  • I'm currently doing a XMLHttpRequest which works fine but holds up the rest of the game until the data is returned.

    How would I keep the game running while the request is going on in the background?

    Current request looks like this: 

    function apiPostRequest(request, body) {
	var xmlHttp = new XMLHttpRequest();
	xmlHttp.open( "POST", baseApiURL + request, false );
	xmlHttp.setRequestHeader('Content-Type', 'application/octet-stream');
	xmlHttp.setRequestHeader('X-Auth-token', token);
	xmlHttp.send(body);
	console.log("Resp: "+xmlHttp.responseText);
	
	resp=xmlHttp.responseText;
	
	return xmlHttp.responseText;
}

    Even if nobody replies, I think that just the act of posting a question here seems to bring about some kind of mystical epiphany.:)

    In case anyone should ever need this; to change this to an asynchronous function which runs while your game is still running, it should be something like this: 

    function apiPostRequest(request, body,runtime) {
	var xmlHttp = new XMLHttpRequest();
	
	xmlHttp.open( "POST", baseApiURL + request, true );//TRUE indicates asynchronous
	xmlHttp.setRequestHeader('Content-Type', 'application/octet-stream');
	xmlHttp.setRequestHeader('X-Auth-token', token);
	
	xmlHttp.onload =function (e)
	{
		
		console.log("Resp: "+xmlHttp.responseText);
		//alert ("Resp :"+xmlHttp.responseText);

		resp=xmlHttp.responseText;
		results=JSON.parse(xmlHttp.responseText);
		
		runtime.globalVars.returned_data = xmlHttp.responseText;
		runtime.callFunction("Event_Got_Data");//call event sheet function once complete

	}

	xmlHttp.send(body);
	
}
