Changes

• [Added] Combined 'playerenterexit' property to set both at the same time
• [Added] Can now set true/false properties using a statement (redstone, check for tag, etc.)

Some issues showed up early after the v1 release which have been fixed

• Client d/c when adding an attachment in the attachment editor on 1.19
• NPE when pathfinding runs on a world without any trains
• Redstone-activating a powered rail didn't cause a train to start moving (similar with activator rails)

Requires new BKCommonLib 1.13.1-v1. Addons will have to be updated also! (1.13+ support updates)

Adds support for Spigot 1.13 and 1.13.1. Past versions of Minecraft are (of course) still supported.

Highlights

• Adds support for Spigot 1.13 and 1.13.1
• Fix single-cart trains spawned in reverse by spawn signs
• Fix wait distance signs and property, to interact better with custom rails such as TC Coasters
• Bugfixes & performance improvements

Changes

• [Added] Support for Spigot 1.13 and 1.13.1
  
• [Fixed] Single minecarts were spawning in reverse when spawned by spawner signs. Most visible with custom models.
  
• [Fixed] Wait distance did not work properly with TC Coasters rails. Now it does!
• [Fixed] Signs sometimes not triggering when two rails are next to each other, but not connecting.
• [Fixed] Launching and stopping trains slightly inaccurate when a speed limit higher than 0.4 was used. Stations not centering trains properly, then.
• [Fixed] Vanilla Minecarts don't support roll, so some roll caused really glitchy behavior. This problem has been reduced.
• [Fixed] Waiter sign automatic distance calculation
• [Added] Drive effect sign format, to play a sound when the minecart starts moving
• [Fixed] Improved performance, reducing TPS lost due to refreshing rail information by doing this less often.
• [Fixed] Improved performance by caching the Sign State information together with the Sign Block, avoiding unneeded extra lookups
• [Fixed] Without the train.command.editor permission, players can not use the attachment editor map. Before creative players could hack-give themselves the map.

This version of Traincarts builds upon previous release in January, fixing a lot of bugs that were reported over that time period.

Included is a new and improved rail physics API that breathes life into TC Coasters, a new add-on for Traincarts. Please check out the new Spigot page for more details!

New features are implemented for the attachment editor to make it even more powerful. You can now duplicate nodes, change the order of nodes, have bogie tracked models and baby scale item models.

No longer will players move trains that have a custom length set when walking besides it. These unwanted collisions due to Minecraft's poor collision code are filtered out now.

Performance wise a lot of stuff happened. Most notably, you can now disable block collisions for trains entirely. This is not only useful to stop trains from being stopped by blocks, it also helps performance tremendously. Using BKCommonLib 1.12.2-v5 is strongly recommended.

Important note when updating: after updating your train models will look weird or distorted. This is because the pivot point, basically around what point the node rotates, was changed to better match Minecraft behavior. You can correct these distortions using /train upgradesavedtrains.

• [Fixed] Some permission nodes had a typo and started with 'tran' instead of 'train'
• [Fixed] Elevator sign not teleporting trains up/down to non-standard rail types
• [Fixed] Some tags not matching correctly, added [email protected] enter direction statement
• [Removed] legacyVerticalGravity setting (broken)

Attachment Editor

• [Added] Small (baby armor stand) item attachment mode options
• [Added] Duplicate button in attachment editor (thanks to MinePlayer64)
• [Added] Change order implemented in attachment editor
• [Added] Attachment anchor property in position options: make attachment front/back wheels controlled
• [Added] Hold shift in attachment editor to move around
  
• [Fixed] Dropping items in the attachment editor menu did not preserve display name, enchantments, unbreakable
• [Fixed] Attachment editor now refreshes when changing the cart being edited
• [Fixed] Attachments now correctly pivot around the base coordinate (changes height/position of attachments!) This means saved trains will no longer look correctly. To fix, use /train upgradesavedtrains.

Performance

• [Added] Entity and block collision property improve performance when disabled
  
• [Fixed] Better error handling where a misbehaving add-on caused error spam
• [Fixed] Improve performance by only detecting nearby minecarts once when spawning (linking)
• [Fixed] Improve performance of chunk tracker
• [Fixed] Improved performance of mutex zones and wait distance property

This new installment adds long-awaited new features. Most prominent is the new attachment system, which allows you to add item/entity attachments to minecarts. This enables everything from 'mob trains' to custom resource pack models being used!

I have updated the main plugin page with a new feature video to cover all this

You should definitely update BKCommonLib. It does not work otherwise.

The old Floatrail plugin does not work with this version of this plugin. Use TC-Hangrail instead, the latest version offers support for custom blocks as rails.

