介绍

设置三个目的地和一个转辙器来调度列车。

通过自动切换轨道，列车理论上可以到达 Minecraft 世界中的任何位置。通过放置控制牌来配置轨道网络拓扑，预先配置的列车将遵循该拓扑来到达目的地。

列车到达的地点被称为目的地，由目标牌指定。切换轨道的位置以及终点的位置被称为节点，由转辙器指定。如果要强制某段轨道路线只能单向行驶，可以设置阻挡器来阻止相反方向的路线。

开始

指定目的地

可以在目的地标牌的第三行输入目的地的名称，第四行可以填写新的目的地名称来为经过的列车设置新的目的地，但你也可以留空不设置。

• 

  车站与目标牌。当列车到达此地时，会停留30秒，然后向右驶出。

指定切换节点

Places where the track should be switched need to have an always-powered switcher sign placed. Now when a train moves over it that has a destination set, a route will be calculated and then the track is switched.

• 

  Switcher sign will automatically switch the track to go from/to any of the 3 directions.

Enforce one direction

When it is desirable that trains only ever go in one direction over a piece of track, an always-powered blocker sign can be used. This is useful when having two tracks side-by-side, each going in opposing directions. The path finding system will automatically ignore paths that are blocked by blocker signs.

• 

  With [+train:left] trains coming from the left are blocked, only allowing movement from right to left. Similarly, [+train:right] and other directions can be used.

Test it out

Place down a minecart on the track, and use the Destination command to set a destination:

/train destination [name]
/train destination output

Now give the minecart a push towards the switcher sign, and observe how it will automatically switch the track to send the train towards the destination. You can change the destination again and send it to the switcher again. Continue to experiment with multiple switchers, blockers and destinations.

If you run into a problem where the switcher appears to make a mistake, use the Reroute command to force a recalculation of all routing information:

/train reroute

It is also possible to use the property sign to set a destination:

[+train]

property

destination

outpost

Advanced

Once the basic system is understood, there are some more complicated features to discuss.

Useful Side-Features

Keep Chunks Loaded

Prevent trains unloading when no player is nearby or in the train, by enabling the train keep chunks loaded property.

You can use this property sign to set it:

[+train]

property

keepchunksloaded

true

Or you can create your train, use /train keeploaded true and save it under a saved train name using /train save name. You can then automatically spawn it by this name using the spawner sign.

Wait Distance

To maintain distance between trains and avoid collisions over long stretches, use the wait distance property.

Mutex Zones

Protects intersections against collisions with mutex zones.

Station Routing

Station signs can launch the train into the direction of the next destination.

[!train]

station

route

Debugger

Displays the destinations with a distance to them

The plugin offers a debug stick with which path finding information can be displayed. Use the stick item to click on rails to show information about the route(s) that can be taken. Sneak (shift) while clicking performs a reroute, which recalculates the track reachable from where you clicked. If you have multiple smaller rail networks, this can be more efficient than executing the global reroute command.

All destinations

Use the following command to get a stick item that displays all destinations reached from a given track:

/train debug destination

The track clicked is followed until a node of the track network is found, after which all routeable destinations are listed. For every destination the total distance to it is listed, and particles are displayed leading into it. If you find that a certain destination is not listed that should be, you can move further along the track clicking occasionally to find where the break is.

A single destination

Displays the precise route to one destination

Use the following command to debug a specific destination:

/train debug destination [destination]

Now when you click on the track, particles are displayed what route is taken to reach the destination. This is useful when debugging a specific destination so no particles are displayed for routes and destinations that aren't relevant to you.

Route Manager

Normally only one destination is set at a time. It is possible to set the next destination to go to on the destination sign itself, but that means you can only have one possible route. With the route manager a list of destinations to visit can be configured, and then applied to trains. Trains will then go down this list, advancing it every time they pass by a destination on it.

Commands

First, edit a train, then use the following commands to set a list of destinations:

/train route set [destination1] ([destination2] [destination3...])
/train route set outpost hillfort dungeon

To add additional destinations to the existing route, or to remove them, use these commands:

/train route add [destination1] ([destination2] [destination3...])
/train route remove [destination1] ([destination2] [destination3...])

You can then use the destination command or property to start the route at a desired destination. Otherwise, the route is started from the beginning the moment the train hits a destination sign. To inspect the route of a train, use the base route command. The current destination the train has is highlighted green.

/train route

Persistence

The route of a train can be saved globally under a name so it can later be applied to other trains instantly.

/train route save [name]

To load a saved route, this command can be used:

/train route load [name]

Alternatively, it can be done using a property sign as well:

[+train]

property

loadroute

myroute
