Exporting the Matter.js engine world data to JSON format

Is there a way to save my engine.world Object in an exportable format? I attempted converting it to a JSON string using JSON.stringify(engine.world) but encountered issues with the circular structure. Are there any solutions for this problem, or alternative formats that I could use?

I aim to enable users to load custom worlds.

Answer №1

If you're searching for a solution, check out resurrect-js

For converting the data into a string, you can utilize the following code:

let necromancer = new Resurrect();
let data = necromancer.stringify(engine.world);

You have the option to store the variable data as a string in any text file of your choice.

To revert the string back into an object, simply use this piece of code:

let world = necromancer.resurrect(data);
engine.world = world;

I trust this information is useful!
