The per-class permission syntax has been fixed and changed slightly. The Wiki has been updated (clicky).
    • Fixed MagicSpells issues.
    Version 0.94.2 (open)

    • Redstone circuits now work properly in arenas.
    • Lightning now properly strikes on spawnpoints on special waves.
    • Fixed an issue where players somehow warping/cheating out of the arena world get kicked from the server when discovered.
    • Added MagicSpells support. Use the magicspells.yml file to ban certain spells from the arena either for the whole session, or only during boss waves.
    • Fixed the Heroes death conflict. MobArena and Heroes should now play nice together. Further Heroes support is planned for upcoming releases.
    • [COLOR=#1000000]MobArena will no longer support the discontinued Permissions 2.x and 3.x permission systems.[/COLOR] Recommended permissions systems include PermissionsBukkit (defacto standard) or PermissionsEX.
    Version 0.94.1 (open)

    • Added two new boss abilities: 'shuffle-positions' and 'flood'. Try them out!
    • Players disconnecting/crashing during an arena session no longer get corrupted data files due to economy rewards.
    • Weapon durability is now correctly set to "unlimited".
    • Item sub-types (cocoa beans, bonemeal, colored wool, etc.) now work again.
    • Players can no longer join the arena without first picking a class.
    • MobArena now works with spawn-monsters=false again.
    Version 0.94 (open)

    • Completely revamped the waves system! Undeniably the biggest feature in MobArena since multiple arenas in v0.92, the new customizable waves are guaranteed to bring much more awesomeness to your MobArenas. The waves system brings two new wave types, swarm waves and boss waves. The latter is a very elaborate feature, and the whole waves system has been given its own page on the Wiki. Note: MobArena will ignore all old wave settings, but use sane defaults.
    • Revamped the logging system. Instead of logging: true, you can now use logging: yml/xml. The logging system will now keep track of the last session only, but also maintain a collection of 'totals' for each arena. The idea behind these easy-to-parse files is making the stats available on server web pages.
    • Added SuperPerms/PermissionsBukkit support. Note that specifying mobarena.arenas.* and mobarena.classes.* probably won't work, but these nodes are given to everyone by default.
    • Added Spout support. Currently, the only Spouty thing MobArena does is print (some) announcements as notifications/achievements. This should limit the amount of "chat spam" that MobArena produces. Other Spout-features are planned, but don't expect something crazy. Note that MobArena does NOT require Spout!
    • Monsters will no longer target pet wolves. This is a major nerf to pet classes, but they were very overpowered as it was.
    • Fixed item amounts greater than 64 sometimes bugging out. You should now be able to put arrow:1024 for your Archer classes :)
    • Fixed players losing their stored items and/or earned rewards upon disconnecting from the arena.
    • Fixed blocks not restoring when burned by fire.
    • Fixed an issue with entry fees. They should no longer cause any problems.
    • Fixed slimes. That's right! Slimes that spawn as a result of bigger slimes splitting upon death are now considered arena monsters. This also means that Slimes no longer drop slime balls; as intended.
    • Revamped the repairing algorithm. It is now MUCH more sophisticated, and is capable of repairing not only signs and containers, but also torches, doors and beds. Redstone -should- repair properly as well, but it is still slightly buggy.
    • Added support for restorable containers. Registered chests, dispensers, and furnaces will have their contents stored upon arena start, and restored at arena end. This is useful for providing the arena players with chests with e.g. upgrades or food.
    • Added new commands (for the feature above) - /ma addcontainer <name>, /ma delcontainer <name>, /ma containers. These commands work much like the the spawnpoint commands. To add a container, simply look at the container and type /ma addcontainer <name>.

    I enjoyed your plugin, now I had to remove it due to problems, don't get me wrong a completely understand, but I have a life and work full time as well, yet here am replying.

    It takes a lot less time to reply to a post than it does to write and maintain a plugin :) I will be back to working on MobArena in a few days, incorporating all of ACStache's fixes and getting into fixing more bugs.

    Is it somehow possible to add a class only for a special group (like donators)? If there isn`t, can we expect it somewhere in the future? And also, what about giving player enchanted items?

    hmm... I've not seen this error before. Could you post your config on pastebin please?

    this is a known issue in, try updating to found here. make sure to delete the old .jar when adding this one, as it's not initially named the same thing

    same link I gave to dabram71 just above, it's the current "unofficial" fix since garbagemule was off being busy getting smart and all :D
    the changing arena region was also a bug that has since been fixed I'm pretty sure, but that was before I started making fixes. let us know if that doesn't fix the issue.

