new QuickJoinGameRequest(matchExpression, whereToSearch[, roomToLeave])

Creates a new QuickJoinGameRequest instance. The instance must be passed to the SmartFox.send() method for the request to be executed.

Using this request, by providing a matching expression and a list of Rooms or Groups, SmartFoxServer can search for a matching public Game Room and immediately join the user into that Room as a player.

If a game is found and can be joined, the roomJoin event is dispatched to the requester's client.


This example makes the current user join a a Darts game with a "maximum bet" condition.

function someMethod()
	sfs.addEventListener(SFS2X.SFSEvent.ROOM_JOIN, onRoomJoin, this);

	// Create a matching expression to find a Darts game with a "maxBet" variable less than 100
	var exp = new SFS2X.MatchExpression("type", SFS2X.StringMatch.EQUALS, "darts").and("maxBet", SFS2X.NumberMatch.LESS_THAN, 100);

	// Search and join a public game within the "games" Group, leaving the last joined Room
	sfs.send(new SFS2X.QuickJoinGameRequest(exp, ["games"], sfs.lastJoinedRoom));

function onRoomJoin(evtParams)
	console.log("Successfully joined Room: " +;
