Simple Blocks
Blocks are ordered by length, then width, then height.
| Block | Widths (b) | Height (b) | Comments | Image |
|---|---|---|---|---|

| End Portal Frame | 1 × 1 | 0.8125 |  | |
| Enchantment Table | 1 × 1 | 0.75 |  | |
| Bed block | 1 × 1 | 0.5625 | The bottom doesn't look tangible, but it actually is. |  |
| Slab | 1 × 1 | 0.5 | Inversible. |  |
| Daylight Sensor | 1 × 1 | 0.375 |  | |
| Trapdoor (horizontal) | 1 × 1 | 0.1875 | Inversible.

0.125 0.25 0.375 0.5 0.625 0.75 0.875 |

 |
| Wall (2-opposite) | 1 × 0.375 | 1.5 | Centered. Orientable (2 variants).
