WWW.error

var error: string;

Description

Returns an error message if there was an error during the download (Read Only).

If there was no error, error will return null or an empty string (this is because some platforms don't allow nulls for string values). We recommend that you use String.IsNullOrEmpty to check for the presence of an error so that both cases are covered.

If the object has not finished downloading the data, it will block until the download has finished. Use isDone or yield to see if the data is available.

	// Get a texture with an invalid url
	var url = "invalid_url";
	function Start () {
	     // Start a download of the given URL
	    var www : WWW = new WWW (url);

// Wait for download to complete yield www;

// Print the error to the console if (!String.IsNullOrEmpty(www.error)) Debug.Log(www.error);

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