entities.lua

-- This file contains all entities, including ones that are core prototypes.
--   Core prototypes are named prototypes that the game requires to always exist, for example a "copper-cable" item.

-- These functions are applied directly to the prototype table.
-- This allows to easily create many prototypes that inherit from the same base class/prototype, without copy pasting properties.