    What exactly were you typing for the setclass command, and what exactly did you have in your inventory/armor slots?

    hmm... I've seen this a couple of times, but I'm not sure why that's happening. The code that this is breaking on is "spawnCreature(World, EntityType)" and it's saying EntityType isn't a LivingEntity. But the code doesn't require a LivingEntity, just an EntityType.

    Well its good to know someone is still keeping up on the development. ill do some more tests to see what might cause the bug to keep occuring. am also pretty sure that i have the latest dev version (is there any way to check?).

    the bug always seems to occur when i make a new arena, and it only extends the region of the first arena i made, making it reach out all the way to the new arena i created

    also, is it possible to edit the base stats of a class, like base health, base speed, base jump height, stuff like that. because that would give a lot more flexibility to class creation, like having a tank thats actually slow
  13. Offline


    as of right now, class stats are default across the board, and it's not possible to change it (unless you have some other plugin that can allow that, and you provide per-MA class permissions.

    To check your version of MobArena, either check the top line of your config or type "version MobArena" into your server console, or "/version MobArena" while logged onto your server. Unfortunately, there are many terms out there that all describe a non recommended build (dev, latest, bleeding, unofficial). Regardless of the term, the version number is key when you talk about your particular version. The "current" or "latest" can always be found in the topic of the IRC Chat Channel (linked in the main post) and will typically say what version number it is

    Few Things:
    MagicSpells compatibility seems to be broken

    The config yml that lets us restrict spells on boss waves does not seem to block the spells
    Projectile spells that use enderpearls as the projectile from MagicSpells also teleport the player to where it is thrown (magicspells blocks it from doing it outside of Mob Arena)

    Also the annoying bug where the boss glitches and becomes invisible seems to happen a lot :x

    Hey i se the video have been delete from youtube! please add this video to the forums

    I tried the setclass commands for all the available default classes: knight, tank etc. At the time I don't believe I had anything in my posession but a diamond sword.
  17. Offline


    so this ended up being an issue with the deprecation of the method used to spawn monsters on the newer builds (R4.1) of CB. It has been fixed with the latest build, 2249

    that still doesn't show me the exact syntax of the command, please figure out exactly what you typed, and try to reproduce the error, and record how you do it.

    Its ok. I solved the problem, thanks anyway.

    Hey guys i made a mob arena server! ip is mobarena.g.nfoservers.com you can also submit your own arenas/bosses
  21. Offline


    for enchanted items you'll have to go in the config file and remove the spaces between all the enchantments. Like this
    when you add a class you'll have this:
    diamond_sword 17:2; 19:1; 20:1, cooked_beef:4
    and you have to make it:
    diamond_sword 17:2;19:1;20:1, cooked_beef:4
    (for the enchantment numbers and effects go to the wiki and look at the number in front of each enchantment)

    There still seems to be an issue with the boundries of arenas spazing out. in my example, whenever i make an arena (using the command) or edit the config file, the boundries of one of my arenas stretches all the way accross the map to the newest arena built

    That error is from MobArena trying to set up some leaderboards, and not finding the signs that you set up. stop your server, delete the "leaderboard:" line from your MobArena config.yml under the coords section, and start your server back up. As far as I'm aware, leaderboards have to be in the same world as the arena itself, so keep that in mind.

    are you making sure to select the new arena before doing any set up commands? "/ma setarena newarena"
    did you also make sure to update to to fix the auto-expanding bugs?

    it's probably located in the part of your log where your server starts up.
    do this:
    1. stop your server
    2. delete your server.log file
    3. start your server
    4. stop your server
    5. copy the entire contents of your new server.log file into a pastebin link
    6. provide the link here
    download, found here

    that error only happens when you are outside of the arena region when a new wave spawns. I'd like you to do 2 things for me.
    1. using pastebin, provide us your MobArena config file
    2. update to which I just linked above
    3. after updating, whenever someone gets kicked, check your console and record where MobArena says they were and compare it to your Arena coordinates

    @ ACstache

    if your talking about the update you released on july 2nd, yes im updated (maybe i updated wrong though, i just copied the jar over the old one)

    also just wondering, will this plugin be compatible with 1.3 when it comes out?

    Amazing plugin, its a very fun thing to do when things on your server start to slow down at night.

    Just one little issue im having with it. People are using it to Grind Exp for "McMMO" do you think you could talk to the Author of McMMO and ask him if you can disabled it in the region of the MobArena?

    How do you make a supply wave? Ya know, where monsters drop items to help the players. I can't find a tutorial anywhere! I know they exist, as I've seen them on servers. HALP MEH.

    Um, i dont know if this is in the plugin, but how do you get the classes from signs and when you punch the iron block it teles you into arena, would love to know, thanks =D
