Dictionaries

The puzzles from this category allow you to create and operate on dictionary values.

Introduction

Dictionaries are very useful when you need to store, transfer, and retrieve various data in the same entity. Particularly, a dictionary is useful for storing multiple parameters and for passing them in bulk to Puzzles (such as raycast or collision info), JavaScript, or over network.

For example you might define a car with the following dictionary:

...which internally looks like this:


    {
      "available": true,
      "brand": "Tesla",
      "model": "Model S",
      "range": 250,
      "year": 2020
    }

Inside the curly brackets are dictionary items. Each item has a key (e.g. "model") and a value ("Model S") associated with it. Keys are always defined as strings, but values can be of any type (strings, numbers, booleans, lists, other dictionaries, etc.) Also, contrary to lists, there is no particular sorting order applied to dictionary items, so you can add them in arbitrary order.
