Read from and write to external .json files using JsonUtilities or LitJson

With JsonUtilities, Unity 5.3 introduced a built-in possibility to interact with JSON-formatted strings. Before, it was common to use third-party libraries, sch as LitJson. Both JsonUtilities and LitJson have their advantages and disadvantages. You can find a comparison on this blog. This repo contains a Unity project with a couple of sample scripts that cover usual use cases with JSON data. At this time (02.2016), there´s not so much documentation about the use of JsonUtilities and about the comparison JsonUtilities and LitJson, so I decided to make some super simple demos.

This project contains sample files (for both JsonUtilities and LitJson) which

• encode basic data objects into a JSON-formatted string and store it into a text file
• load a text file containing a JSON-formatted string and use the data
• put multiple nested data objects into an array and then encode them into a JSON-formatted string
• load a JSON-formatted string, make data changes, add more objects and encode the data into a JSON-formatted string again

Note that JsonUtilities is only available in Unity 5.3 and above.
