That is normal. If plugins are in the habit of returning ChainAction.Fail, then on a production server you would just set your logging level for RoomEventFactory to ERROR instead of WARN. notice that this is a warning, not an error.

[Cusco]

Oh~ Thank you ~

[Cusco]

is a Join Room Event can't pass extra params in to context?

[tcarr]

If a plugin wants to tell a user why it is failing the join room, that's easy. Just have the plugin send a plugin event to the user. The user has to be listening for plugin events of course.

[Cusco]

I mean when I send a JoinRoomEvent to userEnter
Can I send extra param to userEnter?

[Cusco]

what is the UserEnterContext.getResponseParameters() & UserEnterContext.setResponseParameters() can be use for ? Thanks!


// The response esob can be read by the client from the LoginResponse. ( so same as UserEnter )

[tcarr]

Ah I hadn't noticed that before. Looking at the api source code, this should be added to the GenericErrorResponse that is sent to the client. That EsObject would be the extraData attribute on the GenericErrorResponse.

[Cusco]

hmm.. I can't found that GenericErrorResponse in C# Api (can't catch response on JoinZoneEvent and JoinRoomEvent)
which Event/Response handler will it sent to the client? Thanks~

and what if I response ChainAction.OkAndStop in userEnter? What will it passed to next?



@Override
public ChainAction userEnter(UserEnterContext context) {
String userName = context.getUserName();
EsObject response = new EsObject();
logger.debug( LoginInfo.toString() );

EsObject internalExchange = new EsObject();
internalExchange.setString(InteropExchange.SERVERR EQUEST, InteropExchange.ZONING);
internalExchange.setString(InteropExchange.USERNAM E , userName);
EsObject getUserZoneInfo = getApi().callServerPlugin(getApi().getZoneName(), internalExchange);
logger.debug(userName + " ENTERING...");
boolean canZone = getUserZoneInfo.getBoolean(InteropExchange.ZONING, false);
if ( canZone ) {
logger.debug(userName + " have token zoning to " + getApi().getRoomName() );
response.setString(ZoneExchange.ZONEXCHANGE, ZoneExchange.SUCCESS);
return ChainAction.OkAndContinue;
}

if (getApi().isUserLoggedIn(userName)) {
logger.debug(userName + " failed zoning to " + getApi().getRoomName() );

getApi().evictUserFromServer(userName, null);

EsObject ClearUpUserMemoryBuffer = new EsObject();
ClearUpUserMemoryBuffer.setString(InteropExchange. SERVERREQUEST, InteropExchange.REMOVE);
ClearUpUserMemoryBuffer.setString(InteropExchange. USERNAME , userName);
getApi().callServerPlugin(getApi().getZoneName(), ClearUpUserMemoryBuffer);
}
// default Chain Fail
response.setString(ZoneExchange.ZONEXCHANGE, ZoneExchange.FAIL);
return ChainAction.Fail;
}

[tcarr]

If a client fails to join a room, the server sends a GenericErrorResponse. The C# api doc on it is here (http://www.electrotank.com/docs/es5/client/csharp/class_electrotank_1_1_electroserver5_1_1_api_1_1_g eneric_error_response.html).

[Cusco]

Thank you, very nice !!

but Debug.Log ( "Generic Error: " + evt.ErrorType.ToString() + evt.ExtraData.ToString() );
can't get the ExtraData?

[Cusco]

I better to try Plugin Message instead~ Thank again~

[tcarr]

Odds are that the extra data is an EsObjectRO, and there might not be a toString() for that in the C# api. Make an EsObject, use addAll to merge the extra data to it, then toString it. See if that works.

Or just use a plugin message, which is what I've always done when the client needed to know why it wasn't allowed in the room.

Oh wait - if the error is RegistryTransactionEncounteredError then it's not the plugin that is failing the join, it's some other reason. Is there anything in your server logs for this?

[Cusco]

that maybe my coding error in "getApi().evictUserFromServer(userName, null);"
the user kicked out before Chain.Fail ~~



if (getApi().isUserLoggedIn(userName)) {
logger.debug(userName + " failed zoning to " + getApi().getRoomName() );

getApi().evictUserFromServer(userName, null);

EsObject ClearUpUserMemoryBuffer = new EsObject();
ClearUpUserMemoryBuffer.setString(InteropExchange. SERVERREQUEST, InteropExchange.REMOVE);
ClearUpUserMemoryBuffer.setString(InteropExchange. USERNAME , userName);
getApi().callServerPlugin(getApi().getZoneName(), ClearUpUserMemoryBuffer);
}
// default Chain Fail
response.setString(ZoneExchange.ZONEXCHANGE, ZoneExchange.FAIL);
return ChainAction.Fail;

[Cusco]

it works =D

[andrewt]

Yes, but what if there is no error and you just want to send an esobject back to the client after they join a room?

[tcarr]

If you want to send an EsObject to the user *after* they have joined a room, you can using the plugin's userDidEnter method and send a plugin message with the EsObject. If you send a plugin message in the plugin's userEnter method, then the client will get the message before the JoinRoomEvent.
