Blocks

A Block is a basic unit of structure occupying space in the world.

A Collision Box is a solid volume of space that the player is not meant to pass through, which consists of one or multiple Bounding Boxes, which are axis-aligned cuboids. Entities have their own bounding box, but are not treated as solid space (except for boats).


 * Not to confuse with a Hitbox, which is a volume of space that a player can interact with (attack, mine, right-click...).


 * Also not to confuse with a Model, which is simply the graphical representation of a block / entity on screen.
 * Finally, some blocks have their own "effect box", such as fluids, ladders, cacti, pressure plates... All of which are coded and applied differently.

For example: a button has no collision box, as the player can walk through one, but has a hitbox which the player can click on.

Another example: a barrier block has overlapping bounding box and hitbox, but is hard-coded to have no model.

This article lists the collision boxes and properties of all blocks in 1.8.

Blocks with particular properties and/or no collision boxes are presented on their own articles.

Simple Collision Boxes
Collision boxes that consist of a single bounding box. Blocks are ordered by length, then width, then height.

Composite Collision Boxes
Collision boxes that consist of two or more bounding boxes.

" Except " represents an intangible zone rather than a tangible one (simpler to describe that listing all bounding boxes)
