Hi. English is not my native language, so sory for my mistakes. I make game in VisualStudio(TypeScript), and create 

levels in Tiled Map Editor. So my questions is: how I can read information in my TypeSript game from level.json file?

Simplistically speaking, you could load it with an AJAX call and parse the JSON:

function levelRequestListener () {

var levels = JSON.parse(this.responseText);



var request = new XMLHttpRequest();

request.onload = levelRequestListener;

request.open("get", "level.json", true);


You could take this up a level by writing an interface to describe the levels structure so you could get type checking and auto-completion on the levels variable...

interface Level {

id: number;

name: string;


function levelRequestListener () {

var levels: Level[] = JSON.parse(this.responseText);




Hope this helps.
