TrainCarts/控制牌/方块更改器
介绍
方块更改器可以更改矿车中显示的方块类型。比如，储存矿车内显示的是一个箱子 - 那么显示的方块类型就是箱子。你可以通过这个控制牌将箱子修改为其他类型的方块。所有矿车类型都支持这个控制牌，显示的方块类型不会因服务器重启而消失。
语法
First line: [train] to work on the entire train, [cart] to work on a single cart
Second line: blockchanger
Third and Fourth lines: The block types to set (see: Item format)
The types set repeat: in the above example it repeats every 5 minecarts. The first two minecarts get a wooden block, the next three minecarts a stone block. Not specifying an amount is seen as infinite - which means that the specified block type counts for all carts. The following example shows a train set to use a diamond block for the first cart, a gold block for the next two carts, and empty (air) for all the remaining carts:
If you need more advanced settings, you can combine a [cart] blockchanger with a Switcher to individually set the block type based on per-cart properties. If you need to specify a lot of block types, you can use Item Shortcuts to define a lot of block types at once.
