Entities have a single bounding box (the player's bounding box is 0.6×1.8×0.6). |- |Collision Box | |A volume of space that the player can physically collide with, specific to blocks though some entities also have one (e.g., boats). A collision box consists of one or multiple bounding boxes; The player's bounding box is not meant to intersect those. |- |Significant angle | |Minecraft works with a limited number of angles for calculations. There are precisely 65536 significant angles. The player's rotation is stored as floats (of which there are much more than 65536).
