As in Minecraft, the word "entity" can be used to refer to any objects in the game that are not blocks in the three-dimensional grid that makes up the Lunacraft world. Most of these objects can have a position that is not precisely aligned with the grid, and many of them can be rotated at an arbitrary angle.
The following are all "entities":
- The player
- All Mobs
- Items that you drop by throwing them from your inventory, such as a Magnet or Refined Gold
- Items dropped by a mob after it is killed: Disks and Biogel
- Blocks that have been mined and not yet picked up
- Bullets from the Slugpistol
- Mini Lights
Unlike normal blocks, all entities are visible in complete darkness:
All entities are invisible if they are behind another block, even a highly transparent block such as Glass.

Internally, all entities are stored in a separate file from the terrain (map) data.
