Bukkit

@GameCharmer

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.

@d4rkwarriors

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?

So small question. I have the newest version, and on my creative world there is a castle made of the new Stone Bricks, like strongholds are made of.

Well, the Dynmap does not SHOW the stone bricks..Everything else yes, but not those. Is this due to an error installing or is it something out of my hands?

Edit: I reinstalled the newest version of Dynmap and it's appearing as it should now. It was an issue on my part. Thanks for the great Bukkit plugin!

how to add custom link of minecraft skin? we have our skin system with previus version we replace minecraft.net with our link, but with this new version i am not able to find out where is the link that plugin retrive player skin!

thanks alot great plugin

Love this plugin! I tried out 'high-res' template and my god.... I was blown away by how good it looked! I mean the file size was about half a GB, and I didn't even finish because it took so long but I'm pretty amazed by that!

The 'experimental' Multiple thread thing in the config works great though! Never had a problem. I'm using 5/6 of my cores to render. Cuts it down from 100 msec/tile to 20 msec/tile! Great job! :)

@ElectronicDrug

Aye, it works for me as well. I just got some more people from different countries around the world to test it for me as well and it all works fine. I'm guessing those few (2 only actually) that can't connect to it have permission/port blocks- troubles with their routers or firewalls. :)

@Fluffierbunny

Works for me.

I was wondering if I have to change any setting to allow other players to see it. I can use the map perfectly fine myself, and those around me as well, but others get the message that their browser could not locate the map. (cant establish a connection)

For reference, the map would be located here: http://edolas.gaming.multiplay.co.uk/ (click on DynMap)

Also, I'm using 0.22.1 and got: dynmap: version 0.21.1 is enabled

Hi, is it possible to show player markers only on SOME maps? I want to have a sort of assassins world but without player markers but I also have a regular survival world where I do want the markers.

@danielhep The usage of RAM (and the general performance impact) is mostly depending on the number of active players and the map-types that are being used. On my 1GB Minecraft server Dynmap doesn't impact the server much with the low-res HD-flatmap and 5 players, but it might not be a very heavy use-case. I've heard of big server (40 players) running Dynmap without problems, however I do think they have stacked their servers full of RAM.

@ablac

There will be a way to login with a username somewhere in the future, dynmap will use that username for chat when that's implemented.

@LimeByte

Can you send me your URL? (PM or here)

@YukiS

Try the latest development version (http://webbukkit.org/jenkins/public/dynmap/dynmap-0.23-bin.zip) it should be fixed in there. You can also set 'showlabel: true' if you want to keep 0.22.1.
