WWW

Namespace: UnityEngine

Description

Simple access to web pages.

This is a small utility module for retrieving the contents of URLs.

You start a download in the background by calling WWW(url) which returns a new WWW object.

You can inspect the isDone property to see if the download has completed or yield the download object to automatically wait until it is (without blocking the rest of the game).

Use it if you want to get some data from a web server for integration with a game such as highscore lists or calling home for some reason. There is also functionality to create textures from images downloaded from the web and to stream & load new web player data files.

The WWW class can be used to send both GET and POST requests to the server. The WWW class will use GET by default and POST if you supply a postData parameter.

See Also: WWWForm for a way to build valid form data for the postData parameter.

Note: URLs passed to WWW class must be '%' escaped.

Note: http://, https:// and file:// protocols are supported on iPhone. ftp:// protocol support is limited to anonymous downloads only. Other protocols are not supported.

''Note:'' When using file protocol on Windows and Windows Store Apps for accessing local files, you have to specify file:///__ (with three slashes).

Note: The security sandbox present in web-player builds prevents you from accessing content not hosted the server where the webplayer is hosted.

// Get the latest webcam shot from outside "Friday's" in Times Square
var url = "http://images.earthcam.com/ec_metros/ourcams/fridays.jpg";
function Start () {
	 // Start a download of the given URL
	var www : WWW = new WWW (url);

// Wait for download to complete yield www;

// assign texture renderer.material.mainTexture = www.texture; }
