Saving data

[Basirius007]

Hello, I have a question if anybody figured out, how to save data, so when i set up new room there are already player names and their goals, assists and so on that the had in previous room?

You can use localStorage. But localStorage have limitation of ~5mb(depends on browser). If you want to make big storage to store a lot of data, you should look at IndexedDB or make backend server. But I think the simplest way to store a big amount of data is localforage library.

@olegmisar Don't you need to have installed localforge library on server? And by server I mean where haxball.com/headless is hosted. The problem is cross domain policy. I tried setting cors server locally but couldn't connect to haxball using xmlhttprequest....

How have u tried to connect to haxball? Code, please.

function createCORSRequest(method, url) {
  var xhr = new XMLHttpRequest();
  if ("withCredentials" in xhr) {

    // Check if the XMLHttpRequest object has a "withCredentials" property.
    // "withCredentials" only exists on XMLHTTPRequest2 objects.
    xhr.open(method, url, true);

  } else if (typeof XDomainRequest != "undefined") {

    // Otherwise, check if XDomainRequest.
    // XDomainRequest only exists in IE, and is IE's way of making CORS requests.
    xhr = new XDomainRequest();
    xhr.open(method, url);

  } else {

    // Otherwise, CORS is not supported by the browser.
    xhr = null;

  }
  return xhr;
}

var request = createCORSRequest( "GET", "http://localhost:8123/scoreboard.JSON" );
if ( request ){
  // Define a callback function
  request.onload = function(){
      scoreBoard=JSON.parse(request.responseText);
  };
  // Send request
  request.send();
}

I think it was this one. Error was that I can't acces http server on my pc when it's https protocol.

What browser do u use?

chrome

You have to allow mixed content. Here are solutions for different browsers.

@olegmisar That actually worked :D Problem is now that anyone can access my files at 8123 port xD Still I would need to update my whole scoreboard.json everytime some event happens (player scores goal, team wins etc.). I am not so familiar with php to make backend script on my server to fix that. What do you personally use for storing info olegmisar?

[olehmisar]

Maybe I will use IndexedDB. Or localforage library, which is a wrapper for IndexedDB. Localforage is simple to use and doesn't require backend, it saves all the data in browser. But you should read about limitations. I believe that IndexedDB doesn't have limits but I am not sure.

@olegmisar Is there way to update indexeddb store without fetching whole player object , updating it and then using put request to update it?
