json

Entities are loaded from .json files in mud/game/.

Each file holds one entity.

The format of the data is a map(dict) of component name to component data

{"id": "rat",
  "living": {"hpmax": 12},
  "mamal": true,
  "weight": 1.2}

The only required component is the 'id', which should have a unique string value.

The 'extends' component is a list of id strings of other entities that are merged into the new entity.

{"id": "mouse",
  "extends": ["mammal", "rodent"],
  "plural": "mice",
  "living": {"hpmax": "2d4"},
  "weight": 0.2}

files called _base_.json are automatically inherited by every file in the current and child directories, facilitating structural organization.
