r164: Black screen when running exported projects

  • Problem Description

    After exporting any game with Multiplayer implemented in the project the game will load up with a black screen when reaching in the browser, with only button and textbox objects showing through and music playing. This only occurs with exported versions of the game, the preview version run directly from Construct 2 works normally.

    The following errors are shown in the console in Chrome when running the unchanged, exported form of the Real-Time Multiplayer example:

     Uncaught ReferenceError: cr is not defined 		c2mp.js:811
    C2Multiplayer.doPings 					c2mp.js:811
    (anonymous function) 					c2mp.js:148[/code:se62z37r]
    
    The following error also occurs in Chrome, though less frequently (the errors are cycling down):
    [code:se62z37r] Uncaught ReferenceError: cr is not defined 		c2mp.js:1314
    C2Multiplayer.getHostInputArrivalTime 			c2mp.js:1314
    h.ss 							c2runtime.js:275
    h.Qb 							c2runtime.js:272
    k.Ar 							c2runtime.js:101
    k.Qb 							c2runtime.js:98
    k.setSuspended 						c2runtime.js:84
    window.cr_setSuspended 					c2runtime.js:138
    onVisibilityChanged					index.html:107
    [Construct 2] Suspending [/code:se62z37r]
    
    Also gives more when trying to run the project from a Node.Webkit export:
    [code:se62z37r]Uncaught node.js Error 
    
    ReferenceError: cr is not defined

  • I can also verify this, I've also experience this same issue as GildedFox. The issue only happens when you export your project with Minify enabled.

    Temporary Fix

    Uncheck Minify script box then re-export your project.

    Tested:

    NodeWebkit

    Chrome

    Opera

  • Unchecking minify scripts does the trick. Nice that there's at least a work around so I can get to testing, for now. Thanks!

    I'll add that unchecking the minify script also lets it work in Firefox.

  • Fixed in next build.

  • same problem, here i spent that night solving that,, and finally found that forum.,,, omg lol

    ,,,,,,, i really don't know what I, did but once it was working ............... on googledrive