Highlights

• Attachment editor: custom 3D models for trains and multiple seats per minecart
• Wheel tracking
• Persistent orientation

Changes

• [Added] Minecart attachments and attachment editor ('models')
  • Convenient Map Display UI (obtain using /train attachments)
  • Display custom 3D models from resource packs in place of vanilla minecarts
  • Configurable position and rotation of attachments
  • Configurable minecart length and wheel positions
  • Multiple seats per minecart
  • Attachments: empty, seat, entity, item
• [Added] Timings statistics for TrainCarts behavior
• [Added] Rail physics rewrite with new features and improvements
  • Rail path system
  • Wheel tracking for smooth turns in curves
  • Orientation calculated from wheel positions on rails
• [Fixed] [Station] Stations incorrectly cancelling launch instructions from other stations
• [Fixed] [Spawner] Initial spawn positions + fixes occasional glitching through ground on spawn
• [Fixed] [Spawner] Automatic spawn sign was behavior erratic at times / duplicate spawns - fixed
• [Fixed] NPE when train being updated loses all carts
• [Fixed] Client d/c on Bungeecord when players go upside-down
• [Fixed] Now has realistic and persistent Minecart orientation
• [Fixed] Now maintains proper distance between Minecarts at all times
• [Fixed] Owner not always set when players place down minecarts
• [Fixed] Trains losing linkage when unloading/reloading sometimes
• [Fixed] Player take incorrectly set to true by default (unwanted feature)

• [Added] Minecart banking in curves - only really functional with custom models
• [Added] Flip sign, for flipping around the orientation of a Minecart 180 degrees
• [Added] Saving trains under a name, saved trains can be put on spawner signs
• [Added] Always-off power mode for signs (-train)
• [Added] Configuration option to turn off third-persion view on vertical rails
• [Added] Configuration option to turn off the 'eject' behavior of activator rails

A lot of new features, the obvious one being: loopings! Requested for so long, it is finally here!

• Full implementation of upside-down rails: placement, block physics, train physics, disable block suffocation damage (survival)
• Full implementation of upside-down network synchronization logic: render players upside-down
• Vertical and upside-down rails: correct the camera position of the player to not clip through the minecart
• Fixes to vertical <> (upside-down) slope train physics
• Correct display and synchronization of minecart rotation
• Implement a new train motion physics system that much better supports "air jumps"
• Fix manual minecart movement not working (vanilla, press W to move. Only when enabled through properties)
• Fix minecarts being selected for editing when they are being destroyed (don't lose selection when destroying with hand/arrow)
• Added a new 'wait distance' property for trains, to maintain distance between them and trains up ahead automatically
• Added a 'mutex' sign, to avoid multiple trains crossing a junction

General bugfixes as reported through Github and elsewhere. Unlike the version says, this version also support 1.12.2 through the latest official build of BKCommonLib.

Bugfixes:

• Fixes a bug where some Mac (keyboard) users could not write TrainCarts signs due to an inserted meta character
• Now refreshes the speed limit set for a train during a station or launcher launch, enabling smooth ramp-ups/downs based on the speed limit that is set
• Displayed block in the minecart (block changer sign) can now also be set using Default Train Properties. (see end of post)
• The speed displayed on /train info and trigger signs was not limited by the speed limit. This has been fixed.
• There was a sign activation bug for TCFloatRail (and Hangrail) caused by the sign search function, which has been corrected.

Set displayed block through default train properties
Below are two examples of default train properties that set the block to air, or a trapdoor, when applied, while at the same time setting enter/exit permissions.
This can conveniently be set with the property sign using the less-known setdefaults:

Skipper sign
This sign will, when crossed, tell the minecart or train to skip certain upcoming signs. Useful for making trains ignore a particular station or as a sign activation filter.

Slowdown modes
Slowdown changed from a simple boolean to allow for specifying what kind of slowdown is enabled or disabled. This introduces two new commands:

• /train slowdown gravity [true/false] - turn gravity-based slowdown/speedup on or off
• /train slowdown friction [true/false] - turn friction speed reduction over time on or off

Likewise these can be set on property signs:
In default train properties/properties YAML, these are saved as a node replacing the old true/false.
The old true/false slowdown properties still function and set all (both) modes on or off simultaneously.

Fixes:

• Slowdown false works properly on vertical rails
• Vertical rails have the same gravity-based slowdown as sloped rails. To change it back to the broken old values, set legacyVerticalGravity to true in the config.yml
• Fix a potential invalid block collision when taking a curve down a slope
• Minecarts are now edited automatically when placed on non-standard rails (vertical rails, pressure plates, etc.)
• Tickets # uses not updating when entering a train

As always, this version is backwards compatible with older MC versions through BKCommonLib.

Changes:

• Switcher sign bug-out has been fixed
• Bugfixes related to keepChunksLoaded
• New ticket feature!

By popular demand, new train ticket system is now included in TrainCarts. Restrict access to trains by handing out train tickets, and automatically send trains to the right place based on the ticket used. I will make a proper tutorial video once I have the time, for now, this video will have to do for demonstration:



New commands:

• /train list destinations - see all destinations
• /train list tickets - see all tickets
• /train ticket create [name] - create a type of train ticket
• /train ticket edit [name] - edit an existing train ticket
• /train ticket clone [name] - clones the ticket currently being edited under a new name
• /train ticket rename [new_name] - rename the currently edited ticket
  
• /train ticket maxuses [num] - set the amount of times the ticket can be used before expiring
• /train ticket destination [name] - set a destination, applied to trains when entered with the ticket
• /train ticket tags [tags...] - set one or more tags added to the train when entered with the ticket
• /train ticket give [name] [players...] - give an instance of a ticket to a player
• /train ticket realm [realm] - set up a ticket realm (see below!)
  
