when a user leaves a gameroom

[Kiv_cg]

using the tic tac toe as a starting point I have written a little multiplayer game using ES. It's almost there but I am not handling users leaving well, but I can't seem to find where it is.


A simple enough question (I am sure I just keep looking straight past it) where is the code that handles a player leaving the game. I want to send a message to tell everyone who has left (using my game id)

hi,

When user lefts room two ES events are fired:

es.userListUpdated (following code is excerpt from ES documentation):


[code]
function userListUpdated(userList:Array, type:String, userReference:Object) {
if (type == "all") {
//The entire list is new
buildUserList(userList);
} else if (type == "userjoined") {
//A user joined the room
addUserToList(userReference);
} else if (type == "userleft") {
//A user left the room
removeUserFromList(userReference);
}
}
es.userListUpdated = userListUpdated;

and second event:

es.usersRenumbered


[code]
function usersRenumbered(userList:Array) {
for (var i:Number = 0; i < userList.length; ++i) {
trace(userList[i].AssignedNumber);
}
}
es.usersRenumbered = usersRenumbered;

I think es.userListUpdated event is in Your TicTacToe code in "game" frame (I write code for AS2, but they look similiar to AS1),

hth,

Peterblaze is right. But to tell you the exact code in the Tic Tac Toe example, here goes

function userListUpdated(userList, type, user) {
 if (user == gamePlayer0 || user == gamePlayer1) {
  //A game player left
  popup.gotoAndStop("Player Left");
 }
}
es.userListUpdated = userListUpdated;

First a function is defined to receive the userListUpdate event. Then it is assigned as an event handler to that event (in the final line).



Every time a user enters or leaves the room this function is called. When the function is called it is given useful information such as 'type' (meaning "userjoined", "userleft", etc), and a reference to the user in question. In the if statement we check to see if the user being referred to is a game player. If it is, then we make the popup window popup and show that the user has left the game.



Of course there is a little more to it beause you had to store the variables called gamePlayer0 and gamePlayer1 earlier. So look in the code to see when and where that was done.

next problem

there are room variables, but it doesn't look like there are game room variables. Am I right?

My problem is this. My game starts with multiple players who get knocked out one at a time. generally the user then leaves the game room, but that means there is a space for someone to come in. I can't think of a way of stopping players joining a game room when the game is in progress but not full. a game room variable would do it, but I don't see them. A room variable is no use as there can be more than one game running at the same time in a room

any ideas

Hi Kiv_cg,

Game rooms are still just rooms. You can still use the same methods to create/update room variables. You should be able to use them creatively to achieve what you are asking about.

Also, you might find AssignedNumber to be useful. Every user in a game room (which is just a room with a few extra features) is assigned a unique number. You can find out a user's number through any user object, like so:

es.getUser().AssignedNumber.value

The above gets your own assigned number. If your number is 0, then you have been in the room longer than anyone else. It is common in 2 player games to allow usrs with assigned numbers of 1 and 0 to play the game. If a user has an assigned number of 2 or greater, then they are spectators.

If you have users 0, 1, 2, 3, 4 and user 2 leaves, then 3 and 4 get renumbered to 2 and 3.

my first attempt at using this failed - it looked like the room variable was in the lobby rather than the game. I must have set it up at the wrong place.
