GLOSSARY
general
BED
Usually refers to piston updating other pistons in a chain reaction within a single game tick. Since pistons activate during the block event phase of the tick (kind of) and things execute in the order they are scheduled, having something be activated by a piston that was updated by a chain of three other pistons before it (BED 3) will always happen before something that was activated by a BED 5 event.
方块事件深度/方块事件延迟
方块事件延迟/深度。通常指在单个游戏刻内，活塞通过链式反应更新其他活塞。由于活塞在游戏刻的方块事件阶段激活，且按调度顺序执行，由三个活塞链更新触发的活塞（BED 3）总比由五个活塞链更新触发的（BED 5）先发生。
