    After a request from Marius A. Winsjansen I started to work on linked Minecarts. On the first day I already managed to make multiple carts move with the same speed, but a long list of bugs was to be expected. After fixing lots of bugs, adding lots of (complicated) Minecart handling functions and after hours of testing on my local server, this plugin is finally ready for a stable release! :D

    Also, special thanks go to @Shamebot for helping me out several times. :)

    For a lot of information about TrainCarts see the WIKI page!

    Configuration and permissions

    All configuration nodes can be found in config.yml and contains a description with it. Permissions can be found in PermissionDefaults.yml, combined with a description.

    Video of how the switcher, station and destination signs work together

    Side information:

    It works best on straight lines with not too much elevation changes followed up by sharp corners. As long the cart gap can be adjusted, everything goes fine. It had some collision issues in the past, but I fixed all of that by manipulating the actual Minecraft server native code. I added links in the source where this was appropriate. Sharp 'U'-turns cause individual carts to lose perceptive of their direction. Keep at least one piece of track in between corner sections! Trains are stored on-disk when reloading and stopping the server, so expect trains to be there when you return.

    Important when updating: do one reload to save all trains, then replace traincarts.jar, and then do another reload. This next reload will probably cause a noClassDefFound exception (since the old jar got replaced), this is why a pre-reload is required. Replacing the jar without reloading is a very bad idea: it will cause a lot of runtime exceptions. Best is of course to stop the server and start again, but this is not always possible.

    This plugin is made compatible with Minecart Mania. If you notice a certain feature of Minecart Mania is not compatible with TrainCarts, notify me and I'll fix it. :)

    Known bugs:
    - None.

    - Train-sign message handling using SignLink (low priority)
    - Minecart use permissions (for individual carts?) such as Storage Minecarts


    If you encountered a bug, post exactly what you had done and in what order. Even a slight wobble can help fixing bugs. When posting (long) errors I recommend you to post everything, don't cut it off. I work with native methods, so in my case these lines are important. For comments on the media content see YouTube, it also contains a description with the music name when music is used.

    Bug reporting (extend)

    1. Post the Craftbukkit version you are using (the first info message in the console)
    2. Post the log from where the first plugin gets enabled to the 'done'.
    3. Post possible errors in this log too (don't cut them short)
    4. No error? Still post the log. Also explain how I can reproduce it, you can use screenshots
    5. Before reporting, remove ALL plugins other than TrainCarts and try again. If it works then, find out what plugin is interfering and post that here. I can add support.
    6. ALWAYS use the latest recommended Craftbukkit build with this, or my methods may just fail because of renamed functions.

    Important links:

    Request thread
    TrainCarts on BukkitDev for download and more
    TrainCarts source and more on GitHub
    TrainCartsBlocks add-on source and more on GitHub
    SignLink Bukkit page (required to use Arrival signs)
    MyWorlds Bukkit page (required to use Portal train teleportation)

    notice: try to keep SignLink/MyWorlds up-to-date to prevent compatibility issues.

    Installation for those that don't know how

    1. Download and install the latest craftbukkit version
    2. Download the latest TrainCarts version
    3. ^ Save the archive (zip file) to your computer
    4. ^ Open the archive you just downloaded
    5. In the folder your server sits in, create the plugins folder if it doesn't exist
    6. Open the plugins folder
    7. Move the TrainCarts.jar file found in the archive into the plugins folder
    8. Run your craftbukkit server and look in the console/log for possible errors, and/or if the plugin is enabled.

    Well, it's very buggy :(

    If you try to take a curve with 3+ minecarts they will get stuck if there are adjacent blocks to the rails... etc.
    Sorry but i'm not using it for now.

    EDIT: NVM, I messed up with the config file and now it works perfectly :D

    Great plugin!

    Sounds great! I'll check it periodically to see when it's fixed :D

    Ok so I now use:
    Instead of:
    The first one works, the second one leaves weird ghost Minecarts behind which I can't remove. However, the first one is set with a delay; it gets 'cleaned up' upon the next tick. This next tick is why a reload spam causes it. Now finding out what this cleanup is so I can do it in one go, hopefully I'll end up with a solution...

    Updated TrainCarts to 1.26 fixing (maybe) quite some bugs I randomly encountered during various test-runs...
    Also added a station delay (in seconds) on King's request. :)

    in 1.26 i have a problem - train ingoring obsidian block from Minecart Mania
    tested on cb1060 only MM and TrainCarts
  6. Offline


    @MechanID ok I'll look at it. Btw if you use 1.26, download again for a temp. 1.27 (not official though). It fixes an annoying ghost minecart spawn bug during reloads.


