TrainCarts/Signs [zh]

TC可以通过使用告示牌来为列车或单个矿车执行操作。

结构与行为

几种控制牌的语法格式。

控制牌的格式始终遵循统一的结构。首行需标注cart或train，用于指定控制对象是单个矿车还是整条列车。随后可选择性设置控制牌对红石信号的响应方式，以及接收红石信号的方向（此方向即为矿车驶出的方向）。

红石

控制牌需通过红石信号激活使用。如果不使用红石来激活控制牌，它就只是一个普通的告示牌。如果不想红石来激活且控制牌依然能够运行，可将告示牌的第一行改为[+train]。

控制牌充能模式

第一行	释义
[train]	默认模式。当使用红石信号激活时才会运作。
[+train]	激活模式。控制牌会一直运作，无需红石信号激活。
[!train]	反转模式。类似于非门，被红石信号激活时不运作，无信号时运作，无红石信号激活时工作状态与[+train]相同。
[-train]	无法充能模式。控制牌不接受红石信号。该功能只适用于转辙器。
[/train]	上升沿模式。控制牌只会在红石信号由关到开时工作一次，不会对经过的列车作出反应。
[\train]	下降沿模式。控制牌只会在红石信号由开到关时工作一次，不会对经过的列车作出反应。
[/\train]	双边沿模式。控制牌在红石信号切换激活和不激活时工作一次，不会对经过的列车作出反应。

拉杆输出

控制牌可切换拉杆来间接输出红石信号并激活其他相邻的控制牌。只有少数类型的控制牌才具有此功能，例如列车停在车站牌上方时就会切换拉杆。

激活方向

默认情况下，列车只有能看到控制牌的正面或侧面时，该控制牌才能对列车生效。因此，要使控制牌起效，控制牌应当面对矿车驶来的方向。要覆盖此功能，你可以在第一行添加“:”（英文冒号），后跟一个或多个方向参数。如果你想让控制牌在所有方向上都能生效，可使用通配符，用法：[train:*]。

示例：某道岔牌上写入[-train:lr]，当列车从左侧或右侧进入时，控制牌会切换左侧和右侧的拉杆，使其进入激活状态，而其他方向的拉杆不作反应。此控制牌使用-train来关闭道岔牌切换铁轨的功能。

远程控制

少数类型的控制牌支持远程控制：通过名称控制列车。用法：[train <名称>]，或使用缩写 [t <名称>]。远程控制牌仅对红石信号的开关变化作出反应，因此放置的位置并不重要。类型表列出的是支持远程控制的控制牌。

远程控制可操作多辆列车。与标签相同，远程控制使用“*”来表示要操作的列车。例如，下面的控制牌会将所有名为“intercity”的列车的目的地设置为home：

[train Intercity*]

property

destination

interhome

你可以用它来轻松调用所有列车。如果你使用标签来调度列车，你也可以添加新标签来让列车返回。

Placement

Empty minecarts are blocked

Trains are switched left and right using a 1:1 counter

Each sign targets a certain track piece above. Signs attached to walls take the block they are attached to and look up until they find a piece of track. That track is then used for that sign. Sign posts look up until they find a piece of track. There may not be blocks without signs between the bottom sign and the tracks.

You can make a pillar of blocks below a single track piece and attach signs to it, to make a bundle of actions on a single track piece. Trains look down when they enter a new track piece to check for signs, so make sure you put the output signs above the signs that use this output for correct results.

A noticeable exception would be add-ons for the TrainCart plugin, which may change the (relative) position a sign would need to be placed on in order to work for the track. For example, would the TC Hang Rail add-on require you to add the signs above the Hang rail track to work, while the TCC (TrainCarts Coasters) add-on uses the block of a node for the sign, which can be moved to any other block.

For most signs the sign direction influences what happens, as also discussed earlier (Activation Direction):

• The train has to face the text on the sign to make the sign respond
• Signs with the same alignment as the tracks (faces to or away from the tracks) always respond
• The train is spawned in the direction the sign faces

Permissions

Each sign has a separate build permission. See the main permissions page. For using remote control, the player requires the train.build.feature.remotecontrol permission which is OP-only by default.
