Read from .json file(TypeScript)

[klam A.]

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?

Thanks.

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

function levelRequestListener () {

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

console.log(levels);

}

var request = new XMLHttpRequest();

request.onload = levelRequestListener;

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

request.send();

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);

console.log(levels[0].name);

}

 

Hope this helps.
