Hi,

I've been working on a multiplayer game. I followed the instructions in the pong multiplayer that comes with the scirra sample projects. I was able to establish the connection between Host and Peer, and host is displayed on the Peer side but the Peer is being created at (0,0) instead of the defined area.

Looks like Peer is not able to sync to Host or the host is not updating the sync values properly. I'm not sure where it went wrong. Can you please check the code and help me with it?

Please check the gameplay for better understanding -

Thanks in advance. Please let me know if you need any further information.

[Multiplayer]

----+ System: GamePlay = "multi"

--------[Signalling]

// On start of layout, connect to the signalling server. We also set up which client input values the peers will be using, and sync the Peer object with its position and additional instance variables for the look position, current inputs and player stats.

------------+ System: On start of layout

-------------> Multiplayer: Add client input value tag "x", precision Low (int16, 2 bytes), interpolation None

-------------> Multiplayer: Add client input value tag "y", precision Low (int16, 2 bytes), interpolation None

-------------> Multiplayer: Add client input value tag "points", precision Low (int16, 2 bytes), interpolation None

-------------> Multiplayer: Add client input value tag "player", precision Low (int16, 2 bytes), interpolation None

-------------> Multiplayer: Sync Creators (with Position only, precision Low (int16, 2 bytes) at Normal bandwidth (unpredictable))

-------------> Multiplayer: Sync Creators variable Points (precision Low (int16, 2 bytes), interpolation: None, client value tag: "points")

-------------> Multiplayer: Sync Creators variable Player (precision Low (int16, 2 bytes), interpolation: None, client value tag: "player")

-------------> Multiplayer: Connect to signalling server "wss://multiplayer.scirra.com"

// When connected, request to log in.

------------+ Multiplayer: On signalling connected

-------------> Multiplayer: Log in with alias "Sud"

-------------> TextCoins: Set text to "Connected to server"

// When logged in, request to join the room. Use auto-join to assign pairs of players in to separate rooms.

------------+ Multiplayer: On signalling logged in

-------------> Multiplayer: Auto-join from room ROOM_NAME for game GAME_NAME instance INSTANCE_NAME (max peers: 2, lock when full)

-------------> TextCoins: Set text to "Logged in with alias: " & Multiplayer.MyAlias & " (" & Multiplayer.MyID & ")" & newline & "Joining room..."

// We joined the room: activate either the Host or the Peer group.

------------+ Multiplayer: On signalling joined room

// As the host, we also adopt the existing paddle object on the left of the layout as our own. We must set its peer ID to our own ID and tell the Multiplayer object it is associated with ourselves.

----------------+ Multiplayer: Is host

-----------------> TextCoins: Set text to "Joined Room as Host"

-----------------> System: Set group "Host" Activated

-----------------> Creators: Set peerid to Multiplayer.MyID

-----------------> Multiplayer: Associate Creators with peer Multiplayer.MyID

// When not the host, the paddle object already in the layout is destroyed. 'Sync object' will create both paddles, and they'll be associated with the correct player using the 'On created' trigger in the 'Peer' group. Also since the game is 2-player, it can begin as soon as the peer joins since we know the host is already there, so update the game state to "getready".

----------------+ System: Else

-----------------> TextCoins: Set text to "Joined Room as Guest"

-----------------> System: Set group "Peer" Activated

----------------+ Multiplayer: On peer message "gamestate-changed"

-----------------> System: Set GameState to Multiplayer.Message

------------[Host]

// As the host, when a peer joins we create a new paddle for them on the right. 'Sync object' will cause it to be created for the peer too. We also begin the game: we set the state to "getready" for 3 seconds, then upon "go" we set the ball moving and 1 second later set the state to "started" (so the score appears instead of "GO!").

Hi,

I used this function many times in C2, I'm not sure why I'm not able to make it work in C3. Probably I might have missed something.

This is how it should work.

When I add names, it should display them below by creating a new button but it is not happening.

Can anyone help me with setting the create-object function? I have added the events but not sure why it is not creating a new button.

Please let me know you need any further information.

Thanks in advance.
