计时器 是一个能周期性激活其他设备的触发 机械 。 鼠标右击可以开启和关闭计时器。
- If a timer A activates another timer B with the same duration, B will trigger before A (thereby deactivating A before it can trigger again).
- Exiting a world and re-entering it resets all Timers to their inactive state.
- The Crab Engine and Bird Engine methods can be used to produce a similar effect at faster intervals.
- The Timer must be placed above another block. It also does not block any creatures from passing through it, so do not use it as part of your wall holding in 1-block-tall creatures such as slimes.
- On the 移动 and , Timers are bought from the 版机械师 instead of being crafted, due to the fact there's no watches in these versions.
- Unknown Mobile Version: Due to removal of watches, no longer craftable.
