探测铁轨(Detector Rails)是一种功能类似于压力板的铁轨,它也是第一个铁轨开关。
当任何一种矿车在探测铁轨的上方时,它会产生一个红石信号。此信号会传输到相邻的方块(包括动力铁轨)以及放置在其下方的红石,就和压力板一样。
制作
制作探测铁轨与普通的铁轨一样,但使用压力板来代替木棍,并加上了红石。
| 材料 | 输入 » 输出 |
|---|---|
| 铁锭 + 石质压力板 + 红石粉 |
使用
探测铁轨具有多种用途。配合音符盒可以让矿车到来时提示玩家,或者与红石火把配合作为道岔提示器。
探测铁轨也可以配合记忆单元用作驱动长铁路中的充能铁轨。
配合充能铁轨可制作只允许单向通行的铁路。
也可以配合发射器制作不允许载人矿车经过的陷阱。
探测铁轨也可以配合其他两种铁轨制造矿车时钟。
漏洞
- Detector rails placed on slopes do not work reliably. They will only turn on if the minecart is traveling slowly, and will usually not activate at all if the minecart is traveling at maximum speed.
- A detector rail being used to change direction on a T shaped track will work as intended from one direction but if the cart is going fast enough from the other the plate can trigger early[1]
- A detector rail powering a line of redstone will continue to power the line for a short time in the absence of a cart on the rail if the detector rail is moved away and back by a Sticky Piston (the cart is not retracted with the rail).
历史
- When the detector rail was first added to the game it could not be placed next to any rail without the game crashing due to a bug.
- If a detector rail was placed on a slope and the next rail had the opposite slope, the detector only generated signals for occupied carts (like a stone pressure plate). This bug was fixed in 1.6.
