Cannot resolve method 'getParentZone()'

[Wei]

I want to create a game room

Code: Select all

try {
            Room nRoom = getApi().createRoom(getParentZone(), cfg, user);
            getApi().joinRoom(user, nRoom);
        } catch (SFSJoinRoomException | SFSCreateRoomException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


but there's an error says Cannot resolve method 'getParentZone()'

so I changed my code to

Code: Select all

Zone zone = getParentExtension().getParentZone();

try {
            Room nRoom = getApi().createRoom(zone, cfg, user);
            getApi().joinRoom(user, nRoom);
        } catch (SFSJoinRoomException | SFSCreateRoomException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


the room was created, but some error message showed

Code: Select all

Your code is correct and there's nothing wrong with getting a referenze to the Zone.
The error says that:

Code: Select all

The provided path is not a directory: extensions/ExtName

which indicates that the path to the Extension you have provided is incorrect and the Extension class could not be loaded.

Cheers

If the Extension class could not be loaded, how could it work? My extension is working, I'm a little confused.

And I still don't know what's wrong with getParentZone(), I saw it almost everywhere, your docs and blog, always

Code: Select all

Room nRoom = getApi().createRoom(getParentZone(), cfg, user);


Do I need to import any class?

[Lapo]

It is referring to the Room Extension.
Your Room creation code specifies an Extension that must be initialized when the Room is created.
That's the one the server is having problems with.

Double check the CreateRoomSettings parameters that you're passing to the createRoom(...) method.
(In other words cfg, in your example code)

Cheers

Thanks man, I modified my code, and it's ok now

Code: Select all

cfg.setExtension(new CreateRoomSettings.RoomExtensionSettings("GameExtension", "com.mazingtec.ftlextension.GameExtension"));