    Are you sure you didn't power the obsidian block? It doesn't stop carts when it's powered, then it launches them...
    If you used a certain sign underneath, tell me which one so I can debug it properly.

    Ok officially updated to v1.27 fixing the bug @js105287 mentioned. Ghost carts are history. :)

    If it didn't include this:
    This means it didn't even detect Minecart Mania, didn't hook into the library and doesn't use it at all. Could you verify if this line is present or not?


    Since when does Minecart Mania load BEFORE TrainCarts?! Ow well, I'll fiddle a bit with the plugin.yml...


    Ok added a simple softdepend: line i nthe plugin.yml to ensure MM loads first. Try re-downloading it now...
    Note: didn't mind incrementing the version for something unnoticable...

    I am experiencing a bug where, trains stop as they pass across pointwork. They stop dead.
    Only seems to happen on trailing points. Leading points are fine.

    The setup I have is two parallel tracks with a crossover so that trains travelling on the right-hand side will be routed over to the left-hand side (see attached image).

    This appears to happen with all trains (that is, 2 or more cars. Although, much more likely to occur with 3 or more).
    With my track layout this happens every time they pass over the points.

    N.B. The colors in the attached image look a tad wierd because the image was taken
    at night and adjusted to make it clearer to see.

    @SergeantH Same as before I can't seem to reproduce is pretty obvious how to reproduce it and what seems to happen, but it doesn't happen when I try it out: they simply move on...

    I tried all 4 possible directions a train can come from, all worked. Also the other 4 of how they take the turn...

    You are using the latest version & are you using possible other plugins that change Minecarts? (FalseBook vehicle, CraftBook vehicles, Minecart Mania, some others I don't know). Errors in the log?

    Also, any obstacles in the setup (like a piece of fence on the sides) or did you try it out this clean?

    Uploaded a file to show the overkill I had to use to get this effect...

    Please tell me, can i disalble somehow constant speed of trains ? when i use TrainCarts with MM, because it is confusing when train formed from only storage minecarts moving non stop on standard rails even up to the hill.
  19. Offline


    It's a setting in Minecart Mania, but I failed to find it myself too. Better to ask it in their own thread, it must be a configuration setting somewhere in MinecartManiaConfiguration.xml. Did see this:
    But afraid setting that to 0 will not disable the feature...

    It's AutoCart. We do not use it on my Server ;)

    @bergerkiller I found the problem originally using a double track in a 3x3 tunnel with the track on each side.
    I have found, that in a 'clean' environment (i.e. in a test world) the problem does not occur.
    I did some further experimentation and I have found that only certain blocks around the junction seem to cause it.
    Strangely, those blocks do not always have this adverse effect. Sometimes they just do not effect the train at all.

    i dont use AutoCart on my server too, if you use TrainCarts and MM and havent this problem please tell me what your versionn of MM (each modul) and craftbukkit version

    I have one of the development builds of MM and CB1060. Because of the developmentbuilds I can't give you a better version number, sorry :)

    @SergeantH Now that helps me in debugging it. :)
    I can now limit it down to the onMove collision tester, and the onVehicleBlockCollision event. I'll see what I can do to prevent it...

    I'm having an issue that is severely affecting server stability. Our server has a very large track that connects different geographical locations together, and the track runs in a giant loop around our generated section of world.

    I'm starting to see this error constantly, and it crashes the server when it happens. I can travel around the world cleaning up carts, and the server gets stable with a very small number of trains, but if I send multiple trains around the system to pick up items at different dropchests, I randomly get these crashes when the trains crash or interact:

    It's fixable, but kinda weird it is in the world entity list. I'll do an emergency check there so it will use a solid list of entities. :)

    That would be fantastic. I'm currently walking our tracks trying to catch all the trains to clear them out so our server will stay up more than 5 minutes!! DOH! haha!

    @Aox I do plugin developing for the experience, not to get :p
    And the second error you posted seems to be the cause for the first one...
    I'll have to take a stronger look at the train replacement code again...sigh

    Btw: just before I start fixing a fixed bug: you are using 1.27?
    And also, if you used the 'experimental tile entity fix' of Craftbukkit, try using the recommended build. It could have something to do with that.
