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!


Features:

• 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.

Troubleshooting:
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.


Donations:
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


Changelog:

Version 0.94.3.24

• 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 0.94.3.11 (open) Version 0.94.3.11 (close)

• 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) Version 0.94.2 (close)

• 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) Version 0.94.1 (close)

• 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) Version 0.94 (close)

• 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>.

Changelog (continued)

 

@KrazyBonez - It looks like you're using v0.93, and not v0.93.1? If so, please update to v0.93.1, as the problem you're having should be fixed.

 

Minor issue I noticed: 'Hellhounds' dont stay on fire after they get wet the first time.

Did you see the video on last page? I since have updated since then, all tall trees due to abuse and a few patches of slowsand to make things intrusting. may make a patch or 2 of fire...

 

I've been getting TONS of errors with mob arena installed. This is one of them.

2011-07-17 19:32:06 [INFO] [MobArena] ERROR! Could not restore inventory for Oiram988

 

@Delois - Whoa! That is one badass arena! I really, really love what you've done with the whole thing. The fact that it is so huge makes me so happy I changed the spawn algorithm to only spawn monsters near players The spectator area is amazing! It might be a little crowded to really see everything going on, but I think the top-down approach from such a high point is a really good idea! Very nice video; adding it to the list

@bothersome - Looks like there are some problems with inventory storing. Perhaps your server is a little too strict with file permissions? Try setting require-empty-inv-join: true.

 

Well after much testing, it was working great since i updated. Then just now, i had another instance where all players were done, and the arena kept going. This time its different though, there were zero errors in my console, and a /ma force end did fix the situation. Ill let you know if it happens again. @garbagemule

Edit: Here i am 45 minutes from this post, with a never ending arena again, and again no errors in console. You have my config above, lmk if you see anything.

Edit 2: It happened twice more, but now its gotten to be a pain so ive disabled mobarena untill we can figure this out. Ill enable it for testing when you figure out what needs tested or anything like that, not sure what to do honestly

 

Cool i have an idea and if there is only one player and they punch the iron block give then a mess saying you area the only one are you sure you want to fight?

 

here's one i just noticed. when using max-join-distance if you out of the set range it will clear your inventory

 

Omg Im starting to get annoyed. So when I do /ma join, it will send me to the lobby. After that, when I pick a class, Nothing happens! I restarted my server, configured the file, everything! I can't seem to pick a class. The class name on the signs are in color. Can that be the problem? HELP!!!! I CANT PICK A CLASS D:

 

What plugin do you use that adds color to signs? I'd say remove it, try again.

 

Why wont the force-restore work for me? And when I set the protect: false it still is protected and blocks destroyed just get replaced right away like before. But I really want to get the restore thing working, that is just a awesome feature. Someone please help!

 

@GameOverRules
if you want to make changes to the arena you have to use /ma editarena <arenaname> [true|false], that will let you edit it how you need to.

@ericnx use the same command above and redo your signs with no colors and see if that works. as in break them off of the wall, then put them back on with normal (black) text

 

I used ColorSign.

 

is it updated yet to 1.7 ?

 

yeah i Know how to edit the region but I am talking about the setting force-restore so that the region will be destroyed during that game and at the end it will regenerate and be good as new.

EDIT: I got it working, after a hr or two or playing around with it

 

Yes. Nvm It's working now. thank you for the help

 

Is there a bug where waves stop spawning after 2?

 

anyone know how to add spawns to an non-default arena after you done the initial setup? when i use /ma addspawn it wants to add it for default

EDIT:

Figures it out /ma setarena

 

yes i have had this evar since he release the patch with all the sick-ass features!!! i want those features sooooo bad!

 

This is my config file and i am having errors. Can I even add new classes to my arena?

@needhelponautoannouncer Use a [code ] block please...

Your missing the armour line in the new classes, if you dont want them to have any just add the line and leave the values blank.

 

@KrazyBonez - Sorry you're still having trouble. I'm running out of ideas as to what could be causing this, but I will be pushing v0.93.2 some time today (hopefully), which has a somewhat altered code structure. I would really, really love it if you could figure out some reproduction steps. It is extremely difficult to debug when I don't know what I'm looking for

@ewized - Fair idea, not gonna get implemented at this point in time, though. Still too many bugs to weed out

@Safetybrick - Thanks for the bug report, and a big "whoops" on my end! Sorry about that. I'll have a look at the order of error checking in /ma join.

@ericnx - Maybe you should try following the Troubleshooting-steps in the main post instead of getting annoyed? Was it the colored signs that messed it up?

@GameOverRules - Try with soft-restore: true. force-restore shouldn't be used unless you can't use soft-restore. Glad you found your error though - would you mind sharing with the rest of us?

@James4119 - I'm not sure exactly how to answer that question. I think I'm going to answer it with another question: Is CB #953 updated to 1.7?

@topsub - Apparently some other users are experiencing this issue as well, but I can't reproduce it. I need more information, and I need you to follow the Troubleshooting-steps to see if the problem is a conflicting plugin. If not a conflicting plugin, then there's something else wrong on your end

@needhelponautoannouncer - I need more information than that, and please, edit your post and put the config-file in a CODE-block (you will need to copy/paste again, because you messed up the formatting).

@columb - Why are you trying to edit my Wiki?

 

Woo nice, been waiting for the iConomy support for a while! Thank you.

 

Hey mule, the wiki link to the commands is broken and it seems the commands arent on the wiki any longer?

 

@Zothen - Looks like someone deleted it... Wiki editing is no longer public, and Commands is back up. Thanks for notifying me

 

I edited a bit before @garbegmule as there was a FAQ question missing

 

I wish i could narrow it down but the console isnt giving me anything when it happens, no errors, and it just seems to happen at random. No true known cause at this time, i may do some more testing later.

 

Yes!
but i still want to be able to make our own
also, when i made my own class and punched it, the server kicked me and said "an internal server error occurred".
this is what it said in console:

my new class is matthewpipie, my username
does it have anything to do with the
armor: 0,0,316,0?

also can u add a new feature that only lets some people use certain classes

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@garbagemule
Any chance of SQL support soon? Maybe for performance restoring blocks could use SQL, coords and other stuff in SQL, thus preventing alot of I/O errors. Also any chance of configuring arenas with commands instead of using the config file like /ma set arenaname arenasetting true/false???
These two features would dramatically increase the server admin's ability to get things done quicker as well as preventing some fail user YAML bugs from bad formatting and lastly some performance gains

 

@matthewpipie 0 is the air block so that would cause an error. try with just that one piece of armour
