Bukkit

@deleted_7536780

I get the same lag spikes, intermittent, was running 1185 and now running 1240. That's why I asked for an offline version so I can just do nightly renders instead.

I was wondering if there's a way to disable all of the "live" functionality and just have it do full renders at nights by having /dynmap fullrender command run once a day. Everytime I run the plugin as is, it just lags everything right out.

Additoinally, just want a flat map, no nether, no caves, anyone can help me with that part of the config as well?

You can check the commit messages: https://github.com/webbukkit/dynmap/commits/master I'm mostly working on an unstable branch, which likely will not yet be included in 0.24, but is for a later version: https://github.com/FrozenCow/dynmap/commits/servlets

is there a changelog somewhere? i wanna see whats new in .24

It seems to be related to Minecraft/CraftBukkit's chunk-loading. Dynmap will make Bukkit (eventually) load all chunks when doing a fullrender, so it makes sense that the error only pops up when Dynmap is running. The strange thing is that it 'crashes' when writing a chunk. This should never happen. It might have something to do with the disk/filesystem/permissions. It could also be a recent change in chunk-handling in Minecraft/CraftBukkit. I've just received a similar report that only happens with CB1317: https://github.com/webbukkit/dynmap/issues/472. What version of CraftBukkit are you running?

is there gonna be a time when you are gone put breaklines in your textfiles?

because right now it just looks so messy

The FAQ shows how to do high-detailed maps: http://dev.bukkit.org/server-mods/dynmap/pages/faq/ To enable Towny, you have to uncomment (=remove the first '#' in front of) the following lines: https://github.com/webbukkit/dynmap/blob/master/src/main/resources/configuration.txt#L171-199

i need a little help with configuring the components. i have no clue where to begin... i'd like to add towny regions and hd rendering, but is there any other cool stuff dynmap can do?

I got a Problem with the day and night nothing will be rendering if i change the config? im on HiRes.. an i want to be day and night here my link survival-builders.de:8123

@Nukufox

Simply reload / restart your server once, it will generate all the needed files!

I just downloaded Dynmap for the first time and can't seem to locate the configuration.txt. I've already uploaded Dynmap to my MC server plugin folder. Do I need to generate this file somehow?

From what I have seen online the configuration.txt file is just inside the dynmap folder, however all I see are 3 folders: colorschemes, texturepacks and web. No configuration.txt

Awesome! Thanks FC! I must have missed the part about parallelrendercnt, as that's pretty much what I was looking for anyway. :)

This would require dynmap to read in the world-files itself. Now we make use of the interface of Bukkit to retrieve the blocks/chunks that are in the different worlds. This has a few big advantages:

1. The biggest: we don't have to implement world-file-parsing and keep that up-to-date across the different versions of Minecraft. It is already quite some work to keep Dynmap up-to-date with the new block-types/biomes that come out every version
2. we don't need to 'reload' the already loaded chunks of the world (the chunks where the online players are at the moment): uses less memory and less IO. For fullrenders this is less of an advantage, but fullrenders usually are only needed once: after installing dynmap.
3. we can make sure there aren't any chunks that have changed while doing the fullrender. While the fullrender (or any render is working) the changes that players make in the world are queued, so those chunks will be rendered when the fullrender is done. We can't ensure this as a seperate process.

All this without inter-process communication, which is therefore fast. It also costs less memory, since we don't need to create a whole new JavaVM in the seperate process.

Also, Mike has added a feature to Bukkit, which allows him to retrieve whole chunks quite fast. As an added bonus, we can access those chunks from different threads, which is why multi-threaded rendering is now possible ;). (the 'parallelrendercnt' in configuration.txt) All in all I think Dynmap allows enough configurations-tweaks to make it perform under most circumstances. Check out 'timesliceinterval' if fullrenders are hogging your cpu. If the main game is underperforming while doing fullrenders (or any renders), you might want to take a look at 'maxchunkspertick'.

I'm not too keen on Java processes, but would it be possible for Dynmap to spawn in a separate process? Have 1 small JAR file determine the path from root and execute the main Dynmap jar vial command line or something? This would/should/could eliminate nearly all lag caused by full renders on upper level multi-core systems. Since the current version of Dynmap allows multiple concurrent full renders, this could drastically speed up the rendering process as well, since each process would not be fighting for CPU.

Even if this was something very simple, such as spawning a new process with a single command line argument (world name) for handling full renders, it couldn't hurt, could it?

Keep the attached Dynmap process for handling the chat, internal webserver, chunk change tracker, etc, but offload the tedious process of generation to separate processes.

If only MC were multi-thread capable. :P

Well, not specific for 0.24, but I have been working in the weekends on authentication and a new webserver. The new webserver should allow other plugins to host webservices, just like Dynmap does. Authentication allows people to login on Dynmap, so you can set permissions for what people may do or see on the map. After that all kinds of cool features are possible which at the moment would cause chaos since everyone can use them. It also should (finally) resolve the problems with usernames in webchat.

Mike's got some big and awesome render-features planned, but I don't know when he'll work on that. Lately the Minecraft updates requires quite some work on Dynmap, Mike keeps the rendering up-to-date with those changes.

The url where dynmap fetches the skins is hard-coded atm, but you can just disable 'fetchskins' in the configuration and put your own versions of the faces in dynmap/web/tiles/faces/*x*/.

Just dropping by to say thanks again for an awesome plugin and helping my server look beautiful.

Do you guys have any big changes planned for 0.24?