• /train addticket [name] - adds a new ticket to a train. As soon as a single ticket is added, access is restricted unless the player possesses one of the tickets added.
• /train remticket [name] - removes a ticket
• /train setticket [name] - clears old tickets and sets a single new one

addticket/remticket/setticket also work on property signs.

Lacking commands right now, you can edit tickets.yml manually and set up an expire duration in milliseconds (real time) or mark tickets as player-bound, so only the player that was given the ticket can use the ticket. You can also let tickets define properties other than tags/destination that way.

Realms:
A complicated feature perhaps, so I'm giving it its own header. You can assign a realm to a ticket, which makes it easier to bundle multiple tickets together. Say, you have many tickets to apply to a train because you have dozens of destinations in your network. By setting a realm, and then assigning the realm name as a ticket name to the train, you simplify managing it.

For example, I have two tickets called 'TicketA' and 'TicketB'. For both tickets, I use /train ticket realm MyRealm. Then I assign it to the train using /train setticket MyRealm. Now players can use both TicketA and TicketB on the train. You can still put 'TicketA' as ticket for the train to only allow one.

• Multiverse-Portals can now be teleported to using a train teleport sign
• Nether portals support train teleportation to and back from/to rails nearby the portals. Does not work with a player in the front cart (Bukkit bug), can be avoided by putting a dummy cart there like a storage cart
  
• Fix a case of "unknown location of EntityMinecart" resulting in missing trains on server restart
• Implement an auto-save to prevent data loss when server crashes or fails to shut down properly
• Fix a bug where a launcher/station can derail a train when launched onto a curve
• Fix sign posts not being activated for trains going down a slope
• Activator rails eject players/mobs from minecarts when powered (vanilla behavior)
  
• Detector sign regions re-create themselves when a train drives over either sign (if one does not yet exist) to ensure persistence
  
• Uses new API in BKCommonLib (if latest version) to further reduce cpu usage

Train teleport format:
Which will teleport to MyWorlds or Multiverse-Portals by name.

Special thanks

I would like to thank all these people for submitting excellent bug reports that helped furthering this project. Thank you!

(GitHub) MinePlayer64 for submitting many bug reports, feature requests and providing support along the way. Station/launcher fixes are partially thanks to him!

(GitHub) david50407 for submitting issue requests relating to crafting and inventory transfer, and also train physics.

(Spigot) GamerKM for providing issue and bugfix information

And perhaps some others too! Remember you can report issues on our GitHub issue tracker or you can send Team Bergerhealer a pm!

Many long-standing bugs in the previous release have been fixed. Some are still pending a fix or need further confirmation, which will be listed further down. Please use the latest BKCommonLib (1.11.2-v2), which includes some of the below bugfixes and more. This build supports Spigot 1.11.2 and 1.12-pre5, 1.12-pre6 (tested)

Bugfixes:

• Fixes a bug where you could not interact with minecarts
  
• Fix minecart displayed block data wrongly applied
  
• Fix errors when loading collision modes
• Fix teleport sign not always teleporting
• Fix vertical rails not triggering signs
• Fix spawn signs not working on vertical rails
• Fix minecarts not playing any sound when on vertical rails
• Fix collect/deposit signs always dropping items on the ground
• Fix furnace minecart sound loop not playing
  
• Catch errors in third-party rail plugins (such as TCHangRail) and disable such rails when they occur to prevent hard-to-track-down errors that render TrainCarts unusable

Changes in minecart rail physics:

• Minecarts now collide with low-hanging ceiling blocks to allow vanilla-style minecart piston stations to function. This can be turned off in the configuration
• Minecarts no longer go through blocks perpendicular to a curved rail when derailing, causing them to be stuck there
• Minecarts no longer go through blocks above a slope
  
• Vertical rails have altered physics when going from slope to vertical, which may have very slightly impacted their height reach. Check your attractions!

General bug reports that have been verified and fixed:

• "If you place property speedlimit signs on a ladder rail (looping or dive drop) the cart won't listen to the sign."
• "Minecart goes through the wall when encountering a derailed curve"
• "Furnace in not working"
• "train spawning on ladder goes either up or down, no consistency"

Some things that may have been fixed:

• "Detector sign not working - stays active" (failed to reproduce)
• "Cross world teleport not working" (failed to reproduce locally)
• "Trap Doors show off at an offset" (they dont appear to)
• "Cant put multiple signs underneath each other" (appears to work)
• Fireworks causing strange issues with minecarts. Changes have been made to prevent it, but it is not verified as fixed.
  
• Several odd station sign related physics bugs, which are hard to reproduce because of how large the track has to be. If you encounter these, for now try changing the station sign 'length' so it does not launch too large distances.
