Directional

描述

A contraption is said to be directional if it exhibits a different behavior when rotated or mirrored. This is usually caused by some internal component being directional itself, which in turn is most often caused by update order: each components notifies its neighbors of the update in a set order (for example, negative to positive z first, then negative to positive y, then x). There are also other causes of directionality.

  方向性

  如果一个装置在旋转或镜像时表现出不同的行为，则称其为方向性的。这通常是由于某些内部组件本身具有方向性，而方向性最常见的原因是更新顺序：每个组件按固定顺序（例如，先从负Z到正Z，再从负Y到正Y，然后是X）通知其邻居进行更新。此外，也存在其他导致方向性的原因。
