So basically, I want to use .json files to store some data for my waypoints instead of using a .txt file like I do now. Now I have never used a .json file before, only edited one for blocks & items/models etc. I have a List that stores all of my waypoints, what I am wondering is how would I go about saving data to a .json file, then read that data to create a waypoint that is then added to the list. Also the main way I would also like to know is how I would format the file to look a bit like this but for every waypoint created:

 

 

{

  {

      "name": "Whateverthenameis",

      "symbol": "SymbolLetter",

      "properties": [

              "coordinates": [

                      "x": whateverx,

                      "y": whatevery,

                      "z:" whateverz

              ],

              "type": whatevertype,

              "scale": whateverscaleasfloat,

              "shown": whatevershown,

      ],

      "world": "WorldFrom"

  },

}

 

 

You need a json serializer/deserializer, don't try to write such a thing yourself.

What Draco said. You can try the GSON library from Google, which should already be included in the workspace.

 

Note that .JSON is technically just text with a specific format - it is often used, for example, to serialize data for storage in a database (e.g. MySQL) or to transmit over a network (e.g. for an AJAX operation). The major benefit of it is that it facilitates the serialization of complex objects or arrays as simple text.

I am aware I need those, but the main thing I am wondering is how to basically read/write the data from/to the json, and create variables for each read value, then convert that into a waypoint with the values.

I think the specifications here are what you're looking for.

 

In other words, in json you have "objects" (they act more like hashmaps, but still). They are enclosed in curly brackets ({}). Each pair consists of a string (a key/field name), and a value (string representation of your data), with a colon ( inbetween them. Commas are sometimes used to separate the key-value pairs. Arrays also exist, and are enclosed in brackets ([]). They contain a list of values, separated by commas.

I know, but the thing is, is how would I go about reading/writing from/to the .json file
