Remember that the link structures only allow for 256 characters of identity data.While you're logged into auth, on the “Your Profile” page, click the “Add Service” button at the bottom. We recommend using an easily parseable format like JSON or CSV for encoding the information but this is up to the game. For an example of such a server-side script see the Battlefield 2 mumo plugin. someone is elected squad leader and now can whisper to all other squad leaders and the team leader. Additional information like squad number, squad leader status and so on can be used to trigger even more behavior like automatically maintaining a leadership structure inside Mumble which is kept in-sync with in-game state. This is usually satisfied by the in-game player name or the players ID (player-/connection-ID on the server or a global ID).Īdditionally the identity can contain any additional information about the player that might be interesting for the mumble server.įor example by including team information in the identity a script on the Mumble server can move players into team channels automatically. Identity should contain a string which uniquely identifies the player in the given context. It shouldn't change more than a few times per second if at all during a game. The identity does not need to be updated every single frame. If the camera moves independent of the avatar these values should contain the position, top- and front-vector of the camera. If the camera of your game is not independent of the avatar be sure to copy the avatar values over to the fCameraPosition|Top|Front variables. The coordinate system is a left-handed one, and the units are in meters. fAvatarTop and fAvatarFront should be the orientation. #Mumble link code#Tip: If your game uses a 3D positional audio API such as OpenAL you may want to take a look at the code where the listener gets updated since these APIs usually require the same vectors.įAvatarPosition should be the player position in 3D space, to disable the transmission of positional information alongside audio without unlinking the plugin set x,y,z of the tuple to zero. If you do not supply a top vector, Mumble will assume you have a “Y-is-up” coordinate system and that the user can not tilt their head, and then compute the top vector based on that. The second is the top vector, which is an imaginary vector pointing straight out the top of your head. The first vector is the front vector, which is simply the direction you are looking at. These should be unit vectors (length one), and should be perpendicular (to one another). The reason: If it is not in meters, distance attenuation will be different to the other games/plugins, meaning users will have a bad experience with positional audio (audio configuration is dependant on a common distance measurement). This should be in meters, so you may need to scale it. If you then stretch your arms out in front of you instead, they'll become (0,0,1). In other words, if we place origin in your chest and you stretch your arms out to your sides, your right hand will be (1,0,0), your left hand will be (-1,0,0) and your head will be (0,0.2,0). If you imagine yourself looking over a large empty field X increases towards your right, Y increases above your head, and Z increases in front of you. Mumble, like most sound systems, uses a left handed coordinate system ( see this for a visual representation). 1 #ifdef _WIN32 2 #include 3 #else 4 #include 5 #include /* For O_* constants */ 6 #endif // _WIN32 7 8 9 struct LinkedMem Coordinate system
