方块
方块是占据世界空间的基本结构单位。
碰撞箱是一个玩家无法穿过的固体空间，由一个或多个坐标轴方向上的长方体，即边界箱组成。实体同样拥有各自的边界箱，但处理方法与固体空间不同（除了船）。
- 不要与判定箱相混淆，判定箱指的是玩家可以互动的区域（攻击，挖掘，右键等）。
- 同样不要与模型相混淆，模型只是方块或实体在屏幕上显示的图形。
- 最后，一些方块拥有各自的“效果箱”，如液体，梯子，仙人掌，压力板等。它们拥有特殊的代码与应用。
例如：按钮没有碰撞箱，因此玩家可以从中穿过。但它拥有可以被玩家点击的判定箱。
又例如：屏障方块拥有完全相同的边界箱与判定箱，但是在代码中被强制编写为不显示模型。
本页面列出了 1.8 版本中所有方块的碰撞箱与属性。
拥有特殊属性或没有碰撞箱的方块则提及于各自的页面。
