Multiplayer Bug in Chrome

  • Problem Description

    The multiplayer real time game tutorial is having synchronization issues on Chrome.

    Attach a Capx

    (I must have been away for too long, can't see the attach a file button in posting/editing)

    Description of Capx

    Multiplayer - real time game tutorial. The only modification made was to change the game name to scirra-gametutorial4 so as to have a personal testing room.

    Steps to Reproduce Bug

    • Step 1 - Open the Multiplayer Tutorial
    • Step 2 - Change the GAME_NAME variable to some other value such as "scirra-gametutorial4".
    • Step 3 - Run layout (in firefox), enter an alias and press the Join button.
    • Step 4 - Copy the URL and start the game in a second tab in firefox and in a tab in Chrome

    Observed Result

    • The player on Chrome cannot damage the player(s) on firefox. Also has problems moving.
    • The player on Chrome occasionally has very high latency and PDV.
    • When the game was run in 2 tabs in chrome, both players disappeared from the game.

    Expected Result

    All players can damage the other players normally, and move correctly.

    Low latency due to all tabs/browsers being on the same machine with the same connection.

    Affected Browsers

    • Chrome: YES
    • FireFox: NO
    • Internet Explorer: Cannot run multiplayer plugin

    Operating System and Service Pack

    Windows 7 Ultimate, Service Pack 1

    Construct 2 Version ID

    Release 208 (64-bit) checked

  • No, it does happen, and I know why. When you have 2 tabs, and move to 1 tab, the game on the tab in the background gets suspended. If you put the tab of the 'host' in the background (and thus opening the peer tab) the host gets suspended triggering this disappearing.

    2 open windows however is no problem, as long as the host is visible on-screen.
